MasterFormat is a standard for organizing construction specifications that is widely used in the United States and Canada. It is published by the Construction Specifications Institute (CSI) and the Construction Specifications Canada (CSC). The most recent edition of MasterFormat is the 2020 edition, which was released in December 2019. It includes 50 divisions that cover a wide range of construction work, including building materials and systems, finishes, equipment, and specialties. The divisions are organized hierarchically, with each division being divided into sections that cover specific types of work or materials. The organization of the divisions and sections in MasterFormat is designed to be flexible and adaptable to the needs of different construction projects.
Each division is further divided into sections that cover specific types of work or materials. The sections within each division are numbered sequentially, and the numbers are preceded by the division number. For example, Section 03300 – Cast-in-Place Concrete is part of Division 3 (Concrete). The section numbers and titles in MasterFormat are intended to be used as part of a comprehensive construction specification system, and they are intended to provide a common language for organizing and communicating construction information.
