Bidding of Accelerated Bridge Construction Projects: Case Studies and Consensus Building

项目名称：	Bidding of Accelerated Bridge Construction Projects: Case Studies and Consensus Building
摘要：	Accelerated bridge construction (ABC) is the solution of choice to upgrade substandard bridges, while maintaining traffic flow and optimizing safety through work zones. However, the perception of higher construction costs for ABC versus conventional construction continues in spite of numerous ABC projects having lower construction costs relative to conventional construction. This inaccurate perception and the fear of cost overruns are causing some bridge owners to be hesitant about using ABC technologies, especially those technologies related to bridge system moves which can provide the greatest benefit for safety and traffic flow impacts. Whether to use ABC for a specific project needs to be decided at the project development stage. Research is needed to assist state DOTs in identifying how best to set up bid items and the bid process within their agencies to be able to effectively document ABC costs for prefabricated bridge element construction and also bridge system moves including lateral slides, longitudinal launches, and self-propelled modular transporter (SPMT) moves. This project will focus upon consensus building of bid items used for ABC projects to allow for cost-based decisions regarding ABC implementation to be made.
