contractor qualifications as stated within the contract specifications.
The successful bidder must be a “responsible contractor.” The term “responsible contractor” means a
contractor as defined in Minnesota Statutes, section 16C.285, subdivision 3. Any prime contractor,
subcontractor, or motor carrier that does not meet the minimum criteria or fails to comply with the
verification requirements is not a responsible contractor and is not eligible to be awarded a construction
contract for the project or to perform work on the project. A prime contractor, subcontractor, or motor
carrier that makes a false statement under oath verifying compliance with the minimum criteria will be
ineligible to be awarded a construction contract on the project, and the submission of a false statement
may result in termination of a contract awarded to a prime contractor, subcontractor, or motor carrier
that submits the false statement. A prime contractor shall include in its verification of compliance a list
of all of its first-tier subcontractors that it intends to retain for work on the project. Before execution of a
construction contract, a prime contractor shall submit a supplemental verification under oath confirming
that all subcontractors and motor carriers that the prime contractor intends to use to perform project
work have verified to the prime contractor, through a signed statement under oath by an owner or
officer, that they meet the minimum criteria for a responsible contractor.
The City of Golden Valley reserves the right to reject any and all Bids, to waive irregularities and
informalities therein and to award the Contract in the best interests of the City of Golden Valley.

2. EXAMINATION OF PLANS, SPECIFICATIONS AND SITE OF WORK
The Bidder shall examine to their satisfaction the quantities of work to be done as
determined from the Plans and Specifications. Quantities indicated by the
Engineer on drawings or elsewhere are estimated only, and Bidders must rely on
their own calculations. Bidders shall be thoroughly familiar with the
Specifications, including all Special Conditions.
Submission of a bid by the Bidder is a representation that the Bidder has visited the
Work site, become generally familiar with local conditions under which the Work is

and groundwater, availability of drainage, the obstacles which may be encountered,
means of approach to the site, manner of delivering and handling materials,
facilities of transporting and installing construction plant and equipment and all
other relevant matters pertaining to the complete execution of this Contract. No
plea of ignorance of conditions that exist or that may hereafter exist, or of difficulties
that will be encountered in the execution of the work hereunder, as a result of
failure to make necessary examination and investigations, will be accepted as a
sufficient excuse for any failure or omission on the part of the Contractor to fulfill in
every detail all the requirements of this Contract, or will be accepted as a basis for
any claim whatsoever for extra compensation or for an extension of time. No
Bidder may rely upon any statements or representations of any officer, agent, or
employee of the City with reference to the conditions of the work or the character of
the soil or other hazards that may be encountered in the course of construction.
Submission of a bid by a Bidder is a representation that the Bidder has contacted
the affected utilities listed in Item 18 of the Special Conditions prior to submitting
the bid to determine the extent of their facilities within the project area and the
scope and anticipated schedule of the facility relocation, removal or adjustment.

9. REJECTION OF BIDS
The City reserves the right to reject any and all bids, including without limitation;
proposals that show any omission, alteration of form, additions not called for,
conditional bids or alternate bids not specified or irregularities of any kind.
Proposals in which the prices are obviously unbalanced may be rejected.
10. WITHDRAWAL OF PROPOSALS
A Bidder may withdraw its Proposal without prejudice to themselves, provided a
written request is filed with the City Clerk before the hour of letting, and such
withdrawn Proposal may be modified and resubmitted by the Bidder at any time
prior to the hour set for receiving bids.
11. PUBLIC OPENING OF PROPOSALS
Proposals will be opened publicly and read aloud in such place as designated at
the time and the date set in the “Advertisement for Bids.” Bidders or their
authorized agents are invited to be present.
12. EVALUATION OF BIDS
The City will review the completed Contractor Questionnaire, included within the
Proposal Form, to determine whether the Bidder has the practical knowledge,
experience, available personnel, equipment and financial resources for the timely
and professional completion of the work. The City also reserves the right to make
inquiries regarding past performance of any Bidder on previous contracts. The
object of this review and any other inquiries is to provide the City with the best
available information regarding the capabilities of the Bidder to complete the work
as specified in the Contract Documents, and to minimize the risk of awarding the
Contract to an unqualified Bidder.
Bidders are required to submit evidence that they have practical knowledge of the
particular work bid upon and that they have the financial resources to complete the
proposed work. The City reserves the right to reject any Proposal where there is
insufficient or unsatisfactory evidence to demonstrate the Bidder’s ability to perform
IB-4
the work. Failure on the part of any Bidder to have carried out previous contracts
satisfactorily, to show adequate experience, or to possess necessary equipment or
labor for completion of the work, shall be sufficient cause for disqualification of the
Bidder. Bidders who will subcontract more than 50% of the value of the work
under the Contract shall be deemed unqualified to perform the work.
The City will award the Contract to the Bidder whose bid price, quality and
experience best conform to the overall interests of the City. Bids from qualified
bidders will be considered as described in the City of Golden Valley General
Conditions, Section II.1 CONSIDERATION OF BIDS. The City’s decisions
regarding bidder qualifications, contract award and contract amount shall be final.
The City has limited financial resources to commit to the project. Accordingly,
the project must be accomplished with a minimum of interruption, on time and
without cost overruns. The City believes that a contractor with sufficient
experience in constructing this kind of specialty roadway is necessary for this
complicated project. Therefore, the City will consider the quality and experience
of each Bidder in addition to the bid price.
A Bidder will not be considered for this project unless the Bidder receives a rating
of at least 10 points, as determined by the City, using the following system for
assigning points:
Experience constructing an urban street reconstruction
project similar in size and functions within the last five
years, to the satisfaction of the City
5 points
For each additional project qualifying under the
above category 1 point each
Experience of the assigned job superintendent in
supervising construction of an urban street reconstruction
project while under traffic similar in size and functions
within the last five years, to the satisfaction of the City
5 points
For each additional roadway supervised that
qualifies under the above category 1 point each
History of initiating change orders (not at the owner’s
request) that total more than 5% of the original bid within
the last five years
Deduct 2 points
for each confirmed project
History of complaints regarding completion deadlines or
the quality of the work of projects within the last five years
Deduct 2 points
for each confirmed project
The City may give partial credit for points depending upon the
nature of the projects.
13. DISQUALIFICATION OF BIDDERS
More than one Proposal for the same project from an individual firm, partnership,
company or corporation under the same or different names will not be
considered. Evidence that any Bidder is interested in more than one Proposal for
the same work will result in the rejection of all such Proposals. Collusion
between Bidders shall be sufficient cause for the rejection of all bids so affected.
Failure to achieve a rating of 10 points or more as described in section 9 above
shall be sufficient cause to disqualify a Bidder for this project.
IB-5
14. EQUIPMENT
When requested by the City, the Bidder shall furnish a complete statement of the
make, size, weight (where weight is one of the specified requirements), condition
and previous length of service of all equipment to be used in the proposed work.
15. SUPPLIERS AND SUBCONTRACTORS
The Bidder shall provide, within the time requested, a list of all suppliers and
subcontractors to be used on the project for approval by the City. All provisions of
Item 12 of these instructions shall also apply to subcontractors and suppliers. The
Bidder will be notified in writing by the City of disqualification of any supplier or
subcontractor. The Bidder will then be given the option to replace the disqualified
supplier or subcontractor with an approved supplier or subcontractor or withdraw
its bid. No adjustment of bid prices will be allowed for such replacement.
16. FURNISHING OF EVIDENCE OF RESPONSIBILITY
When requested by the City, the Bidder and any subcontractors shall furnish a
balance sheet, certified by a Certified Public Accountant, dated not more than sixty
(60) days prior to date of the opening of the Proposal which shall set forth
outstanding assets and liabilities in reasonable detail. The City may also require
the Bidder and its subcontractors to furnish a list of work of similar nature
performed with dates of completion thereof. The Bidder or subcontractor shall also
furnish any other additional information relative to financial responsibility and
competence to do the work as may be requested by the City prior to acceptance of
any Proposal.
17. REQUIREMENTS OF CONTRACT BOND
The successful Bidder, at the time of execution of the Contract, shall furnish and at
all times maintain a satisfactory and sufficient bond in the full amount of the Contract
as required by law with a corporate surety satisfactory to the City. The form of bond
is that required by Statute. Personal sureties will not be approved.
18. FAILURE TO EXECUTE CONTRACTS
Failure to furnish the Contract Bond in a sum equal to the amount of the award, or
to execute the Contract within ten (10) days as specified, shall be just cause for the
annulment of the award and, in the event of the annulment of the award, the
amount of the guaranty deposited with the Proposal shall be retained by the City,
not as a penalty, but as liquidated damages.
19. AWARD OF CONTRACT
If the Contract is to be awarded, the City Council will award the Contract to the
Bidder whose bid is in the best interest of the City. Award will be based on the
Base Bid, plus any bid alternates the City may include.

right to require additional information before approving the award of the Contract to a
Contractor. This may be done to help qualify subcontractors for bidding to better
determine the contractor’s qualifications for bidding the work.
The contents of this questionnaire will be private until the City has completed the
selection process. At that time, all information will become public, except information
that qualifies as trade secret data under Minnesota Statutes Section 13.37.

require additional information, including a financial statement, or it may determine that
the Bidder is unqualified to bid the project.

in the City charging Contractor, and withholding any monies due as
liquidated damages, the amount of $2,000 per calendar day until all Work is
completed.
If Contractor is delayed for any reason in the commencement or performance of
the Work, to the extent such delay will prevent the Contractor from completing
the Work (or any portion thereof) within the Contract Time, Contractor’s sole
remedy for such delay shall be an extension of the Contract Time. All such
extension requests shall be made according to the requirements and procedures
set forth in Division I, 1806 (Determination and Extension of Contract Time) and
1403 (Notification for Contract Revisions) of the MnDOT shall apply, except as
modified or supplemented in these Special Conditions.
SC-3
Without limiting the foregoing, if a conflict arises with existing private utilities
during the commencement or performance of the Work, Contractor shall proceed
to work in areas without such conflict until the conflicts are resolved. It is the
express understanding of the parties with regard to all Work that Contractor will
undertake its performance in a manner to avoid or minimize any delays that may
result from private utility conflicts or any other possible causes of delay.

work to minimize inconvenience to residents.
This project shall be divided into three (3) areas for project scheduling.
This Work must be completed according to the following phasing requirements.
Contractor shall submit to the Engineer for review and approval, a detailed
critical path phasing plan and schedule a minimum of one (1) week before
the pre-construction conference. The schedule must detail all controlling
operations. The following requirements/operations must be included in this
plan:
A. Installation of sanitary sewer liners (mains and services) before
installation of wear course. Once the existing concrete pavement is
removed on a street, work must proceed in a continuous manner until it
is completed. Contractor must schedule the Work to avoid time when
there is no work progressing on any given street.
B. Driveway replacement within the required time constraints.
C. Landscape restoration within the required time constraints.
D. Completion of the Project by the specified dates.
E. Once Contractor has raised all castings to their final grade, it must allow
two (2) weeks in each area for City staff to televise existing and new
sewers before the wear course is placed. Contractor shall ensure that all
work on sewer manholes, catch basins and sewer lines is completed, and
they are cleaned to the Engineer’s satisfaction before any televising is
performed. If the sewers are determined, at any time during televising
operations, to need any additional cleaning, the City will, at their
discretion, clean them with their own staff (at $420/hour with a four-
hour minimum) or retain a cleaning service to perform cleaning on all
sewers remaining to be televised. All costs for such cleaning will be
billed to the Contractor or withheld from monies due.
Working hours for this project shall be limited to 7:00 a.m. to 7:00 p.m., Monday
through Saturday, except as otherwise stated in the Contract Documents, unless
approved in writing by the City Engineer. Contractor shall schedule its work to
comply with this requirement.
Contractor shall perform some Work at times other than those indicated if
the Engineer deems it is in the best interest of the City and the property
SC-4
owners affected. No claims for extra compensation will be considered for

materials.
No removal items, spoil or aggregate piles will be allowed within rights-of-way
overnight except by express, written consent of the Engineer. In the event piles
are left in the rights-of-way at the end of the day, the City may, at its
discretion and without prior notification to Contractor, remove all piles with
its own or contracted forces. All costs associated with such removal shall
be billed to Contractor or withheld from monies due.
14. MAINTENANCE OF EXISTING CITY UTILITIES: The City has cleaned and
televised all sanitary sewer lines and storm sewer lines prior to construction.
Contractor shall be responsible for keeping all utilities clean during construction
including but not limited to gate valve stacks, utility lines, and manholes. In the
event debris is found during the post-construction televising of sewers, the
City may, at its discretion, clean all remaining sewers to be televised with
its own or contracted forces. All costs associated with such cleaning shall
be billed to Contractor or withheld from monies due.
15. CONSTRUCTION STAKING: The City, or its representative, will set
construction stakes, lines, elevations and grades for this construction as deemed
necessary by the Engineer. The stakes established by the City will constitute the
field control Contractor will use to perform the Work. It will be Contractor’s
responsibility to request any additional staking necessary to perform the Work.
SC-7
Contractor’s superintendent shall notify the Inspector a minimum of 48 hours in
advance of the need for construction stakes. This advance notification
requirement must be strictly adhered to. No claims for down time or delays in
work due to Contractor’s negligence to request staking as described will be
permitted. Contractor shall be obligated to prepare the entire area to be staked
before requesting staking. Failure to prepare the area to the Engineer’s
satisfaction shall result in staking delays until the area is prepared properly. No
claims for lack of stakes or schedule delays will be considered that are due to not
properly preparing such areas.
Contractor shall be responsible for the preservation of all stakes and marks
established by the City or its consultants. If the Engineer determines that
construction stakes have been carelessly or willfully destroyed or disturbed by
Contractor or by Contractor’s lack of protection of the stakes, the cost of
replacing the stakes will be deducted from monies due Contractor.
The City will provide Contractor with written notice of violation of this Section one
time. This written notice shall serve as notice of withholding of monies due
Contractor so the City may recover its costs for failure to comply with this
requirement.
16. QUALITY CONTROL AND QUALITY ASSURANCE TESTING: Contractor shall
be responsible for quality control testing in accordance with the current Schedule
for Material Testing found on the MnDOT website
http://www.dot.state.mn.us/materials/lab.html., as amended in these

