75 Rockefeller Plaza (New York) is a comprehensive renovation and repositioning of the Landmark 33-storey original headquarters for Rockefeller’s Standard Oil Company completed in 1947. This Landmarked building will be rebuilt to a nearly new condition and a major concourse will be introduced to connect 51st and 52nd Street.
This concourse will become the largest public concourse space in the Center and will be adorned with art in keeping with Rockefeller’s original vision. The building is targeting LEED Gold certification and as the new benchmark for high end office space in the center.
On 51st Street facing the famous Rockefeller Plaza, the massive but damaged bronze plaque will be replaced with a fortified new bronze plaque and the flanking storefronts will be refurbished with a new energy efficient glazing using parts from the original building to keep the building authentic. The architectural bronze recovered from the renovation will be collected and reused where possible.
The office levels will be refurbished for class A tenants including re-construction of the cores, new stairs, elevator shafts/system and cabs, restrooms, mechanical rooms and energy efficient mechanical systems, current fire alarm and extinguishing systems, and electrical rooms.
The roofing systems will be replaced with a new system and green roofing system at the main roof and terraces. The existing windows will be replaced with thermally improved aluminium windows with LowE high performance insulating glazing. Additional insulation will be added behind the existing limestone walls and the limestone will be cleaned and the joints repointed.
