ISSUE BEFORE COUNCIL: Should the City Council accept the improvements, approve Compensating Change Order No. 1, and approve Pay Request No. 4 (Final) for the Well No. 1 Abandonment and Pumphouse Demolition?
BACKGROUND: Keys Well Drilling Company was awarded a construction contract on June 7, 2022 to complete the Well No. 1 Abandonment and Pumphouse Demolition. The contractor has now completed the work in accordance with the contract, plans, and specifications, including all punch list items. PROPOSAL DETAILS/ANALYSIS: A compensating change order has been prepared and executed for the project to reconcile the estimated and actual quantities installed. With approval of this compensating change order the contract amount will be adjusted to reflect the actual final project quantities. In addition, Keys Well Drilling Company has submitted Partial Pay Request No. 4 (Final) in the amount of $4,220.75. The Project Engineer has prepared a Certificate of Completion indicating that all work is completed, including all punch list items, and is recommending the acceptance of the improvements and release of final retainage. Project acceptance will initiate the one-year warranty period for the improvements. The one-year warranty will begin on November 15, 2022 and will extend through November 15, 2023. FISCAL IMPACT: None. Final payment is being recommended within the authorized scope and budget for the project. The final construction contract amount of $84,415.00 is under the original construction contract amount of $119,815.00. The compensating change order will officially decrease the final
construction contract amount by $35,400.00. RECOMMENDATION: Staff is recommending that the City Council, as part of the Consent Agenda,
accept the improvements, approve Compensating Change Order No. 1, and approve Pay Request No. 4 (Final) for the Well No. 1 Abandonment and Pumphouse Demolition. If removed from the consent agenda, the recommended motion for the action is as follows: “Move to accept the improvements for the Well No. 1 Abandonment and Pumphouse Demolition, approve Compensating Change Order No. 1 decreasing the contract amount by $35,400, and approve
Pay Request No. 4 (Final) to Keys Well Drilling Company in the amount of $4,220.75.” ATTACHMENTS: 1. Compensating Change Order No. 1.