required by MnDOT and approved by the Engineer. Certification of such
experience shall be submitted to the Engineer at the pre-construction
conference.
Contractor shall also cooperate with the Engineer in collecting companion
samples in accordance with MnDOT Specifications to verify Contractor’s test
results. Collecting companion samples shall be considered incidental for which
no direct compensation shall be made. The City will be responsible for testing
such samples provided by Contractor at its cost. The Engineer shall contact
Contractor so he may be represented during sampling, and assist as necessary.
17. PROJECT ACCESS AND STAGING AREA: Construction traffic access to the
Project areas shall be limited to City streets being reconstructed under this
project, and federal, state and county highways and City streets as approved by
the Engineer, or as otherwise noted in the plans.
The use of other non-designated routes shall be cause for ticketing. This
requirement shall not waive Contractor’s obligation to comply with existing
statutes, local ordinances, or any other existing laws; nor shall it waive the
SC-8
governing authority from assigning penalty for violating such statutes, ordinances
or laws.
Construction staging area to be submitted and approved by the City. This
requirement shall not waive Contractor’s obligation to comply with existing
statutes, local ordinances or any other existing laws; nor shall it waive the
governing authority from assigning penalty for violating such statutes, ordinances
or laws.
No extra compensation will be allowed for extra construction
costs due to these restrictions.
18. UTILITY CONFLICTS: In order to minimize inconvenience to adjacent property
owners and expedite the Project, Contractor shall be expected to coordinate its
efforts with the private utility companies so the Work can be done in a timely
manner. Contractor shall schedule or redirect its Work to ensure that utility
company relocates, installations and/or removals do not impede progress of the
Project. Contractor shall also coordinate all unanticipated utility relocations or
adjustments determined to be necessary to complete the Work. The City will be
responsible for costs incurred by the utility companies for unanticipated
relocations and adjustments only in cases where prior, written authorization to
perform the utility work is provided by the Engineer.
Contractor waives claims for any and all costs or damages due to alleged delay,
disruption or acceleration, and releases the City from any such claims, to the
extent the claim is due to the failure of any private utility with facilities affected by
the Project to promptly relocate, remove, or adjust such facilities.
CenterPoint Energy (CPE) will be upgrading and/or replacing gas mains in the
Project area as part of this project. Contractor is expected to coordinate
construction operations with CPE so all Work can be done in a timely manner

for extra compensation to perform the Work in accordance with the Plans
that are due to conflicts with in-place utilities shall be considered.
Likewise, no claim for delays due to conflicts with in-place utilities shall be
considered. (Also see Special Conditions Section 4 with regard to utility
company requirements)
19. EASEMENTS AND PERMITS: The City shall work to obtain all required
permanent and temporary easements and permits for this project with the
exception of the following:
A. The construction activities, methods and procedures used on this Project
shall comply with and be done in accordance with the General Permit
Authorization to Discharge Storm Water Associated with a Construction
Activity under the National Pollutant Discharge Elimination System/State
Disposal System Permit Program. Therefore, prior to beginning the Work,
the City and Contractor as a co-permittee will be required to obtain a permit
from the Minnesota Pollution Control Agency (MPCA). The Storm Water
Pollution Prevention Plan (SWPPP) is included in the Plan. The Contractor
shall file required construction Storm Water permit online with the MPCA
(https://rsp.pca.state.mn.us/TEMPO_RSP/Orchestrate.do?initiate=true).
The permit becomes valid one business day after Contractor submits a
completed application online. Contractor shall email the permit to the City
permit once obtained.
In addition to establishing legal accountability by the co-permittee on this
Project, the general permit shall serve to modify the Minnesota Department
of Transportation (MnDOT) Standard Specifications for Construction and all
supplements thereto. All permit requirements pertaining to construction
practices, application of erosion control methods and devices, and
implementation time requirements are hereby incorporated into the
Construction Specifications by reference and are made both integral and
enforceable parts of the Contract.
The weekly inspection and maintenance requirements of said general
permit (Part IV.E) shall be the responsibility of Contractor. All site
inspections shall be completed in accordance with the requirements
specified in the permit. An inspection form will be supplied by the City. It
shall be Contractor’s responsibility to provide blank copies of the log sheet
as necessary for the life of this Contract. The active and completed
inspection forms shall be kept on the Project site in a secure, weatherproof
location, and shall be accessible by both Contractor and City personnel at
all times. This information shall also be made available to any other
interested party upon request. Contractor shall provide copies of the
previous week’s original inspection form to the Engineer at every
weekly construction meeting. The inspection form will be filed with the
Project’s SWPPP.
SC-10

A. Erosion and Sediment Control Permit from Bassett Creek Watershed
Management Commission (BCWMC). Contractor shall be required to fulfill all
requirements and provide any bonds required of the permit.
B. Department of Health permit for water main replacement work. Contractor
shall be required to fulfill all requirements of this permit.
20. DRIVEWAY CONSTRUCTION ON PRIVATE PROPERTY: Residential property
owners with driveways disturbed as part of this street improvement project will be
given the opportunity to reconstruct their entire driveway at contract unit prices.
(No adjustments to any pay items associated with driveway reconstruction will be
permitted due to increases or decreases in quantities due to Work on private
property). The estimated quantities may not reflect all of the proposed private
driveway Work. The Engineer shall set a reasonable deadline for residents to
return their agreements, and Contractor shall be obligated to perform all such
Work as ordered by the Engineer. Contractor shall cooperate with the
Engineer to ensure timely completion of Private Driveway Construction.
Claims by the Contractor for delays caused by not receiving this information to
coincide with the Work schedule will not be allowed.
Some driveways, requested by residents to be replaced, may require the
Contractor to assume a higher degree of liability to construct than a normal
driveway, or on which the ability to achieve the required quality is not possible
(i.e., too much or not enough slope, landscaping impacts, construction along a
foundation, etc.). If Contractor deems this to be true, it may make a request to
the Engineer to remove the driveway from the Work. The Engineer shall
consider all such requests; however, the decision of whether or not the driveway
shall be included in the Work shall be at the sole discretion of the Engineer. If
the Engineer deems the driveway is within the scope of the Contract Work, the
Contractor shall be obligated to perform such Work in accordance with all
Specifications herein.
Contractor shall be responsible to establish grades for all private driveways. The
City may be available, with advanced notification, per Contractor’s request to
help assist in establishing grades.
Contractor shall be required to notify the property owners 48 hours in
advance of performing work on private driveways. Failure to provide such
written notification shall result in Contractor delaying the Work until the
SC-11
proper notification is provided. No claim for extra compensation to adhere to
this requirement shall be considered.
21. MEASUREMENT AND PAYMENT: Payment for all items shall be by the unit
price bid.
Items on the Proposal Form have been listed in a logical order. However, items
from any section may be used for like work on any part of this project, not only
the section they are listed under. No claims for additional compensation for use
of an item for work under a different section will be considered.
Measurement for all items not specifically described in these Specifications shall
be done in accordance with MnDOT Standard Specifications.
Contractor shall submit all final quantities to the City within one month after wear
course paving. Should Contractor’s final quantities not be submitted within the
required time, it shall be understood that the City’s Quantities for the Work are
accepted by Contractor.
Unclassified work authorized by the Engineer, will be paid for on a force account
basis according to Section VIII, Item 8 of the General Conditions.
22. TREE AND LANDSCAPE PRESERVATION: Significant care must be taken to
protect existing trees and shrubbery that the Engineer feels may be impacted by
the construction. Contractor shall meet with the Assistant City Forester
(763.593.3976) on-site to review procedures for successful protection of
trees throughout the construction process. Special care must be taken when
in close proximity to any such vegetation to prevent unnecessary cutting,
breaking, or shredding of roots; wounding or scraping of trunks; smothering of
root systems by stockpiling of construction materials or excavated materials
within their drip lines; excess foot or vehicular traffic; or parking of vehicles within
their drip lines.
Contractor shall install tree protection fencing, as directed by the Engineer in the
field. The unit price bid per linear foot shall be considered compensation in full to
place and maintain all such protection throughout the construction.
Contractor shall exercise due caution to protect existing tree branches. All
branches that have been damaged by Contractor shall be properly trimmed in
accordance with National Arboriculture Standards by the end of the workday.
Contractor shall also notify the Engineer immediately of any damaged branches.
When excavating near trees, Contractor shall cut cleanly back to the soil line, all
exposed, shredded or torn roots greater than 1-½” in diameter, with proper
pruning equipment. The cost to cut roots shall be incidental for which there shall
be no direct compensation. When excavating or sloping within fifteen (15) feet of
any tree, Contractor shall coordinate all such efforts with the Assistant City
Forester. Standard excavation procedures may need to be modified for large
SC-12
trees that have their trunks closer than five (5) feet from the excavation or sloping
limits.
Contractor shall be required to provide protection to all exposed oak tree roots
that are cut prior to July 1. Contractor shall have on-site an approved wound
dressing to be applied to freshly cut root ends immediately (within 10 minutes)
after excavation to prevent oak wilt infection. Wound dressing will not be
permitted for any other situation other than oaks damaged by construction before
July 1. Contractor shall coordinate all such work with the Assistant City Forester.
23. RESPONSIBILITY FOR DAMAGE CLAIMS (1714): The provisions of MnDOT
Specification 1714 are supplemented as follows:
Contractor must have the City of Golden Valley, and Short Elliott
Hendrickson Inc. named as additional insureds on any insurance
coverage Contractor is required to provide.
24. MOBILIZATION (2021): The lump sum for mobilization is to include all aspects
of work in accordance with MnDOT Specification 2021, for the base bid. No
measurement for Mobilization shall be made for Bid Alternates A or B.
25. CLEARING AND GRUBBING (2101): In an effort to minimize tree removals,
Contractor shall be obligated to remove trees at any time throughout the duration
of the Work. Contractor’s bid price shall take into consideration multiple
mobilizations. Contractor shall notify the Engineer of any trees he/she feels
must be removed to complete the Work as specified. The Engineer may wait
until all subgrade correction and/or sloping near such questionable trees is
complete to determine the necessity of removals. No claims for extra
compensation shall be considered due to Contractor’s compliance with this
requirement. Clearing and grubbing shall be performed in accordance with the
provisions of MnDOT Section 2101, and the following:
The Engineer shall mark all trees, shrubbery and other items designated for
clearing and grubbing, after grade stakes have been established. Only those
trees and items as marked may be removed. Any items removed or
damaged by Contractor not marked for removal will be Contractor’s
responsibility to replace at its sole cost. All replacement items must be
approved by the Engineer. Only the Engineer or his designate is
authorized to mark trees, brush or shrubs for any purpose or in any
manner. In addition, Contractor shall ensure that trees/landscaping not
designated for removal are not damaged, marked or defaced in any way.
Grinding of stumps will not be permitted. Stumps must be dug out.
All trees cleared and grubbed shall be promptly disposed of off the site with
no additional compensation. Disposal must be in accordance with all county
and state disposal requirements. Contractor shall not leave removed trees,
stumps or debris on the Project site overnight.
SC-13
Measurement for clearing and grubbing trees shall be the individual tree,
or by the acre, as specified in the Plans or as directed by the Engineer.
Payment for clearing and grubbing trees under these items is for trees four
(4) inches in diameter and larger (measured at a point 24-inches above
the ground) only, and shall be considered compensation in full to remove
each tree and stump as directed by the Engineer. Removal and disposal
of all trees, brush and shrubs smaller than four (4) inches in diameter shall
be considered incidental for which no direct compensation shall be made.
No claims shall be considered for extra costs due to size for clearing
and/or grubbing trees or shrubs as directed by the Engineer. Trees,
stumps, brush and shrubs the Engineer designates to be removed in
conjunction with private driveway construction, as part of this project, shall
be performed and compensated for in accordance with this Specification.
Once the Engineer marks trees and shrubs for removal, Contractor shall
promptly remove such items and dispose of them off the Project area.
26. REMOVALS AND SALVAGES (2104): The unit price bid for all items
designated for removal shall include disposal at a site selected by Contractor and
approved by the Engineer. Items designated to be removed must be loaded and
taken from the Project area as they are removed. In no case will removal
items be allowed to remain on the Project overnight without written
consent of the Engineer. Failure to comply with this requirement may result in
the City withholding all money due until removal items have been disposed of off
the Project.
Residents with driveways disturbed as part of the Work will be given the
opportunity to replace their entire driveways in conjunction with the Project.
Removals of bituminous or concrete driveway pavement shall be compensated
for under the unit price bid for the type of pavement removed, and shall be
considered compensation in full for such Work as directed by the Engineer. No
claims for extra compensation or unit price adjustment will be considered due to
increased or decreased quantities for private driveway work.
Contractor shall be required to remove all pavement against building
foundations, panels or existing retaining walls by hand to prevent damage
to the in-place structure. All such extra equipment and labor, including but not
limited to, jackhammers, compressors, etc., shall be considered incidental to the
unit price bid for such removal.
Contractor shall salvage all items designated to be reused on this project as
directed by the Engineer. The City has no areas contiguous to the Project for
stockpiling salvaged bituminous pavement. Items damaged by the Contractor
that are designated to be salvaged shall be replaced at the Contractor’s
expense.
If there are existing mailboxes that must be removed to construct the Project,
Contractor shall salvage and reset them at the end of the Project. During the
Project, Contractor must provide a temporary bank of mailboxes to allow mail
SC-14
delivery by the U.S. Postal Service. Contractor shall coordinate the temporary
mailbox locations with the local post office. These locations shall also be
approved by the Engineer. The temporary mailbox bank shall be considered
incidental to salvage mailbox and support.
The unit price bid, per square yard, to Remove Concrete Pavement (P),
regardless of existing pavement thickness (see chart in plan for existing concrete
thickness) shall be considered compensation in full to remove the full depth of all
concrete from the roadway (including integral curb and any reinforcement that
may be present). No measurement will be made for items designed as plan
quantity (P). In order to maintain temporary vehicle access during construction,
concrete pavement shall be removed half at a time on each street as needed to
replace existing water main. Contractor shall dispose of the material at no
additional cost in accordance with all applicable rules and regulations. No
payment for additional mobilizations to remove concrete pavement in phases will
be made.
Bituminous pavement designated to be removed (driveways, bituminous curb,
and small miscellaneous bituminous pavements), shall be disposed of by

