CSI MasterFormat and Division 07: principles and terminology

What the MasterFormat list is, how its numbers are built, where fabricated and manufactured flashing sit in Division 07 as the 2018 list prints it, and why Division 01 procedures matter to a fabricator.

You will be able to: Define MasterFormat, read a six-digit section number, locate sheet metal flashing and its neighbours in Division 07, and name what Division 01 does for a section that points to it.

What MasterFormat does

Construction Canada calls MasterFormat a hierarchical classification system: a standard set of numbers and titles for the subjects in a construction specification.

CSC and CSI created it; it grew out of the Building Specifications Index. It numbers and titles subjects. The requirements themselves are written in a project's own specification sections.

Glossary

MasterFormat
A hierarchical classification system from CSC and CSI: a standard set of numbers and titles for the subjects in a construction specification, grouped into divisions 00 to 49.
Division
The top-level group in MasterFormat, shown by the first two digits. Division 07 is Thermal and Moisture Protection and Division 01 is General Requirements.
Section
One numbered subject, such as 07 62 00 Sheet Metal Flashing and Trim. In a project, the section is the written specification text for that subject.
Decimal extension
A decimal extension after the six digits, as in 07 95 13.13 Interior Expansion Joint Cover Assemblies, that adds a more specific title under a six-digit number.
Fabricated versus manufactured
The list's own split: 07 62 xx titles say Fabricated (shop and field-formed) and 07 71 xx titles say Manufactured, so the same piece, such as a coping, has a number in each.
Division 01
General Requirements: the administrative and procedural sections, including submittal procedures, quality assurance and control, and closeout, that sections commonly point to (UFGS and VA flashing sections do; the utility section used in this module does not).
