The Documentation of Contract Quantities & Appendix Guide (or "Documentation Guide" for short) contains policies which represent the minimum documentation requirements for use by construction personnel for proper documentation of day to day events as well as contract pay quantities on the state's highway construction projects.  The Synopsis & Workbook contains the documentation of contract quantities synopsis and a workbook with example problems including solutions.  Each IDOT district may require additional documentation due to conditions specific to the District.

The CMMS Supplement – Documentation of Contract Quantities Guide document serves as a supplement to the department’s Documentation of Contract Quantities Guide. This supplement is intended for use when the Construction and Materials Management System (CMMS) is being utilized to administer a construction contract.

Highway Standards show the details of various construction items and are used in conjunction with the Standard Specifications.  The applicable Standards are referenced on the cover sheet of the plans. To view the most current DGN files please navigate to Highways Standards.

IDOT's Bureau of Local Roads and Streets publishes and maintains a manual which establishes uniform policies and procedures for the location, design, and environmental evaluation of highway construction projects on the local highway system. The purpose of this policy is to compile the policies and procedures which govern project location, design, and environmental evaluation into one comprehensive manual.

As of January 1, 2006, all design approvals will be based on the most current electronic version of this manual unless a variance is granted.

All materials used on a project must have evidence of materials inspection, in other words, there must be proof that the materials incorporated into the work meet specification. IDOT's Bureau of Materials is used as a resource for determining reasonable inspection procedures and sampling frequencies for materials used in highway construction. This guide seeks to establish materials sampling and testing uniformity throughout the state by providing sampling schedules which list the minimum frequencies at which samples and measurements shall be taken by project, plant, and IDOT's district personnel.

This guide applies to all projects constructed on the state system and all local agency improvement projects with federal, state, or MFT funds. Specific exceptions to this Manual for Local Agency work are indicated in the current Local Roads and Streets Manual(s) or by circular letter.