previous field installations in the USA of the same resin system and tube
materials as proposed for the actual installation. These test results must
verify that the CIPP physical properties specified have been achieved in
previous field applications. Testing samples for this project shall be made
and tested at the Contractor’s expense.
It shall be the responsibility of the City to provide locations of all manhole
access points. Contractor shall be responsible for making the manholes
accessible for the Work. Any traffic control deemed necessary by the
Engineer shall be provided by Contractor, and included in the lump sum
price for Traffic Control.
1. CIPP liner insertion shall be performed in accordance with the
manufacturer’s recommendations, and in such a way to fully extend
SC-54
the tube to its termination point, hold the tube tight against the pipe
wall, and produce dimples at service connections and flared ends
at maintenance holes. Lubricants may be used as necessary.
Care shall be taken so as not to over-stress the liner material.
2. Temperature gauges shall be placed to determine the temperature
of the incoming and outgoing water from the heat source. Another
such gauge shall be placed inside the tube at the remote end to
determine the temperature at that location during the cure cycle.
Contractor shall supply a suitable heat source and water circulation
equipment to deliver hot water throughout the section to be cured
by means of a pre-strung hose to uniformly raise the water
temperature above the temperature required to effectively cure the
resin in accordance with the manufacturer’s recommendations.
3. Contractor shall maintain the manufacturer’s recommended
hydrostatic pressure and temperature throughout the curing
process and for the duration recommended by the manufacturer.
Compressible gases such as air or steam shall not be used.
4. Initial cure shall be considered complete when the exposed
portions of the pipe are hard and sound and the remote
temperature sensor indicates that the temperature is high enough
to create an exotherm.
5. Contractor shall slowly cool the hardened pipe liner in a
temperature below 100 degrees F before releasing the hydrostatic
pressure. Cool down may be accomplished by introducing cool
water into the inversion standpipe to replace water drained from a
small hole placed in the downstream end. Final pressure release
shall be slow to avoid development of a vacuum in the newly
formed pipe liner.
6. A tight seal shall be achieved at the ends of the liner. If this is not
achieved, then a seal must be achieved by applying a coating of a
resin mixture compatible with the liner material at the manholes.
7. Steam curing shall not be used unless Contractor meets the
following qualifications:
a. Contractor shall be licensed and certified by the
manufacturer of the CIPP Lining process and have
successfully completed at least 5 CIPP Lining Projects and
aggregate length of at least 10,000, of which 2,000 linear
feet must be greater than 9-inch pipe using steam curing.
b. Each installation crew must be directly supervised by a
dedicated foreman having previously supervised the
successful installation of at least 5 CIPP Lining Projects and
aggregate length of at least 10,000, of which 2,000 linear
feet must be greater than 9-inch pipe using steam curing.
Contractor shall reopen branch connections to buildings without
excavation using a remote-controlled cutting device monitored by a
video television camera.
SC-55
Contractor shall certify he/she has a minimum of two (2) complete working
cutter units plus spare key components on the site before each lining
process begins.
After the sewer lining is complete, Contractor shall re-establish all
active service connections as soon as practical and before any
adverse effect is experienced by the resident. Contractor shall
determine active services during pre-construction televising.
If Contractor is unable to re-establish sewer service connections inside the
pipe and excavation is necessary, the cost and liability of such excavation
shall be the responsibility of Contractor, including any additional
landscaping or turf establishment.
Significant wrinkles, as determined by the Engineer, shall be cause for
rejection of the liner. Rejected liners shall be completely removed and the
pipes relined to provide a smooth pipe interior. The cost for all such
removals and relining shall be borne by Contractor.
Contractor shall warrant and save harmless the City against all claims for
patent infringement and any loss thereof.
C. Increased or Decreased Quantities: No consideration will be given to
requests for extra compensation due to increased or decreased quantities.
81. SANITARY SEWER SERVICE WYE SEALING VIA GROUT PACKER
INJECTION METHOD (BID ALTERNATE A): Work shall consist of sealing
sanitary sewer lateral service connections identified by the City.
Contractor shall:
A. Provide all labor, materials, tools, equipment, and incidentals as shown,
specified, and required to seal pipeline joints and lateral connections to
the mains using the packer injection method. The effective sealing length
of the lateral connection shall be a minimum of 18 inches from the
connection to the main
1. Packer injection sealing is used to reduce the infiltration within the
pipeline, seal annular space between liners and host pipes, seal
pipe joints that have failed the joint test criteria, provide external
pipe support, but not a structural rehabilitation, by stabilizing soils
outside the pipe and prevent further loss of pipe bedding into the
pipe.
2. Packer injection sealing shall be accomplished by pressure
injection of chemical grout into the soils encompassing the exterior
of pipe joint. Chemical grouts shall be designed to be injected into
the soil surrounding the pipe, which stabilizes the soil and forms a
permanent impermeable seal called a grout/soil ring, and into the
annular space between liners and host pipes. Adequate volumes of
SC-56
grout must be injected to form an effective seal. Adequate amounts
of grout are based generally upon pipe size and field conditions.
This application will be through structurally sound joints and lateral
connections through penetrations from within the pipe by using the
packer method in tandem with a CCTV inspection system.

EXECUTION
A. CONTROL TESTS
1. Packer Tests - Demonstrate the acceptable performance of air test.
a. To insure the accuracy, integrity and performance
capabilities of the testing equipment, a demonstration test
will be performed in an above-ground 8” nominal diameter
test cylinder suitable to contain the full length of the packer
and sustain the void test pressure. The test cylinder shall be
equipped with a void release valve to exercise a controlled
release of pressurized air from the void area to test the
packer under both sound and leaking conditions. The test
cylinder shall also be equipped with a local pressure gauge
(0-25 psi) within the void space.
i. With the void release valve sealed, inflate the packer
and air test void at 7-10 psi. The observed void
pressure at the test cylinder pressure gauge must be
within ±1.0 psi of the reading in the control center/studio
void pressure gauge and follow both up and down
pressure changes (allowing time for pressure
equalization).
SC-62
ii. If above test is passed, crack the release valve to
simulate a very small leak. The cylinder shall be
equipped with a void release valve to exercise a
controlled release of the test media with the associated
pressure drop to be equally displayed ±1.0 psi of the
cylinder gauge and test monitoring equipment.
b. After entering each pipeline segment with the test
equipment, but prior to the commencement of joint testing,
position the packer on a section of sound sewer pipe
between pipe joints, and perform a test as specified. The
equipment shall hold a 7-10 psi test pressure for a period of
15 seconds with a pressure drop of less than 1 psi. In the
event of a failed test, repair any defective equipment and re-
test to verify proper operation of all equipment at no
additional compensation. Should it be found that the surface
or porosity conditions of the barrel of the sewer pipe cannot
meet the joint test requirements, then the performance
testing shall be waived or modified as determined by the
Engineer.
c. If air testing cannot be performed successfully, repair or
otherwise modify air test equipment and repeat the tests.
This test may be required at any other time during the
performance of joint testing work if the Engineer suspects
the testing equipment is not functioning properly.
2. Pump Tests - At the beginning of the contract, prior to application of
grout, perform a pump test to determine if proper ratios are being
pumped from the grout component tanks at the proper rates and to
measure pump rates. Use separate containers to capture the
discharges from each of the grout component hoses, to simulate
the actual volumes of each component through the interconnect
hoses, hose reel and length of grout hose and confirm accuracy of
grout pump totalizer. Take corrective action if ratios or rates are
not within manufacturer’s recommended standards.
3. Grout Tests - Perform and record a grout gel test in the presence of
the Engineer by recording the grout tank solution temperature,
catalyst tank solution temperature, ambient air temperature in truck,
and gel time of the sample whenever the following conditions occur:
a. At the beginning of each day; the material in the hoses shall
be recycled to the tanks and a sample shall be taken.
b. When new batches of grout are mixed.
c. Whenever the temperature in the tanks or ambient
temperature have changed by more than +/- 10°F from the
previous gel test.
B. PIPE PREPARATION
1. Prior to the application of the chemical grout materials, Contractor
shall thoroughly clean the sewer designated to receive the chemical
SC-63
grout. Cleaning shall constitute removal of all roots and loose
debris and solids which inhibit proper seating of the packer.
Removal of hardened materials such as concrete shall be
considered beyond the scope of this work.
2. The City shall have cleared the designated sewer line(s) of
obstructions such as dropped joints, protruding lateral connections,
and broken pipe / crushed pipe which will prevent the use of the
grouting equipment. If the CCTV inspection reveals a condition for
which an applicable pay item has not been included on the
Schedule of Prices, Contractor shall inform the Engineer. Engineer
may choose to make a point repair or will direct Contractor to
abandon the section of pipe or lateral connection scheduled for
sealing.
C. GROUT PREPARATION
1. Follow the manufacturer’s recommendations for the mixing and
safety procedures.
2. Adjust gel time as necessary to compensate for changes in
temperature in grout component tanks or hoses. The addition of
dilution water to extend gel times is not acceptable unless resulting
base grout tank only material exceeds 20% by weight for solution
grouts.
3. During the grouting process, the Grouting Technician shall monitor
the grout component tanks to make sure that proper ratios are
being pumped. If unequal levels are noted in the tanks, repeat the
pump test as described above and correct any defective
equipment.
4. Gel times shall be calculated using the following formula unless
Contractor experience and/or field conditions dictate otherwise.
Any alterations of the gel time formula shall be approved by the
Engineer.
5. Packer/Pipe void shall be defined as the volume between the
inflated packer and the inside pipe wall when the packer is inflated
per manufacturer recommendations. For example: an 8” pipe with a
packer void space of 0.3 gallons and a 3 gpm pumping rate would
provide
D. TESTING AND SEALING DEFECTS

