摘要

Typically, Project Management (PM) and engineering costs areestimated as a percentage of the overall direct field constructioncosts and are developed using a simple set of known estimatingmetrics and fragnets for engineering phases of work. This limitedapproach lacks an interrogative basis and results in cost estimatesfor PM and engineering functions which are very limited. Thismakes it difficult for an owner to validate baseline budgets andschedules. The author recently developed a new estimating tooland approach to developing these functional costs. The new toolbases development of these costs on the activity, tasks, deliverablesand resources defined by the client organization’s governance.This achieves a bottom’s up, granular estimate which quicklyapproaches an AACE Class III level estimate. This level estimate hasa high level of confidence very early on in the project life cycle.Articulation of the process, when applied fully, will build confidencein the AACE class estimate and provide assurances to PM of theaccuracy of the engineering costs, as early as the investmentappraisal and conceptual engineering phases. Since the authorwas able to develop these costs on a resource-deliverable basis,the data coming from the tool has the potential to improve a varietyof organizational planning and reporting activities. Improvementmay be seen in the owner’s organizational resource validation,confirmation of headcount requirements over project life cyclephases, and validation of lace ups between interfacing governanceprocedures. The process provides the planner with tools foralignment to a work breakdown structure. It is aligned to any stagegate syndrome and through its resource identification it providesearly insight of potential performance management issues.
