Downloading of Project Bids Software required to bid on CDOT Highway and Bridge Construction Projects

CDOT no longer uses AASHTOWare Expedite software, we've upgrated to ASHTOWare Project Bids.  To bid on projects advertised by CDOT, contractors must use AASHTOWare Project Bids software and obtain new digital ID with Bid Express. To download AASHTOWare Project Bids, please click here: Detailed instructions on the installation are found at AASHTOWare Project Bids Quick Start Guide and the AASHTOWare Project Bids Bid User’s Guide. It is recommended you read these instructions before installing AASHTOWare Project Bids. NOTE: If you have already installed AASHTOWare Project Bids for another state DOT, you do not need to repeat the process for CDOT. You will, however, have to create your "Agency/ID" record as indicated in the installation instructions.

Instructions for Loading Amendments

Double click on the main .EBSX file of the project of interest.  Select "save" and then select the location where you want to save the file.  When the download is complete, select "close."  (The saved file will have a suffix "ebsx."). Then double click on the amended file for the same project of interest.  Select "save" and then select the same location where you saved the main .EBSX file. When the download is complete, select "close". The amendment file should have a suffix "001" for amendment 1 or "002" if there are 2 amendments etc. Go to the location where you saved BOTH the main .EBSX file and the amended file and double click the icon which resembles a cube. The screen that opens should indicate the changes that were made with the amendment. Select "OK" which will then take you to an informational screen which will provide project ID, project number, amendment number etc. Then you can click on the schedule of items to verify that you have the latest schedule.

Note on Exporting and Importing in Excel Format

Because Microsoft doesn't adhere to any standardized convention for Excel file format, it was not feasible to explicitly provide an Excel Import/Export format option (contrary to what the Help Menu says). However it is still possible to export and import to Excel spreadsheets.

  • Use the CSV (default) format to export.  Excel will accept this format.
  • When you are ready to import it back to Expedite, save the file from Excel in CSV format.
  • When Excel asks "Do you want to update?” say No.
  • Import back into Expedite with the Import format spec set to CSV (default)

Note that until you are ready to send the file back to AASHTOWare Project Bids, you should save it as an Excel spreadsheet so that all of the formulas are retained.  When you save it in CSV format, the contents of the cells are converted to text.
