Letting Specific Items
BDE Special Provisions
IDOT’s Bureau of Design and Environment (BDE) issues the BDE Special Provisions four times a year. They are inserted into contracts as they apply. Please navigate to the BDE Special Provisions webpage for a listing of these materials.
Coded Pay Items
The Coded Pay Items are updated seven times each year. Each updated codebook corresponds with a regularly scheduled IDOT Letting. If a Special Letting is held, the most recent update prior to the Special Letting should be used.