2. Testing and Sealing will not be required on pipe exhibiting the
following conditions or characteristics:
a. Longitudinally cracked, fractured or broken pipe.
b. Sections of the pipe with structural defects between joints.
c. Any sections of pipe or joints or lateral connections that are
in such poor structural condition that in the judgment of
Engineer or Contractor, significant structural damage of the
pipe would occur as a result of testing or sealing.
3. Any structurally undamaged joint that structurally fails (breaks)
during testing and sealing that are documented on video to have
been done under normal pressure conditions shall be the City’s
responsibility and cost to repair.
4. Seal all circumferential cracks and fractures or other defects as
specified or as directed by Engineer. Do not test or seal any other
pipe defects unless so specified or shown, or directed by Engineer
to do so. Any structurally failed pipe or joint that is sealed at the
Engineer’s direction that further fails/breaks during testing and
grouting that are documented on video to have been done under
normal pressure conditions shall be the City’s responsibility and
cost to repair. Promptly repair any other sewer damage resulting
from Contractor’s operations at no additional compensation.
E. LATERAL CONNECTION TESTING PROCEDURE
1. Lateral connection joint testing pressure shall be equal to 0.5 psi
per vertical foot of pipe depth plus 2 psi; however, test pressure
shall not exceed 10 psi without approval of the Engineer.
2. Air testing lateral connections shall be accomplished by isolating
the area to be tested with the lateral connection packer and by
applying positive pressure into the isolated void area. A pan and tilt
camera shall be used to position the lateral packer for laterals
directly connected to the mainline sewer. The lateral bladder shall
be inverted from the mainline assembly into the lateral pipe and
inflated. The mainline elements shall then be inflated to isolate the
lateral connection and the portion of the lateral to be tested. A
sensing unit shall monitor the pressure of the packer void and will
accurately transmit a continuous readout of the void pressure to the
control panel at the grouting truck or to a pressure gauge on the
packer recorded by the CCTV camera.
3. The test procedure will consist of applying a controlled air pressure
into each isolated void area. Air shall then be slowly introduced
into the void area until a pressure equal to or greater than the
required test pressure, but in no cases greater than 2 psi above the
required test pressure, is observed on the pressure monitoring
equipment. Once the designated pressure in the isolated void is
displayed on the meter of the control panel, the application of air
pressure will be stopped and a 15 second waiting period will
commence. The void pressure will be observed during this period.
SC-65
If the void pressure drop is greater than 2.0 psi within 15 seconds,
the lateral shall be considered to have failed the air test and shall
be grouted and retested.
4. After completing the air test for each individual lateral specified
herein, deflate the lateral packer, with the void pressure meter
continuing to display void pressure. If the void pressure does not
drop to 0.0 +/- 0.5 psi, the equipment shall be adjusted to provide a
zero void pressure reading at the monitor.
F. SEALING GENERAL
1. Seal all joint and lateral connections that failed the pressure test, or
as specified or as directed by the Engineer, by the injection
method. This shall be accomplished by forcing grout through a
system of pumps and hoses into and through the joints of the sewer
from the packer within the sewer pipe. Remove excess grout from
pipe and laterals. Excess grout shall be defined as a thickness of
grout that given its location, size and geometry, could cause a
blockage. Flush or push forward to the next downstream manhole,
remove from the sewer system, and properly dispose of excess
grout.
G. LATERAL CONNECTION SEALING FROM THE MAINLINE BY PACKER
INJECTION GROUTING
1. Lateral connection sealing begins if the lateral connection does not
pass the air test, shows evidence of leakage, has been successfully
cleaned to remove roots, or where Contractor has been directed.
The lateral packer shall remain in position during the pressure test,
thus maintaining the isolated void. Pressure inject grout through the
lateral packer into the annular space between the lateral sealing
plug and the lateral pipe.
2. When pumping grout, operate the pumps until the mixed grout has
flowed through any joint failure, through any annular space, and
into the surrounding soil; gelled or filled the available void space;
formed a cohesive seal stopping further grout flow; and minimum of
8 psi back pressure is achieved while pumping. As grout pumping
continues the void pressure will slowly rise to a range of about 2 to
4 psi, continue pumping until a point where there is a sudden
increase in the void pressure. This increase from 2 to 4 psi to over
8 to 10 psi takes place in a matter of a few seconds. If the grout
pumped exceeds 1 gallon per foot of lateral bladder plus 3 gallons,
it will be suspected that there are significant voids on the outside of
the pipe or that the packer is not properly sealed. Check that the
packer is sealed properly. If it is, modify grouting procedure to
stage grouting by pumping additional grout equivalent to1 gallon
plus 0.25 gallon per foot of lateral bladder, waiting 1 full minute, and
retesting. The maximum number of stages shall not exceed two
stages unless authorized by Engineer.
SC-66
3. Upon completion of the lateral connection sealing procedure,
deflate the lateral bladder, re-inflate and air test the lateral
connection a second time to confirm the sealing of the connection
in accordance with the air testing procedure. If the lateral
connection fails this air test, repeat the grouting procedure at no
additional cost to the City, except for the additional grout used. Air
tests after grouting laterals containing roots is not required.
4. Confirm lateral flow after sealing of each lateral connection. If a
grout blockage exists, Contractor shall immediately clear the lateral
at no additional cost to the City. Blockages in the lateral that are
not the result of sealing operations shall not be the responsibility of
Contractor.
5. After sealing lateral connections (with the appropriate size lateral
bladder), a thin residual grout film may be present inside the lateral
wall. The amount of residual grout film present is dependent on the
lateral bladder used, geometry of the lateral and positioning of the
packer. This thin layer of cured grout is normal and will eventually
peel off the sidewall of the pipe. The residual chemical grout film is
not “sandwiched” between two structures and will eventually peel
off the sidewall of the pipe. This residual chemical grout film is not
considered excess grout.
H. JOINT / LATERAL CONNECTION SEALING VERIFICATION
1. Record sealing of joints in conjunction with the testing of joints.
Record the void pressure drop continuously on video and in writing
immediately before and after sealing. After the packer is deflated
and moved, record on video the visual inspection of the joint.
2. Use of standardized test and seal data sheets and PACP data
codes is highly recommended.
I. DISPOSAL
1. Collect and properly dispose of cleaning materials used in the
cleaning of the sealing and grout mixing equipment.
J. POST-CONSTRUCTION INSPECTION
1. Conduct Post-Construction Inspection of lateral and mainline
utilizing CCTV.
2. Upon completion of sealing lateral connections, notify the Engineer
so that the Engineer may be present during the CCTV inspection of
the sealed lateral connections to verify that no infiltration is present.

of delivering air, steam, or water, as required by the liner system
manufacturer, uniformly throughout the section to achieve a consistent
cure of the resin. If using hot air or steam, slowly bleed in heated air to
control the initial rise in liner temperature such that heating air temperature
rises no more than 3 degrees Fahrenheit per minute. Maintain the curing
temperature recommended by the liner system manufacturer. Prevent
SC-73
excessive temperatures that could scald or bubble the liner. Scalded or
blistered liner will be rejected if, in the opinion of the Engineer, the
performance of the liner is compromised.

CIPP shall remain in the host pipe. Provide a finished CIPP that is
continuous and free as commercially practicable of visual defects such as
foreign inclusions, dry spots, pinholes, delamination, and wrinkles in any
location in excess of 10% of the host pipe inside diameter. Verify there is
no potential for obstruction of flow.
J. If a point repair is required after the liner has cured, use a tube segment
with compatible (preferably identical) properties as the existing liner to
splice across the point repair. Point repair shall extend a minimum of 12
inches on each side of the defect.
Post-Construction Inspection of Completed Work
A. Conduct Post-Construction Inspection of service and mainline connection.

