TR-1, TR-2 &; TR-8 Special, Progress, and Energy Code Inspections. TPI provided Special Inspections and Material Testing Services throughout the conversion of the top 21 stories and other portions of this 32-story (plus 1 cellar and 4 sub-cellars), 1.2 million-square foot building from commercial offices to luxury condominiums. The building located in downtown Manhattan, across the street from 1 World Trade Center. Twin Peaks was hired by Ben Shaol’s Magnum Real Estate, who purchased parts of the building from Verizon.
This Art Deco building was built between 1923 and 1927, was designed by architect Ralph Walker, and is listed on the U.S. The National Register of Historic Places. It is widely considered to be the world’s first Art Deco skyscraper and one of the first to utilize the step back principle in response to the 1916 zoning Resolution. The special inspections were identified by the project’s Architects and Engineers of Record and designated by the NYC Department of Buildings as required items for the issuance of work permits and Temporary and Final Certificates of Occupancy.
Twin Peaks inc came onto the project early on and has assumed responsibility for and performed special and progress inspections on structural stability, steel welding, bolting, and non-destructive testing, concrete placement, masonry, chimneys, firestopping, fire resistance rated construction, sprinkler, plumbing, and mechanical systems and energy conservation items, among others. TPI also performed TR-2 concrete sampling and testing services, extracted concrete cores for testing, and ran laboratory tests on a variety of other construction materials utilized. All services, including lab tests, inspection reports and TR-2’s, were completed in-house.
