Bank of China, Queens, New York, 2014
The ground floor and the basement of the New York offices of the Bank of China, in the Queens quarter, were recently renovated. A vault was made out of the basement, in a concrete corner isolated from the main structure.
Interbau was involved since the very beginning with a careful survey. The firm designed a spiral model 500 stairway connecting the ground floor to the vault and the basement.
The stairway was designed and produced in Interbau’s establishment of Egna, near Bolzano (Italy), and then it was assembled and installed in about ten days by our qualified engineers.
The designing was very complex: the stairway has calendered stainless steel double side boards that are parallel and very close, with just few centimeters in which glass boards are inserted as railings on both sides. The structure has to support the weight of the stairway and of people walking on it, but also the steps, made of extra clear three-layer satin glass that is 10x10x10 thick.
We take utmost care of the 3D designing as well as of carpentry models and pre-assembling structures, to ensure that each piece we produce is assembled without any problem.
The setup was particularly careful, but the structures were easily placed and assembled in three days.