items. Such changes shall not invalidate the Contract. If quantities originally
contemplated are materially changed, Contractor shall request a cost adjustment in
writing in compliance with the Change Order requirements set forth in Section 3
herein. Approval of any such cost adjustment shall be at the sole discretion of the
Engineer and the Engineer’s decision shall be final on any and all matters
concerning cost adjustment. No payment for changed items shall be made to
Contractor until both parties have signed the Change Order.
Except in the case of minor changes in the Work approved or ordered by the
Engineer in accordance with Section III (3)(D), or ordered by the Engineer in
accordance with Section III (3)(C), Contractor may make substitutions only with the
consent of the City, after evaluation and written approval by the Engineer and in
accordance with a Change Order.
CHANGES IN THE WORK
A. GENERAL
Changes in the Work may be accomplished after execution of the Contract, and
without invalidating the Contract, by Change Order, Construction Change Directive
or order for a minor change in the Work, subject to the limitations stated in this
Section and elsewhere in the Contract Documents. A Change Order shall be based
upon agreement between the City and Contractor. A Construction Change Directive
may be issued by the Engineer and may or may not be agreed to by Contractor. An
order for a minor change in the Work may be issued by the Engineer alone and shall
not involve a change in the Contract Price or Contract Time. Changes in the Work
shall be performed under applicable provisions of the Contract Documents.
Contractor shall proceed promptly with changes in the Work, unless otherwise
provided in the Change Order, Construction Change Directive, or order for a minor
change in the Work.
B. CHANGE ORDERS
A Change Order is a written instrument prepared by the Engineer and signed by the
City and Contractor stating their agreement upon all of the following:
i) The change in the Work;
ii) The amount of the adjustment, if any, in the Contract Price; and
iii) The extent of the adjustment, if any, in the Contract Time.
C. MINOR ALTERATIONS OF PLANS OR CHARACTER OF WORK
The Engineer may order minor changes in the Work that are consistent with the
intent of the Contract Documents and do not involve an adjustment in the Contract
Price or Contract Time. The Engineer’s order for minor changes shall be made in
writing. If Contractor believes that the proposed minor change in the Work will affect
the Contract Price or Contract Time, Contractor shall notify the Engineer and shall
GC - 6
not proceed to implement the change in the Work. If Contractor performs the Work
set forth in the Engineer’s order for a minor change without prior notice to the
Engineer that such change will affect the Contract Price or Contract Time,
Contractor waives any adjustment to the Contract Price or extension of the Contract
Time.
D. ELIMINATION OF WORK
Should the City eliminate any Contract items from the Contract, delete any Work, or
order termination on a Contract item before completion of that unit, Contractor shall
be reimbursed for all costs incurred prior to notification that are not the result of
unauthorized work. Compensation will be made on the following basis:
i) Accepted quantities of Work completed in accordance with the Contract will
be paid for at the Contract prices.
ii) For materials that have been ordered but not incorporated in the Work,
reimbursement will be made in accordance with the procedure set out for
Surplus Material.
iii) For partially completed items, accepted Work shall be paid for on the basis of
a percentage of the Contract bid price equal to the percentage of actual
accomplishment toward completion of the item. In arriving at this percentage,
the value of materials incorporated in the partially completed items will be
considered to be the actual purchase price of the materials, plus
transportation costs, to which will be added fifteen percent (15%) of the sum
thereof.
Contractor shall also be reimbursed for such actual expenditures for equipment,
mobilization, and overhead as the City considers directly attributable to the
eliminated work and that are not recovered as part of the direct payment for the
Work.
Payment for completed Work at the Contract prices and for partially completed Work
and materials in accordance with the above provisions, together with such other
allowances as are made for fixed costs, shall constitute final and full compensation
for the Work related to those Contract items that have been partially or totally
eliminated from the Contract.
UNCLASSIFIED WORK
All work and materials that are not included under any items in the Proposal or
Contract Documents and for which a unit price has been submitted, shall be
designated as Unclassified Work.
Before any Unclassified Work is performed, the Engineer shall submit to Contractor
for its acceptance, a Change Order stating the location, nature, estimate of
quantities, and basis of payment of work to be performed. When this Change Order
has been signed by both parties, it shall become part of the Contract.
GC - 7
Any Change Order shall stipulate a unit price or lump sum for the performance of
work. Where a change in the Contract Price or Contract Time cannot be agreed
upon, the Unclassified Work shall be completed pursuant to a Construction Change
Directive and payment shall be made on a Force Account basis.
CONSTRUCTION CHANGE DIRECTIVES
A Construction Change Directive is a written order prepared by the Engineer
directing a change in the Work prior to agreement on adjustment, if any, in the
Contract Price or Contract Time, or both. The City may by Construction Change
Directive, without invalidating the Contract, order changes in the Work within the
general scope of the Contract consisting of additions, deletions, or other revisions,
the Contract Price and Contract Time being adjusted accordingly. A Construction
Change Directive shall be used in the absence of total agreement on the terms of a
Change Order.
If the Construction Change Directive provides for an adjustment to the Contract
Price, the adjustment shall be made as provided in Section VIII below. If Contractor
disagrees with the adjustment in the Contract Price or Contract Time, Contractor
may make a Claim in accordance with applicable provisions of Section VIII(6).
Upon receipt of a Construction Change Directive, Contractor shall promptly proceed
with the change in the Work involved and advise the Engineer of Contractor’s
agreement or disagreement with the method, if any, provided in the Construction
Change Directive for determining the proposed adjustment in the Contract Price or
Contract Time. When the City and Contractor agree with a determination made by
the Engineer concerning the adjustments in the Contract Price and Contract Time, or
otherwise reach agreement upon the adjustments, such agreement shall be effective
immediately and the Engineer shall prepare a Change Order. Change Orders may
be issued for all or any part of a Construction Change Directive. A Construction
Change Directive signed by Contractor indicates Contractor’s agreement therewith,
including adjustment in Contract Price and Contract Time or the method for
determining them. Such agreement shall be effective immediately and shall be
recorded as a Change Order.
FINAL CLEAN-UP
Upon completion of the Work and before acceptance, issuance of the Certificate of
Final Completion and final payment, Contractor shall remove from the street and
adjacent property, all surplus and discarded materials, equipment, rubbish and
temporary structures; restore in an acceptable manner all property, both public and
private, which has been damaged during the prosecution of the Work; and shall
leave the site in a neat and presentable condition subject to the approval of the
Engineer.
GC - 8
SECTION IV - CONTROL OF WORK
AUTHORITY OF ENGINEER
The Engineer shall decide any and all questions which may arise as to (1) the quality
and acceptability of materials furnished and Work performed; (2) the manner of
performance and rate of progress of the Work; (3) the interpretation of the Plans and
Specifications; (4) the acceptable fulfillment of the Contract on the part of Contractor;
and (5) the amount and quantity of the several kinds of Work performed and
materials furnished under the Contract.
CONFORMITY WITH PLANS AND ALLOWABLE DEVIATIONS
No deviations from the Plans or the approved working drawings shall be permitted
without the written approval of the Engineer.
COORDINATION OF PLANS AND SPECIFICATIONS
Contractor shall take no advantage of any apparent error or omission in the Plans or
Specifications, and the Engineer shall be permitted to make such corrections and
interpretations as may be deemed necessary for the fulfillment of the Plans and
Specifications.
Any work not specified herein or in the Plans, but which may be fairly implied or
understood as included in the Contract, shall be completed by Contractor without
extra charge. Any ambiguity or discrepancy in the Plans or Specifications shall be
adjusted by using the best class of work or materials.
In the case of any discrepancy between the scale and figures in the Plans, drawings,
etc., the figured dimensions shall govern. In the case of any discrepancy between
the quantities shown in the Proposal and those shown in the Plans, the Plans shall
prevail. In case any other discrepancy occurs between the Plans and the
Specifications, the decision of the Engineer shall be decisive thereon.
COOPERATION BY CONTRACTOR
The City shall supply Contractor with five copies of the Plans and Specifications.
Contractor shall have said Plans and Specifications available at the Project at all
times during the prosecution of the Work. Contractor shall give the Work its
constant attention to facilitate progress and shall cooperate with the Engineer in
setting and preserving stakes, benchmarks, etc., and in all other things that are
necessary for satisfactory completion of the Work. Contractor shall have a
competent and reliable superintendent acting as Contractor’s representative on the
job at all times. This representative shall supervise all of Contractor’s workforce,
including its subcontractors, during all phases and in all aspects of the Work. All
orders from the Engineer shall be directed through the superintendent.
GC - 9
Contractor shall provide a list, as deemed necessary by the Engineer, of emergency
contacts, including names and 24-hour telephone numbers, to the City.
CARE AND PROTECTION OF WORK AND MATERIALS
From the commencement of the Work until the final acceptance of the same,
Contractor shall be solely responsible for the care of the Work and for the materials
delivered to the site and intended to be used in the Work. All injury or damage to the
same from whatever cause, shall be made good at Contractor’s expense.
Contractor shall provide suitable means of protection for and shall protect all
materials intended to be used in the Work and shall provide similar protection for all
Work in progress as well as completed Work. Contractor shall at all times take all
necessary precautions to prevent injury or damage to the Work in progress,
including but not limited to protection for damage or injury caused by flood, freezing,
or inclement weather of any kind. Only approved methods shall be used for this
purpose.
AUTHORITY AND DUTY OF INSPECTOR
The Inspector shall be authorized to inspect all Work and materials furnished. Such
inspection may extend to all or any part of the Work and to the preparation or
manufacture of the materials to be used. An inspector shall be stationed on the
Work to report to the Engineer as to the progress of the Work and the manner in
which it is being performed. The Inspector shall also report to the Engineer
whenever it appears that the materials furnished or the Work performed by
Contractor fail to fulfill the requirements of the Specifications and Contract, and shall
bring any such failure or other infringement to Contractor’s attention. Such
inspection, however, shall not relieve Contractor from any obligation to perform all of
the Work strictly in accordance with the requirements of the Specifications.
In case of any dispute arising between Contractor and the Inspector as to materials
furnished or the manner of performing the Work, the Inspector shall have the
authority to reject materials or suspend the Work until the questions at issue can be
referred to and decided by the Engineer. If Contractor uses rejected materials or
fails to suspend the Work, all Work performed by Contractor under such suspension
or rejection shall be considered unauthorized work and subject to rejection or
replacement by Contractor at Contractor’s expense. The Inspector shall not be
authorized to revoke, alter, enlarge, relax or release any requirements of these
Specifications nor to approve or accept any portion of the Work, or to issue
instructions contrary to the Plans and Specifications. The Inspector shall in no case
act as foreman or perform other duties for Contractor, nor shall the Inspector
interfere with the management of the Work by Contractor.
Any advice that the Inspector may give to Contractor shall in no way be construed as
binding upon the City in any way, nor shall any such advise release Contractor from
fulfillment of the terms of the Contract.
GC - 10
INSPECTION
The Engineer or the Engineer’s representative shall be allowed access to all parts of
the Work at all times and shall be furnished such information and assistance by
Contractor as may be required to make a complete and detailed inspection. Such
inspection may include mill, plant, or shop inspection of materials and workmanship.
UNAUTHORIZED WORK
Work done without lines and grades, Work done beyond the lines and grades shown
on the Plans, or as given, except as herein provided, or any Unclassified Work done
without written authority shall be considered unauthorized and at the expense of
Contractor and will not be measured or paid for by the City. Work so done may be
ordered removed and replaced at Contractor's expense.
DEFECTIVE WORK
All Work not conforming to the requirements of the Contract Documents shall be
considered defective and may be rejected by the Engineer by providing written
notice of the defect to Contractor. Contractor shall promptly correct Work rejected
by the Engineer or failing to conform to the requirements of the Contract Documents
and whether or not fabricated, installed or completed. Costs of correcting such
rejected Work, including additional testing and inspections, the cost of uncovering
and replacement, and compensation for the Engineer’s services and expenses
made necessary thereby, shall be at Contractor’s expense.
Should Contractor fail or refuse to remove or renew any defective Work, or to make
any necessary repairs in an acceptable manner and in accordance with the
requirements of the Contract Documents within the time indicated by the City, the
Engineer shall have the authority to cause the unacceptable or defective Work to be
removed and renewed or repaired at Contractor's expense. Any expense incurred
by the City in making these removals, renewals or repairs, which Contractor has
failed or refused to make, shall be paid for out of any monies due or which become
due Contractor, or may be charged against the Contract Bonds. Continued failure or
refusal on the part of Contractor to make any or all necessary repairs promptly, fully
and in an acceptable manner shall be sufficient cause for the City, at its option, to
purchase materials, tools and equipment, and employ labor or to contract with any
other individual, firm or corporation, to perform the Work. All costs and expenses so
incurred shall be charged against Contractor and the amount thereof deducted from
any monies due or which may become due to Contractor under this Contract, or
shall be charged against the Contract Bonds. Any work performed, as described in
this section, shall not relieve Contractor in any way from its responsibility to perform
the Work.
The City shall also have authority to take over and use defective Work without
compensation to Contractor, when Contractor fails or refuses to rebuild such
defective Work.
GC - 11
FINAL INSPECTION
The Engineer will make final inspection of all Work, and any portion thereof, as soon
as practicable after notification by Contractor that such Work is nearing completion.
If the inspected Work is not acceptable to the Engineer at the time of the Engineer’s
inspection, the Engineer shall advise Contractor in writing as to the particular defects
to be remedied. If, within a period of ten (10) days after such notification, Contractor
has not taken steps to speedily complete the Work as directed, the Engineer may,
without further notice and without in any way impairing the Contract, make such
other arrangements as the Engineer may deem necessary to have such Work
completed in a satisfactory manner. The cost of completing such Work shall be
deducted from any monies due, or which may become due Contractor on the
Contract.
GUARANTEE
In addition to Contractor’s obligations under Section IV paragraph 9, if, within one
year after the date of Final Completion of the Work, or by terms of any applicable
special warranty required by the Contract Documents, any of the Work is found to be
not in accordance with the requirements of the Contract Documents, Contractor shall
correct it promptly after receipt of notice from the City to do so, unless the City has
previously given Contractor a written acceptance of such condition. The City shall
give such notice promptly after discovery of the condition. If, during the one-year
period for correction of Work, the City fails to notify Contractor and give Contractor
an opportunity to make the correction, the City waives the right to require correction
by Contractor and to make a claim for breach of warranty. If Contractor fails to
correct nonconforming Work within a reasonable time after receipt of notice from the
City, the City may correct the Work at Contractor’s expense.
The one-year period for correction of Work shall be extended with respect to
portions of Work first performed after Final Completion by the period of time between
Final Completion and the actual completion of that portion of the Work. The one-
year period for correction of Work shall not be extended by corrective Work
performed by Contractor pursuant to this Section.
Nothing contained in this Section shall be construed to establish a period of
limitation with respect to other obligations Contractor has under the Contract
Documents. Establishment of the one-year period for correction of Work as
described in this Section relates only to the specific obligation of Contractor to
correct the Work, and has no relationship to the time within which the obligation to
comply with the Contract Documents may be sought to be enforced, nor to the time
within which proceedings may be commenced to establish Contractor’s liability with
respect to Contractor’s obligations other than specifically to correct the Work.
GC - 12
FOSSILS
If any fossils or treasure or other unusual or valuable geological formations are
found in the process of excavating, such fossils and sample of geological formations
shall be carefully preserved by Contractor and given to the Engineer and shall be the
property of the City.
SECTION V - CONTROL OF MATERIALS
SOURCE AND QUALITY OF MATERIALS
The source of supply of the materials to be used shall be approved by the Engineer
before delivery is started. The approval of the source of any material will stand only
so long as the material itself conforms to the Specifications. Only materials
conforming to the requirements of these Specifications shall be used in the Work.
The source of any materials shall not be changed at any time without the written
approval of the Engineer. Contractor may be required, at any time, to furnish a
complete statement of the original composition and manufacturer of any or all
materials required in the Work, or to submit sample of the same.
STANDARD STOCK PRODUCTS
All materials, supplies and articles furnished shall, whenever so specified, and
otherwise wherever practicable, be the standard stock products of recognized,
reputable manufacturers. The standard stock products of manufacturers other than
those specified may be accepted when it is proved to the satisfaction of the Engineer
that they are equal to or better than the specified products in strength, durability,
usefulness and convenience for the purpose intended. Whenever reference is made
herein to A.S.T.M. Specifications, it shall be understood that the latest revision of the
A.S.T.M. at the time of award of Contract is implied.
TESTS OF MATERIALS
When tests of materials are necessary, such tests shall be made by and at the
expense of the City unless otherwise provided. Contractor shall afford such facilities
as the Engineer may require for collecting and forwarding samples, and shall not use
the materials represented by the samples until tests have been made and the
materials have been found to satisfy the requirements of these Specifications.
Contractor shall, in all cases, furnish the required samples without charge. The
quantity of materials Contractor must furnish shall be a reasonable amount, deemed
by the Engineer, to effectively test such materials to verify compliance with the
Specifications and/or meet requirements from non-City funding sources.
GC - 13
STORAGE
Materials shall be stored so as to insure the preservation of their quality and fitness
for the Work and such materials, even though approved before storage, shall be
subject to test, and must meet the requirements of these Specifications at the time it
is proposed to incorporate them in the Work. Materials shall be stored in a manner
that will facilitate inspections and protect the general public from injury.
The portion of the right-of-way not required for public travel may, with the consent of
the Engineer, be used for storage purposes, and for the placing of Contractor's plant
and equipment, but any additional space required, unless otherwise stipulated, shall
be provided by Contractor at its expense.
DEFECTIVE MATERIALS
All materials not conforming to the requirements of these Specifications shall be
considered as defective and all such materials, whether in place or not, will be
rejected and shall be removed immediately from the right-of-way unless otherwise
permitted by the Engineer. No material that has been rejected - the defects on
which have been corrected or removed - shall be used until the Engineer’s written
approval has been given.
FAILURE TO REMOVE DEFECTIVE MATERIALS
Should Contractor fail or refuse to remove and renew any defective materials within
the time indicated in writing, the Engineer shall have the authority to cause the
unacceptable or defective materials to be removed and renewed at Contractor's
expense. Any expense incurred by the City in making these removals or renewals,
which Contractor has failed or refused to make, shall be paid for out of any monies
due or which may become due Contractor under this Contract, or may be charged
against the "Contract Bond" deposited.
SECTION VI - LEGAL RELATIONS AND RESPONSIBILITY TO PUBLIC
LAWS TO BE OBSERVED
Contractor shall observe and comply with all laws, ordinances, regulations and
decrees which may, at any time or in any manner, affect the equipment or materials
used at the Project, the conduct of the Work or those employed to complete the
Work. No plea of misunderstanding will be considered on account of the ignorance
thereof.
Contractor further agrees that in connection with the employment and hiring of the
labor necessary for the performance of the Work, or any subcontract hereunder,
Contractor will not discriminate against any person or persons contrary to the
provisions of Minnesota Statutes 181.9, which is hereby incorporated by reference.
GC - 14
Contractor and Contractor’s Surety shall, indemnify and save harmless the City and
all of its officers, agents and servants against any claim or liability arising from or
based on the violation of any law, ordinance, regulation or decree, whether by itself
or its employees.
If Contractor shall discover any provisions in the Plans, Contract, or these
Specifications or any direction of the Engineer or Inspector which is contrary to or
inconsistent with any such law, ordinance, regulation or decree, Contractor shall
immediately report its inconsistency to the Engineer in writing.
PERMITS AND LICENSES
Contractor shall procure all permits and licenses as required in the Contract
documents, pay all charges and fees and give all notices necessary and incidental to
the due and lawful prosecution of the Work.
PATENTED DEVICES, MATERIALS AND PROCESSES
If the Contract requires, or Contractor desires the use of any design, device, material
or process covered by letter, patent or copyright, trademark or trade name,
Contractor shall provide for such use by suitable legal agreement with the patentee
or owner allowing use of such design, devise, material or process in the Work. A
copy of said agreement shall be filed with the City. If no such agreement is made or
filed as noted, Contractor and Contractor’s Surety shall indemnify and save
harmless the City from any and all claims for infringement by reason of the use of
any such patented design, device, material or process, or any trademark or trade
name or copyright in connection with the Work agreed to be performed under the
Contract, and shall indemnify the City for any costs, expenses and damages which it
may be obliged to pay, including costs, expense and attorneys’ fees incident to
litigation by reason of any such infringement at any time during the prosecution or
after the completion of the Work.
SANITARY PROVISIONS
Contractor shall observe and comply with all laws, rules and regulations of the State
and Local Health Authorities and shall take such precautions as are necessary to
avoid creating unsanitary conditions.
Contractor shall provide and maintain suitable sanitary conveniences for the use of
all persons employed on the Project. Such facilities shall be properly screened from
public observation, in sufficient numbers, in such manner and at such points as shall
be approved by the Engineer. Contractor shall rigorously prohibit committance of
nuisances within, on or about the Work. Any employee found violating these
provisions shall be discharged and not again employed on the Work without the
written consent of the Engineer. Contractor shall supply sufficient drinking water to
all of the work force employed, but only from such sources as shall be approved by
GC - 15
the Engineer. Contractor shall also obey and enforce such other sanitary
regulations and orders and shall take such precautions against infectious disease as
may be deemed necessary by the Engineer.
PUBLIC CONVENIENCE AND SAFETY, BARRICADES, LIGHTS AND WARNING
SIGNALS
Where the Work is carried on in or adjacent to any street, alley or public place,
Contractor shall, at Contractor’s own cost and expense, furnish and erect such
barricades, fences, lights and danger signals, and shall take such other
precautionary measures for the protection of persons and property and of the Work
as is necessary or required by the Contract Documents. Excavations in or adjacent
to public streets or alley in which water stands more than one (1) foot deep or where
banks of the excavation are subject to collapse or cave-in shall be securely
barricaded with snow fence so as to prevent access by children and adults during
the period when work is not being carried on at the site of excavation. Barricades
shall be painted in a color and reflectorized in accordance with the provisions of the
most current version of the Minnesota Manual of Uniform Traffic Control Devices
(“MMUTCD”).
From sunset to sunrise, Contractor shall furnish and maintain at least two (2)
flashing lights at each barricade. A sufficient number of barricades shall be erected
to keep vehicles from being driven on or into any of the Work and to warn
pedestrians and children of the existence of the excavation at all open points. When
a detour is necessary because a street is blocked by the Work, the Engineer shall
designate its route and Contractor shall furnish and post detour signs at places
designated approved by the Engineer. All signs shall be in accordance with the
most current version of the MMUTCD and appendices.
Contractor shall be responsible for all damage to the Work due to failure of
barricades, signs, and lights to protect it, and whenever evidence of such damage is
found, the Engineer may order the damaged portion immediately removed and
replaced by Contractor at Contractor’s expense. Contractor's responsibility for the
maintenance of barricades, signs and lights, and for providing the watchmen, shall
not cease until the Project has been accepted by the City.
MAINTENANCE OF DRAINAGE AND ACCESS TO MUNICIPAL AND PRIVATE
UTILITIES
On all Work, Contractor shall provide and maintain free access to gas valves,
manholes and similar facilities. Contractor shall also provide and maintain free
access to all fire hydrants, gate valves, manholes, and appurtenant equipment of the
City’s water distribution and sanitary sewer systems.
Contractor shall provide for the flow of all water courses, storm sewers and storm
drains, and shall keep all gutters and waterways open or make other provisions for
the free removal of storm water. Contractor shall be liable for any damages or costs
GC - 16
incurred by the City due to flood conditions, or backing up of sanitary or storm
sewers or storm drains caused by the Work. Contractor also agrees to indemnify the
City and its agents and employees against claims relating to or arising from any
such backups or flooding.
SITES TO BE KEPT CLEAN
Contractor shall clean and keep clean from waste materials or refuse resulting from
its operations, the streets, the Work and public property occupied by Contractor.
Equipment not usable on the Work shall be promptly removed and the adjacent
premises maintained in a neat and orderly condition at all times. Advertising signs in

