What is OmniClass®?

OmniClass® is a comprehensive classification system that covers all aspects of the construction industry. It provides a standardized way to organize information throughout the entire building lifecycle, from initial design through operation and maintenance.

Key Benefits

  • Comprehensive industry coverage
  • BIM integration capabilities
  • Lifecycle information management
  • Cross-phase project coordination
  • Industry-wide data standardization

Common Applications

  • BIM object classification
  • Database organization
  • Project coordination
  • Information management systems
  • Industry data exchange

OmniClass® Tables

OmniClass® consists of 15 tables that classify different aspects of construction information:

Table 11 - Construction Entities by Function

Buildings and infrastructure by their primary function

Table 12 - Construction Entities by Form

Buildings and infrastructure by their physical form

Table 21 - Elements (UniFormat)

Building elements organized by function

Table 22 - Work Results (MasterFormat)

Construction work organized by work results

Table 23 - Products

Construction products and materials

Table 31 - Phases

Project phases from conception to demolition

BIM Integration with OmniClass®

Building Information Modeling (BIM) relies on standardized classification to organize and manage complex building data. OmniClass® provides the comprehensive framework needed for effective BIM implementation.

BIM Object Classification

Every BIM object can be classified using multiple OmniClass® tables to capture its function, form, material properties, and lifecycle phase.

Data Interoperability

Standardized classification enables seamless data exchange between different BIM software platforms and project stakeholders.

Implementation Strategy

1. Assess Your Needs

Determine which OmniClass® tables are most relevant to your organization and projects.

2. Start with Core Tables

Begin implementation with the most commonly used tables (21, 22, 23) before expanding to specialized classifications.

3. Train Your Team

Provide comprehensive training on OmniClass® structure and application across different project phases.

4. Integrate with Systems

Implement OmniClass® classifications in your BIM software, databases, and information management systems.
