New Jersey State House

The New Jersey State House is undergoing a comprehensive renovation to preserve and restore the building’s historic interiors and façade, overhaul and modernize the HVAC systems, address water infiltration, and replace the building’s roofs. Site updates include renovation of the northern entry plaza, addition of an executive parking lot with accompanying security upgrades, reconstruction of perimeter areaways, ADA improvements, drainage and utility upgrades, and landscape and lighting improvements. Langan provided survey and 3D laser-scanning services and is now providing site/civil engineering and landscape architecture related to the site improvements; geotechnical engineering to support the new mechanical, electrical, and plumbing systems, including extensive underpinning and support-of-excavation design; and hazmat investigation, design, and oversight during the remediation of asbestos-containing materials and lead-based paint.
