TBM Cost Estimate Cost Estimate Schedule ApproachTom MannOctober 27, 2005
Cost Estimate Approach • Identify Scope • Develop Work Breakdown Structure and WBS Dictionary • Develop cost estimate • Establish cost contingency needs based on risks • Establish a cost range • Develop resource-loaded schedule Identify Scope
Cost Estimate Approach Cost Estimate Guidelines base on ITER • Guidelines for Assembling the Cost Estimate, Schedule and Risks for Submittal of CD-1 for SNS Power Upgrade Project • Objective: In support of the CD-1 decision planned for Fall 2005, it is necessary to develop and assemble a sustainable, reviewable cost estimate, schedule, and risk analysis for the SNS Power Upgrade Project (PUP). Your input to support this objective is needed no later than June 30. • Background: On November 23, 2004, the Statement of Mission Need for Spallation Neutron Source Proton Beam Power Upgrade Non-Major Systems Acquisition was approved and stated: “The TPC (Total Project Cost) for an SNS power upgrade project has been roughly estimated to be in the $120 – 160 million range.” The document further states that there is “reasonable confidence in this range.” While the requirement for CD-1 is still for an estimate range, the level of detail to support the range must be greater than what currently exists. • In general, your estimate must be defendable at an External Independent Review. The estimate should be realistic with a 50% confidence level, that is, there is a 50% chance that the actual costs will be either higher or lower than the cost estimate. In other words, provide your currently best available cost estimate without contingency. Contingency will be added separately based on your input. The cost estimate developed for CD-1 will be maintained under configuration control and serve as the basis for future updates and revisions. Our estimating approach must include backup details adequate to support the WBS level presented in the External Independent Review. Detailed cost estimate sheets (attachment 3) are provided to capture this backup detail information.
