Abstract:Repairs to underwater bridge elements have been successfully completed for many years. However, the increased age of the nation’s bridges and related structures, as well as the increased emphasis in regular underwater inspection since the revisions to the National Bridge Inspection Standards in 1988 indicates an increased need to perform repairs to elements located below or in water. This manual is intended to serve as a reference for design engineers, construction inspectors, resident engineers, inspection divers and other administrative and technical staff whose work tasks include the repair or rehabilitation of elements of bridges or similar structures located below water. The manual addresses a variety of design and construction issues that must be considered in determining the feasibility of, and selecting the repair or rehabilitation methodology, for underwater projects. This information can aid in developing cost effective and durable repair and rehabilitation designs.
