CSI MasterFormat Specifications

The Construction Specifications Institute's (CSI) MasterFormat is the most widely used standard for organizing specifications for building projects in the U.S. and Canada.

MasterFormat organizes information by work results (materials and methods) with the primary purposes of organizing specifications and detailed cost information. MasterFormat is normally used from design development on in the design construction process.
