PREFABRICATED STEEL BRIDGE SYSTEMS FHWA SOLICITATION NO. DTFH61-03-R-00113 - Final Report - September 2005

Oct 23, 2026

Final report prepared for the Federal Highway Administration office of acquisition management in September 2005, focused on prefabricated steel bridge systems. It reviews the problem background, study objectives, and report structure, then surveys historical steel bridge developments, including temporary/emergency and permanent superstructures and prefabricated steel piers. The document outlines accelerated construction minimum system requirements, presents new concepts and system evaluations, and develops optimization formulations and methods, including genetic algorithms and surrogate-based optimization, followed by results and recommendations.
