1、Designation: E2083 05 (Reapproved 2010)Standard Classification forBuilding Construction Field Requirements, and OfficeOverhead the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indic

2、ates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This standard covers a classification for field require-ments, office overhead, and profit for use in constructionestimating. This classification is common to all

3、 forms ofconstruction, and its components are an integral part of anyconstruction cost estimate. The classification serves as aconsistent reference for analysis, evaluation, and monitoringduring the feasibility, planning, design, and constructionphases of building. Used in conjunction with UNIFORMAT

4、 IIand other elemental classifications, including Classifica-tion E2168, it also ensures consistency in the economic evalu-ation of construction work across time and from project toproject. Through consistency in estimating and cost recordingit enhances reporting at all stages in constructionfromfea

5、sibility and planning through the preparation of workingdocuments, construction, maintenance, rehabilitation, anddisposaland is a necessary part of the reporting processdescribed in Practice E1804.1.2 This classification applies to all construction work.1.3 This classification is not based on perman

6、ent physicalelements of construction (as defined and classified in Classifi-cation E1557). Rather, the classification items are major,non-permanent, cost components common to all constructionwork. They perform the same function and provide for similarneeds regardless of the design, specification, co

9、y con-struction estimate and cost record. It classifies the non-permanent portion of construction activity that is essential toallow physical implementation of the required work to takeplace.4.2 Used in conjunction with UNIFORMAT II, this classi-fication provides for consistent and complete estimati

10、ng ofbuilding construction work, especially during the design phase.The same considerations of consistent use and commonality toall work have been applied here.4.3 This classification is sufficiently generic to allow its usein estimating all forms of construction work and through allstages of planni

Basis of Classification5.1 All parts of the built environment are included.5.2 Criteria for the ClassificationThe selected classifica-tion, the items to include within it, and with

12、in which parts ofthe classification to include them are based on the followingcriteria:5.2.1 Applies to any construction type and shall not includephysical elements of construction such as those defined inClassification E1557 and other elemental classifications.5.2.2 Includes only items of a constru
