Where the Contract Documents provide that all or part of the Work is to be Unit Price Work, initially the Contract Price will be deemed to include for all Unit Price Work an amount equal to the sum of the unit price for each separately identified item of Unit Price Work times the estimated quantity of each item as indicated in the Agreement.   B. The estimated quantities of items of Unit Price Work are not guaranteed and are solely for the purpose of comparison of Bids and determining an initial Contract Price. Determinations of the actual quantities and classifications of Unit Price Work performed by Contractor will be made by   00 72 00 - 1 GENERAL CONDITIONS Page 44 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 City subject to the provisions of Paragraph 9.05.   C.

A significant change in the character of work occurs when:   a. the character of work for any Item as altered differs materially in kind or nature from that in the Contract or   b. a Major Item of work varies by more than 25% from the original Contract quantity.   5. When the quantity of work to be done under any Major Item of the Contract is more than 125% of the original quantity stated in the Contract, then either party to the Contract may request an adjustment to the unit price on the portion of the work that is above 125%.   6. When the quantity of work to be done under any Major Item of the Contract is less than 75% of the original quantity stated in the Contract, then either party to the Contract may request an adjustment to the unit price.     00 72 00 - 1 GENERAL CONDITIONS Page 45 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 11.04 Plans Quantity Measurement for Unclassified Excavation or Embankment   A.

If the quantity measured as outlined under “Price and Payment Procedures” varies by more than 25% (or as stipulated under “Price and Payment Procedures” for specific Items) from the total estimated quantity for an individual Item originally shown in the Contract Documents, an adjustment may be made to the quantity of authorized work done for payment purposes. The party to the Contract requesting the adjustment will provide field measurements and calculations showing the final quantity for which payment will be made. Payment for revised quantity will be made at the unit price bid for that Item, except as provided for in Article 10.   C. When quantities are revised by a change in design approved by the City, by Change Order, or to correct an error, or to correct an error on the plans, the plans quantity will be increased or decreased by the amount involved in the change, and the 25% variance will apply to the new plans quantity.   D. If the total Contract quantity multiplied by the unit price bid for an individual Item is less than $250 and the Item is not originally a plans quantity Item, then the Item may be paid as a plans quantity Item if the City and Contractor agree in writing to fix the final quantity as a plans quantity.   E. For callout work or non-site specific Contracts, the plans quantity measurement requirements are not applicable.   ARTICLE 12 – CHANGE OF CONTRACT PRICE; CHANGE OF CONTRACT TIME   12.01 Change of Contract Price   A. The Contract Price may only be changed by a Change Order.   B. The value of any Work covered by a Change Order will be determined as follows:   1. where the Work involved is covered by unit prices contained in the Contract Documents, by application of such unit prices to the quantities of the items involved (subject to the provisions of Paragraph 11.03); or   2. where the Work involved is not covered by unit prices contained in the Contract Documents, by a mutually agreed lump sum or unit price (which may include an allowance for overhead and profit not necessarily in accordance with Paragraph 12.01.C.2), and shall include the cost of any secondary impacts that are foreseeable at the time of pricing the cost of Extra Work; or   3. where the Work involved is not covered by unit prices contained in the Contract Documents   00 72 00 - 1 GENERAL CONDITIONS Page 46 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 and agreement to a lump sum or unit price is not reached under Paragraph 12.01.B.2, on the basis of the Cost of the Work (determined as provided in Paragraph 11.01) plus a Contractor’s fee for overhead and profit (determined as provided in Paragraph 12.01.C).   C.

Such inspections, tests, re-tests, or approvals shall be performed by organizations acceptable to City.   D. City may arrange for the services of an independent testing laboratory (“Testing Lab”) to perform any inspections or tests (“Testing”) for any part of the Work, as determined solely by City.   1. City will coordinate such Testing to the extent possible, with Contractor;   2. Should any Testing under this Section 13.03 D result in a “fail”, “did not pass” or other similar negative result, the Contractor shall be responsible for paying for any and all retests.

Any amounts owed for any retest under this Section 13.03 D shall be paid directly to the Testing Lab by Contractor. City will forward all invoices for retests to Contractor.   4. If Contractor fails to pay the Testing Lab, City will not issue Final Payment until the Testing Lab is paid.   E.

