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 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 60- days to calculate the c ompensable 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 m ultiplying the bidder’s daily rate times 60. 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.
Protest: On September 18, 2025, the SFPUC received three bid protests as follows:
1. Anvil Builders, Inc. challenging the bid submitted by Mountain Cascade, Inc.
2. Western Water Constructors, Inc. challenging the bid submitted by Mountain Cascade, Inc.
3. Western Water Constructors, Inc. challenging the bid submitted by Anvil Builders, Inc.
On September 25, 2025, Mountain Cascade, Inc. and Anvil Builders, Inc., submitted response letters. On October 30, 2025, after review of the protests and responses, the Contract Administration Bureau, in consultation with the City Attorney and Contract Monitoring Division, issued determination letters denying the protests and determined Mountain Cascade, Inc., to be the responsible bidder that submitted the lowest responsive bid.
