Excavation in densely developed urban areas can have detrimental effects on existing structures by weakening foundations or allowing lateral movements. Careful design of the underpinning systems for adjacent buildings, as well as the staging of work, can reduce the risk of such damage. Schnabel’s experience in the design of underpinning through the incorporation of cutting edge technologies such as micropiles and jet grouting is exemplary.
For special site conditions or building requirements, Schnabel can assist you with design of specialty foundations. We are prepared to tackle design and construction issues that are not regularly handled by structural or civil engineers. In addition to our regular involvement with design of drilled shafts, auger cast piles, and testing of deep foundations, Schnabel has become the “go to” firm in the implementation of high capacity micropile systems for retrofitting existing structures or support of new facilities.
