G. Performance, Payment and Maintenance Bonds The Contractor shall procure and pay for performance and payment bonds applicable to the work in the amount of the total bid price. The Contractor shall also procure and pay for a maintenance bond applicable to the work in the amount of fifteen percent (15%) of the total bid price. The period of the Maintenance Bond shall be two years from the date of acceptance of all work done under the contract, to cover the guarantee as set forth in the Special Conditions. The performance, payment and maintenance bonds shall be issued in the form attached to this Construction Agreement as Exhibits B, C and D. Other performance, payment and maintenance bond forms shall not be accepted. Among other things, these bonds shall apply to any work performed during the two-year warranty period after acceptance as described in this Construction Agreement. The performance, payment and maintenance bonds shall be issued by a corporate surety, acceptable to and approved by the Town, authorized to do business in the State of Texas, pursuant to Chapter 2253 of the Texas Government Code. Further, the Contractor shall supply capital and surplus information concerning the surety and reinsurance information concerning the performance, payment and maintenance bonds upon Town request. In addition 7 to the foregoing requirements, if the amount of the bond exceeds One Hundred Thousand Dollars ($100,000) the bond must be issued by a surety that is qualified as a surety on obligations permitted or required under federal law as indicated by publication of the surety's name in the current U.S. Treasury Department Circular 570. In the alternative, an otherwise acceptable surety company (not qualified on federal obligations) that is authorized and admitted to write surety bonds in Texas must obtain reinsurance on any amounts in excess of One Hundred Thousand Dollars ($100,000) from a reinsurer that is authorized and admitted as a reinsurer in Texas who also qualifies as a surety or reinsurer on federal obligations as indicated by publication of the surety's or reinsurer's name in the current U.S. Treasury Department Circular 570. H. Progress Payments and Retainage As it completes portions of the Work, the Contractor may request progress payments from the Owner. Progress payments shall be made by the Owner based on the Owner's estimate of the value of the Work properly completed by the Contractor since the time the last progress payment was made. The "estimate of the value of the work properly completed" shall include the net invoice value of acceptable, non-perishable materials actually delivered to and currently at the job site only if the Contractor provides to the Owner satisfactory evidence that material suppliers have been paid for these materials. No progress payment shall be due to the Contractor until the Contractor furnishes to the Owner: 1. copies of documents reasonably necessary to aid the Owner in preparing an estimate of the value of Work properly completed; 2. full or partial releases of liens, including releases from subcontractors providing materials or delivery services relating to the Work, in a form acceptable to the Owner releasing all liens or claims relating to goods and services provided up to the date of the most recent previous progress payment; 3. an updated and current schedule clearly detailing the project's critical path elements in accordance with SC.11 CONSTRUCTION SCHEDULE; and 3. any other documents required under the Contract Documents. Progress payments shall not be made more frequently than once every thirty (30) calendar days unless the Owner determines that more frequent payments are appropriate. Further, progress payments are to be based on estimates and these estimates are subject to correction through the adjustment of subsequent progress payments and the final payment to Contractor. If the Owner determines after final payment that it has overpaid the Contractor, then Contractor agrees to pay to the Owner the overpayment amount specified by the Owner within thirty (30) calendar days after it receives written demand from the Owner. The fact that the Owner makes a progress payment shall not be deemed to be an admission by the Owner concerning the quantity, quality or sufficiency of the Contractor's work. Progress payments shall not be deemed to be acceptance of the Work nor shall a progress payment release the Contractor from any of its responsibilities under the Contract Documents. 8 After determining the amount of a progress payment to be made to the Contractor, the Owner shall withhold a percentage of the progress payment as retainage. The amount of retainage withheld from each progress payment shall be set depending upon the value of the Contract Work on the effective date of the Contract: Contract Amount Retainage Percentage Up to $25,000 15% $25,000 to $400,000 10% Over$400,000 5% Retainage shall be withheld and may be paid to: a. ensure proper completion of the Work. The Owner may use retained funds to pay replacement or substitute contractors to complete unfinished or defective work; b. ensure timely completion of the Work. The Owner may use retained funds to pay liquidated damages; and C, provide an additional source of funds to pay claims for which the Owner is entitled to indemnification from Contractor under the Contract Documents. Retained funds shall be held by the Owner in accounts that shall not bear interest. Retainage not otherwise withheld in accordance with the Contract Documents shall be