1、Designation: E 2150 04Standard Classification forLife-Cycle Environmental Work ElementsEnvironmentalCost Element Structure1This standard is issued under the fixed designation E 2150; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,
2、the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This standard establishes a classification of the compre-hensive hierarchical list of elements for life-c
3、ycle environmen-tal work. The classification is based on the InteragencyEnvironmental Cost Element Structure (ECES)2. Elements, asdefined here, are major components common to environmentalprojects. The elements represent the life-cycle activities forenvironmental projects regardless of the project d
4、esign speci-fication, construction method, technology type, or materialsused. The classification serves as a consistent reference for costestimating, analysis, and monitoring during the various phasesof the project life cycle. Using ECES ensures consistency, overtime and from project to project, in

It alsoenhances reporting at all phases of a project, from assessmentand studies through design, construction, operations and main-tenance (O communicatingproject data between installations or agencies and industry;cost and sc

7、l nature of the classification allows forcollecting data using more detailed lower level elements or forsummarizing data at higher levels.4.7 ECES, as described in this classification, is beingincluded in the Remedial Action Cost Estimating Requirement(RACER)5system and the Environmental Cost Analys
8、is Sys-tem (ECAS)6. RACER is used for estimating cost, and ECASis used to collect, maintain, and analyze the cost of completedprojects. Federal agencies performing environmental workintend to incorporate the ECES.5. Basis of Classification5.1 In environmental management work, the life cycle of thepr
9、oject is represented by six different regulatory phases. Withminor variations in the definitions, these life-cycle phasesapply to most or all environmental projects including environ-mental restoration, waste management, decontamination anddecommissioning, ordnance and explosive retrievals, under-gr
10、ound storage tanks (USTs), and aboveground storage tanks(ASTs). In addition to the six regulatory life-cycle phases, aCross Cut cost category was added to address costs notattributable to a particular phase or to a specific project. Figure1 shows the life-cycle nature of environmental phases. As can
11、be seen from Fig. 1 the phases may not be linear and theirsequencing may be iterative since results from one phase mayrequire the execution of earlier phases again, to meet theregulatory requirement. Additional information on each of thesix Level 1 Phases is provided in Fig. X1.1 of Appendix X1.The
12、six regulatory life-cycle phases are Phase 1 - Assessment,Phase 2 - Studies, Phase 3 - Design, Phase 4 - Construction,Phase 5 - Operations and Maintenance, and Phase 6 - Surveil-lance and Long-Term Monitoring. Cross Cut covers all phasesof the lifecycle.5.2 Whereas Level 1 depicts the life-cycle pha
13、ses or time-frame of environmental work, Level 2 of the classificationrepresents the major work elements that need to be performedin an environmental project. There are thirty-four major workelements included in Level 2 of the classification. In addition,there is an “Other,” element available for th
14、ose unique orspecial tasks that cannot be described closely by availableelements. “Other” elements are designated by .9x numberingsystem. For the purposes of this standard, only two levels arediscussed, but more detailed levels are available. Fig. 2illustrates a sample Level 2 for the Construction p
15、hase. Fig. 3represents a matrix of the Level 1 elements and how they applyto each of the Level 2 categories. Phases 1 through 6 are listedby their phase number. The cross cut category is listed as “X.”5.3 As seen from Fig. 3, the columns on the left-hand sidehave been reserved for Level 1 life-cycle
16、 phases. The numbersin these columns provide a general guidance on the applica-bility of that phase to the Level 2 major work elements that areshown in the two columns under the Major Work Elementsheading. For example, the Level 2 element, Preparation ofPlans, is marked with numbers 1, 2, 3, 4, 5, a
17、nd 6 in theleft-hand columns. This means that this element can be appliedor conducted during Phases 1 through 6. If any of thenumbered rows under the column entitled Cross Cut is markedwith letter “X,” then that element is cross-cutting and the costsapply to more than one phase. The numbers are not
18、necessarilyall inclusive or definitive. There may be cases where anelement may be applicable to a phase that is not marked or maybe marked and not applicable for that specific project. Thisstructure is flexible, and the user can use other phases eventhough they are not marked in the columns.5.4 Posi
19、tioned between the Cross Cut column and Level 2 isthe Sub-Project Identifier that uses the alphabetical designa-tions from a to z. The purpose of the Sub-Project Identifier isto allow users to differentiate between similar tasks that havethe same designation number. For example, there may be twodiff
20、erent Disposal Facility/Process, 4.13 (Level 1 - Phase 4,and Level 2-.13) to be constructed. To distinguish the firstfacility from the second, the letters “a” and “b” (that is, “4.a.13” and “4.b .13”) could be used to designate the first andsecond facility respectively. The use of the Sub-Project Id
21、en-tifier is not typical in many environmental projects, but it isincluded to provide flexibility to the structure.6.
