security specified in Caltrans Standard Specifications in an amount of at least ten (10) percent of the total of the

bidders' security not forfeited to the City will be returned once a successful bidder provides all required documents

bidder's security to the City will not waive or otherwise limit any other remedy available to the City under
applicable law.

of Part 2 of Division 7 of the Business and Professional Code), arising from purchases of goods, services or

bidder, but must timely pursue its own protest.
5.5. The procedure and time limits set forth in these Instructions to Bidders are mandatory and are the bidders' sole and
exclusive remedy in the event of a bid protest. Any bidder's failure to fully comply with these procedures shall
constitute a waiver of any right to further pursue a bid protest, including filing of a challenge of the award pursuant

any other legal proceedings.
