IE Browser Tip: Use the right mouse button, then "Save Target As" when downloading individual CBID files. Using the left mouse button attempts to run/open the file and could cause system errors.

CBID files contain the pay items and quantities for a contract, as well as macros to prepare and print a bid. These files are in Excel 97 v4.0 (xls).

Please review the instructions carefully before using CBID files to prepare your bid.

CBID files are put on the Website as they become available. If the contract you want is not yet on the list, please check back at a later date.

Note that the CBID filename is the same as the IDOT Contract Number. Please refer to the Transportation Bulletin - Notice of Letting for the correct contract number.
