1、Designation: E 2083 05Standard 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 indicates the year of

2、last reapproval. Asuperscript epsilon (e) 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 forms ofconstru

3、ction, 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 IIand other ele

4、mental classifications, including ClassificationE 2168, it also ensures consistency in the economic evaluationof construction work across time and from project to project.Through consistency in estimating and cost recording it en-hances reporting at all stages in constructionfrom feasibilityand plan

6、ents of construction (as defined and classified in Classifi-cation E 1557). 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, constructionmetho

9、on-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 estimating

10、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 planning,

11、 design, use, and disposal. Additionally, it isappropriate for use in both elemental estimates and tradeestimates.5. 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 within

12、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 E 1557 and other elemental classifications.5.2.2 Includes only items of a construct
