DOE G 413.3-21, COST ESTIMATING GUIDE (05-SEP-2011)
DOE G 413.3-21, COST ESTIMATING GUIDE (05-SEP-2011), The purpose of the DOE Cost Estimating Guide is to provide uniform guidance and best
practices that describe the methods and procedures recommended for use at DOE in preparing
cost estimates that is specific to all work including but not limited to construction projects and/or
programs. This guidance is applicable to all phases of the Department’s acquisition of capital
asset management activities. Practices relative to estimating life-cycle cost (LCC) are described.
LCCs include all the anticipated costs associated with a project or program alternative
throughout its life; i.e., from authorization through operations to the end of the facility/system
life cycle (see Figure 3-3 in Section 3.2).
This Guide does not impose new requirements or constitute DOE policy, nor is this Guide
intended to instruct Federal employees in how to prepare cost estimates (see Appendix C,
Summary of Federal Requirements, and Appendix D, Summary of DOE Requirements). Rather,
it may be used to provide information based on accepted standard industry estimating best
practices and processes—including practices promulgated by the GAO Cost Estimating and
Assessment Guide (GAO-09-3SP)—to meet Federal and DOE requirements and facilitate the
development of local or site-specific cost estimating requirements. The GAO has specifically
recommended that DOE cost estimating guidance be provided following the GAO Twelve Steps
of a High-Quality Cost Estimating Process to improve the quality of its cost estimates (see GAO-
10-199, Table 1, page 10).
