BASIS OF ESTIMATE
TCM Framework: 7.3 – Cost Estimating and Budgeting
July 28, 2010 PURPOSE AACE International’s Total Cost Management (TCM) Framework identifies a basis of estimate (BOE) document as a required component of a cost estimate. As a Recommended Practice (RP) of AACE International, the template outlined in the following sections provides guidelines for the structure and content of a cost basis of estimate. In the TCM Framework, the BOE is characterized as the one deliverable that defines the scope of the project, and ultimately becomes the basis for change management. When prepared correctly, any person with capital project experience can use the BOE to understand and assess the estimate, independent of any other supporting documentation. A well-written BOE achieves those goals by clearly and concisely stating the purpose of the estimate being prepared (i.e. cost study, project options, funding, etc.), the project scope, pricing basis, allowances, assumptions, exclusions, cost risks and opportunities, and any deviations from standard practices. In addition the BOE is a documented record of pertinent communications that have occurred and agreements that have been made between the estimator and other project stakeholders. A well prepared basis of estimate will: • • • • • • • • • Document the overall project scope. Communicate the estimator’s knowledge of the project by demonstrating an understanding of scope
