CSI CDT case studies

CSI CDT · Put your knowledge to work in context.

The Construction Documents Technologist (CDT®) is a certification offered by the Construction Specifications Institute (CSI) that, in CSI's words, "gives you the skills and confidence to interpret, organize, and communicate construction information clearly-no matter your role on the project team." CSI describes itself as "the construction community's authority on communication and construction documentation," and frames the CDT as proof of a comprehensive understanding of how to effectively interpret and communicate construction documentation. The credential is aimed at a broad slice of the AECO industry rather than a single job title. The CSI CDT case studies are 5 cases and about 2,534 words.
