MasterFormat®, a publication of Construction Specifications Institute (CSI) and Construction Specifications Canada (CSC), is a master list of numbers and titles classified by work results. 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.*
