Download OmniClass for Infrastructure

OmniClass provides lifecycle classification you can compute on—tag models, submittals, and assets so closeout is owner-ready and FM systems ingest data cleanly, keeping design, construction, and operations aligned.

Infrastructure projects—transportation, utilities, water, energy—use CSI classifications alongside agency-specific standards for specifications, cost tracking, and asset management.

Long-duration infrastructure projects span multiple edition releases. Assets that operate for 50+ years need classification that connects original design to decades of operations.

Why OmniClass Matters Here

Buildings operate for decades. If the classification applied during design and construction doesn't carry into operations, owners and FM teams rebuild taxonomy from scratch—wasting the structured data that already exists.

Accessing OmniClass through The Construction Standard means working with CSI Dynamic Standards—always-current, edition-aware data you can search, cross-reference, and integrate—not a static PDF that's outdated the moment a new edition releases.

What Changes With CSI Dynamic Standards

CSI Dynamic Standards includes OmniClass tables that cover every aspect of the built environment: building elements, spaces, work results, products, and phases. Licensed through The Construction Standard, tags applied during design flow through construction into CMMS, CAFM, and digital twin platforms.

Static downloads lose their value as standards evolve. CSI Dynamic Standards includes OmniClass as part of a living, connected system—with edition tracking, governed crosswalks, and cross-references. The Construction Standard provides licensed access.

How the Standards Connect

OmniClass cross-references to both MasterFormat and UniFormat, providing the comprehensive lifecycle layer that connects specification-phase organization to operations-phase asset management.

Edition-aware, lifecycle-classified standards keep infrastructure documentation current across decades-long operational lifespans and multiple capital improvement cycles.

The Licensing Relationship

CSI—the Construction Specifications Institute—stewards and governs MasterFormat, UniFormat, and OmniClass. CSI Dynamic Standards includes all three as a connected, edition-aware system. The Construction Standard provides licensed access to CSI Dynamic Standards. That means:

• Always current: Numbers, titles, and classifications reflect the latest CSI-approved updates
• Edition-aware: Teams know which edition applies at each milestone and what changed
• Cross-referenced: Governed relationships between MasterFormat, UniFormat, and OmniClass stay maintained
• Integration-ready: Enterprise solutions carry standards data into the tools you already use
