ASTM E1557-05

Standard Classification for Building Elements and Related Sitework-UNIFORMAT II

SCOPE
1.1 This standard 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. presents a more detailed suggested Level 4 classification of sub-elements.
1.4 UNIFORMAT II is an elemental format similar to the original UNIFORMAT 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.
