Sandia National Laboratory

PB&A, Inc. designed a 30 ft. high retention wall, using cantilevered soldier beam tangent piles for this project at Sandia National Laboratory. The excavation sat immediately adjacent to a building containing highly sensitive equipment and the project required that the maximum allowable movement be limited to a ¼ of an inch. PB&A was able to use advanced computer design tools to design a system that held movement to within prescribed limits, as well as predict the deformations of the system under the building.
