John P. Stopen Engineering (JPS, LLP) provided Geotechnical engineering services for the design of approximately 500 lineal feet of support of excavation, dewatering and geotechnical instrumentation, and directed construction inspections for Earthwork Contractor for excavation up to 28 ft. deep next to a 9-story building.
Performed detailed, finite-element analyses for evaluating potential settlement of adjacent 9-story patient tower to design: secant wall, soldier piles and lagging, steel sheet piling, drilled-in, tie-back ground anchors, underpinning, dewatering, piezometers, and inclinometers. Used computer graphic modeling to avoid drilling into buried utilities.
