Description
One Bryant Park is 985 feet high and has a total of 2.15 million square feet of space. This glass tower is the headquarters of The Bank of America. The building displays defined vertical lines, that with the movement of the sun and the moon, modify the perception of the building.
Its shape is made in such a way that it provides a view facing south, in this way highlighting its relation with Bryant Park and offering views within and beyond the structure.
With its 55 floors, this office skyscraper is considered to be one of the most respectful buildings towards the environment, since it was built mostly of recycled and recyclable materials. Innovative technologies were applied that required less energy, systems to reuse residual water, a heat storage system, translucent insulating glass to potentiate natural light, a ventilation system that supplies fresh air at floor level.
ULMA Solution
In this construction project, the ATR Self-climbing System was used all the way from the structure's underground levels to the last floor. The ATR self-climbing system lifts itself without the need of a crane, thanks to the incorporated hydraulic system.
In a building with these characteristics and with a multitude of materials used, the tasks of the various workers needed to overlap. The use of the ATR system increased productivity, reducing work times since it made it possible to complete different tasks simultaneously. Unlike conventional systems, the ATR greatly reduces crane time, as well as providing simple and fast methods for climbing.
Additionally, this system permits the assembly and preparation of the lifting mechanisms and platforms before the formwork set up. It operates as a lifting tower, anchoring into the walls that have already been built.
This self-climbing technique is based on a hydraulic system that enables the gang to be automatically lifted through the successive movements of the formwork and the masts. With this system, along with the MEGAFORM Modular Formwork, the process of the forming of the walls of this building was completed efficiently.
