Guidance for Cost Estimation and Management for Highway Projects During Planning, Programming, and Preconstruction. Final Report for NCHRP Report 574

摘要

Project cost escalation is a major problem for State Highway Agencies (SHAs). Over the time span between the initiation of a project and the completion of construction many factors influence a projects final costs. Managing large expenditure construction projects requires the coordination of a multitude of human, organizational, technical, and natural resources. Quite often, the engineering and construction complexities of such projects are overshadowed by economic, societal, and political challenges. This research developed a Guidebook on highway cost estimation practice and cost estimation management aimed at achieving greater consistency and accuracy between planning, programming and preliminary design, and final design. The Guidebook provides appropriate strategies, methods, and tools to develop, track, and document realistic cost estimates during each phase of the process.
