Development of a Tool for Estimating Bridge Construction Contract Time

Status:  Complete
Report Date:  02/03/2020

Summary:

Investigators developed a spreadsheet tool for estimating bridge construction time that can be used when developing construction contracts. The method allows users to project time frames based on bridge design elements, work scheduling and other inputs, drawing on estimates from comparable projects stored in a 10-year database of bridge-building data. As information from new projects is added to the database, the tool will become more useful and accurate. A guidebook and training videos were also developed to support use of the estimating tool.
