Bid openings run from Nov. 2 to Dec. 17, 2026. Most of the projects list a General Engineering (A) license, and 44 also list Earthwork and Paving (C-12).

General Building (B) is the most common primary license among firms in the directory; the state's 13,422 General Engineering (A) firms are the pool for most Caltrans work.

A preliminary notice protects work back 20 days. Direct contractors and subcontractors have different recording windows, and a recorded notice of completion shortens both.

Caltrans' contracting guide says to allow at least seven days to set up electronic bidding, and Bid Express charges fees for the digital ID.

Drainage restoration, infiltration areas, bioswales and treatment BMPs in Los Angeles and Ventura counties open between Nov. 3 and Dec. 9, most listing Sanitation System (C-42) licenses.
