Project Bids Access

CDOT will be upgrading the AASHTOWare Project Expedite system to a new application called AASHTOWare Project Bids™.  

Effective:  March 31, 2016 letting

If you would like to bid with CDOT on or after the March 31, 2016 letting, you will need to complete the following three steps:

  1. Download the new software by clicking here.
  2. Create a new Info Tech Digital ID through the Bid Express website. If you currently have an active Info Tech Digital ID for CDOT, you will be reimbursed for the cost of creating the new Digital ID.
  3. Request to bid with CDOT through the Bid Express website

Once CDOT receives your request to bid, we will verify the information with the current Prequalification information (e.g., the agent on the Digital ID is same as the authorized agent on the Prequalification document). We will then approve or reject the organization for bidding - which will allow you to submit a bid to CDOT on and after the March 31 letting.

What is a Digital ID?

A digital ID is an electronic tool that enables contractors digitally sign bids electronically and submit them over the Internet.

What is the difference between a Digital ID and a Vendor ID (Bidder ID)?

A digital ID is provided by InfoTech (BidExpress) to enable a contractor to digital sign bids electronically and securely over the Internet.  A vendor ID (or bidder ID) is provided to the contractor as part of the CDOT registration and prequalification process as a unique identifier for the specific contractor/vendor.

What is an "Amendment?"

When CDOT changes a proposal, we must issue an "amendment" file for contractors to download to keep their proposal current.  The amendment may include any type of change in the proposal from a removal of an item to a change in an amount of an item.