USE OF EXPLOSIVES
If it is necessary to use explosives in the performance of the Work, Contractor shall
take out permits and comply with all laws, ordinances and regulations governing
same. Contractor shall fully protect all completed Work as well as all overhead,
surfaces or underground structures and shall be liable for any damage done to the
Work or other structures on public or private property and injuries sustained by
persons by reason of the use of explosives in Contractor’s operations. Explosives
shall be handled, used and fired only by experienced personnel. All firing shall be
done by electricity. All explosive supplies shall be safely stored and protected in an
approved manner. All such storage places shall be marked clearly, "DANGEROUS
– EXPLOSIVES". Caps or other exploders shall not be stored at the place where
dynamite or other explosives are stored.
PROTECTION AND RESTORATION OF PROPERTY
Where the Work passes over or through private property, the City shall secure a
license, right of entry, right-of-way agreement or easement. Contractor shall not
receive any extra compensation or be entitled to any extras because of delay on the
part of the City in obtaining right-of-way or easement access. Contractor shall not
enter upon private property for any purpose without obtaining written permission
from the property owner. Contractor shall, at Contractor’s own expense, protect and
restore any public or private property damaged or injured in consequence of any act
or omission on Contractor’s part or on the part of Contractor’s employees or
subcontractors, to a condition equal to or better than that existing before such
damage or injury occurred. If Contractor neglects to restore or make good such
damage or injury, the Engineer may, upon forty-eight (48) hours’ notice, proceed to
GC - 17
restore or make good such damage or injury and to order the cost thereof deducted
from any monies that are or may come due to Contractor.
Contractor shall restore at Contractor’s own expense all parks, streets, alleys, roads,
or public highways, and the public structures and improvements which may occupy
such parks, streets, roads, alleys, or public highways, including but not limited to
water mains, water connections and appurtenances, sewer, manholes, catch basins,
and sewer connections, ornamental light poles, and cables. All persons, firms,
trustees, and corporations having buildings, structures, works, conduits, mains,
pipes, tracks, poles, wires, cables, ducts, or other physical structures and
improvements in, over, or under the public lands, streets, roads, alleys, or highways,
shall be notified by the City to shift, adjust, accommodate or remove any such
interfering works so as to comply reasonably with the requirements of construction.
Thereafter, Contractor shall be responsible for all just and proper claims for
damages caused to or on account of such interference or removal, and shall at
Contractor’s own cost and expense reimburse such persons, firms, trustees and
corporations all just and proper claim for such removal and replacement or repair.
Contractor shall include the cost of such interference, removal and replacement in
the various affected unit and lump sum prices, and no separate payment will be
made to Contractor for any cost involved by reason of any causes or situations
arising from such interference, removal or replacement.
Land monuments shall not be moved or otherwise disturbed except as may be
directed by the Engineer.
EXISTING SURFACE, OVERHEAD AND UNDERGROUND STRUCTURES
Prior to construction, Contractor shall obtain field locations or other assistance as
may be required to determine the existence and location of gas mains and other
private utilities, as well as public utilities of the City, County or State, which may be
underground or overhead within street and highway rights-of-way or within
easements and which may be interfered with by the Work.
Existing underground, surface or overhead structures are not necessarily shown on
the Plans, and those shown are only correct to the level of accuracy permitted by the
locations both from field located and record drawings, established by the utility
owners. The City does not assume any responsibility for the accuracy of the
disclosed locations. Contractor shall be responsible for all verifying all utility location
by contacting Gopher State One-Call (651.454.0002) prior to beginning the Work.
Contractor shall also make such investigations as are necessary to determine the
extent to which existing structures may interfere with the Work prior to submitting its
Proposal. The sizes, locations and depths of such structures as are shown on the
Plans and profiles are only approximate and Contractor shall satisfy itself as to the
accuracy of the information given.
GC - 18
Contractor shall not claim or be entitled to receive compensation for any damages
sustained by reason of the inaccuracy of the omission of any of the information given
on the drawings relative to the surface, overhead or underground structures or by
reason of Contractor’s failure to properly protect and maintain such structures.
Contractor shall exercise extreme care in crossing, or working adjacent to, all utilities
and shall be responsible to protect and maintain their operation during the Work.
Contractor shall restore, at its expense, any public structures such as, including but
not limited to, water mains, water connections, and appurtenances, sewers,
manholes, catch basins, culverts, and sewer connections which are damaged or
injured in any way by Contractor’s acts or the acts of its employees, agents or
subcontractors.
Contractor shall indemnify and save harmless the City from any suit, claim, demand
or expense, including attorneys’ fees and costs, brought for or on account of any
damage, maintenance, removal, replacement, or relocation of mains, conduits,
pipes, poles, wires, cables or other structures of private utility firms or corporations
whether underground or overhead, that may be caused or required by Contractor
during the Work. However, in cases involving an overhead or underground privately
owned utility installed and located in accordance with a permit issued by the City, if,
in the opinion of the Engineer, the relocation of said utility is required to facilitate the
Work, the City shall provide for such relocation, to the extent allowed under the
permit or applicable law.
MAINTENANCE OF SERVICE IN EXISTING STRUCTURES
All existing overhead, surface or sub-surface structures, together with all
appurtenances and service connections except those otherwise provided for herein,
encountered or affected in any way during Work shall be maintained in service at all
times unless other arrangements satisfactory to the agencies responsible for such
utility are made. The cost of this work shall be included in the price paid under the
items applicable thereto and there shall be no separate payment for it.
RAILWAY AND HIGHWAY CROSSINGS
Where the Work encroaches upon any right-of-way of any railway, State or County
Highway, the City shall make application for the necessary easement or permit for
the Work. Where railway tracks or highways are to be crossed, Contractor shall
observe all regulations and instructions of the railway company and Highway
Department and other applicable federal, state or local regulations as to methods of
doing the Work, or precautions for safety of property and the public. Contractor will
not be paid compensation for such railway or highway crossing applications or
regulations unless otherwise provided for in the Proposal or other Contract
Documents.

the City and its agents and employees from and against claims, damages, losses,
and expenses, including but not limited to attorneys’ fees, arising out of or resulting
from performance of the Work, provided that such claim, damage, loss, or expense

destruction of tangible property, but only to the extent caused by the negligent acts
or omissions of Contractor, a Subcontractor, anyone directly or indirectly employed
by them, or anyone for whose acts they may be liable, regardless of whether or not
such claim, damage, loss, or expense is caused in part by a party indemnified

person described in this Section or any other obligations of indemnity under the
Contract Documents.
In claims against any person or entity indemnified under this Section by an
employee of Contractor, a Subcontractor, anyone directly or indirectly employed by

workers’ compensation acts, disability benefit acts, or other employee benefit acts.
CONTRACTOR'S RESPONSIBILITY FOR WORK

