Rehabilitation of the South Apron was included in the FY 2022/23 Airport Improvements CIP Program. On April 25, 2023, City Council awarded a contract to Con-Struct, Inc. for the work in the amount of $1,251,705. Change Order No. 1 required no additional funding, however it added requirements for Targeted Small Business (TSB) participation. Change Order No. 2, in the amount of $13,888.60, was administratively approved by staff and addressed gate and fencing revisions required during construction operations. Change Order No. 3, in the amount of $21,866, was also administratively approved by staff to cover changes to the work to further address airport operational needs. Change Order No. 4 (This Action), is the balancing change order for the project, a deduction in the amount of ($35,531.35). This change order reflects final field installed quantities. Because the sum of the absolute values of all of the project change orders exceeds $50,000, approval by City Council is required.

Approve Change Order #4, a reduction in the amount of ($35,531.35). 2. Direct Staff to make modifications to the project. CITY MANAGER'S RECOMMENDED ACTION: Change Order No. 4 represents the final reconciliation of actual field quantities and must be completed prior to the engineer ’s final statement of completion in accordance with FAA and State grant requirements. Therefore, it is the recommendation of the City Manager that the City Council adopt Alternative No. 1, as noted above.
