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 Technology (CDT®) program, 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

CSI's CDT® program has provided foundation training in construction documentation for architects, contractors, contract administrators, specifiers, and manufacturers' representatives for decades.
