The change order grants a time extension of 1,000 calendar days and increases the contract amount by $5,411,816.28, bringing the total contract award from $7,253,128.25 to $12,664,944.53. The change order is due to differing subsurface conditions, unforeseen conflicts with communication and electrical duct banks, and includes a credit for concrete manhole substitution and replenishes the contingency allowance. The resolution authorizes the County Mayor or designee to execute the change order and use funds from the Building Better Communities General Obligation Bond (GOB) Program Project No. 17.

The Substantial Completion Date is revised from May 21, 2024 to February 15, 2027, and the Final Completion Date from June 20, 2024 to March 17, 2027. The change order includes $4,680,600.00 for differing sub-surface conditions with a 908-calendar day extension, $595,409.58 for contingency replenishment, $167,731.70 for duct bank conflicts with a 92-calendar day extension, and a $31,925.00 savings for concrete manhole substitution. The contract had an 8 percent SBE-Goods goal and an 18 percent SBE-Con goal; the SBE-Con goal is recommended to be removed. The final action was adopted on July 21, 2026.
