Caltrans electronic bidding provides flexibility to you. In case of an emergency due to natural circumstances causing electrical shut off or if you are simply away from your machine for any reason and need to submit your bid, the Digital ID for Project Bids can be distributed across several machines. You will be able to submit your project bids from the location of your choosing. Additionally, all projects are advertised for three to seven weeks and bids can be submitted and resubmitted at anytime prior to bid opening.
