Documentation of Contract Quantities

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 class 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.

To obtain documentation certification, one must successfully pass the test administered during the Documentation of Contract Quantities’ full class with a score of 70 percent or higher. Once a passing test score is obtained, certification is valid for four years.

In the event a passing score is not obtained, full class attendees may choose to either take a retest or retake the
full class by registering online and paying the associated fee. Only one retest attempt is allowed after failing a full- class exam. The retest must occur within one calendar year of the full class exam date.

If one fails to pass a retest exam, then he or she must take the full class in order to attempt the exam again.

Certified individuals have a four-month grace period following the expiration of their certification. Before the end of the grace period, attendees have one opportunity to recertify by registering online and paying the associated fee, taking a two- and-a-half-hour documentation exam (retest) and passing with a score of 70 percent or higher.

If certification expires by more than the allotted four-month grace period or the attendee does not pass the retest, the individual must retake the full class in order to attempt the exam again. Once a passing test score is obtained, the individual will again be certified.

Note: It is each individual’s responsibility to remember to retest within the four-month grace period of his or her certification expiration date. No exceptions.
