Construction Management is a professional service that applies effective management techniques to the planning, design, and construction of a project from inception to completion for the purpose of controlling time, cost and quality. Construction Management is a discipline and management system specifically created to promote the successful execution of capital projects for owners. These projects can be highly complex. Few owners maintain the staff resources necessary to pay close, continuing attention to every detail–yet these details can “make or break” a project.

CSI was founded in March 1948 by the specification writers of government agencies who came together to improve the quality of construction specifications.
