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, the balancing change order for the project, a deduction in the
amount of $35,531.35 was approved by City Council on July 8, 2025. This change order
reflected final field installed quantities.
