In 1991 the Federal Highway Administration (FHWA) required all states to provide Plans of Action (POA) for scour critical bridges. A nationwide mandated requirement by the FHWA, tasked the Colorado Department of Transportation (CDOT) to re-evaluate and develop POA reports for each of the 243 bridges identified as scour critical or structures with unknown foundations. cdot created a program to address the scour critical bridges and create a multi-disciplinary POA team. As a part of this effort, Hydrau-Tech, Inc. was in charge of conducting 135 POA studies and developed individualized reports for each structure over a period of three years. As of September 2013, Hydrau-Tech, Inc. has completed 113 POA reports for CDOT, along with an additonal 19 reports for structures with unknown foundations.
