Why Do You Need Documentation Certification?

Documentation certification (IDOT Class S-14) is required for all consultants to become prequalified with IDOT to perform construction inspection (Phase III) work. Construction Inspection consists of staking, material testing and inspection, documentation of materials and quantities, record keeping and enforcement of specifications applicable to a contractor’s work on construction projects. For a complete list of requirements for consultant prequalification, visit the Consultant Prequalification web page.

The purpose of this class is to provide the student with the ability to document contract quantities in compliance with state and federal standards. This class will cover project diary entries, quantity book preparation, cross-reference system, extra work reports, measurement and calculation of pay items for pay quantities occurring in road and bridge plans.

The three-day Documentation of Contract Quantities class and retests are administered by the Illinois Center for Transportation (ICT).

How to Become Certified

RECOMMENDED FOR CLASS: One year IDOT construction experience, familiarity with general highway and IDOT construction terminology and practice, and knowledge of basic algebra and geometry including Order of Operations and the ability to calculate areas and volumes. Links to math refresher web pages are provided in the menu to the right.

To obtain Documentation Certification, one must successfully pass the test given during the Documentation of Contract Quantities class. A passing score is 70% or greater, and the certification is valid for 4 years. A person currently certified can just take the 2-hour Documentation Exam (re-test) within 4 months of expiration to re-certify without retaking the class. Once a certificate has expired by more than 4 months, the individual must attend the class to become certified again. It is each individual’s responsibility to remember to re-test close to the expiration date. No exceptions will be made.

All class exams and re-test exams are OPEN BOOK/OPEN NOTES. Any printed materials may be used during the exams. No electronic devices beyond the standard scientific calculator are allowed during the exams. (No cell phones, tablets, computers, cameras, other recording devices etc.)

Individuals who do not obtain a passing score at class are allowed to re-test one time by registering for a re-test day and paying the associated fee. If they are not successful after the re-test attempt to obtain certification, they must re-attend the Construction Documentation of Contract Quantities 3-day class by registering for a 3-day class and paying the associated fee. The Illinois Center for Transportation has several re-test dates scheduled December through May. Requests for individual test dates will not be accepted.
