Description
Designed to be the highest residential tower in Brooklyn, Brooklyn Point is over 720 feet tall with 68 stories and will include the highest infinity pool in the western hemisphere. Along with 458 luxury residences the building sports 40,000 square feet of indoor and outdoor amenities. Brooklyn Point will be the first for sale residential property in Citi Point Brooklyn and be the largest destination in Brooklyn for shopping, food, and entertainment.
ULMA’s dependable service, efficient and steady products, and continued support of the project with engineers on site is the reason ULMA can take part in creating this beautiful building in Brooklyn New York.
ULMA solution
ULMA worked directly with the customer to provide comprehensive support for this project, including engineering solutions using ULMA’s forming, shoring, and safety windscreen systems. All products had continued project support with engineers on site from beginning to end.
The beginning of the project consisted of forming tall monolithic columns and walls that were more than 20’ high. Utilizing ULMA’s 8’x24” MEGALITE forming panels a total of 16,000 SQF of formwork was used to form and build both the inside and outside columns/walls of the building.
To support the typical slabs and any other irregular slab geometries ULMA’s adaptable Timber Beam shoring system ENKOFLEX was used. The total shoring used for the 68 story building was an average of 11,000 SQF with typical floor heights of 9’-11” to 10’-11”. The quick erection of ENKOFLEX allowed the customer to keep their desired concrete cycle of 3 days.
A critical part of the building’s design was a transfer level that was 26’ tall. To support this floor ULMA’s engineers had to design shoring spans between 13 and 17 feet long. To solve that particular problem ULMA used combinations of MK Walers (heavy duty steel channels) and ALUPROP towers to support the shoring spans for the 9 inch thick concrete slab with a shoring height up to 26 feet high.
The columns and walls in the transfer floor were built with MEGALITE gangs and added C6 channels to make increase the gang’s rigidity. In order for the customer to stay on schedule some of the gangs were pre-assembled in ULMA’s yard, delivered to the site, and lifted into place on the same day.
The HWS safety perimeter windscreen was selected by the customer to protect their workers while performing work around the construction jobsite. 36 HWS units where designed to surround the building and cover 4 and a ½ building floors. Each HWS unit included walkways for access from the HWS structure to the building itself. To accommodate any construction hoists and crane supports the windscreens where build with a flat design so that the HWS screens could fit between the building edge and crane and hoist.
The client chose to use the HWS windscreen, a perimeter cocoon that focuses on perimeter safety for workers in high rise buildings; MEGALITE, a handset panel for wall and column formwork, and ENKOFLEX a wood beam shoring system to support the shoring heights of 10 to 12 feet high.
The conditions of this project required the client to be on a “three day” concrete pouring and stripping cycle. Using MEGALITE and ENKOFLEX the formwork and shoring could be erected and stripped within the three days, and the entire HWS windscreen could be moved in one day using ULMA’s hydraulic units and two workers.
