MasterFormat^® 2016, a product of the Construction Specifications Institute (CSI), is a widely used standard for documenting project requirements on commercial and institutional building projects in the United States and Canada.

The MasterFormat is organized by divisions and sections. Each division addresses a different set of requirements for the construction project. Division 27 specifically addresses communications construction, providing specifications and instructions for areas such as data, voice, audio, video, cabling, enclosures, grounding and bonding. Division 26 addresses electrical construction and covers areas such as cable tray and industrial enclosures.