Promptly after receipt of written notice, Contractor shall correct all defective Work pursuant to an acceptable schedule, whether or not fabricated, installed, or completed, or, if the Work has been rejected by City, remove it from the Project and replace it with Work that is not defective. Contractor shall pay all claims, costs, additional testing, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or arbitration or other dispute resolution costs) arising out of or relating to such correction or removal (including but not limited to all costs of repair or replacement of work of others). Failure to require the removal of any defective Work shall not constitute acceptance of such Work.     00 72 00 - 1 GENERAL CONDITIONS Page 50 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 B. When correcting defective Work under the terms of this Paragraph 13.06 or Paragraph 13.07, Contractor shall take no action that would void or otherwise impair City’s special warranty and guarantee, if any, on said Work.   13.07 Correction Period   A. If within two (2) years after the date of Final Acceptance (or such longer period of time as may be prescribed by the terms of any applicable special guarantee required by the Contract Documents), any Work is found to be defective, or if the repair of any damages to the land or areas made available for Contractor’s use by City or permitted by Laws and Regulations as contemplated in Paragraph 6.10.A is found to be defective, Contractor shall promptly, without cost to City and in accordance with City’s written instructions:   1. repair such defective land or areas; or   2. correct such defective Work; or   3. if the defective Work has been rejected by City, remove it from the Project and replace it with Work that is not defective, and   4. satisfactorily correct or repair or remove and replace any damage to other Work, to the work of others or other land or areas resulting therefrom.   B. If Contractor does not promptly comply with the terms of City’s written instructions, or in an emergency where delay would cause serious risk of loss or damage, City may have the defective Work corrected or repaired or may have the rejected Work removed and replaced. All claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or other dispute resolution costs) arising out of or relating to such correction or repair or such removal and replacement (including but not limited to all costs of repair or replacement of work of others) will be paid by Contractor.   C. In special circumstances where a particular item of equipment is placed in continuous service before Final Acceptance of all the Work, the correction period for that item may start to run from an earlier date if so provided in the Contract Documents.   D. Where defective Work (and damage to other Work resulting therefrom) has been corrected or removed and replaced under this Paragraph 13.07, the correction period hereunder with respect to such Work may be required to be extended for an additional period of one year after the end of the initial correction period. City shall provide 30 days written notice to Contractor should such additional warranty coverage be required. Contractor may dispute this requirement by filing a Contract Claim, pursuant to Paragraph 10.06.   E. Contractor’s obligations under this Paragraph 13.07 are in addition to any other obligation or warranty. The provisions of this Paragraph 13.07 shall not be construed as a substitute for, or a waiver of, the provisions of any applicable statute of limitation or repose.     00 72 00 - 1 GENERAL CONDITIONS Page 51 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 13.08 Acceptance of Defective Work   If, instead of requiring correction or removal and replacement of defective Work, City prefers to accept it, City may do so. Contractor shall pay all claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or other dispute resolution costs) attributable to City’s evaluation of and determination to accept such defective Work and for the diminished value of the Work to the extent not otherwise paid by Contractor. If any such acceptance occurs prior to Final Acceptance, a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work, and City shall be entitled to an appropriate decrease in the Contract Price, reflecting the diminished value of Work so accepted.   13.09 City May Correct Defective Work   A. If Contractor fails within a reasonable time after written notice from City to correct defective Work, or to remove and replace rejected Work as required by City in accordance with Paragraph 13.06.A, or if Contractor fails to perform the Work in accordance with the Contract Documents, or if Contractor fails to comply with any other provision of the Contract Documents, City may, after seven (7) days written notice to Contractor, correct, or remedy any such deficiency.   