returned to the Contractor as part of the final payment. I. Withholding Payments to Contractor The Owner may withhold payment of some or all of any progress or final payment that would otherwise be due if the Owner determines, in its discretion, that the Work has not been performed in accordance with the Contract Documents. The Owner may use these funds to pay replacement or substitute contractors to complete unfinished or defective Work. The Owner may withhold payment of some or all of any progress or final payment that would otherwise be due if the Owner determines, in its discretion, that it is necessary and proper to provide an additional source of funds to pay claims for which the Owner is entitled to indemnification from Contractor under the Contract Documents. Amounts withheld under this section shall be in addition to any retainage. J. Acceptance of the Work When the Work is completed, the Contractor shall request that the Owner perform a final inspection. The Owner shall inspect the Work. If the Owner determines that the Work has been completed in accordance with the Contract Documents, it shall issue a written notice of acceptance of the Work. If the Owner determines that the Work has not been completed in 9 accordance with the Contract Documents, then it shall provide the Contractor with a verbal or written list of items to be completed before another final inspection shall be scheduled. It is specifically provided that Work shall be deemed accepted on the date specified in the Owner's written notice of acceptance of the Work. The Work shall not be deemed to be accepted based on "substantial completion" of the Work, use or occupancy of the Work, or for any reason other than the Owner's written Notice of Acceptance. Further, the issuance of a certificate of occupancy for all or any part of the Work shall not constitute a Notice of Acceptance for that Work. In its discretion, the Owner may issue a Notice of Acceptance covering only a portion of the Work. In this event, the notice shall state specifically what portion of the Work is accepted. K. Acceptance of Erosion Control Measures When the erosion control measures have been completed, the Contractor shall request that the Owner perform a final inspection. The Owner shall inspect the Work. If the Owner determines that the Work has been completed in accordance with the Contract Documents and per TPDES General Construction Permit, it shall issue a written Notice of Acceptance of the Work. If the Owner determines that the Work has not been completed in accordance with the Contract Documents or TPDES General Construction Permit, then it shall provide the Contractor with a verbal or written list of items to be completed before another final inspection shall be scheduled. L. Final Payment After all Work required under the Contract Documents has been completed, inspected, and accepted, the Town shall calculate the final payment amount promptly after necessary measurements and computations are made. The final payment amount shall be calculated to: 1. include the estimate of the value of Work properly completed since the date of the most recent previous progress payment; 2. correct prior progress payments; and 3. include retainage or other amounts previously withheld that are to be returned to Contractor, if any. Final payment to the Contractor shall not be due until the Contractor provides original full releases of liens from the Contractor and its subcontractors, or other evidence satisfactory to the Owner to show that all sums due for labor, services, and materials furnished for or used in connection with the Work have been paid or shall be paid with the final payment. To ensure this result, Contractor consents to the issuance of the final payment in the form of joint checks made payable to Contractor and others. The Owner may, but is not obligated to issue final payment using joint checks. Final payment to the Contractor shall not be due until the Contractor has supplied to the Owner original copies of all documents that the Owner determines are reasonably necessary to ensure both that the final payment amount is properly calculated and that the Owner has satisfied its obligation to administer the Construction Agreement in accordance with applicable 10 law. The following documents shall, at a minimum, be required to be submitted prior to final payment being due: redline as-built construction plans; consent of surety to final payment; public infrastructure inventory; affidavit of value for public infrastructure; and, final change order(s). "Redline as-built construction plans" shall include, but are not limited to markups for change orders, field revisions, and quantity overruns as applicable. The list of documents contained in this provision is not an exhaustive and exclusive list for every project performed pursuant to these Contract Documents and Contractor shall provide such other and further documents as may be requested and required by the Owner to close out a particular project. Subject to the requirements of the Contract Documents,. the Owner shall pay the Final Payment within thirty (30) calendar days after the date specified in the Notice of Acceptance. This provision shall apply only after all Work called for by the Contract Documents has been accepted. M. Contractor's Warranty For a two-year period after the date specified in a written notice of acceptance of Work, Contractor shall provide and pay for all labor and materials that the Owner determines are necessary to correct all defects