1、Designation: E2150 13E2150 17Standard Classification forLife-Cycle Environmental Work ElementsEnvironmentalCost Element Structure1This standard is issued under the fixed designation E2150; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revi
2、sion, the year of last revision. 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 the comprehensive hierarchical list of elements for li
3、fe-cycle environmentalwork. The classification is based on the Interagency Environmental Cost Element Structure (ECES).2 Elements, as defined here,are major components common to environmental projects.3 The elements represent the life-cycle activities for environmentalprojects regardless of the proj
4、ect design specification, construction method, technology type, or materials used. The classificationserves as a consistent reference for cost estimating, analysis, and monitoring during the various phases of the project life cycle.Using ECES ensures consistency, over time and from project to projec
5、t, in the cost management and performance measurementof environmental projects. It also enhances reporting at all phases of a project, from assessment and studies through design,construction, operations and maintenance (O communicatingproject data between installations or agencies and industry; cost

7、archical nature of the classification allows for collecting data using more detailed lower level elements or forsummarizing data at higher levels.FIG. 1 Level 1 Life-Cycle PhasesE2150 1734.7 ECES, as described in this classification, is being included in the RemedialAction Cost Estimating Requiremen
8、t (RACER)6system and the Environmental Cost Analysis System (ECAS).7 RACER is used for estimating cost and ECAS is used to collect,maintain, and analyze the cost of completed projects. Federal agencies performing environmental work intend to incorporate theECES.5. Basis of Classification5.1 In envir
9、onmental management work, the life cycle of the project is represented by six different regulatory phases. Withminor variations in the definitions, these life-cycle phases apply to most or all environmental projects including environmentalrestoration, waste management, decontamination and decommissi
10、oning, ordnance and explosive retrievals, underground storagetanks (USTs), and aboveground storage tanks (ASTs). In addition to the six regulatory life-cycle phases, a Cross Cut cost categorywas added to address costs not attributable to a particular phase or to a specific project. Fig. 1 shows the
11、life-cycle nature ofenvironmental phases.As can be seen from Fig. 1, the phases may not be linear and their sequencing may be iterative since resultsfrom one phase may require the execution of earlier phases again, to meet the regulatory requirement. Additional information oneach of the six Level 1
12、phases is provided in Fig. X1.1 of Appendix X1. The 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(Surveillance and Long-Term Monitoring). Cross Cut covers all phases of the life
13、cycle. Because the combined life-cycle phasesof environmental projects shown in Fig. 1 often span several decades, use life-cycle cost analysis (see Practice E917) for evaluatingan environmental project or project alternatives over a designated study period. Use of life-cycle cost analysis is requir
14、ed for thecomparison of alternative environmental remedies in CERCLA Remedial Investigation/Feasibility Studies which lead up toRecords of Decision.5.2 Whereas Level 1 depicts the life-cycle phases or timeframe of environmental work, Level 2 of the classification representsthe major work elements th
15、at need to be performed in an environmental project. There are thirty-four major work elementsincluded in Level 2 of the classification. In addition, there is an “Other,” element available for those unique or special tasks thatcannot be described closely by available elements. “Other” elements are d
16、esignated by .9x numbering system. For the purposesof this standard, only two levels are discussed, but more detailed levels are available. Fig. 2 illustrates a sample Level 2 for theConstruction phase. Fig. 3 represents a matrix of the Level 1 elements and how they apply to each of the Level 2 cate
17、gories.Phases 16 are listed by their phase number. The cross cut category is listed as “X.”6 RACER is a parametric cost estimating tool for environmental projects.7 ECAS was developed by U.S. Department of Energy and is being used to capture the costs of completed environmental projects.

19、life-cycle phases. The numbers inthese columns provide a general guidance on the applicability of that phase to the Level 2 major work elements that are shownin the two columns under the Major Work Elements heading. For example, the Level 2 element, Preparation of Plans, is markedwith numbers 1, 2,
20、3, 4, 5, and 6 in the left-hand columns. This means that this element can be applied or conducted duringPhases 16. If any of the numbered rows under the column entitled Cross Cut is marked with letter “X,” then that element iscross-cutting and the costs apply to more than one phase. The numbers are
21、not necessarily all inclusive or definitive. There maybe cases where an element may be applicable to a phase that is not marked or may be marked and not applicable for that specificproject. This structure is flexible, and the user can use other phases even though they are not marked in the columns.5
22、.4 Positioned between the Cross Cut column and Level 2 is the Sub-Project Identifier that uses the alphabetical designationsfrom a to z. The purpose of the Sub-Project Identifier is to allow users to differentiate between similar tasks that have the samedesignation number. For example, there may be
23、two different Disposal Facility/Process, 4.13 (Level 1Phase 4 and Level 2element .13) to be constructed. To distinguish the first facility from the second, the letters “a” and “b” (that is, “4.a .13” and“4.b .13”) could be used to designate the first and second facility respectively. The use of the
24、Sub-Project Identifier is not typicalin many environmental projects, but it is included to provide flexibility to the structure.6. Description of Environmental Cost Elements6.1 The following describes the Level 1 phases. These descriptions outline what elements are generally included and, asappropri
