Designation:F167513Standard Practice forLife-Cycle Cost Analysis of Plastic Pipe Used for Culverts,Storm Sewers,and Other Buried Conduits1This standard is issued under the fixed designation F1675;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 last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This practice establishes a procedure for using life cyclecost(LCC)analysis techniques to evaluate alternative drainagesystem designs,using plastic pipe that satisfy the samefunctional requirements.1.2 The LCC technique measures the present value of allrelevant costs to install,operate,and maintain alternativedrainagesystemssuchasengineering,construction,maintenance,rehabilitation,or replacement over a specifiedperiod of time.The practice also accommodates any remainingresidual or salvage value.1.3 The decision maker,using the results of the LCCanalysis,can then identify the alternative(s)with the lowestestimated total cost based on the present value of all costs.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 Other Standards:TM-5-802-1 Economic Studies for Military ConstructionDesign Applications(12/86)2Federal Office of Management and Budget Guidelines andDiscount Rates for Benefit-Cost Analysis of FederalPrograms and state documents for guidelines or require-ments32.2 ASTM Adjuncts:Discount Factor Tables43.Terminology3.1 Definitions:3.1.1 common costs,ncosts that are common to all alter-natives in nature and amount,such as initial planning fees orfuture annual inspection costs.3.1.2 discount rate,nthe investors time value of money,expressed as a percent,used to convert costs occurring atdifferent times,to equivalent costs at a common point in time.3.1.3 drainage project,na project having a definable,functional drainage requirement that can be satisfied by two ormore design or construction alternatives,or both.3.1.4future costs,ncosts required to keep the systemoperating that are incurred after the project is placed in service,such as operation,maintenance,rehabilitation,or replacementcosts.3.1.5 inflation,nthe general trend or rising prices that,over time,result in the reduction of the purchasing power ofthe dollar from year to year.3.1.6 initial cost,nthe total of all costs;such as designcosts,material purchase costs,and construction/installationcosts,that are specific to each alternative and are incurred tobring each alternative to a point of functional readiness.3.1.7 maintenance cost,nthe annual or periodic costs,such as inspection and cleaning to keep a drainage structurefunctioning for the project design life,but do not extend thematerial service life.3.1.8material service life,nthe number of years ofservice a particular material,system,or structure will providebefore rehabilitation or replacement is necessary.3.1.9 project design life,nthe planning horizon for theproject,expressed as the number of years of useful life requiredof the drainage structure.3.1.10 rehabilitation cost,nthe total of all costs incurredto extend the material service life of a specific alternative.3.1.11 replacement cost,nthe total of all costs incurred toreplace a material before the end of the project design life.3.1.12 terminal value,nthe remaining value of the drain-age structure in place at the end of the project design life.4.Summary of Practice4.1 This practice outlines a procedure for conducting anLCC analysis of two or more drainage pipe alternatives using1This practice is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.62 on Sewer.Current edition approved Aug.1,2013.Published August 2013.Originallyapproved in 1996.Last previous edition approved in 2009 as F167509.DOI:10.1520/F1675-13.2Available from Headquarters,Department of the Army,Washington,DC.3Available from Office of Management and Budget,Washington,DC.4Available from ASTM International Headquarters.Order Adjunct No.ADJE091703.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 plastic pipe over a specified project design life.This practiceidentifies the project data and general assumptions needed forthe analysis and the method of computation.5.Significance and Use5.1 LCC analysis is an economic method to evaluate alter-natives that are characterized by differing cash flows over thedesignated project design life.The method entails calculatingthe LCC of each alternative capable of satisfying the functionalrequirements
