Empire State Building Antenna Mast
New York, NY
Project Square Footage
207 ft. tall
The construction of the Empire State Building lasted from March 1930 to May 1931. The 102-story building is 1,250 feet tall; 1,457 feet including its antenna mast.
Architectural Resource Consultants (ARC) provided HDS 3D Laser Scanning, photo imagery, and modeling services to document the antenna mast atop the Empire State Building.
This was an extremely dangerous and challenging project involving climbing a 200-foot antenna mast at the top of one of the tallest buildings in the world in order to document the antenna mast structure and infrastructure. 3D laser scanning and advanced 360 HDR (High Dynamic Range) photo imagery were utilized.
ARC custom fabricated scanner rigs designed specifically to meet the unique conditions of this project. The resulting documentation led to the development of a 3D BIM.
This project demonstrates ARC’s ability to perform as-built surveys in extremely challenging environments and meet expedited schedule constraints.
