BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
On April 2, 2024, the City Council awarded Bid 23-294 to Performance Construction and Engineering for an amount not to exceed $5,173,148.07 to install a water main on River Road from Aurora Avenue to the BNSF right-of-way and on Aurora Avenue from River Road to Wild Cherry Road.
The contract included a completion date of October 31, 2024.
DISCUSSION:
Unforeseen site conditions beyond the contractor's control necessitated this Change Order which includes final balancing changes reflecting as-built quantities for the contract pay items along with extra work items deemed necessary to ensure a successful project. The major extra work items include an additional 800 feet of water main not quantified in the contract, exploratory work and revisions at various locations, additional valving, additional pavement removal, and remedial work to correct a plan discrepancy at All Saints School.
The original contract included a contingency of 3%, or $155,194.44. Staff is requesting additional funds for this Change Order. The contingency will be retained to address any final work items to be completed in the spring. The tables below provide a summary of the award and contingency amount.
