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.*

As of July, 30th 2020, given the implementation of the CSI CROSSWALK  API in the HPD Builder, manufacturers can now use the CSI MasterFormat Classification Search function to find the right CSI Section for their products.  

Please link to the documentation below to learn more about the background of the MasterFormat Classification Search and Instructions for using this new HPD Builder feature.
