Improving Cost Estimates for Preconstruction Services

The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores NCHRP Report 826: Estimating Highway Preconstruction Services Costs, which explores ways to implement a framework for data-driven cost-estimating models for transportation projects. This framework helps agencies to estimate how much it will cost to plan, program, permit, and design a project during the early phases of project development.
