Bid security in the amount of 5 percent (5%) of the Bid must accompany each Bid in accordance with the Instructions to Bidders. Bidders are required to submit information indicating they have practical experience of the particular construction work bid upon, and that they have the ability and resources to complete the proposed work in a manner satisfactory to the Owner. A contract award will only be made to a bidder meeting the minimum 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.

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 to be performed, and correlated personal observations with requirements of the Contract Documents.

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. 3. BID SECURITY Each bid shall be accompanied by a cash deposit, certified or cashier’s check, or bid bond with a corporate surety in an amount at least equal to five (5) percent of the total amount of the base bid, payable to the City as a guaranty that the Bidder will enter into a contract with the City for the work described in the Proposal, and the amount of the bid security of a successful Bidder shall be forfeited to the City as liquidated damages in the event that such Bidder fails to enter into a contract and furnish Contractor’s bond. 4.

INTERPRETATION OF ESTIMATES The award of the Contract shall be made on the basis of the Engineer’s estimate of quantities as shown in the Proposal, but these quantities are not guaranteed to be accurate and are furnished without any liability on the part of the City. Quantities indicated by the Engineer on drawings or elsewhere are estimated only, and Bidders must rely on their own calculations. 8. DELIVERY OF PROPOSALS Bidders shall submit their Proposal via QuestCDN, if there are any addenda for this project, they must be downloaded in order to submit your electronic bid. This project will be bid using QuestCDN’s on-line bidding tool known as VirtuBid™ (vBid™). Only bids received through vBid™ will be accepted. See the Project Manual Appendix for instructions on the use of this bidding tool. 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.

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.

When using non soluble additives the grout tanks must have mechanical mixing devices to keep the additives in suspension and maintain a uniform solution of grout and additive. 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 1.

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. 82.

It shall be understood by the Bidder that, in the event of annulment of the award, the amount of the Proposal Guarantee deposited with the Proposal shall be retained by the City, not as a penalty, but as liquidated damages to compensate the City for additional costs and expenses. SECTION III - SCOPE OF WORK INTENT OF PLANS AND SPECIFICATIONS The intent of the Plans and Specifications is to prescribe the complete Work or improvement that Contractor undertakes to do. The Plans and Specifications shall be read and interpreted in conjunction with the Contract Documents. Unless otherwise provided, it is understood that Contractor shall furnish all labor, material, equipment, tools, transportation, necessary supplies and incidentals as may reasonably be required to complete the Work in accordance with the Plans, Specifications and other Contract Documents. The approved Plans are on file in the office of the City Clerk, City of Golden Valley, Golden Valley City Hall, 7800 Golden Valley Road, Golden Valley, Minnesota 55427, and show the location, details and dimensions of the Work. Any deviations from the Contract Documents as may be required during construction shall, in all cases, be determined by the Engineer and authorized in writing by the Engineer before such deviations are consummated. The City may attach addenda to these Specifications, to be filed with such Specifications and incorporated as part thereof, at the office of the City Clerk of Golden Valley. Bidders shall be responsible to examine such Specifications as are on file for addenda before submitting Proposals. INCREASED OR DECREASED QUANTITIES OF WORK The Engineer shall have the sole right to increase or decrease any or all of the items specified in the Contract Documents, including the elimination of any one or more GC - 5 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.

