Understanding CSI MasterFormat? What is it & how it works?

CSI MasterFormat is a tool created by the Construction Specifications Institute (CSI). It is a system used in the construction industry to prepare construction project specifications and to organize construction information. Aside from that, this tool provides a consistent organization of documents and other construction-related information.

How does CSI MasterFormat work?

The CSI MasterFormat tool consists of a list of numbers and titles that are grouped into 50 divisions. Each of these divisions covers different aspects of construction projects, such as concrete, plumbing, masonry, etc. Each of these divisions is further divided into subcategories or sections, providing more specific information.
