1、Designation: E1557 09 (Reapproved 2015)Standard Classification forBuilding Elements and Related SiteworkUNIFORMAT II1This standard is issued under the fixed designation E1557; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the yea
2、r of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification establishes a classification of buildingelements and related sitework. Elements, as defined h
3、ere, aremajor components common to most buildings. Elements usu-ally perform a given function, regardless of the designspecification, construction method, or materials used. Theclassification serves as a consistent reference for analysis,evaluation, and monitoring during the feasibility, planning, a
4、nddesign stages of buildings. Using UNIFORMAT II ensuresconsistency in the economic evaluation of buildings projectsover time and from project to project. It also enhancesreporting at all stages in constructionfrom feasibility andplanning through the preparation of working documents,construction, ma
5、intenance, rehabilitation, and disposal.1.2 This classification applies to buildings and related sitework. It excludes specialized process equipment related to abuildings functional use but does include furnishings andequipment.1.3 The classification incorporates three hierarchical levelsdescribed a
6、s Levels 1, 2, and 3. Appendix X1 presents a moredetailed suggested Level 4 classification of sub-elements.1.4 UNIFORMAT II is an elemental format similar to theoriginal UNIFORMAT2elemental classification. UNIFOR-MAT II differs from the original UNIFORMAT, however, inthat it takes into consideration
7、 a broader range of buildingtypes and has been updated to categorize building elements asthey are in current building practice.1.5 The values stated in inch-pound units are to be regardedas standard. No other units of measurement are included in thisstandard.2. Referenced Documents2.1 ASTM Standards

See Appendix X3 fora sample preliminary project description (PPD) based onUNIFORMAT II.4.3.8 Coding and referencing standard details in computer-aided design systems. This allows an architect, for example, toreference an exterior wall assembly according to UNIFOR
13、-MAT II element designations and build up a database ofstandard details structured according to the classification.4.4 UNIFORMAT II, as described in this classification,includes sitework normally related to buildings but does notapply to major civil works. It is also unsuitable for processapplicatio
14、ns or for preparing trade estimates.5. Basis of Classification5.1 What part of the built environment is included? Theframework in Fig. 1 shows how buildings and related siteworkfit in with the rest of the built environment. This classificationdescribes exclusively the elements that make up the block
15、sshaded under the building block, that is, construction ofbuildings and related sitework. UNIFORMAT II does not treatother aspects of buildings or other features of the builtenvironment, which are indicated by the non-shaded blocks.NOTE 1The other features of the built environment in Fig. 1 are list
16、edfor illustrative purposes and are not intended to be a comprehensive list ofother features.5.2 Criteria for the ClassificationThe selectedclassification, what items to include in it, and in which parts ofthe classification to include them are based on the followingcriteria:5.2.1 The classification
17、 will be applicable to any buildingtype, while at the same time allowing for details desirable forspecialized buildings.

The classif
20、ications will be hierarchical to allowdifferent levels of aggregation and summarization. And theywill relate to other elemental classifications6such as UNIFOR-MAT and the classification of the Canadian Institute ofQuantity Surveyors.75.2.2 Items in the classification will have significant influ-ence
21、 on cost and a high frequency of occurrence. Categorieswill be defined so as to provide a framework for cost control.The decision as to where among the classification elements toinclude specific items is to rely on professional judgment as towhere building professionals in current practice normally
22、lookfor such items.5.2.3 Classification of Building ElementsFig. 2 presentsthe UNIFORMAT II classification of building elements. Itcomprises three hierarchical levels: Major Group Elements forLevel 1, Group Elements for Level 2, and Individual Elementsfor Level 3. See Section 6 for detailed lists of
23、 specific itemsthat are included and excluded under each individual elementlisted in the Level 3 category. A list of suggested level 4building sub-elements is presented in Table X1.1.5.2.4 Classification of Building-Related SiteworkFig. 3presents the UNIFORMAT II classification of building-relatedsi
24、tework. See Section 7 for detailed lists of specific items thatare included and excluded under each individual element listedin the Level 3 category. A list of suggested Level 4 building-related sitework sub-elements is presented in Table X1.1.5.2.4.1 UNIFORMAT II is not intended to classify element
25、sof major civil works. Rather, it is provided for exclusive use insupport of the construction of buildings. Buildings are usuallyconstructed with roads, utilities, parking areas, and othernon-building features. The UNIFORMAT II classification ofbuilding-related sitework provides guidance so that pla
26、nners donot have to resort to multiple elemental classifications for oneproject.6. Description of Building Elements6.1 The following lists show what items are included andexcluded in the recommended classification at Level 3. Notethat the listings of inclusions and exclusions are not intended tobe a
27、n exhaustive listing. Rather, they provide a general outlineof what to expect in that element consistent with the selectioncriteria outlined in 5.2. Exclusions are listed to help readersfind items quickly. For example, an elemental format mightshow exterior load bearing walls under Exterior Walls or
28、Superstructure. UNIFORMAT II puts them under ExteriorWalls based on technical judgment and current practice.Putting under Superstructure a cross-reference to ExteriorWalls directs the person who looks first under Superstructure tothe appropriate element. Note that the table in Fig. 2 incorpo-rates a
