Excavation Support Systems
GEI combines empirical experience with sophisticated computer modeling to evaluate the impacts of excavations and various support of excavation (SOE) systems on existing adjacent buildings and facilities. Using geotechnical instrumentation during construction allows our experts to evaluate actual vs. predicted performance of a system and make the necessary adjustments.
During construction of new structures where open cuts are not feasible, SOE’s support the ground outside excavations to control deformation of adjacent structures, utilities and soil. SOE’s range from simple piles and lagging or sheeting, to complex slurry wall projects protecting sensitive and historic structures. Types of support systems have included but are not limited to cantilever walls, simple braced excavations, tie-back anchored excavations, open-water cofferdams, braced cofferdams constructed in conjunction with existing structures and pre-stressed bracing for structures sensitive to movements.
