At all times Owner’s Representative and appropriate inspectors shall have access to the Work for inspection and testing. Contractor shall provide proper and safe conditions for such access.
2. Where any law, ordinance, rule, regulation, code, or other order of any public body having jurisdiction requires any Work or part thereof to specifically inspected, tested or approved, Contractor shall assume full responsibility for such inspection, testing, or approval, and pay all costs in connection therewith and furnish Owner’s Representative with the required certificates of inspection, testing or approval. If any Work to be inspected, tested, or approved is covered without written concurrence of Owner’s Representative, it must be, if requested, uncovered for observation. Such uncovering shall be at Contractor's expense.
3. Neither observations by the Owner’s Representative nor inspection tests or approvals by others shall relieve the Contractor from his obligations to perform the Work in accordance with the contract documents.
4. If, within two (2) years after the date of final completion and sign off and payment of any retainage by Owner to Contractor, there is any defect in materials or workmanship, Contractor shall promptly, without cost to Owner and in accordance with Owner's written instructions, either correct such defective Work or, if it has been rejected by Owner, remove it from the site and replace it with non-defective Work.

Section 19. Payments to Contractor.
1. By the 5th day of each month, Contractor will submit to Owner’s Representative a partial payment estimate filled out and signed by Contractor covering the Work performed during the period covered by the partial payment estimate and supported by such data as Owner’s Representative may reasonably require. If payment is requested on the basis of materials and equipment not incorporated in the Work but delivered and suitably stored at or near the site, the partial payment estimate shall also be accompanied by such supporting data, satisfactory to Owner, as will establish Owner’s title to the material and equipment, and protect its interest therein, including applicable insurance. Owner’s Representative will, within ten (10) days after receipt of each partial payment estimate, either indicate in writing his approval of payment and present the partial payment estimate to Owner, or return the partial payment estimate to Contractor indicating in writing his reasons for refusing to approve payment. In the latter case, Contractor may make the necessary corrections and resubmit the partial payment estimate. Owner will, within ten (10) days of the next City Council meeting after presentation by Owner’s Representative of an approved partial payment estimate, pay Contractor a progress payment on the basis of the approved partial payment estimate. Owner shall retain five percent (5%) of the amount of each payment until final completion and acceptance of all Work covered by the contract documents. After fifty percent (50%) of the Work has been completed, Owner may, at Owner’s sole discretion, reduce or eliminate retainage on the remaining progress estimates. When the Work is substantially complete, Owner may, at Owner’s sole discretion, further reduce the retained amount below 5% to only that amount necessary to assure completion. On completion and acceptance of a part of the Work on which the price is stated separately in the contract documents, Owner may, in Owner’s sole discretion, pay for that part of the Work in full, including retained percentages, less authorized deductions.
2. A request for payment may also include an allowance for the cost of such major materials and equipment which are suitably stored either at or near the site.
3. Prior to Substantial Completion, Owner, with the approval of Owner’s Representative and with the concurrence of the Contractor, may use any completed or substantially completed portions of the Work. Such use shall not constitute an acceptance of such portions of the Work.
4. Owner shall have the right to enter the premises for the purpose of doing Work not covered by the contract documents. This provision shall not be construed as relieving Contractor of the sole responsibility for the care and protection of the Work, or the restoration of any damaged Work except such as may be caused by
CITY PARK IMPROVEMENTS PHASE II 46 GENERAL CONDITIONS agents or employees of Owner. Such entry or Work shall only be allowed to the extent it does not interfere with Contractor's Work.
5. Upon completion and acceptance of the Work, Owner’s Representative shall issue a certificate attached to the final payment request that the Work has been accepted by him under the conditions of the contract documents. The entire balance found to be due the Contractor, including the retained percentages, but except such sums as may be lawfully retained by Owner, shall be paid to the Contractor within thirty (30) days of the issuance of the certificate of completion and acceptance of the Work.
6. Contractor will indemnify and save Owner and Owner’s officials, employees, agents, and volunteers harmless from all claims arising out of the lawful demands of Subcontractors, laborers, workmen, mechanics, materialmen, and furnishers or machinery and parts thereof, equipment, tools, and all supplies, incurred in the furtherance of the performance of the Work. Contractor shall, at Owner’s request, furnish satisfactory evidence that all obligations of the nature designated above have been paid, discharged or waived. If Contractor fails to do so, Owner may, after having notified Contractor, either pay unpaid bills or withhold from Contractor's unpaid compensation a sum of money deemed reasonably sufficient to pay any and all such lawful claims until satisfactory evidence is furnished that all liabilities have been fully discharged whereupon payment to Contractor shall be resumed in accordance with the terms of the contract documents, but in no event shall the provisions of this Section be construed to impose any obligations upon Owner to either Contractor, Contractor’s surety or any third party. In paying any unpaid bills of Contractor, any payment so made by Owner shall be considered as a payment made under the contract documents by Owner to Contractor and Owner shall not be liable to Contractor for any such payments made in good faith.
