life cycle and maintenance information into the classification. With this expansion, MasterFormat was positioned to help facilitate Building Information Modeling (BIM) to contain project specifications. The MasterFormat standard serves as the organizational structure for construction industry publications such as the Sweets catalog with a wide range of building products, and master guide specification products such as MasterSpec and BSD SpecLink. MasterFormat helps architects, engineers, owners, contractors, and manufacturers classify the construction of work results using a variety of construction resources. The MasterFormat sections within the Divisions can also be used to reference performance and safety requirements generated by agencies such as the American Society for Testing and Materials (ASTM) and the Occupational Safety and Health Administration (OSHA), among others. UniFormat UniFormat is a construction classification system organized by functional elements in a construction project. Functional elements are defined as "constituent parts of a construction entity with a characteristic function, form, or position." Unlike the content of MasterFormat, most content in UniFormat is described without reference to specific means of achieving the function the element serves. The first edition of UniFormat was published by CSI in 1992. New and revised editions of UniFormat were published by CSI in 1998 and 2010. Titles in UniFormat Levels 1 through 3 can be applied to most project descriptions and preliminary cost estimates. Levels 4 and below provide a more detailed breakdown of the functional elements. SectionFormat/PageFormat SectionFormat provides a standard arrangement of construction specification sections into three parts: Part 1 General, which includes administrative and procedural requirements unique to the section, expanding on subjects covered in Division 01 and adding information unique to the section. Part 2 Products, which describes the systems, assemblies, equipment, products, materials, fabrications, and mixes that are to be incorporated into the project. Part 3, Execution, which includes requirements for field/site installation or application, including preparatory actions and post-installation cleaning and protection. This arrangement of specification section information is otherwise known as “three-part format” and is expected and commonplace throughout the North American construction industry. CSI first published SectionFormat in 1969, the most current edition was published in 2008. PageFormat provides a recommended style guide for presenting the titles and content of construction specifications sections as described by SectionFormat. CSI first published PageFormat in 1975. SectionFormat and PageFormat were published as separate publications until the 2008 edition, when they were combined into a single publication GreenFormat CSI's GreenFormat is a
