Synthesis of Available Contracting Methods

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. While the traditional contracting method for state DOTs is primarily unit price contracting, there are alternatives, including cost plus, lump sum, lump sum with guaranteed maximum price, and progressive lump sum with a guaranteed maximum price. To date there has been little investigation into the use of these alternatives on ABC projects, this project will explore the use of these options to understand the state of practice and provide insights and lessons learned for DOTs.
