The IDOT Bureau of Construction subscription service for Consultants, Local Agencies, and other Departments of Transportation will allow information about updates or additions to be sent out in a more timely manner. As modifications to the manual are made they will be posted as addendum which can be viewed or downloaded from the Construction Manual Addendum page. This subscription service will provide a means to notify end users of these changes. The service is an open list; therefore, end users need to register in order to receive electronic notification of addendum. A valid e-mail address and Internet access are required to register for the service. In order to subscribe, you must fill out all required fields marked with a red asterisk.

If you have questions or problems concerning the service please contact the Central Bureau of Construction at 217/782-2760.
