About the research


This research seeks to leverage the work completed in National Cooperative Highway Research Program (NCHRP) 15-51: Guide for Estimating Preconstruction Services Costs by extending the parametric models developed for preliminary engineering, right of way, etc. to the estimating of construction project cost at the earliest stages of project planning and development. It will deliver a top-down cost estimating model that uses "stock" spreadsheet and database software without the need to purchase special software or hardware (i.e., Microsoft Office products only).
