UniFormat is a standardised classification system that organises building information by functional elements and systems—like foundations, walls, heating systems, and site work.
It’s different from other classification methods because it focuses on how building components function together rather than the materials they’re made from.
As an architect, engineer, cost estimator, or construction professional, dealing with disorganised project information can lead to costly mistakes and communication issues.
When team members use different ways to classify building elements, it becomes difficult to track costs, create accurate estimates, and maintain consistent documentation across projects.
You need a reliable system to organise building information, especially during early project phases when material decisions haven’t been made yet.
UniFormat provides this structure by breaking down building elements in a consistent, function-based way that makes sense for preliminary project planning, cost analysis, and BIM implementation.

What Is UniFormat?
UniFormat divides building information into logical, physical parts starting with the broadest categories (like Shell or Services) and breaking them down into more specific elements. Think foundations, walls, and HVAC systems – all organised in a standardised way that makes sense for early project planning.
The system uses a simple letter-and-number hierarchy. Major group elements start with letters (A through G), followed by numbers for increasingly detailed breakdowns. For example, A is Substructure, A10 is Foundations, and A1010 gets specific with Standard Foundations.
This organisation method helps you:
- Structure cost estimates during schematic design
- Compare different design options easily
- Track building elements consistently across projects
- Coordinate with other team members efficiently
UniFormat works particularly well for preliminary project phases because it focuses on systems and assemblies rather than individual materials or products. This broader view helps teams make early decisions about building systems without getting bogged down in detailed specifications.
The current version, UniFormat 2010, includes:
- Major Group Elements (A-G)
- Group Elements (Level 2)
- Individual Elements (Level 3)
- Sub-Elements (Level 4)
Most design and construction professionals use UniFormat alongside other systems like MasterFormat, which handles detailed specifications later in the project. Together, they provide a complete approach to organising construction information from early planning through final construction.

What is UniFormat Estimating?
UniFormat estimating simplifies cost planning by organising estimates around complete building systems rather than individual materials.
This approach delivers more accurate preliminary budgets and makes it easier to compare different design options.
When you estimate with UniFormat, you’re looking at the bigger picture first.
Instead of counting every brick and nail, you’ll evaluate complete assemblies like “exterior walls” or “heating systems.”
This matters because early in design, you need ballpark figures and system-level decisions, not detailed material lists.
Let’s say you’re evaluating two different exterior wall systems. UniFormat estimating helps you compare their total installed costs, including associated components like insulation and finishing. This gives you a true cost comparison rather than just material prices.
The Process Works Like This:
- Break down the building into major systems
- Assign costs to each system based on historical data or current market rates
- Add up the systems to get your total building cost
- Adjust for project-specific conditions
UniFormat estimating proves especially valuable during schematic design when teams need quick, reliable cost information to guide major design decisions.
It helps catch potential budget issues early, when changes are still relatively easy and inexpensive to make.
What Is UniFormat Used for?
UniFormat organizes and standardizes building information during the planning and design phases of construction projects. Its practical applications extend across several key areas of project development.
Early-Stage Cost Estimation
Project teams use UniFormat to develop preliminary budgets before detailed specifications exist. This helps evaluate different design approaches and present clear cost information to project owners. Cost estimates organized by UniFormat make it straightforward to spot potential budget concerns during early design phases, when adjustments are less expensive to implement.
Project Organization
Construction projects involve architects, engineers, contractors, and owners – each with their own way of organising information.
UniFormat provides a standard structure they can all follow. When teams share drawings, specifications, or cost data, this common organisation system reduces confusion and helps maintain consistency across project documents.
Design Development and BIM Integration
During design development, teams use UniFormat to track building systems and their associated costs.
In BIM projects, this organisational structure helps manage model elements and coordinate information between different software tools. The system-based approach matches well with how buildings are actually designed and constructed.
Facilities Management
Building owners and facility managers use UniFormat to organise maintenance records and track building components.
This structured approach helps plan maintenance schedules and understand long-term operating costs. When renovation or upgrade projects come along, having building information organised by UniFormat makes it easier to scope and budget the work.
Quality Control
UniFormat helps teams check that all necessary building systems are included in the design and budget.
Breaking down the building into clear categories makes it easier to review documents for completeness and coordinate between different project requirements.
The system works effectively because it matches how buildings are put together, making it practical for both design and construction teams to use throughout the project lifecycle.
Each team can find the information they need without having to reorganise it for their specific purposes.
What Are the Benefits of UniFormat?
UniFormat’s standardised approach to organising building information delivers practical advantages throughout your project lifecycle.
From initial planning through construction and building operations, these benefits help teams work more efficiently while maintaining better project control.
- Save Time on Estimates: Create preliminary budgets faster and spend less time reorganising information. UniFormat’s standardised categories mean you can pull together cost data quickly and move forward with confidence in your numbers.
- Reduce Communication Errors: Work from the same framework across all teams. When architects, contractors, and owners share a common language for building elements, it prevents costly misunderstandings and keeps projects running smoothly.