SECTION VII - PROSECUTION AND PROGRESS
SUBLETTING OR ASSIGNMENT OF CONTRACT
Contractor shall not sublet, sell, transfer, assign or otherwise dispose of the Contract
or any portion thereof, or of the Work, or of Contractor’s right, title or interest therein,
to any person, firm or corporation without the written consent of the City and
Contractor's Surety, and such consent shall not relieve Contractor in any way of full
responsibility for the performance of this Contract.
Contractor shall include a list of subcontractors with the Proposal. The City reserves
the right to reject any or all of the subcontractors.
PROSECUTION OF WORK
All dealings of the City will be with Contractor. No Work shall be started until the
Contract has been executed and written notice to proceed has been given to
Contractor.
Definite notice of intention to start the Work shall be given to the City at least five (5)
days in advance of beginning the Work. Such starting time shall be within ten (10)
calendar days after the date of receipt by Contractor of written notice to proceed.
The official starting time shall be taken as the date on which Contractor is notified in
writing by the Engineer that Contractor has fulfilled all preliminary requirements of
GC - 23
the City. The official Contract Time shall be in accordance with the Special
Conditions. Should the prosecution of the Work be discontinued temporarily by
Contractor for any reason, Contractor shall notify the Engineer at least twenty-four
(24) hours before again resuming operations and shall not resume operations until it
receives written approval from the Engineer.
Unless otherwise provided for elsewhere in these Specifications, Contractor shall
notify the City of the location at which Contractor intends to begin operations. The
Engineer shall have the right to change the point of beginning or the points of
operation of Contractor's work force.
The Work shall be prosecuted in such manner as to ensure its completion within the
Contract Time. In case of failure to prosecute the Work in such a manner as to
ensure its completion within the Contract Time, the Engineer shall have the right to
require Contractor to place in operation such additional force and equipment as are
deemed necessary by the Engineer.
LIMITATIONS OF OPERATIONS
In case of a dispute arising between two or more Contractors engaged on the same
work as to the respective rights or each under these Specifications, the Engineer
shall determine the matters at issue and shall define the respective rights of the
various interests involved in order to secure the completion of all parts of the Work in
harmony and with satisfactory results. Any such decisions by the Engineer shall be
final and binding on all parties and shall not in any way give rise to or provide a basis
for a claim for extra compensation by any of the parties.
CHARACTER OF WORKMEN AND EQUIPMENT
Contractor shall employ such superintendents, foremen and workmen as are careful
and competent, and the Engineer may demand in writing the dismissal of any person
or persons employed by Contractor in, about or upon the Work, who engages in
misconduct, or who is incompetent or negligent or refuses to comply with the
direction given. Any such person or persons shall not be employed again at the
Project without the written consent of the Engineer. Should Contractor continue to
employ such person or persons at the Project, the City may withhold all payments
which are or may become due, or the Engineer may suspend the Work until the
offending persons are dismissed. Contractor shall not employ any minors, as
defined by the Minnesota Workmen's Compensation Act, on the Project.
Contractor shall keep on the Project, during its progress, a competent
superintendent and any necessary assistants, all satisfactory to the Engineer. The
Superintendent shall meet all requirements contained in the Contract Documents,
including but not limited to those enumerated in Section 10 of the Special
Conditions, and shall not be changed except with the consent of the Engineer,
unless the superintendent proves unsatisfactory to Contractor and ceases to be in
Contractor’s employ. The superintendent shall represent Contractor in all matters
GC - 24
and have the authority to obtain equipment and manpower as needed to complete
the Work. All directions given to the superintendent shall be as binding as if they
were given to Contractor.
All machinery and equipment owned or controlled by Contractor which is proposed
to be used by Contractor on the Work shall be of sufficient size and in such
mechanical condition as to meet with the requirements of the Work and to produce a
satisfactory quality of work.
When so ordered by the Engineer, in writing, unsatisfactory equipment shall be
removed and replaced with equipment which will satisfactorily perform the Work. No
change in the machinery and equipment employed on the Project that has the effect
of decreasing its capacity shall be made except by written permission of the
Engineer.
The measure of the capacity of machinery and equipment shall be its actual
performance of the Work. Failure of Contractor to provide adequate equipment may
result in the annulment of the Contract as hereinafter provided.
CONTRACTOR'S RIGHT TO REQUEST CHANGES
If Contractor discovers, prior to or during construction anything in the Plans or
Specifications or in the supplementary directions issued by the Engineer which, in
the opinion of Contractor, appears to be faulty engineering or design, Contractor
shall immediately advise the Engineer in writing of Contractor’s concerns. If no
objection is raised by Contractor under the provisions of this paragraph, Contractor
waives any right to contest the provisions of the Contract on the basis of faulty
engineering or design.
TEMPORARY SUSPENSION OF WORK
The Engineer shall have the authority to suspend the Work, wholly or in part, for
such a period or periods as the Engineer may deem necessary due to conditions
considered unfavorable for the suitable prosecution of the Work, or for such time as
is necessary due to failure on the part of Contractor to carry out orders or perform
any or all provisions of the Contract. If the Engineer directs Contractor in writing to
suspend the Work, Contractor shall store all materials and equipment in such a way
as to not obstruct or impede public travel or work on adjacent contracts. Contractor
shall not suspend the Work without written authority from the Engineer.
SUBSTANTIAL COMPLETION
When Contractor considers that the Work, or a portion thereof which the City agrees
to accept separately, is substantially complete, Contractor shall prepare and submit
to the Engineer a comprehensive list of items to be completed or corrected prior to
final payment. Failure to include an item on such list does not alter the responsibility
of Contractor to complete all Work in accordance with the Contract Documents.
GC - 25
Upon receipt of Contractor’s list, the Engineer or the Inspector shall inspect the Work
to determine whether it is substantially complete. If the inspection discloses any
item, whether or not included on Contractor’s list, which is not sufficiently complete
in accordance with the Contract Documents so that the City can occupy or utilize the
Work or designated portion thereof for its intended use, Contractor shall, before
issuance of the Certificate of Substantial Completion, complete or correct such item.
In such case, Contractor shall then submit a request for another inspection by the
Engineer to determine Substantial Completion.
When the Work or designated portion thereof is substantially complete as
determined by the Engineer, the Engineer shall prepare a Certificate of Substantial
Completion that shall establish the date of Substantial Completion; establish
responsibilities of the City and Contractor for security, maintenance, damage to the
Work and insurance; and fix the time within which Contractor shall finish all items on
the list accompanying the Certificate. Warranties required by the Contract
Documents shall commence on the date of Substantial Completion of the Work or
designated portion thereof unless otherwise provided in the Certificate of Substantial
Completion.
The Certificate of Substantial Completion shall be submitted to the City and
Contractor for their written acceptance of responsibilities assigned to them in the
Certificate. Upon such acceptance, and consent of surety if any, the City shall make
payment of retainage applying to the Work or designated portion thereof. Such
payment shall be adjusted for Work that is incomplete or not in accordance with the
requirements of the Contract Documents.
DETERMINATION AND EXTENSION OF CONTRACT TIME FOR COMPLETION
Contractor shall perform fully, entirely, and in an acceptable manner, the Work
contracted for within the time stated in the Contract.
If Contractor finds that it will be impossible to complete the Work on or before the
Contract Time, Contractor shall request an extension of the Contract Time as set
forth in Section 4 of the Special Conditions.
In case such extension is not granted, the right to proceed with the Work may be
considered as forfeited as of the Contract Time, including all agreed upon
adjustments, and the City, without violating the Contract, may proceed immediately
to take over the Work, materials and equipment and make final settlement of costs
incurred as provided for in Paragraph 7 below, except that it shall not be necessary
to give Contractor written ten (10) days’ notice for such forfeiture.
FAILURE TO COMPLETE WORK ON TIME
Should Contractor fail to complete the Work on or before the Contract Time, taking
into consideration all agreed upon extensions, the City may permit Contractor to
GC - 26
proceed and there shall be deducted from any monies due or that may become due
Contractor the amount agreed upon as liquidated damages under section 4 the
Special Conditions of the Agreement. Liquidated damages shall continue to accrue
until the unfinished Work is completed whether Contractor finishes the Work or the
Work is finished by an alternate contractor.
Permitting Contractor to continue and finish the Work or any part of it after the
Contract Time, or after the date to which the Contract Time may have been
extended, shall in no way operate as a waiver on the part of the City of any of its
rights. Neither by the taking over of the Work by the City, nor by the annulment of
the Contract, shall the City forfeit the right to recover liquidated damages from
Contractor or Contractor’s Surety for failure to complete the Contract.
RIGHT OF THE CITY TO DECLARE CONTRACTOR IN DEFAULT
In addition to those instances specifically referred to in the Contract Documents, the
City shall have the right to declare Contractor in default of the whole or any part of
the Work if:
A. Contractor becomes insolvent;
B. Contractor makes an assignment for the benefit of creditors pursuant to the
Statutes of the State of Minnesota;
C. A voluntary or involuntary petition in bankruptcy be filed by or against Contractor;
D. Contractor fails to commence work when notified to do so by the Engineer;
E. Contractor shall abandon the Work;
F. Contractor shall refuse to proceed with the Work when and as directed by the
Engineer;
G. Contractor shall, without just cause, reduce its working force to a number which,
if maintained would be insufficient, in the opinion of the Engineer, to complete the
Work in accordance with the approved progress schedule, and shall fail or refuse
to sufficiently increase such working force when ordered to so by the Engineer;
H. Contractor shall sublet, assign, transfer, convey or otherwise dispose of this
Contract other than as herein specified;
I. A receiver or receivers are appointed to take charge of Contractor's property or
affairs;
J. The Engineer shall be of the opinion that Contractor is or has been knowingly,
willfully or in bad faith, violating any of the provisions of this Contract;
K. The Engineer shall be of the opinion that Contractor is or has been
unnecessarily, unreasonable or willfully delaying the performance and completion
GC - 27
of the Work, or the award of a necessary subcontract or the placing of necessary
material or equipment orders;
L. The Engineer shall be of the opinion that the Work cannot be completed within
the Contract Time, taking into consideration all agreed upon amendments to the
Contract Time; provided, however, that the impossibility of timely completion is,
in the Engineer's opinion, attributable to conditions within Contractor's control;
M. The Engineer shall be of the opinion that Contractor is not or has not been
executing the Contract in good faith and in accordance with its terms; or
N. The Work is not completed within t within the Contract Time, taking into
consideration all agreed upon amendments to the Contract Time.
Before the City shall exercise its right to declare Contractor in default by reason of
the conditions set forth in items numbered 1, 4-7, 10-13, or 14, it shall give
Contractor an opportunity to be heard, on two days’ notice, at which hearing
Contractor may have a stenographer present; provided, however, that a copy of
such stenographic notes, if any, shall be furnished to the City.
The right to declare in default for any of the grounds specified or referred to above
shall be exercised by sending Contractor a notice, signed by the Engineer, setting
forth the grounds upon which such default is declared. Upon receipt of such notice,
Contractor shall immediately discontinue all further operations under this Contract
and shall immediately quit the site, leaving untouched all plant, materials,
equipment, tools and supplies then on the site.
COMPLETION OF THE WORK AFTER DEFAULT
The City, after declaring Contractor in default, may then have the Work completed
by such means and in such manner, by contract with or without public letting or
otherwise, as it may deem advisable, utilizing for such purpose such of Contractor's
plant, materials, equipment, tools, and supplies remaining on the site, and also such
subcontractors as it may deem advisable.
After such completion, the Engineer shall make a certificate stating the expense
incurred in such completion, which shall include the cost of re-letting and also the
total amount of liquidated damages (at the rate provided for in the Specifications)
from the date when the Work should have been completed by Contractor in
accordance with the Contract Documents to the date of actual completion of the
Work. Such certificate shall be binding and conclusive upon Contractor in
accordance with the terms hereof to the date of actual completion of the Work. Such
certificate shall be binding and conclusive upon Contractor, Contractor’s Sureties,
and any person claiming under Contractor, as to the amount thereof.
The expense of such completion, as so certified by the Engineer shall be charged
against and deducted out of such monies as would have been payable to Contractor
GC - 28
if it had completed the Work; the balance of such monies, if any, subject to the other
provisions of this Contract, to be paid to Contractor without interest after such
completion. Should the expense of such completion exceed the total sum which
would have been payable under this Contract if the same had been completed by
Contractor, any such excess shall be paid by Contractor to the City upon demand. If
Contractor fails to pay the City promptly for such excess costs, the City may at its
discretion submit a claim to Contractor’s Surety for such reimbursements.
PARTIAL DEFAULT
In case the City shall declare Contractor in default as to a part of the Work only,
Contractor shall discontinue such part, shall continue performing the remainder of
the Work in strict conformity with the terms of the Contract, and shall in no way
hinder or interfere with any other contractors or persons whom the City may engage
to complete the Work as to which Contractor was declared in default.
The provisions of the clauses herein relating to declaring Contractor in default as to
the entire Work shall be equally applicable to a declaration of partial default, except
that the City shall be entitled to utilize for completion of the Work as to which
Contractor was declared in default only such plant, materials, equipment, tools and
supplies as had been previously used by Contractor on such part.
TERMINATION OF CONTRACTOR'S RESPONSIBILITY
Except as otherwise provided for in these Specifications and in Contractor’s bond,
Contractor’s responsibility for all Work and materials under this Contract shall
continue until the expiration date of the warranty. The warranty shall commence on
the date of Final Completion of the Work.
SECTION VIII - MEASUREMENT AND PAYMENT
MEASUREMENT OF QUANTITIES
Measurement of all Work acceptably completed will be made in accordance with the
system in which the Contract is let, either U.S. Standard or International System
(metric). Such measurements will be used as a basis for the computation of the
quantities of Work performed. Quantities designated to be measured by linear units
will be taken horizontally. Where Work is to be paid for by units of length, area,
volume or mass, only the net amount of Work actually performed, as it shall appear
in the finished Work and measured as hereinafter specified shall be paid for, local
customs to the contrary notwithstanding. Calculation of area quantities where the
computation of the areas by geometric methods would be comparatively laborious, it
is stipulated and agreed that the City’s computer aided drafting system shall be used
as the method of measurement.
GC - 29
SCOPE OF PAYMENT
Contractor shall receive and accept the compensation as herein provided, in full
payment for furnishing all materials, labor, tools, equipment, royalties, fees,
insurance, permits, bonds, etc., and for performing all Work contemplated and
embraced under the Contract, also for all loss or damage arising out of the nature of
the Work, or from the action of the elements, the expiration of the warranty to the
City, and for all risks connected with the prosecution of the Work, also for all
expenses incurred by, or in consequence of the suspension or discontinuance of
said prosecution of the Work as herein specified, and for completing all of the Work
embraced in the Contract.
WORK COVERED BY CONTRACT PRICE
Contractor shall, under Contractor’s contract unit prices, furnish and pay for, all
material and incidental work, furnish all accessories, and do everything which may
be necessary to carry out the Contract in good faith, which contemplates everything

workmanship.
BASIS OF PAYMENT
Where Work is to be paid by linear, area, volume, mass, or by each individual units
Contractor’s cost for all materials, labor, tools and equipment required to complete
the Work, notwithstanding that while the Work may not be fully shown on the
drawings, it may be described in the Specifications and vice-versa.
PAYMENTS FOR INCREASED OR DECREASED QUANTITIES
Whenever the quantity of any item of Work as given in the Proposal shall be
increased or decreased, payment for such item of Work will be made on the basis of
the actual quantity completed at the unit price for such item named in the Proposal,
except as otherwise provided in Section III - Paragraph 2 of these General
Conditions, and in the detail Specifications for each class of Work.
PAYMENT FOR SURPLUS MATERIALS
Payment for materials that have been ordered in furtherance of the Work, but that
are not to be used because (1) of cancellation of the Contract or a portion thereof;
(2) of an order to terminate the Work before completion of the entire unit; or (3) the
quantity ordered by the Engineer was in excess of the quantity needed, will be made
in accordance with this section, unless Contractor or one of Contractor’s suppliers
elects to take possession of the surplus material without expense to the City.
Payment for surplus materials that have been purchased and shipped or delivered to
the Project will be made at the Contract bid price when the pay item covers the
furnishing and delivering of the material only.
GC - 30
When the Contract bid price covers the furnishing and placing of the material, the
City will take possession of the surplus materials that have been purchased and
shipped or delivered to the Project, or will order the material returned to the supplier
for credit and will pay the Contractor the actual purchase price of the material plus
transportation costs, to which will be added fifteen percent (15%) of the total thereof,
and from which will be deducted any credits received by the Contractor for materials
returned.
Materials that have been ordered but have not been consigned for shipment shall be
paid for upon delivery the same as materials in transit or delivered only when the
supplier is unwilling to cancel or modify the order such as in the case of materials
requiring special manufacture, fabrication, or processing so as to be unsuitable for
general use.
In no case shall payment for surplus materials exceed the Contract Price for the
materials complete in place. Contractor shall furnish invoices or an affidavit showing
the purchase price and transportation charges on materials to be taken over by the
City.
Surplus materials that are taken over by the City shall be delivered to the storage
sites designated by the Engineer.
Except as above provided, no payment shall be made to Contractor for any
materials that are not incorporated in the Work. Materials shall be ordered in the
quantities needed unless a specific quantity is to be furnished by direct order of the
Engineer.

