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 extension rate. At the bid opening, Staff announced that SFUPC would use the value of a 58-
day compensable delay to calculate the Compensable Delay amount bid adjustment. Staff used the daily rate in each bid to determine the total Compensable Delay value shown in the table by multiplying the bidder’s daily rate times 58. The Adjusted Bid value in the table is the sum of the Base Bid and Compensable Delay less any applicable LBE 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.
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.
