Effective Timelines and Contractual Strategies for Accelerated Bridge Construction Projects

State departments of transportation (DOTs) strive to minimize the impact of construction activities on the traveling public and commerce. Contractual provisions and methods such as incentives/disincentives (I/D), payment for acceleration, bonuses, liquidated damages (LD), and cost-plus time (A+B) procurement have been used for conventional construction projects to promote meeting project schedule targets. In addition, accelerated bridge construction (ABC) methods can greatly compress the closure time required during bridge construction. Generally, ABC minimizes the overall construction window or minimizes the out-of-service time of the facility. Shorter onsite construction schedules reduce mobility impacts and improve safety; however, there is potential for risks related to accelerated schedule. Generally, ABC techniques alleviate significant user costs; however, these technologies may have significant project costs that are difficult to accommodate within limited owner construction budgets. For example, the use of self-propelled modular transports (SPMT) could significantly increase the construction cost of a project. Research is needed to help DOTs identify practical goals for project schedules, effectively use contractual strategies, and better understand schedule risks associated with ABC projects. The objective of this project is to provide contractual guidance for ABC project development considering the design-bid-build project delivery method. At a minimum, the research shall identify: (1) Types of construction contractual provisions such as I/D, bonuses, LD, A+B, etc.; (2) Appropriate values for the identified contractual provisions such as the amount of money assigned for each day/hour saved or added; (3) Associated closure timeframes (partial or full; continuous or intermittent); and (4) The risks of accelerated timelines, and how those risks are addressed.
