Description

Caltrans is seeking a qualified architectural‑engineering firm (or consortium) to provide on‑call hazardous‑waste site investigation and design services throughout District 4 (Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, Sonoma). The contract is “as‑needed,” meaning work will be issued via individual task orders over a three‑year period. The firm must demonstrate extensive experience in hazardous‑waste investigations, environmental assessments, and remedial‑design, and must staff a Consultant Contract Manager with at least five years of CCM experience and ten years of hazardous‑waste project experience. Vendor trade services are to be submitted via rate sheets rather than traditional multiple bids, and any use of Generative AI must be disclosed in the transmittal letter. The estimated contract value is $3.2 M‑$5.2 M, with a 10 % profit fee and scheduled escalations.

Budget estimate

$3,200,000 – $5,200,000

The solicitation lists an estimated contract ceiling of $3.2 million to $5.2 million over three years. Assuming the firm secures the full award, the expected earnings would fall within that range. The low end reflects a modest task‑order volume; the high end assumes near‑maximum utilization of the on‑call capacity, including the 10 % fee and scheduled escalations.
