Identification, analysis, and management of the risk of project-cost escalation are fundamental challenges facing the transportation industry. Recently completed NCHRP Project 8-49, "Procedures for Cost Estimation and Management for Highway Projects During Planning, Programming, and Preconstruction," focused on the issue of cost escalation and developed a guidebook on highway cost-estimation management and tools aimed at achieving greater consistency and accuracy in long-range transportation planning, priority programming, and preconstruction estimates. The scope of NCHRP Project 8-49 called for development of multiple strategies for controlling cost escalation, but did not allow for in-depth treatment of methods and tools necessary to implement a specific strategy for risk management. NCHRP Project 8-49 identified risk analysis and management as primary strategies to help control cost escalation (see Special Note F). The objective of this research is to develop a comprehensive guidebook on risk-related analysis tools and management practices for estimating and controlling transportation project costs. The guidebook must include a plain language toolbox for transportation agencies to use in selecting appropriate strategies, methods, and tools to apply in meeting their cost-estimation and control goals and objectives. This guidebook will be especially applicable to planning, priority programming, and preconstruction phases. |
