Commission hears first annual design‑build report; staff recommends peer review delayed until projects complete

Caltrans presented its first annual progress report on the department’s design‑build demonstration program and asked the Transportation Commission to authorize sending a midterm letter to the legislature explaining that no peer review committee findings can be produced until projects complete construction.

A Caltrans presenter described design‑build as a procurement method that awards contracts before design is complete to allow contractor input that can yield cost savings and greater constructability. The presenter said Senate Bill 4 (2009), codified in Public Contract Code section 6800 (as referenced in department materials), authorized the Department to use design‑build on up to 10 projects; the commission has authorized eight to date and six have been awarded.

The presenter reported early outcomes: bids on design‑build projects have come in «20–30% below estimates» in some cases, though the presenter noted some of the savings reflect broader economic conditions. Caltrans staff said design‑build has produced innovation — different bridge types, staging approaches and geometric changes — that has yielded up to roughly 10% savings on some projects.

A key administrative issue raised was the statute’s requirement to prequalify rather than shortlist proposers. Caltrans said prequalification has required reviewing up to eight proposers, imposing substantial proposal costs ("in the neighborhood of $250,000 to a million dollars" per proposer) and argued that shortlisting three to five firms would be more efficient. Staff said it will recommend statutory or policy changes to permit shortlisting in future reports.

On the commission’s statutory midterm report and peer review committee requirement, staff told commissioners that none of the design‑build projects authorized has completed construction, so the commission cannot yet produce peer review findings comparing design‑build to design‑bid‑build. Staff recommended that the commission authorize the executive director to send draft letters to the legislature explaining the absence of findings and pledging to establish the peer review committee once sufficient data exist. The commission approved that recommendation by voice vote.

Why it matters: The design‑build demonstration program tests a procurement method intended to accelerate schedules and encourage contractor innovation. The program’s early cost and schedule signals and proposals to change prequalification procedures could affect how high‑cost transportation projects are procured in the state.

Commission action and outcome: The commission voted to authorize the executive director to send the draft midterm letters to the legislature and accepted staff recommendations to report findings only once projects have produced sufficient data for peer review. The vote was recorded as approved on a voice vote.
