Standard Classification for Building Elements and Related Sitework—UNIFORMAT II

SIGNIFICANCE AND USE
4.1 This classification defines building elements as major components common to most buildings. The classification is the common thread linking activities and participants in a building project from initial planning through operations, maintenance, and disposal.  
4.2 The users of UNIFORMAT II include owners, developers, facilities programmers, cost planners, estimators, schedulers, architects and engineers, specification writers, operating and maintenance staff, manufacturers, and educators.  
4.3 Use this classification when doing the following:5  
4.3.1 Structuring costs on an elemental basis for economic evaluations (Practices E917, E964, E1057, E1074, E1121, and E1804) early in the design process. Using UNIFORMAT II helps reduce the cost of early analysis and contributes to substantial design and operational savings before decisions have been made that limit options for potential savings.  
4.3.2 Estimating and controlling costs during planning, design, and construction. Use UNIFORMAT II to prepare budgets and to establish elemental cost plans before design begins. The project manager uses these to control project cost, time, and quality, and to set design-to-cost targets. See Appendix X2 for an example of a UNIFORMAT II building elemental design cost estimate.  
4.3.3 Conducting value engineering workshops. Use UNIFORMAT II as a checklist to ensure that alternatives for all elements of significant cost in the building project are analyzed in the creativity phase of the job plan. Also, use the elemental cost data to expedite the development of cost models for building systems.  
4.3.4 Developing initial project master schedules. Since projects are built element by element, UNIFORMAT II is an appropriate basis for preparing construction schedules at the start of the design process.  
4.3.5 Performing risk analyses. Simulation is one technique (Practice E1369) for developing probability distributions of building costs when evaluating the economic risk in u...
SCOPE
1.1 This classification establishes a classification of building elements and related sitework. Elements, as defined here, are major components common to most buildings. Elements usually perform a given function, regardless of the design specification, construction method, or materials used. The classification serves as a consistent reference for analysis, evaluation, and monitoring during the feasibility, planning, and design stages of buildings. Using UNIFORMAT II ensures consistency in the economic evaluation of buildings projects over time and from project to project. It also enhances reporting at all stages in construction—from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.  
1.2 This classification applies to buildings and related site work. It excludes specialized process equipment related to a building’s functional use but does include furnishings and equipment.  
1.3 The classification incorporates three hierarchical levels described as Levels 1, 2, and 3. Appendix X1 presents a more detailed suggested Level 4 classification of sub-elements.  
1.4 UNIFORMAT II is an elemental format similar to the original UNIFORMAT2 elemental classification. UNIFORMAT II differs from the original UNIFORMAT, however, in that it takes into consideration a broader range of building types and has been updated to categorize building elements as they are in current building practice.  
1.5 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM E1557-09(2020)e1: Standard Classification for Building Elements and Related Sitework-UNIFORMAT II is an internationally recognized standard published by ASTM International. This classification system establishes a comprehensive elemental structure for buildings and related sitework, widely known as UNIFORMAT II. It defines major components common to most buildings, organizing construction information into hierarchical levels to support cost management, planning, design, and analysis throughout a building's lifecycle-from feasibility and programming to construction, use, maintenance, and disposal.

Key Topics

• Elemental Classification Structure: UNIFORMAT II uses a tiered (Levels 1, 2, and 3) approach to break down buildings and sitework into major groups, group elements, and individual elements. This facilitates consistent documentation, cost tracking, and analysis.
• Lifecycle Application: The classification assists during all stages-planning, design, construction, operation, maintenance, renovation, and demolition-ensuring continuity in information and reporting.
• Cost Management: By structuring cost data according to building elements rather than trade-specific categories, UNIFORMAT II enables accurate budgeting, early cost planning, and comprehensive life-cycle analysis.
• Value Engineering and Risk Analysis: The standard serves as a framework for conducting value engineering workshops, developing master schedules, and performing economic risk assessments.
• Sitework Integration: Site-related construction components, such as landscaping, utilities, and site development, are included to ensure a holistic approach to project classification.
• Standardization and International Application: Developed in compliance with international standardization guidelines, UNIFORMAT II enhances reporting and comparability across various building projects globally.

Applications

UNIFORMAT II plays a central role in the construction and facilities management industries. Practical applications include:

• Owners, Developers, and Facility Managers: Use the classification to evaluate and monitor facility investments over time, prepare strategic plans, and streamline operations and maintenance activities.
• Project and Cost Managers: Leverage elemental cost structures for preparing initial budgets, tracking project expenditures, developing schedules, and defining project scopes.
• Architects, Engineers, and Designers: Structure project documentation and preliminary descriptions, enhance design communication, and standardize design-to-cost benchmarks.
• Estimators and Value Engineers: Develop consistent cost estimates, facilitate value engineering workshops, and ensure all significant cost elements are analyzed for potential savings.
• Contractors and Subcontractors: Reference a unified classification for bid preparation and project execution, improving coordination between disciplines.
• Educators and Researchers: Provide a framework for teaching construction economics, cost planning, and building system classifications.
• Software Developers and BIM Specialists: Implement UNIFORMAT II as an organizing principle within databases, BIM models, and cost estimating tools for seamless information flow.

Related Standards

UNIFORMAT II is closely linked to a suite of ASTM standards that further support building economics, cost management, and risk analysis, including:

• ASTM E917: Life-Cycle Costing for Buildings and Building Systems
• ASTM E964: Benefit-to-Cost and Savings-to-Investment Ratios
• ASTM E1057, E1074, E1121: Economic evaluation methods (Internal Rate of Return, Payback, Net Benefits)
• ASTM E1369: Techniques for Risk Treatment in Economic Evaluations
• ASTM E2514: Format for Elemental Cost Estimates
• ASTM E2083, E2168: Field Requirements and Cost Allowances

By adopting ASTM E1557-09(2020)e1 – UNIFORMAT II, stakeholders across the construction and real estate sectors ensure standardized communication, improve project performance, and benefit from robust cost control and economic evaluation over the lifespan of a facility.
