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
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.
