Construction Inspector Certification Program

About the Program

This program was created by CDOT in 2004 to develop a qualified inspection staff in order to obtain a higher-quality end product on the highway. There are three categories of inspector exams:

  • basic highway math
  • basic construction surveying
  • basic highway plan reading

All construction inspectors—whether from CDOT or a consultant—must demonstrate proficiency by passing an exam and earning certification within the developed categories. CDOT has developed self-study manuals for four of the entry-level certification courses. 

Cost & Payment Information