in the Work arising because of defective materials or workmanship supplied or provided by Contractor or any subcontractor. This shall also include areas of vegetation that did meet TPDES General Construction Permit during final close out but have since become noncompliant. Forty-five (45) to sixty (60) calendar days before the end of the two-year warranty period, the Owner may make a warranty inspection of the Work. The Owner shall notify the Contractor of the date and time of this inspection so that a Contractor representative may be present, After the warranty inspection, and before the end of the two-year warranty period, the Owner shall mail to the Contractor a written notice that specifies the defects in the Work that are to be corrected. The Contractor shall begin the remedial work within ten (10) calendar days after receiving the written notice from the Town. if the Contractor does not begin the remedial work timely or prosecute it diligently, then the Owner may pay for necessary labor and materials to effect repairs and these expenses shall be paid by the Contractor, the performance bond surety, or both. If the Owner determines that a hazard exists because of defective materials and workmanship, then the Owner may take steps to alleviate the hazard, including making repairs. These steps may be taken without prior notice either to the Contractor or its surety. Expenses incurred by the Owner to alleviate the hazard shall be paid by the Contractor, the performance bond surety, or both. Any Work performed by or for the Contractor to fulfill its warranty obligations shall be performed in accordance with the Contract Documents. By way of example only, this is to ensure that Work performed during the warranty period is performed with required insurance and the performance and payment bonds still in effect. Work performed during the two-year warranty period shall itself be subject to a one-year warranty. This warranty shall be the same as described in this section. 11 The Owner may make as many warranty inspections as it deems appropriate. N. Compliance with Laws The Contractor shall be responsible for ensuring that it and any subcontractors performing any portion of the Work required under the Contract Documents comply with all applicable federal, state, county, and municipal laws, regulations, and rules that relate in any way to the performance and completion of the Work. This provision applies whether or not a legal requirement is described or referred to in the Contract Documents. Ancillary / Integral Professional Services: In selecting an architect, engineer, land surveyor, or other professional to provide professional services, if any, that are required by the Contract Documents, Contractor shall not do so on the basis of competitive bids but shall make such selection on the basis of demonstrated competence and qualifications to perform the services in the manner provided by Section 2254.004 of the Texas Government Code and shall so certify to the Town the Contractor's agreement to comply with this provision with Contractor's Bid Proposal. O. Other Items The Contractor shall sign the Construction Agreement, and deliver signed performance, payment and maintenance bonds and proper insurance policy endorsements (and/or other evidence of coverage) within ten (10) calendar days after the Owner makes available to the Contractor copies of the Contract Documents for signature. Six (6) copies of the Contract Documents shall be signed by an authorized representative of the Contractor and returned to the Town. The Construction Agreement "effective date" shall be the date on which the Town Council acts to approve the award of the Contract for the Work to Contractor. It is expressly provided, however, that the Town Council delegates the authority to the Town Manager or his designee to rescind the Contract award to Contractor at any time before the Owner delivers to the Contractor a copy of this Construction Agreement that bears the signature of the Town Manager and Town Secretary or their authorized designees. The purpose of this provision is to ensure: 1. that Contractor timely delivers to the Owner all bonds and insurance documents; and 2. that the Owner retains the discretion not to proceed if the Town Manager or his designee determines that information indicates that the Contractor was not the lowest responsible bidder or that the Contractor cannot perform all of its obligations under the Contract Documents. THE CONTRACTOR AGREES. THAT IT SHALL HAVE NO CLAIM OR CAUSE OF ACTION OF ANY KIND AGAINST OWNER, INCLUDING A CLAIM FOR BREACH OF CONTRACT, NOR SHALL THE OWNER BE REQUIRED TO PERFORM UNDER THE CONTRACT DOCUMENTS, UNTIL THE DATE THE OWNER DELIVERS TO THE CONTRACTOR A COPY OF THE CONSTRUCTION AGREEMENT BEARING THE SIGNATURES ,JUST SPECIFIED. 12 The Contract Documents shall be construed and interpreted by applying Texas law. Exclusive venue for any litigation concerning the Contract Documents shall be Tarrant County, Texas.

The Contract Documents are binding upon the Owner and Contractor and shall insure to their benefit and as well as that of their respective successors and assigns. If Town Council approval is not required for the Construction Agreement under applicable law, then the Construction Agreement "effective date" shall be the date on which the Town Manager and Town Secretary or their designees have signed the Construction Agreement. If the Town Manager and Town Secretary sign on different dates, then the later date shall be the effective date.
