License UniFormat® Standards
Get your official UniFormat® license from CSI. The essential classification system for organizing building elements by function.
What is UniFormat®?
UniFormat® classifies building elements by their function rather than by materials or construction methods. This approach makes it ideal for early design phase cost estimation and building element lifecycle tracking.
Key Benefits
- Function-based organization
- Early design cost estimation
- Comparative cost analysis
- Building element lifecycle tracking
- Performance-based specifications
Common Applications
- Conceptual cost estimates
- Design development budgeting
- Building performance analysis
- Facility management systems
- Asset lifecycle planning
UniFormat® vs MasterFormat®
UniFormat® - By Function
- A10 Foundations
- B10 Superstructure
- C10 Interior Construction
- D20 Plumbing
- E10 Equipment
MasterFormat® - By Work Result
- 03 Concrete
- 05 Metals
- 07 Thermal & Moisture Protection
- 09 Finishes
- 22 Plumbing
Key Difference: UniFormat® groups by what the element does (function), while MasterFormat® groups by how it's constructed (work result).
UniFormat® Structure
UniFormat® organizes building elements into major groups:
A - Substructure
Foundations, basement construction, and below-grade elements
B - Shell
Superstructure, exterior enclosure, and roofing systems
C - Interiors
Interior construction, stairs, and interior finishes
D - Services
Conveying, plumbing, HVAC, fire protection, and electrical systems
E - Equipment & Furnishings
Equipment, furnishings, and special construction
When to Use UniFormat®
Design Phase
Ideal for early design cost estimation when specific materials and methods haven't been determined yet.
Cost Analysis
Perfect for comparing costs between different building types and analyzing functional performance.
Asset Management
Essential for tracking building element lifecycles and planning maintenance schedules.
