3、elated sitework. Elements, as defined here, aremajor components 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 mon

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 prep

It excludes specialized process equipment related to abuildings functional use but does include furnishings andequipment.1.3 The Classification inco

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

It is also unsuitable for processapplications or for preparing trade estimates.5. Basis of Classification5.1 Wha

14、t 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 blocksshaded under the building block, that is, construction ofbuildings a

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 listedfor illustrative purposes and are not intended to be a comprehensiv

16、e 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 classification will be applicable to any buildingtype, while at the same time all

17、owing 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 of aggregation and summarization. And theywill relate to other elementa

18、l 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. Categorieswill be defined so as to provide a framework for cost control.The decis

19、ion 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 of the uses of UNIFORMAT II, seeBowen, Charette, and Marshall, UNIFORM

Rather, it is provided for exclus

Notethat the listings of inclusions and exclusions are not intended tobe an exhaustive listing. Rather, they provide a general out

28、lineof 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 orSuperstructure. UNIFORMAT II puts them under ExteriorWal
