Excavation Support Systems

GEI has designed excavation support systems and cofferdams for construction of numerous tunnels, buildings, and other civil works projects. Types of support systems have included but are not limited to cantilever walls, simple braced excavations, tie-back anchored excavations, open-water cofferdams, large diameter reinforced concrete shafts, braced cofferdams constructed in conjunction with existing structures, and pre-stressed bracing for structures sensitive to movements.
