The Construction Documents Technology (CDT) Program provides a comprehensive overview for anyone who writes, interprets, enforces, or manages construction documents. Project architects, contractors, contract administrators, material suppliers, and manufacturers' representatives are all realizing the advantages of being Construction Documents Technologists.

By being able to understand and interpret written construction documents, CDTs perform their jobs more effectively. By understanding the roles and relationships of all participants, CDTs improve communication among all members of the construction team.

Pass the Construction Documents Technologist Exam (CDT), and you'll join an elite group of professionals known in the industry for their comprehensive knowledge of the writing and management of construction documents. Getting your CDT means:

  • Adding "CDT" after your name, to your business card and to your resume
  • Understanding how a project unfolds from conception to delivery
  • Understanding the documentation involved
The CDT certificate is a prerequisite to CSI's advanced certification exams: Certified Construction Specifier (CCS), Certified Construction Contract Administrator (CCCA), or Certified Construction Product Representative (CCPR) certification.
