Electronic Bidding Instructions


The New York State Thruway Authority (NYSTA) uses AASHTOWare Project Bids software for electronic bidding. Electronic bid files are in proprietary format (*.ebsx). Bidders must use the free module called Project Bids BID to view this data and generate the appropriate bid sheets and electronic file for submission to the Authority. 

The Authority’s adoption of electronic bidding does not force any Contractor to bid electronically.  Rather, participation is voluntary.  If submitting a bid using infotech’s Bid Express internet bidding service no paper is required.  If submitting an electronic bid on a CD, DVD or USB device delivered to the Authority in person or via a courier service, bidders must also submit print outs that match the electronic file.  Project Bids prints a check code on every bid page that must match the check code in the computer file.  As the check code changes every time the electronic file is modified, matching the codes verifies that the data on the printed bid is the same as in the electronic file.  In case of discrepancy, the printouts always prevail and are the primary legal document.  Therefore the printouts can be used to make any last minute changes.

The electronic bid file will be posted to NYSTA's website to coincide with a contract’s initial advertising. Electronic bid amendment files will be posted whenever amendment notices are posted. These must be applied to the original electronic bid file.

Do not bid without carefully reviewing the proposal and any and all changes by amendment.  Proposal notes and circumstances include, but are not limited to, information on alternate, fixed and/or limited cost items and/or special circumstances regarding item placement and use.  Contractors are solely responsible for recognizing and properly responding to any and all special notes and circumstances in the Contract Proposal and any and all changes by amendment from the amendment documents and/or notices communicated to them by NYSTA’s Office of Capital Program and Contracts Management.

Please be certain to review the rest of this page and its links before attempting to use Project Bids and/or data obtained from our Contract Documents section.  Failure to thoroughly review and comply with the requirements of the Authority's Project Bids program may result in serious errors or omissions in your bid.
