A specialty contractor must consider many issues prior to deciding to participate in a plate bonding project. The most significant of these issues are feasibility, practicality, and the potential for teamwork between the owner designer, and specialty contractor. Assuming that plate bonding is technically feasible for a specific application, there are still many aspects to consider to insure a seccessful project. Acceptance is an expeditious manner by all parties, coupled with a good understanding of the existing and expected conditions, are critical to the decision. Plate bonding offers many unique advantages that are often realized when repair options are being reviewed. Typically, when this method has been used, it was done so because it was cost effective, minimized down time, did not increase deadload, and had little visual impact on the structure. A series of case histories, including bridges, post-tensioned slabs, and load-bearing walls, highlight the advantages and challenges a contractor may encounter when using this technology. When plate bonding as a repair option is selected early in the design process by all parties involved, then the benefits of a rapid, cost effective, and simple repair process can most readily be realized.