7. If Owner fails to make payment thirty (30) days after approval of a partial payment estimate by Owner’s Representative, in addition to the other remedies available to Contractor, there shall be added to each such payment interest at the maximum legal rate commencing on the first day after said payment is due and continuing until the payment is received by the Contractor.
Section 20. Cleanup.
1. From time to time as the Work progresses and immediately after completion of the Work, Contractor shall clean up and remove all refuse and unused materials of any kind resulting from the Work. Upon failure of Contractor to do so within 24 hours after being so directed by Owner’s Representative, the Work may be done by Owner and the cost thereof may be deducted from any payment due Contractor.
CITY PARK IMPROVEMENTS PHASE II 47 GENERAL CONDITIONS 2. After all other Work embraced in the contract is completed and before final acceptance of the contract, the entire right of way and driveways, alleys, and side street approaches, slopes, ditches, utility trenches, and construction areas shall be neatly finished to the lines, grades and cross sections shown in the specifications.
3. As a condition precedent to final acceptance of the Project, Contractor shall remove all equipment and temporary structures, and all rubbish, waste and generally clean the right of way and premises.
Section 21. Use of Light, Power and Water.
Contractor shall furnish temporary light, power, and water complete with connecting piping, wiring, lamps, and similar equipment necessary before the Work is improved. Contractor shall install, maintain and remove temporary lines upon completion of Work. Contractor shall obtain all permits and bear all costs for connection with temporary services and facilities at no expense to Owner.
Section 22. Arbitration.
1. All claims, disputes, and other matters in question between Owner and Contractor arising out of, or relating to, the contract documents, including rescission, reformation, enforcement, or the breach of the terms thereof, except for claims which may have been waived by the making or acceptance of final payment or for acquisition of property subject to eminent domain, may be decided by arbitration. Owner shall have the sole discretion as to whether or not a dispute will be decided by arbitration conducted in Lane County, Oregon, rather than through the court process.
2. No demand for arbitration of any claimed dispute or other matter shall be effective until after a claim or demand regarding the underlying dispute is made to the City Council and the Council at its next regularly scheduled meeting, has rendered a written decision with respect thereto denying the claim or demand. No demand for arbitration of the denial of any such claim, dispute, or other matter shall be made later than thirty (30) days after the date on which the City Council has rendered a written decision denying the claim. The failure to demand arbitration within thirty (30) days of the date of the City Council’s decision denying the claim shall result in the City Council’s decision being binding upon Owner and Contractor.
3. Notice of demand for arbitration shall be filed in writing with the other party to the agreement. The demand for arbitration shall be made within the 30 day period specified above. Owner, if not the party demanding arbitration, has the option of allowing the matter to proceed with arbitration or by Written Notice within five (5) days after receipt of a demand for arbitration, or rejecting arbitration and requiring Contractor to proceed through the courts for relief. Arbitration shall be
CITY PARK IMPROVEMENTS PHASE II 48 GENERAL CONDITIONS conducted under the Uniform Arbitration Act, ORS 36.600 et seq. If the parties are unable to mutually select an arbitrator within twenty (20) days following Owner’s decision to pursue arbitration, then each party shall select an arbitrator, and the two arbitrators shall select a single arbitrator. The arbitrator(s) shall have substantial experience in construction disputes. The parties agree that any award rendered by the arbitrator will be final, and judgment may be entered upon the award in any court having jurisdiction thereof, and will not be subject to modification or appeal except to the extent permitted by Oregon law.
Section 23. Attorney Fees.
If suit, action or arbitration is brought either directly or indirectly to rescind or enforce the terms of this agreement, the prevailing party shall recover and the losing party hereby agrees to pay reasonable attorney's fees incurred in such proceeding, in both the trial and appellate courts, as well as any costs and disbursements. Further, if it becomes necessary for Owner to incur the services of an attorney to enforce any provision of this agreement without initiating litigation, Contractor agrees to pay Owner’s attorney's fees so incurred. Such costs and fees shall bear interest at the maximum legal rate from the date incurred, until the date paid by losing party.
