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.
To submit your bids from any of these machines at any time, the Digital ID for Project Bids would need be imported into the AASHTOWare Project Bids Bid software by following below steps:
  • Open AASHTOWare Project Bids Bid
  • Navigate to Tools > Manage Digital IDs
  • Click the green + sign on the righthand side
  • Find the digital ID.cer file on the machine
  • Enter the Digital ID and password
  • The Digital ID should now be successfully imported
  • Check the Digital ID under Tools> Manage Digital IDs where it should be listed
