1、Designation: E 1557 09Standard Classification forBuilding Elements and Related SiteworkUNIFORMAT II1This standard is issued under the fixed designation E 1557; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisi
2、on. 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 standard establishes a classification of buildingelements and related sitework. Elements, as defined here, aremajor componen
3、ts common to most buildings. Elements usu-ally perform a given function, regardless of the design speci-fication, construction method, or materials used. The classifi-cation serves as a consistent reference for analysis, evaluation,and monitoring during the feasibility, planning, and designstages of
4、 buildings. Using UNIFORMAT II ensures consis-tency in the economic evaluation of buildings projects overtime and from project to project. It also enhances reporting atall stages in constructionfrom feasibility and planningthrough the preparation of working documents, construction,maintenance, rehab
5、ilitation, 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 as Levels 1, 2, a
6、nd 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 a broader range
7、 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.

This allows an architect, for example, toreference an exterior wall assembly according to UNIF
13、OR-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 processapplicat
14、ions 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 blo
15、cksshaded 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 li
16、stedfor illustrative purposes and are not intended to be a comprehensive list ofother features.5.2 Criteria for the ClassificationThe selected classifica-tion, what items to include in it, and in which parts of theclassification to include them are based on the followingcriteria:5.2.1 The classifica
17、tion will be applicable to any buildingtype, while at the same time allowing for details desirable forspecialized buildings. The classification of building elementswill be separate from the classification of building-relatedsitework. The classifications will be hierarchical to allowdifferent levels
18、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 on cost and a high frequency of occurrence. Categories
19、will 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 lookfor such items.5For a more comprehensive discussion

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 cla
26、ssify elementsof 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 guidanc
27、e so that planners 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 in
28、tended tobe an 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 Exte
29、rior Walls orSuperstructure. 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.