PAYMENT FOR UNCLASSIFIED AND FORCE ACCOUNT WORK
Unclassified Work authorized by the Engineer, will be paid for at a unit price, lump
sum or on a Force Account basis. All Force Account Work shall be paid for in the
following manner:
A. For all labor and foremen in the direct charge of the specific Work, Contractor will
receive the actual wages paid for each and every hour that said labor and
foreman are actually engaged in such Work, plus the cost of bond, insurance and
taxes, to which cost shall be added twenty (20) percent of the sum thereof. No
charge shall be made by Contractor for organization or overhead expense.
B. For all materials used, Contractor will receive the actual cost of such materials
including freight charges as shown by original receipted bills, to which cost shall
be added ten (10) percent of the sum thereof. Where materials are specifically
purchased for use on Unclassified Work but are taken from Contractor's stock,
Contractor shall submit an affidavit of the quantity, price and freight on such
materials in lieu of original bills and invoices. This affidavit shall be approved by
the Engineer.
C. For any machinery, trucks or equipment, including fuel and lubricants, which it
may be deemed necessary or desirable to use, Contractor will receive a
reasonable rental price, to be agreed upon in writing before such Work is begun,
for each and every hour that said machinery, trucks and equipment are in use on
such Work, and to which sum no percentage will be added. Such rental price
shall not exceed the rates established by the A.G.C. for this district.
The compensation as herein provided shall be received by Contractor as payment in
full for Unclassified Work done by Force Account and said twenty (20) percent for
labor and said ten (10) percent for materials shall be agreed to cover profit,
superintendence, general expense, overhead, and the use of small tools and
equipment for which no rental is allowed.
Contractor or Contractor’s representative and the Engineer or the Engineer’s
representative shall compare records of Force Account Work at the end of each day.
Copies of these records shall be made in triplicate on Force Account forms, provided
for this purpose by the Engineer and signed by both parties. To all such claims for
Force Account Work, Contractor shall attach receipted bills for, or affidavit of,
materials used and freight receipts covering freight on such materials used, and said
claims shall be presented to the Engineer for payment not later than the twentieth
(20th) day of the month following that in which the Work was actually performed and
shall include all labor charges and material charges insofar as they can be verified.
Should Contractor refuse or fail to prosecute such Unclassified Work as directed, or
to submit this claim as required, the City may withhold payment of all current
GC - 33
estimates until Contractor's refusal or failure is eliminated, or, after giving Contractor
due notice, the City may make payment for said Work on a basis of a reasonable
estimate of the value of the Work performed.
PARTIAL PAYMENTS
Unless payments are withheld by the City for reasons herein before stated, payment
will be made at least once a month on a basis of ninety-five (95) percent of the Work
done, provided that the Work is progressing to the satisfaction of the Engineer;
provided further, however, that when ninety-five (95) percent or more of the Work is
completed, the City, in its sole discretion, may determine that something less than
five (5) percent need be retained to protect the City's interest in satisfactory
completion of the Contract.
Monthly estimates may include the value of acceptable materials required for the
Work, which have been delivered to the Project, and for which acceptable provisions
have been made for the preservation and storage. From the total value of the
materials so reported, five (5) percent shall be retained. Such material, when so
paid for by the City, shall become the property of the City and in the event of default
on the part of Contractor, the City may use or cause to be used such materials in the
construction of the Work provided for in the Contract. The amount thus paid by the
City for materials shall go to reduce estimates due Contractor as the materials are
used in the Work.
Minnesota Statutes, Sections 337.10, subd. 3 and 471.425, subd. 4a, requires that
Contractor pay any subcontractors within ten (10) days after receipt of payment from
the City for undisputed services provided by the subcontractor. Contractor shall
provide proof to the City of payment to subcontractors in the form of check copies or
receipts. If Contractor fails to make payments to subcontractors for undisputed
Work, Contractor shall pay interest of one and one-half percent (1-1/2%) per month
of any amounts not paid on time to subcontractors, with a minimum monthly interest
penalty payment of ten dollars ($10).
No release of any retained percentage will be made without the written approval of
the Surety or Sureties, which approval shall be obtained by Contractor. Any such
release may be optional with the City.
FINAL PAYMENT
Upon receipt of Contractor’s notice that the Work is ready for final inspection and
acceptance, the Engineer shall promptly make such inspection as provided in
section IV(10) of these General Conditions. When the Engineer finds the Work
acceptable under the Contract Documents and the Contract fully performed, the
Engineer will prepare a final estimate containing complete quantities of each and
every item of Work performed by Contractor, and the value thereof (the “Final Pay
Estimate”). Upon acceptance of the Final Pay Estimate by Contractor, the Engineer
will (i) issue a Certificate of Final Completion; (ii) forward the Certificate of Final
GC - 34
Completion and Final Pay Estimate to the City Finance Director for payment; and (iii)
notify Contractor and Contractor’s Surety or Sureties of the acceptance of the Work.
The date of Final Completion of the Contract shall be the date on the Certificate of
Final Completion and the action of the City by which Contractor is bound and the
Contract concluded shall be evidenced by the Certificate of Final Completion and
Final Payment. All prior certificates or estimates upon which payments may have
been made are merely partial estimates and subject to correction in the final
payment.
CERTIFICATE OF COMPLIANCE OF MINNESOTA WITHHOLDING TAX
Final payment will not be made until Contractor shall have filed with the City
evidence, in the form of an affidavit, lien waiver or such other evidence as may be
required, that all claims against Contractor by reason of the Contract have been fully
paid or satisfactorily secured. In case such evidence is not furnished, the City may
retain out of any amount due said Contractor sums sufficient to cover all lienable
claims unpaid.
Before final payment is made for the Work on this project, Contractor must make a
satisfactory showing that it has complied with the provisions of Minnesota Statutes
Section 290.92 requiring the withholding of State Income Tax for wages paid
employees on this project. Receipt by the City Engineer of a Certificate of
Compliance from the Commissioner of Taxation will satisfy this requirement.
Contractor is advised that before such Certificate can be issued, Contractor must
first place on file with the Commissioner of Taxation an affidavit, in the form of an IC-
134, that Contractor has complied with the provisions of Minnesota Statutes Section
290.92.

Asbestos and PCB Information Sheets
ASBESTOS INFORMATION SHEET
Non-friable asbestos is present in some pipe wrap found on old piping within
CenterPoint Energy Minnegasco’s gas distribution system. This information sheet was
prepared to provide interested parties with facts about asbestos as found in our system.
What is asbestos? Asbestos is a group of silicate minerals formerly added to products
to provide strength or insulating properties. Asbestos handling and disposal is closely
regulated by the MN Pollution Control Agency (MPCA), OSHA, and MN Department of
Health (MDH).
Are there different kinds of asbestos? Asbestos can be placed into two broad
categories, friable and non-friable. Friable asbestos can easily become airborne and is
hazardous to handle. Non-friable asbestos cannot be crumbled to a powder under hand
pressure and is not hazardous if handled correctly.
Where is asbestos found in Minnegasco’s system? Asbestos is no longer present
in any new products used by Minnegasco. However, in the past, asbestos was used to
strengthen pipe wrap, and some of the pipe that is coated with asbestos-containing
wrap remains in service. Asbestos may also be found in some old gaskets used by
Minnegasco. The asbestos present in pipe wrap and gaskets is considered non-friable.
How does Minnegasco comply with asbestos regulations? Before starting a project
that may require handling of pipe, Minnegasco determines if the pipe was installed
during the period when asbestos-containing wrap was used. If there is a potential that
the wrap contains asbestos, a MDH Certified professional collects a sample of the wrap.
The sample is analyzed and if asbestos is detected, certain handling requirements must
be followed. The MPCA allows abandoned pipe with asbestos-containing wrap to be
left in the ground. In fact, in most instances they prefer that it be left undisturbed.
However, if it is necessary to remove the pipe, Minnegasco’s crews and contractors
have been trained in the proper handling and disposal procedures.
What are the health and safety considerations? Non-friable asbestos does not
present a health hazard if handled properly. Only procedures that could cause the
asbestos to become airborne would make non-friable asbestos hazardous. Procedures
to be avoided include cutting, grinding, and otherwise crushing the materials.
Minnegasco crews and contractors have been trained in proper handling of our
asbestos-containing wrap to minimize exposure to themselves or the public.
Who can I contact at Minnegasco if I have more questions about asbestos?

For New Users to QuestCDN vBid™ (On-line Bidding)
Prior to starting use of the QuestCDN vBid™, be sure to set up your company’s On-line Bid ID Code and update
your password to higher security if required. You can do this by logging in at www.questcdn.com and going to the
“My Account” page. If you do not have access to the “My Account” page, please contact the administrator at your
company.
A summary of steps for using www.questcdn.com for submitting electronic bids is as follows:
1. From QuestCDN, download the project documents using the project number referenced (may need to
refresh after download);
2. Click on the “On-line Bid” button to go to Quest vBid™, log into the VirtuBid™ Server with your QuestCDN
User Name and Password (not your On-line Bid ID Code);
3. Fill out the Qualification Information Tab and download the required documents – Save;
4. Upload any required completed documents – Save;
5. Upload Bid Bond – Save;
6. Go to the Bid Worksheet Tab and fill out all required fields or use the export and import to complete the
Bid Worksheet – Save;
7. Download any issued addenda; and
8. When finished with both the Qualification Information and Worksheet Tabs, click Submit – you will need
your company’s On-line Bid ID Code. This is a special passcode (your company digital signature)
required only at bid submittal – it can be added or changed at www.questcdn.com on the “My Account”
page. There is a link to the “My Account” page on the submission screen. (Only the system
administrator’s login to your company account can access the “My Account” functions.)
Bid Openings
The bid date and time on the QuestCDN server screen is the official time of the bid opening. At the time of bid
opening, representatives from the City of Golden Valley will open and review all electronic bids received.
Preliminary Base Bid Results will be shared with all bidders on the project once the Owner has reviewed and
accepted (AS READ) all the electronic bids. Bid results may be viewed at www.questcdn.com. This information
will also be shared via email from QuestCDN.
FAQs
What kind of equipment and software do I need?
It is required to have Internet capabilities on a computer running operating systems required by QuestCDN. A
scanner will be required to electronically submit scanned copies of required documents for bid submission. No
software needs to be downloaded to submit electronic bids.
Do I need special software to download and save documents?
Bid documents are delivered in Adobe PDF (Portable Document Format) (.pdf). No software investment is
required, free PDF reader programs are available. (Sometimes the PDF file will be Zipped; make sure to save to
the ZIP folder and then open and save the PDF files, so you do not miss any project information.)
Why is the Owner accepting only electronic bid submission for their project?
- Electronic bid submission reduces the number of nonconforming bids and math errors commonly seen in
paper bids.
- Bidders now have the option to attend bid openings electronically. It also allows bidders to make changes
closer to bid opening.
- QuestCDN’s on-line bidding tool allows efficient bid submittal from the comfort of your home or office.
- QuestCDN’s on-line bidding tool allows the uploading and submitting of forms and bid worksheet online,
while a bid clock notifies the time left to submit bids.
- All required bid documents are included in submittals, as well as checks and balances to assure Bidder has
submitted all required documents.
What Internet browsers can be used?
Internet browsers, as required by QuestCDN, shall be used; Google Chrome, IE, or Edge are preferred but not
required. Please make sure you have updated your browser to the most current version.
How do I ensure that my bids are secure?
The software program uses an encryption code and other security methods which prohibit anyone, including the
Owner and the service provider from reading your bid. Once the bid opening time is reached, the Owner can read
bids but cannot alter the bids in any way.
Bidders do not have the ability to see other bids until the Owner chooses to share the bids.
The Owner will only share Base Bid and Sections totals with all bidders on the project once they have reviewed all
the electronic bids.
May I make changes to my bid and submit a bid more than once?
Yes. Bidders can withdraw a bid, make changes, and resubmit a bid as many times they wish, until the bid
opening time has occurred.
Will I know if my bid changes are accepted?
Yes. Each time a bid is withdrawn and resubmitted, the bidder will receive an email from QuestCDN confirming
that they have successfully submitted a bid. Your On-line Bidding screen will also indicate that the bid has been
submitted successfully. If you have an error, the bid will not be submitted, and an error message will be at the top
of the On-line Bidding screen.
May I withdraw a bid?
Yes. Bidders may withdraw a bid prior to the bid opening time. If a bidder withdraws a bid prior to the bid opening
time, the Owner will not see the bid.
What occurs when an addendum is posted for the project?
If a bidder already submitted a bid, QuestCDN will withdraw the bid and email the bidder. The bidder will need to
sign into QuestCDN, download the addendum, make changes to the bid if required, and resubmit the bid. If the
bidder has not already submitted a bid, the bidder will need to sign into QuestCDN and download the addendum
prior to submitting a bid.
How do I submit a Bid Bond electronically?
All bids must be accompanied by a Bid Bond as required by the project bid documents. Bid Bonds ensure that
only legitimate bids are submitted. A scanned copy of the Bid Bond must be uploaded prior to submitting a bid.
Who do we contact with questions about QuestCDN?
Contact QuestCDN at 952.233.1632 or info@questcdn.com with questions regarding free membership
registration, downloading, on-line bidding, or working with digital bid documents.
