Langan is providing geotechnical and environmental services related to the construction of a 10-story, 28,156-SF residential building in the Crown Heights neighborhood of Brooklyn. Langan performed a remedial investigation that identified a petroleum plume extending to the regional groundwater table, about 130 feet below grade level. Remediation included the excavation of approximately 30,500 tons of soil/fill and the removal of 23 buried tanks, as well as the design and installation of a soil vapor extraction (SVE) system incorporated into the building foundation. Langan also prepared a noise remediation plan that is being implemented to satisfy the noise “E” requirements. Langan’s geotechnical engineers completed a subsurface investigation along with a report that provided foundation design recommendations.
