555 Greenwich

OVERVIEW
555 Greenwich is a 270,000 SF, 16-story office tower designed with sustainable, clean energy technology to minimize the environmental impact of the project while providing a healthy space for tenants. The building also utilizes its concrete superstructure and foundations for thermal energy storage. Following enrollment of the site in the New York State Department of Environmental Conservation Brownfield Cleanup Program, Langan designed the site remediation, conducted a treatability study, and addressed site soil and groundwater contamination. We also prepared boundary, topographic, and utility surveys; conducted 3D laser scans of the adjacent building fa├žade and structural components; performed construction monitoring and special inspections of the foundations; and provided subsurface investigations, a site-specific seismic evaluation, support of excavation design, and waterproofing design.
