CSI MasterFormat is an Industry Accepted Standard for efficient information organizing of the Project Manual, detailed cost information and related drawing notations and specifications-writing standard for most building design and construction projects in North America. It lists titles and section numbers for organizing data about construction requirements, products, and activities. By standardizing such information, MasterFormat facilitates
communication among architects, specifiers, contractors and suppliers, which helps them meet building
owners’ requirements, timelines and budgets.
