Development of a Tool for Estimating Bridge Construction Contract TimeStatus: CompleteReport Date: 02/05/2020 Summary: The purpose of this project was to develop a tool, available at mndot.gov/research/reports/2020/20201S.xlsm, that estimates bridge construction contract time based on various controlling activities of bridge construction. As part of this project, various transportation departments throughout the United States were interviewed on how contract time is established in their states. Many states had some sort of estimating tool that aided in establishing contract time, while others followed the process and protocols established by the Federal Highway Administration (FHWA). Chapter 5 of this report contains a user manual for the spreadsheet. The MnDOT Bridge Office also developed four instructional videos.
