1.1本标准规定了建筑构件和相关现场工程的分类。如本文所定义，图元是大多数建筑常见的主要构件。无论设计规范、施工方法或使用的材料如何，构件通常执行给定的功能。该分类可作为建筑物可行性、规划和设计阶段分析、评估和监测的一致参考。使用UNIFORMAT II可以确保建筑项目在一段时间内以及项目之间的经济评估的一致性。它还加强了施工各个阶段的报告，从可行性和规划到工作文件的编制、施工、维护、修复和处置。 1.2本分类适用于建筑物和相关现场工程。 它不包括与建筑物功能用途相关的专业工艺设备，但包括家具和设备。 1.3分类包括三个层次，分别为1、2和3级。提出了更详细的建议的子元素4级分类。 1.4 UNIFORMAT II是一种基本格式，类似于原始UNIFORMAT元素分类。然而，UNIFORMAT II与原始UNIFORMAT的不同之处在于，它考虑了更广泛的建筑类型，并已更新为按当前建筑实践对建筑元素进行分类。

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.