B. In exercising the rights and remedies under this Paragraph 13.09, City shall proceed expeditiously. In connection with such corrective or remedial action, City may exclude Contractor from all or part of the Site, take possession of all or part of the Work and suspend Contractor’s services related thereto, and incorporate in the Work all materials and equipment incorporated in the Work, stored at the Site or for which City has paid Contractor but which are stored elsewhere. Contractor shall allow City, City’s representatives, agents, consultants, employees, and City’s other contractors, access to the Site to enable City to exercise the rights and remedies under this Paragraph.   C. All claims, costs, losses, and damages (including but not limited to all fees and charges of engineers, architects, attorneys, and other professionals and all court or other dispute resolution costs) incurred or sustained by City in exercising the rights and remedies under this Paragraph 13.09 will be charged against Contractor, and a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work; and City shall be entitled to an appropriate decrease in the Contract Price.   D. Contractor shall not be allowed an extension of the Contract Time because of any delay in the performance of the Work attributable to the exercise of City’s rights and remedies under this Paragraph 13.09.   ARTICLE 14 – PAYMENTS TO CONTRACTOR AND COMPLETION   14.01 Schedule of Values   The Schedule of Values for lump sum contracts established as provided in Paragraph 2.07 will serve as the basis for progress payments and will be incorporated into a form of Application for Payment   00 72 00 - 1 GENERAL CONDITIONS Page 52 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 acceptable to City. Progress payments on account of Unit Price Work will be based on the number of units completed.   14.02 Progress Payments   A. Applications for Payments:   1. Contractor is responsible for providing all information as required to become a vendor of the City.   2. At least 20 days before the date established in the General Requirements for each progress payment, Contractor shall submit to City for review an Application for Payment filled out and signed by Contractor covering the Work completed as of the date of the Application and accompanied by such supporting documentation as is required by the Contract Documents.   3. If payment is requested on the basis of materials and equipment not incorporated in the Work but delivered and suitably stored at the Site or at another location agreed to in writing, the Application for Payment shall also be accompanied by a bill of sale, invoice, or other documentation warranting that City has received the materials and equipment free and clear of all Liens and evidence that the materials and equipment are covered by appropriate insurance or other arrangements to protect City’s interest therein, all of which must be satisfactory to City.   4. Beginning with the second Application for Payment, each Application shall include an affidavit of Contractor stating that previous progress payments received on account of the Work have been applied on account to discharge Contractor’s legitimate obligations associated with prior Applications for Payment.   5. The amount of retainage with respect to progress payments will be as stipulated in the Contract Documents.   B. Review of Applications:   1. City will, after receipt of each Application for Payment, either indicate in writing a recommendation of payment or return the Application to Contractor indicating reasons for refusing payment. In the latter case, Contractor may make the necessary corrections and resubmit the Application.   2. City’s processing of any payment requested in an Application for Payment will be based on City’s observations of the executed Work, and on City’s review of the Application for Payment and the accompanying data and schedules, that to the best of City’s knowledge:   a. the Work has progressed to the point indicated;   b. the quality of the Work is generally in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning whole prior to or upon Final Acceptance,   00 72 00 - 1 GENERAL CONDITIONS Page 53 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 the results of any subsequent tests called for in the Contract Documents, a final determination of quantities and classifications for Work performed under Paragraph 9.05, and any other qualifications stated in the recommendation).   3. Processing any such payment will not thereby be deemed to have represented that:   a. inspections made to check the quality or the quantity of the Work as it has been performed have been exhaustive, extended to every aspect of the Work in progress, or involved detailed inspections of the Work beyond the responsibilities specifically assigned to City in the Contract Documents; or   b. there may not be other matters or issues between the parties that might entitle Contractor to be paid additionally by City or entitle City to withhold payment to Contractor, or   c. Contractor has complied with Laws and Regulations applicable to Contractor’s performance of the Work.   4. City may refuse to process the whole or any part of any payment because of subsequently discovered