The contract solicitation SOL1639377 is an indefinite-delivery/indefinite-quantity (IDIQ) agreement for on-call office engineering support services related to transportation projects in San Diego, California, with a maximum potential value of $20 million over a five-year period. The work encompasses full lifecycle support for capital improvement projects aligned with regional transportation plans, including planning, design, construction oversight, and closeout activities. Contractors will provide technical engineering services such as cost estimating, constructability reviews, QA/QC plan development, design updates, and reporting under task orders issued by the San Diego Association of Governments (SANDAG). Performance is centered in San Diego, with work also occurring at project sites across the region, and all deliverables must comply with Federal Transit Administration, Caltrans, and local jurisdictional standards. Submissions are evaluated on a best-value trade-off basis, prioritizing technical merit over cost, with the project team’s qualifications and proposed methodology carrying the highest weight. Key compliance requirements include certifications for drug-free workplace, debarment status, equal employment opportunity, Buy America, and lobbying restrictions, alongside California-specific obligations under Public Contract Code Sections 10162, 10232, and 10285.1, which address prevailing wages, apprenticeship programs, and prohibitions against fraud or bribery in public contracting. Proposers must demonstrate experience on similar projects, submit detailed staffing plans with key personnel roles and time commitments, and adhere to strict submission guidelines including electronic submission via BidNet Direct in PDF and Excel formats with defined page limits for narrative sections. No FOB terms or packaging requirements are specified, and payment and invoicing processes follow SANDAG’s internal formats without reference to federal systems like WAWF. All proposals must include completed certifications, a responsibility matrix, SF-330 forms, and documentation of small business status if applicable, with any organizational conflicts of interest mitigated through financial disclosures and strict gift prohibitions. The solicitation closes on September 14, 2026, with award anticipated to be made on a non-LPTA basis to the most qualified offeror.
