Agenda Title: PW-011, Bay Corridor Transmission and Distribution Phase 4 and Water Improvements Commission Meeting Date: May 28, 2024
Because the SFPUC anticipates that potential unforeseen conditions or other factors outside of the contractor’s control may impact the schedule, Staff included a requirement in the Invitation for Bids for bidders to provide a daily compensable time extensi on rate. At the bid opening, Staff announced that SFPUC would use the value of 60 days to calculate the Compensable Delay bid adjustment amount. Staff used the daily rate from the bids to determine the total Compensable Delay values shown in the table above by multiplying the bidder’s daily rate times 60. The Adjusted Bid value in the t able above is the sum of the Base Bid and Compensable Delay less any applicable LBE and SIP Program bid discounts. Staff used the Adjusted Bid value to compare and rank the bids to determine the lowest bidder. However, the contract award amount is the Base Bid value (not the Adjusted Bid value) and, if the Commission awards the Contract, the bidder’s daily compensable delay rate will become a term of the Contract.
Application of bid preferences in accordance with the Social Impact Partnership (SIP) Program did not change the final ranking of the low bidder.
Application of Local Business Enterprise (LBE) bid preferences do not apply to this contract because the engineer’s estimate is in excess of $10,000,000.

On May 30, 2023 , the San Francisco Planning Department determined the Project to be categorically exempt from environmental review under the CEQA Guidelines s ections 15302 and 15303, Class 2 (
