What is a crosswalk?
Crosswalks are links between standards and related classifications. Use a Crosswalk when you have a classification in one CSI standard and want to find related classifications in another.

MasterFormat
Division 03 — Concrete
Division 31 — Earthwork
The application data connects UniFormat Substructure to related MasterFormat work in Concrete and Earthwork.
Crosswalks do not show edition upgrades. Use Transitions to understand changes from MasterFormat 2020 to MasterFormat 2026.
Are Crosswalks and Transitions the same?
No. Crosswalks connect related classifications across different CSI standards. Transitions support upgrades between editions of a standard.