evidence or the results of subsequent inspections or tests, and revise or revoke any such payment previously made, to such extent as may be necessary to protect City from loss because:   a. the Work is defective, or the completed Work has been damaged by the Contractor or his subcontractors, requiring correction or replacement;   b. discrepancies in quantities contained in previous applications for payment;   c. the Contract Price has been reduced by Change Orders;   d. City has been required to correct defective Work or complete Work in accordance with Paragraph 13.09; or   e. City has actual knowledge of the occurrence of any of the events enumerated in Paragraph 15.02.A. C. Retainage:   1. For all contracts, retainage shall be five percent (5%).   D. Liquidated Damages: For each calendar day that any work shall remain uncompleted after the time specified in the Contract Documents, the sum per day specified in the Agreement, will be deducted from the monies due the Contractor, not as a penalty, but as liquidated damages suffered by the City.   E. Payment: Contractor will be paid pursuant to the requirements of this Article 14 and payment will become due in accordance with the Contract Documents.   00 72 00 - 1 GENERAL CONDITIONS Page 54 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018   F. Reduction in Payment: 1. City may refuse to make payment of the amount requested because: a. Claims have been made against City on account of Contractor’s performance or furnishing of the Work; b. Liens have been filed in connection with the Work, except where Contractor has delivered a specific bond satisfactory to City to secure the satisfaction and discharge of such Liens; c. there are other items entitling City to a set-off against the amount recommended; or d. City has actual knowledge of the occurrence of any of the events enumerated in Paragraphs 14.02.B.4.a through 14.02.B.4.e or Paragraph 15.02.A. 2. If City refuses to make payment of the amount requested, City will give Contractor written notice stating the reasons for such action and pay Contractor any amount remaining after deduction of the amount so withheld. City shall pay Contractor the amount so withheld, or any adjustment thereto agreed to by City and Contractor, when Contractor remedies the reasons for such action.     00 72 00 - 1 GENERAL CONDITIONS Page 55 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 14.03 Contractor’s Warranty of Title   Contractor warrants and guarantees that title to all Work, materials, and equipment covered by any Application for Payment, whether incorporated in the Project or not, will pass to City no later than the time of payment free and clear of all Liens.   14.04 Partial Utilization   A. Prior to Final Acceptance of all the Work, City may use or occupy any substantially completed part of the Work which has specifically been identified in the Contract Documents, or which City, determines constitutes a separately functioning and usable part of the Work that can be used by City for its intended purpose without significant interference with Contractor’s performance of the remainder of the Work. City at any time may notify Contractor in writing to permit City to use or occupy any such part of the Work which City determines to be ready for its intended use, subject to the following conditions:   1. Contractor at any time may notify City in writing that Contractor considers any such part of the Work ready for its intended use.   2. Within a reasonable time after notification as enumerated in Paragraph 14.05.A.1, City and Contractor shall make an inspection of that part of the Work to determine its status of completion. If City does not consider that part of the Work to be substantially complete, City will notify Contractor in writing giving the reasons therefor.   3. Partial Utilization will not constitute Final Acceptance by City.   14.05 Final Inspection   A. Upon written notice from Contractor that the entire Work is complete in accordance with the Contract Documents:   1. City will promptly schedule a Final Inspection with Contractor.   2. City will notify Contractor in writing of all particulars in which this inspection reveals that the Work is incomplete or defective. Contractor shall immediately take such measures as are necessary to complete such Work or remedy such deficiencies. B. City reserves the right to deny request for Final Inspection if City determines that the entire Work is not sufficiently complete to warrant a Final Inspection.   14.06 Final Acceptance   Upon completion by Contractor to City’s satisfaction, of any additional Work identified in the Final Inspection, City will issue to Contractor a letter of Final Acceptance.     00 72 00 - 1 GENERAL CONDITIONS Page 56 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 14.07 Final Payment   A. Application for Payment:   1. Upon Final Acceptance, and in the opinion of City, Contractor may make an application for final payment following the procedure for progress payments in accordance with the Contract Documents.   2.

