Adapting Underpinning and Excavation Support in 200-Year-Old NYC Buildings

With the rise in property values and market push of luxury construction in NYC we have seen the requirement for adapting classic underpinning design with modern construction techniques. This project, located within the trendy SoHo/NoLita district is where several existing 150 to 200-year old historic landmark structures are to be converted from institutional use to luxury residential townhouses and condominiums. In order to provide the required below-grade space necessary for the proposed construction, the existing foundations on these historic landmark buildings would need to be extended up to 20 feet deeper than their original construction.
