Why do I need documentation certification?

Documentation of Contract Quantities is administered by Illinois Center for Transportation offering documentation certification (IDOT class S-14).

The course is a prequalification for all IDOT consultants who will perform construction inspection (Phase III) work, including staking, material testing, inspection, documentation of materials and quantities, record keeping, enforcing specifications and much more. Check out a complete list of requirements for consultant prequalification.

The course helps attendees learn how to:

  • Properly document contract quantities in compliance with state and federal standards
  • Make project diary entries
  • Quantify book preparation
  • Use the cross-reference system 
  • Create extra work reports, measurement and calculation of pay items for pay quantities occurring in road and bridge plans.
