Crosswalk in practice

Three standards.
Connected from design to delivery.

Each standard organizes construction information differently. Crosswalk® connects related classifications so you can carry context from early planning into specifications, construction, and handover.

MasterFormat®

What it organizes

Specifications and construction work results.

How Crosswalk helps

Connect detailed work to related building elements and product classifications when coordinating specifications, estimates, and scopes of work.

UniFormat®

What it organizes

Building elements, systems, and assemblies.

How Crosswalk helps

Explore related work results as early design and elemental estimates develop into detailed construction documentation.

OmniClass®

What it organizes

Information about the built environment, including products and work results.

How Crosswalk helps

Review related classifications while coordinating product, project, and facility information through construction and handover.

Crosswalk questions, answered.

How do I access Crosswalk in the CDS Platform?

Select Get started to sign up and purchase access to CSI Dynamic Standards. Then sign in to the CDS Platform with the same account. Open a classification, find Crosswalks, and select a related classification to open it in a new tab.

Are Crosswalks one-to-one matches?

Not necessarily. One classification may relate to several classifications in another standard, and several classifications may relate to one classification.

How do I compare related classifications?

Confirm the source and related standards and editions. Compare classification titles and available explanatory fields, then review the parent and child context on both sides. Keep the source record open while exploring related classifications.

Are Crosswalks and Transitions the same?

Crosswalks connect related classifications across different CSI standards. Transitions support changes between editions of the same standard, including MasterFormat 2020 to MasterFormat 2026.
