Update Bridge Construction Requirements

In 2020, the American Association of State Highway and Transportation Officials (AASHTO) Committee on Bridges and Structures (COBS) completed a project to investigate the use and effectiveness of the current AASHTO LRFD Bridge Construction Specifications (BCS). The project included a questionnaire to each state to determine the use of the document, a review of the document contents, the development of a prioritized approach for reorganizing and maintaining the document, and the development of prioritized recommendations for updating the document. The study concluded that the AASHTO LRFD BCS is being used by many state transportation agencies (STAs) on a regular basis, justifying future updates and maintenance. The study recommended (1) converting the document to a guide specification, (2) adding commentary similar to the AASHTO LRFD Bridge Design Specifications, and (3) updating existing content and adding new content as needed to be consistent with current industry standards and STA specifications. The study provided options for reorganizing the AASHTO LRFD BCS. Research is needed to develop recommendations for updating the bridge construction requirements to be considered by the AASHTO COBS in its next update to the AASHTO LRFD BCS. The objective of this research is to develop recommendations for effective bridge construction requirements that align with current bridge design and construction methods to provide clear expectations and minimize ambiguity.
