Where the work is, by district
What kind of work it is
Caltrans labels each proposal with a major work type. Here is what those categories usually involve, and how many proposals on this letting fall into each:
- Drainage / grading (2): earthwork, embankment, pipe and box culverts, inlets and ponds, often with the paving and erosion-control work that goes with them. Proposals: 04-2Y3014, 11-430914.
The work type is only a label. The bid item list and plans for each proposal show the real quantities. Subcontractors and suppliers should price from those, not from the category.
How to bid
- Licensing: contractors need a CSLB license in the right classification, and public works contractors must register with the Department of Industrial Relations. See our Caltrans bidding guide.
- Advertisements: Caltrans lists every project out for bid on its Contracts Out for Bid page, with the bid opening date and county.
- Submitting: Caltrans says electronic bidding for major construction contracts is available through Bid Express.
- Subcontractors and suppliers: our county hubs list the firms in each county, for example Alameda.
- Bonds: on public works over $25,000 the prime must post a payment bond (Civil Code § 9550).
