OmniClass Table 22: Work Results

OmniClass Table 22 – Work Results provides lifecycle classification that spans design, construction, and operations. As part of CSI's comprehensive classification system, Table 22 delivers the taxonomy that BIM models, FM systems, and construction platforms need to organize work results data authoritatively.

OmniClass Table 22 classifies work results—the outcomes of construction activities organized by the type of work performed, closely aligned with MasterFormat's specification structure.

This table classifies work results such as concrete work, masonry work, metal work, wood work, thermal and moisture protection, openings, finishes, specialties, equipment, furnishings, and all MEP system installations.

Table 22 contains a detailed, consensus-based taxonomy that organizes this scope into categories and subcategories professionals can apply across projects. These classifications provide a shared vocabulary across the construction lifecycle. When teams apply Table 22 classifications consistently, data flows cleanly from design through construction into decades of facility operations.

Licensed through The Construction Standard, CSI Dynamic Standards includes the authoritative, always-current Table 22 classifications—searchable, cross-referenced to MasterFormat and UniFormat, and edition-aware.

Table 22 work result classification applies during construction—organizing what work is performed. This classification connects to specification sections (MasterFormat), building elements (UniFormat), and the products installed (Table 23).

Who Uses Table 22

• Specifiers organizing work results by type
• Contractors tracking work completion by category
• Cost databases organizing unit cost data
• BIM coordinators classifying model objects by work result

Whether you tag BIM models, manage building assets, build construction software, or organize project data, Table 22 provides the authoritative classification that keeps your work consistent with the broader industry.

MasterFormat

Table 22 work results closely mirror MasterFormat divisions—concrete work results align with Division 03, masonry with Division 04, and so on through all specification divisions.

UniFormat

Multiple work results from Table 22 compose a single UniFormat element—a wall element (UniFormat B2010) requires masonry, waterproofing, insulation, and finish work results.

These connections are maintained by CSI through governed relationships—not assembled ad hoc by individual project teams. Through The Construction Standard, licensed access to CSI Dynamic Standards gives teams these crosswalks so they can navigate between lifecycle categories, building elements, and specification sections without manual remapping.

Why OmniClass Matters for Long-Term Value

Buildings operate for decades. The classification applied during design and construction must carry into operations, maintenance, and capital renewal. OmniClass Table 22 provides the lifecycle layer that connects design-phase decisions to operations-phase reality—ensuring that structured data doesn't lose its value at handover.

Without authoritative lifecycle classification, FM teams rebuild taxonomy from scratch. Equipment histories lose their connection to original specifications. Capital renewal budgets lack the structured data needed for systematic planning. OmniClass Table 22 prevents these disconnects by providing classification that was designed to span the full lifecycle.

The Licensing Relationship

CSI—the Construction Specifications Institute—stewards OmniClass Table 22 as part of the OmniClass standard. CSI Dynamic Standards includes MasterFormat, UniFormat, and OmniClass as a connected, edition-aware system. The Construction Standard provides licensed access to CSI Dynamic Standards:

• Always current: Classifications reflect the latest CSI-approved updates
• Edition-aware: Teams know which edition applies and what changed between releases
• Cross-referenced: Governed relationships to MasterFormat and UniFormat stay maintained
• Integration-ready: Enterprise solutions carry Table 22 data into the tools you already use
