It is the contractor's responsibility to determine which, if any, addenda pertains to any project they may be bidding. Failure to incorporate all relevant addenda may cause the bid to be declared unacceptable.  Each addendum will be placed with the electronic Plan and/or Proposal. Addenda will also be placed on the Addendum Checklist and subscription service subscribers will be notified by e-mail of each addendum issued.  The Internet is the Department's primary way of doing business. The subscription server e-mails are an added courtesy the Department provides. It is suggested that bidders review this page before submitting final bid information.

IDOT is not responsible for any e-mail related failures.

Questions may be directed to Jim Layden at 217-782-7806 or
