CSI MasterFormat

 

For anyone new to construction, it seems like we speak a different language. We’re always referring to a division, section, or title to communicate during the design and construction.  Sooner or later your start to hearing about something called CSI MasterFormat. 

 

But when did all of this start? Who standardized the way we refer to documents? With a little reading, here’s what I learned.

 

In the first half of the 20th century, construction projects had no consistency from project to project. A California project might specify concrete in Section 8A, while in Texas, Section 32 defines the same scope. Locating information was troublesome and time-consuming for the entire industry.

 

To solve the challenge of consistency, a group of engineers who worked for various US government agencies in 1947 began meeting informally to discuss how to create a more uniform specification system. A better way of creating consistency and specifying work results and construction requirements was their focus.

 

Construction Specifications Institute (CSI)

 

The engineer’s informal meetings grew into what we know today as the Construction Specifications Institute (CSI) in 1948. An industry-wide organization with a primary goal of advancing specifications and developing a systematic approach to organizing construction documents and standardizing forms.

 

In 1963, CSI MasterFormat was released, a numbering system with titles for organizing construction information into 16 Divisions and a five-digit numbering system called Sections, and a standard way of organizing the information and the communication we all use today.

 

Today, many of us refer to MasterFormat as the “Dewey Decimal System” of organizing specifications. It promotes standardization, facilitates retrieval of information, and improved communication among all parties involved in construction projects.

 

So the next time you work on a project and start referring to the divisions, section numbers, and titles, remember it was a group of engineers that set in motion the standard communication we use today.

 

CSI MasterFormat Divisions (Current) 

 

In 2004, CSI MasterFormat was updated to 50 Divisions and expanded the numbering sequence (Sections) to a six-digit numbering sequence to continue CSI MasterFormat’s growth. The expansion’s primary reason was to address overcrowded divisions and additional divisions to include infrastructure and process equipment. The numbering sequence (Sections) and titles are updated roughly every two years. Check out a recent edition of CSI MasterFormat at this link.
