Stanislaus County HBP - Scour Countermeasure Project: East Avenue over TID Main Canal and Lake Road over Peaslee Creek

The Stanislaus County Public Works Department is soliciting proposals for the design of scour countermeasures for two bridges funded by the Caltrans Highway Bridge Program: the Lake Road bridge over Peaslee Creek and the East Avenue bridge over the TID Main Canal. The scope of work includes all-inclusive consulting services such as topographic and boundary surveys, utility design and coordination, public outreach, and bidding and construction support. Specifically, the project requires scour protection to prevent undermining of the spread footing at Abutment 2 for the Lake Road bridge and protection at both abutments, including wing walls, for the East Avenue bridge. All designs must adhere to the latest Caltrans Standards and Specifications, Caltrans Structure Design Standards, and County requirements. Selection is based on a qualifications-based procurement using a one-step RFP method from the Caltrans Local Assistance Procedures Manual. Consultants are scored out of 100 points based on their qualifications and proposal quality, with the top-ranked firm entering negotiations for a contract using the Actual Cost-Plus Fixed Fee payment method. Proposals must be submitted in PDF format on a USB flash drive, with cost proposals provided in a separate, sealed envelope to avoid disqualification. The project mandates strict compliance with federal and state regulations, including Buy America requirements for steel and iron, ADA accessibility standards for digital deliverables, and non-discrimination laws. Invoices must be detailed by milestone and approved by the Local Agency Contract Administrator, with final submission required within 60 calendar days of project completion.
