About CSI Crosswalk

Classifying building data can be a challenge, especially in critical handoffs between building phases, and between different versions of key standards. CROSSWALK provides immediate access to CSI MasterFormat®, including past versions back to 1995, and allows you to cross reference classifications made in MasterFormat, Uniformat®, and OmniClass® to Uniformat and OmniClass, all through an enterprise-grade API. Brought to you by CSI, the creator of construction standards, CROSSWALK is the digital engine for the Architecture, Engineering, Construction, and Owner (AECO) community, driving plans, protocols, and performance across the lifecycle of a construction project.