B. Payment Becomes Due: 1. After City’s acceptance of the Application for Payment and accompanying documentation, requested by Contractor, less previous payments made and any sum City is entitled, including but not limited to liquidated damages, will become due and payable. 2. After all Damage Claims have been resolved: a. directly by the Contractor or; b. Contractor provides evidence that the Damage Claim has been reported to Contractor’s insurance provider for resolution. 3. The making of the final payment by the City shall not relieve the Contractor of any guarantees or other requirements of the Contract Documents which specifically continue thereafter.   14.08 Final Completion Delayed and Partial Retainage Release   A. If final completion of the Work is significantly delayed, and if City so confirms, City may, upon receipt of Contractor’s final Application for Payment, and without terminating the Contract, make payment of the balance due for that portion of the Work fully completed and accepted. If the remaining balance to be held by City for Work not fully completed or corrected is less than the retainage stipulated in Paragraph 14.02.C, and if bonds have been furnished as required in Paragraph 5.02, the written consent of the surety to the payment of the balance due for that portion of the Work fully completed and accepted shall be submitted by Contractor to City with the Application for such payment. Such payment shall be made under the terms and conditions   00 72 00 - 1 GENERAL CONDITIONS Page 57 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 governing final payment, except that it shall not constitute a waiver of Contract Claims.   B. Partial Retainage Release. For a Contract that provides for a separate vegetative establishment and maintenance, and test and performance periods following the completion of all other construction in the Contract Documents for all Work locations, the City may release a portion of the amount retained provided that all other work is completed as determined by the City. Before the release, all submittals and final quantities must be completed and accepted for all other work. An amount sufficient to ensure Contract compliance will be retained.   14.09 Waiver of Claims   The acceptance of final payment will constitute a release of the City from all claims or liabilities under the Contract for anything done or furnished or relating to the work under the Contract Documents or any act or neglect of City related to or connected with the Contract.   ARTICLE 15 – SUSPENSION OF WORK AND TERMINATION   15.01 City May Suspend Work   A. At any time and without cause, City may suspend the Work or any portion thereof by written notice to Contractor and which may fix the date on which Work will be resumed. Contractor shall resume the Work on the date so fixed. During temporary suspension of the Work covered by these Contract Documents, for any reason, the City will make no extra payment for stand-by time of construction equipment and/or construction crews.   B. Should the Contractor not be able to complete a portion of the Project due to causes beyond the control of and without the fault or negligence of the Contractor, and should it be determined by mutual consent of the Contractor and City that a solution to allow construction to proceed is not available within a reasonable period of time, Contractor may request an extension in Contract Time, directly attributable to any such suspension.   C. If it should become necessary to suspend the Work for an indefinite period, the Contractor shall store all materials in such a manner that they will not obstruct or impede the public unnecessarily nor become damaged in any way, and he shall take every precaution to prevent damage or deterioration of the work performed; he shall provide suitable drainage about the work, and erect temporary structures where necessary.   D. Contractor may be reimbursed for the cost of moving his equipment off the job and returning the necessary equipment to the job when it is determined by the City that construction may be resumed. Such reimbursement shall be based on actual cost to the Contractor of moving the equipment and no profit will be allowed. Reimbursement may not be allowed if the equipment is moved to another construction project for the City.   15.02 City May Terminate for Cause   A. The occurrence of any one or more of the following events by way of example, but not of   00 72 00 - 1 GENERAL CONDITIONS Page 58 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 limitation, may justify termination for cause:   1. Contractor’s persistent failure to perform the Work in accordance with the Contract Documents (including, but not limited to, failure to supply sufficient skilled workers or suitable materials or equipment, failure to adhere to the Project Schedule established under Paragraph 2.07 as adjusted from time to time pursuant to Paragraph 6.04.   2. Contractor’s disregard of Laws or Regulations of any public body having jurisdiction;   3. Contractor’s repeated disregard of the authority of City; or   4. Contractor’s violation in any substantial way of any provisions of the Contract Documents; or   5. Contractor’s failure to promptly make good any defect in materials or workmanship, or defects of any nature, the correction of which has been directed in writing by the City; or   6. Substantial indication that the Contractor has made an unauthorized assignment of the Contract or any funds due therefrom for the benefit of any creditor or for any other purpose; or   7. Substantial evidence that the Contractor has become insolvent or bankrupt, or otherwise financially unable to carry on the Work satisfactorily; or   8. Contractor commences legal action in a court of competent jurisdiction against the City.   