During the repair methods and shotcrete materials were design phase, Epoxy Design Systems, Inc. (EDS) incorporated to meet design criteria, including worked closely with Stanley, Spurling & Hamilton technical test data for material choice, constructibility Engineering to provide conceptual ideas for materials, for different repair types and conditions, and coordi- as well as restoration means and methods to incorpo- nation of materials with Quikrete. Specifications were rate into the overall project. EDS provided expertise developed for specific pier areas requiring different based on 35 years of structural concrete restoration repair solutions (refer to Fig. 2 and 3).
