EngineeringCost:AReviewofRelevantLiterature

Introduction

Engineeringcostreferstothefinancialaspectofplanning,designing,andconstructingengineeringprojects.Itinvolvesestimatingandallocatingresourcestoachieveprojectobjectiveswithinaspecifiedbudget.Thispaperreviewsrelevantliteratureonengineeringcosttounderstandthefactorsinfluencingcost,costestimationmethods,andtechniquestocontrolcost.

FactorsInfluencingEngineeringCost

Severalfactorsinfluencethecostofengineeringprojects.Ribeiroetal.(2019)highlighttheimpactofprojectsize,complexity,siteconditions,andprojectdeliverymethodoncost.Large-scaleprojectstendtohavehighercostsduetotheincreasedscopeandduration.Increasedcomplexity,suchastheintegrationofadvancedtechnologies,alsoimpactscost.Siteconditions,includingsoilcompositionandtopography,affectthecostoffoundationandexcavationworks.Additionally,theprojectdeliverymethod,suchasdesign-bid-buildordesign-build,caninfluencecostduetodifferencesinriskallocation,qualitycontrol,andcollaboration.

CostEstimationMethods

Accuratecostestimationiscrucialforprojectsuccess.Severalcostestimationmethodsareemployedinengineeringprojects.TechnologiessuchasBuildingInformationModeling(BIM)andcomputer-aideddesign(CAD)softwarearecommonlyusedforquantitytakeoffsandcostestimation(Maoetal.,2020).Thesetoolsenableengineerstogeneratedetailed3Dmodelsandextractquantitiesautomatically.Parametricestimating,anotherwidelyadoptedmethod,utilizeshistoricaldataandmathematicalmodelstoestimatecostsbasedonprojectcharacteristics(Vahdatalabetal.,2019).Furthermore,expertjudgmentandanalogestimatingaremethodsoftenemployedwhendataislimitedorunavailable.