B. If one or more of the events identified in Paragraph 15.02A. occur, City will provide written notice to Contractor and Surety to arrange a conference with Contractor and Surety to address Contractor's failure to perform the Work. Conference shall be held not later than 15 days, after receipt of notice.   1. If the City, the Contractor, and the Surety do not agree to allow the Contractor to proceed to perform the construction Contract, the City may, to the extent permitted by Laws and Regulations, declare a Contractor default and formally terminate the Contractor's right to complete the Contract. Contractor default shall not be declared earlier than 20 days after the Contractor and Surety have received notice of conference to address Contractor's failure to perform the Work.   2. If Contractor's services are terminated, Surety shall be obligated to take over and perform the Work. If Surety does not commence performance thereof within 15 consecutive calendar days after date of an additional written notice demanding Surety's performance of its obligations, then City, without process or action at law, may take over any portion of the Work and complete it as described below.   a. If City completes the Work, City may exclude Contractor and Surety from the site and take possession of the Work, and all materials and equipment incorporated into the   00 72 00 - 1 GENERAL CONDITIONS Page 59 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 Work stored at the Site or for which City has paid Contractor or Surety but which are stored elsewhere, and finish the Work as City may deem expedient. 3. Whether City or Surety completes the Work, Contractor shall not be entitled to receive any further payment until the Work is finished. If the unpaid balance of the Contract Price exceeds all claims, costs, losses and damages sustained by City arising out of or resulting from completing the Work, such excess will be paid to Contractor. If such claims, costs, losses and damages exceed such unpaid balance, Contractor shall pay the difference to City. Such claims, costs, losses and damages incurred by City will be incorporated in a Change Order, provided that when exercising any rights or remedies under this Paragraph, City shall not be required to obtain the lowest price for the Work performed. 4. Neither City, nor any of its respective consultants, agents, officers, directors or employees shall be in any way liable or accountable to Contractor or Surety for the method by which the completion of the said Work, or any portion thereof, may be accomplished or for the price paid therefor.   5. City, notwithstanding the method used in completing the Contract, shall not forfeit the right to recover damages from Contractor or Surety for Contractor's failure to timely complete the entire Contract. Contractor shall not be entitled to any claim on account of the method used by City in completing the Contract.   6. Maintenance of the Work shall continue to be Contractor's and Surety's responsibilities as provided for in the bond requirements of the Contract Documents or any special guarantees provided for under the Contract Documents or any other obligations otherwise prescribed by law.   C. Notwithstanding Paragraphs 15.02.B, Contractor’s services will not be terminated if Contractor begins within seven days of receipt of notice of intent to terminate to correct its failure to perform and proceeds diligently to cure such failure within no more than 30 days of receipt of said notice.   D. Where Contractor’s services have been so terminated by City, the termination will not affect any rights or remedies of City against Contractor then existing or which may thereafter accrue. Any retention or payment of moneys due Contractor by City will not release Contractor from liability.   E. If and to the extent that Contractor has provided a performance bond under the provisions of Paragraph 5.02, the termination procedures of that bond shall not supersede the provisions of this Article.   15.03 City May Terminate For Convenience   A. City may, without cause and without prejudice to any other right or remedy of City, terminate the Contract. Any termination shall be effected by mailing a notice of the termination to the   00 72 00 - 1 GENERAL CONDITIONS Page 60 of 63     CITY OF DENTON STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Revised September 20, 2018 Contractor specifying the extent to which performance of Work under the contract is terminated, and the date upon which such termination becomes effective. Receipt of the notice shall be deemed conclusively presumed and established when the letter is placed in the United States Postal Service Mail by the City.

This requirement may be waived at the discretion of the City if the supplier warrants that the asphalt binder can be adequately pumped, mixed and compacted at temperatures that meet all applicable safety, environmental, and constructability requirements. At test temperatures where the binder is a Newtonian fluid, any suitable standard means of viscosity measurement may be used, including capillary (AASHTO T201 or T202) or rotational viscometry (AASHTO T48 or T316). A waiver will need to be submitted to the City for approval prior to asphalt paving. 3. Viscosity at 135 degrees Celsius is an indicator of mixing and compaction temperatures that can be expected in the lab and field. High values may indicate high mixing and compaction temperatures. Additionally, significant variation can occur from batch to batch. Be aware that variation could significantly impact mixing and compaction operations. Contractor is responsible for addressing any constructability issues which may arise. 32 12 16 ASPHALT PAVING Page 14 of 42 CITY OF DENTON IFB No. 7452 STANDARD CONSTRUCTION SPECIFICATION DOCUMENTS Project # 200004 Revised July 28, 2020 4.