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 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 completed, in good working order, of good material, with good and accurate 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. CLAIMS AND PROTESTS A. General A Claim is a demand or assertion by one of the parties seeking, as a matter of right, payment of money, a change in the Contract Time, or other relief with respect to the terms of the Contract. The term “Claim” also includes other disputes and matters in question between the City and Contractor arising out of or relating to the Contract. The responsibility to substantiate Claims shall rest with the party making the Claim. This Section does not require the City to file a Claim in order to impose liquidated damages in accordance with the Contract Documents. B. Time Limit on Claims The City and Contractor shall commence all Claims and causes of action against the other and arising out of or related to the Contract, whether in contract, tort, breach of warranty or otherwise, in accordance with the requirements of this Section and within the period specified by applicable law, but in any case not more than one year GC - 31 after the date of Substantial Completion of the Work. The City and Contractor waive all Claims and causes of action not commenced in accordance with this Section. C. Notice of Claims Claims by either the City or Contractor shall be initiated by notice to the other party and shall be initiated within ten (10) days after occurrence of the event giving rise to such Claim or within ten (10) days after the claimant first recognizes, or reasonably should have recognized, the condition giving rise to the Claim, whichever is later. Any Claim not made within ten (10) days shall be deemed waived. D. Continuing Contract Performance Pending final resolution of a Claim, except as otherwise agreed in writing, Contractor shall proceed diligently with performance of the Contract and the City shall continue to make payments in accordance with the Contract Documents. The Contract Price and Contract Time shall be adjusted in accordance with the resolution of the Claim, subject to the right of either party to proceed in accordance with this section. E. Claims for Additional Cost If Contractor wishes to make a Claim for an increase in the Contract Price, notice as provided in Subsection 1C above shall be given before proceeding to execute the portion of the Work that is the subject of the Claim. Prior notice is not required for Claims relating to an emergency endangering life or property. F. Claims for Additional Time If Contractor wishes to make a Claim for an extension of the Contract Time, Contractor shall request an extension as set forth in Section 4 of the Special Conditions. G. Mediation Claims, disputes, or other matters in controversy arising out of or related to the Contract, except those waived as provided for in the Contract Documents, shall be subject to mediation as a condition precedent to commencement of litigation. The parties shall endeavor to resolve their Claims by mediation which shall be administered by a mediator mutually agreed upon by the parties. A request for mediation shall be made in writing, delivered to the other party to the Contract and shall be completed within ninety (90) days from the date the request for mediation was delivered to the other party. The parties shall share the mediator’s fee and any filing fees equally. The mediation shall be held in Hennepin County, Minnesota, unless another location is mutually agreed upon. Agreements reached in mediation shall be enforceable as settlement agreements in any court having jurisdiction thereof. GC - 32 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.

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?

Sewer/Water Utility - Trace Wire Specification This Standard specification was prepared by Joe Rubbelke (joe.rubbelke@gmail.com), Jeff Dale (jeff.dale@mrwa.com) and Frank Stuemke (frank.stuemke@mrwa.com), and is a work-in-progress, intended for redistribution, modification and immediate use by any municipality (March 2014). The end user must accept all liabilities and hold harmless the contributors of this information. x Service Laterals on public property - Trace wire must terminate at an approved grade level/in- ground trace wire access box, located at the edge of the road right-of-way, and out of the roadway. x Service Laterals on private property - Trace wire must terminate at an approved above-ground trace wire access box, affixed to the building exterior directly above where the utility enters the building, at an elevation not greater than 5 vertical feet above finished grade, or terminate at an approved grade level/in-ground trace wire access box, located within 2 linear feet of the building being served by the utility. x Hydrants – Trace wire must terminate at an approved above-ground trace wire access box, properly affixed to the hydrant grade flange. (affixing with tape or plastic ties shall not be acceptable) x Long-runs, in excess of 500 linear feet without service laterals or hydrants - Trace wire access must be provided utilizing an approved grade level/in-ground trace wire access box, located at the edge of the road right-of-way, and out of the roadway. The grade level/in-ground trace wire access box shall be delineated using a minimum 48” polyethylene marker post, color coded per APWA standard for the specific utility being marked. Grounding x Trace wire must be properly grounded at all dead ends/stubs x Grounding of trace wire shall be achieved by use of a drive-in magnesium grounding anode rod with a minimum of 20ft of #14 red HDPE insulated copper clad steel wire connected to anode (minimum 0.5 lb.) specifically manufactured for this purpose, and buried at the same elevation as the utility. x When grounding the trace wire at dead ends/stubs, the grounding anode shall be installed in a direction 180 degrees opposite of the trace wire, at the maximum possible distance. x When grounding the trace wire in areas where the trace wire is continuous and neither the mainline trace wire or the grounding anode wire will be terminated at/above grade, install grounding anode directly beneath and in-line with the trace wire. Do not coil excess wire from grounding anode. In this installation method, the grounding anode wire shall be trimmed to an appropriate length before connecting to trace wire with a mainline to lateral lug connector. x Where the anode wire will be connected to a trace wire access box, a minimum of 2 ft. of excess/slack wire is required after meeting final elevation. Installation General x Trace wire installation shall be performed in such a manner that allows proper access for connection of line tracing equipment, proper locating of wire without loss or deterioration of low frequency (512Hz) signal for distances in excess of 1,000 linear feet, and without distortion of signal caused by multiple wires being installed in close proximity to one another. x Trace wire systems must be installed as a single continuous wire, except where using approved connectors. No looping or coiling of wire is allowed.

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.
