Rapid Bridge Construction Methods Applied to Piers and Wharves

The United States Coast Guard (USCG) is challenged by aging infrastructure that has reached a point where many of the existing structures need to be replaced or repaired within constrained timelines or even while still operational. In recent years, a tremendous amount of work has gone into the development of Rapid Bridge Construction (RBC) methods. Rapid Pier Construction (RPC) is analogous to RBC in many ways, as bridges share similar structural elements and operational considerations as marine structures. In 2009, the USCG commissioned a study of RPC focusing on streamlining the construction process by accelerating the critical path steps and minimizing interruptions to operations. RPC has many potential benefits over typical pier and wharf construction, including potential overall cost savings, increased lifespan, higher durability, and reduced maintenance. RPC has a focus on the use of large precast components in modular construction, saving time on formwork and concrete curing. This paper addresses the applicability of RBC methods to the development of waterside infrastructure, piers and wharves. It also includes a review of literature related to RBC methods and materials, the development of an RPC concept, and recommendations for future applicability of RPC to construction in the marine environment.