- Make Smarter Design Decisions: Compare different building systems with consistent cost breakdowns. Understanding the full impact of design choices helps teams select the right materials and construction methods for their budget and requirements.
- Catch Problems Early: Track costs systematically from the beginning. Identifying potential budget concerns during early design phases means less expensive adjustments and fewer surprises during construction.
- Manage Buildings Better: Access organised information throughout the building’s life. Whether planning maintenance, making renovations, or tracking building performance, UniFormat’s structure helps facility managers work more effectively.
These benefits stem from UniFormat’s practical, systematic approach to organizing construction information. Whether you’re designing, building, or managing facilities, this standardised structure helps deliver better project outcomes with less effort.
What Are the Level 1 Categories in UniFormat?
Level 1 categories in UniFormat represent the major building elements found in every construction project. These categories form the foundation of the classification system and provide the primary structure for organising building information.
- A – Substructure: All the below-grade building elements, including foundations, basement walls, slabs, and excavation work that support your building from the ground up.
- B – Shell: The exterior enclosure system, including the structural frame, exterior walls, windows, doors, and roofing that create a weather-tight building envelope.
- C – Interiors: The interior construction components, including partitions, doors, floor finishes, wall finishes, and ceiling systems that create functional indoor spaces.
- D – Services: The building systems, including HVAC, plumbing, electrical, fire protection, and communications, that make the building operational and comfortable.
- E – Equipment & Furnishings: The fixed and integrated equipment, including built-in cabinetry, specialised equipment, and furnishings that support building functions.
- F – Special Construction & Demolition: The unique construction requirements, including specialty rooms, equipment, and any demolition work needed for the project.
- G – Building Sitework: The exterior improvements include site preparation, utilities, paving, landscaping, and site amenities outside the building footprint.
These Level 1 categories create a consistent framework for organising building information, helping teams coordinate effectively throughout the project lifecycle.
What is an Example of UniFormat?
The best way to understand UniFormat is through everyday examples we see in construction projects. Think of a simple coffee shop construction project.
When architects and contractors work on this building, they use UniFormat to organise every part of the construction process.
Starting from the ground up, the coffee shop’s concrete foundation falls under UniFormat’s “A10 Foundations” category.
This includes everything that supports the building from below ground. As construction moves upward, the exterior walls and roof that protect customers from weather are classified under “B10 Shell.”
Inside the coffee shop, all the interior walls, flooring, and ceiling work falls under “C10 Interior Construction.”
But UniFormat isn’t just about categorising building parts.
When using BIM software like Revit, these categories help organise the entire design process. For example, when an architect places a wall in their design, UniFormat helps them specify whether it’s an exterior wall (part of the Shell) or an interior partition.
This simple categorization makes a big difference when estimating costs or ordering materials.
Taking another example, consider a typical house construction project.
The concrete foundation that supports your house belongs to Category A (Substructure). The exterior walls, windows, and roof that protect you from the elements are part of Category B (Shell).
Inside the house, the walls separating rooms, along with flooring and ceiling finishes, fall under Category C (Interiors). Building services like plumbing and electrical systems are grouped in Category D, while built-in equipment and fixtures belong to Category E.
This systematic organisation helps everyone involved in construction speak the same language.
When a contractor sees “B2010 Exterior Walls” in the project documents, they know exactly what elements they’re responsible for, whether it’s brick walls, window installations, or exterior finishes.
This clarity helps avoid confusion and keeps projects running smoothly from design through construction.
For professionals using AutoCAD or Revit, understanding these UniFormat examples means better-organised drawings, more accurate cost estimates, and clearer communication across the entire project team.
It’s a practical tool that brings order to complex construction projects, ensuring nothing gets overlooked in the process.
What Is UniFormat II?
UniFormat II is an updated version of the original UniFormat system.
It was created by CSI (Construction Specifications Institute) and CSC (Construction Specifications Canada) to make building classification better and more detailed than the old version.
UniFormat II adds more specific categories to handle new building technologies and systems.
It still uses the same A to G main groups but breaks them down into more detailed subgroups. This helps construction teams track and organise building parts more accurately, especially when using BIM software like Revit or AutoCAD.
The new version is better at handling modern building needs, like green building materials and sustainable systems. It also works better with today’s cost estimation software, making it easier to predict and track project costs.
UniFormat vs MasterFormat
UniFormat organises building parts by their physical location and function—like foundations, walls, or roofs. It’s useful for early project planning and cost estimates.
MasterFormat organises construction work by the type of job that needs to be done – like concrete work, electrical work, or plumbing. It’s mainly used during construction to organise detailed specifications and work contracts.
Here’s the main difference: UniFormat focuses on “what” parts make up the building, while MasterFormat focuses on “how” these parts will be built. For example:
- In UniFormat, an exterior wall is grouped under “Shell” because that’s where it is in the building
- In MasterFormat, the same wall is split into different work sectors like masonry, insulation, and painting because that’s how it gets built
Architects and cost estimators often use UniFormat early in projects. Contractors and builders use MasterFormat more during actual construction to organise their work and materials.
