Application of bid preferences in accordance with Chapter 14B of the San Francisco Administrative Code did not change the final ranking of the low bidder.
Because the SFPUC anticipates that potential unforeseen conditions or other factors outside the contractor’s control may impact the schedule, Staff included a requirement in the Invitation Agenda Title: WW-766, Oceanside Water Pollution Control Plant 930 Administration and Lab Structure Health and Safety Improvements Commission Meeting Date: June 23, 2026
for Bids for bidders to provide a daily compensable time extension rate. At the bid opening, Staff announced that SFPUC would use the value of 75-
days to calculate the compensable delay bid
adjustment amount. Staff used the daily rate in each bid to determine the total Compensable Delay value shown in the table above by multiplying the bidder’s daily rate times 75. The Adjusted Bid value in the table above is the sum of the Base Bid Amount and Compensable Delay less any applicable bid discount. 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.
Environmental
Review:
This action does not constitute a project under the California Environmental Quality Act Guidelines Section 15378 because it will not result in a physical change in the environment.
