TWEED COURTHOUSE
Extensive site improvements were proposed as part of the restoration program for Tweed Courthouse within the northern edge of City Hall Park in Manhattan. Langan provided full design drawings for these improvements, which included bluestone paver, granite paver and cobblestone walks, custom-made ornamental picket fences and gates, bollard-and-chain railings, historic-style lighting, and perimeter landscaped spaces. Langan also prepared and supported Builder’s Pavement Plans which allowed for the extension of the building into the Chambers Street right-of-way and the re-routing of the public sidewalk into the former paved carriageway. Other design services provided by Langan included structural design of building exterior area-way elements, handicapped access ramps, related retaining walls, underground vault roof slabs, and other building peripheral elements. Langan worked in close coordination with the project architect and archeologist to move the project along rapidly while ensuring dimensional control and making necessary grading revisions due to the presence of archeological remnants. Langan also provided inspection and consulting services to ensure that the highest standards were met for the surface finishes and site furnishings.
