ULMA Construction, the chosen partner for the tallest building in Brooklyn, 9 Dekalb.

May 18, 2020
The complexity of 9 Dekalb Avenue required ULMA to provide forming, shoring, climbing, and safety solutions to build the foundation and raise the robust and intricate structure.

The new residential tower located in Downtown Brooklyn, 9 Dekalb, will rise 1,066 feet, becoming the tallest building in the borough. The high-rise structure will join the landmarked Dime Savings Bank, a historical and monumental building founded in 1859.

The complexity of the 73-story-tower required ULMA to provide forming, shoring, climbing, and safety solutions to build the foundation and raise the robust and intricate structure. The luxurious skyscraper designed by SHoP Architects and developed by JDS Development is planned to have over 500 residential units, including commercial space.

ULMA’s lightweight handset panel MEGALITE is currently being used to erect the walls and columns of the tower. This product supports a concrete pressure of 1250 psf and allows the erection of walls higher than 8’. Right now, MEGALITE is present all over the base structure of the building while the first columns are being built. At the same time, our H20 beam slab formwork ENKOFLEX is used to form slabs with a thickness of 12 inches. The system is supported by ALUPROP posts. The aluminum shoring posts are the perfect solution to shore horizontal formwork. The props have a high load-bearing capacity, and they are easy and quick to adjust and enable ergonomic and safe working conditions for workers.

ULMA is committed to reflecting safety in the design of its systems. We promote worker safety by providing solutions such as our newly improved HWS perimeter safety screens. HWS is specially designed for high-rise buildings like 9 Dekalb. This self-climbing system protects workers from harsh weather and from them or any object to fall from the edge of the slabs.

For panel climbing and safe lifting operations, Rail Climbing Formwork RKS will be used. This system ensures safe climbing at height due to the rails attached to the walls. It is versatile and can be lifted by a hydraulic mechanism or without crane assistance.
