A piece of concrete cladding has fallen off Zaha Hadid’s Library and Learning Centre in Vienna with parts of the building currently cordoned off.
The chunk of concrete, which is estimated to weigh about 80kg, had fallen from the building on Friday located at the Vienna University of Economics and Business.
No injuries were caused and the building remains open, although parts of the pedestrian street that runs through the centre of the campus have been closed as a precaution. Areas surrounding the building, as well as the space beneath the centre’s cantilevered upper levels, have been taped off.
The Austian newspaper Die Presse has reported that this is not the first time parts have fallen from the structure.
The building, which opened just over a year ago, had encountered another damage when a slab of fibre-reinforced concrete became detached last year.
The slab, measuring 1.2 by 2.5 metres, fell from the inclined façade of the centre, which leans forward at an angle of 35 degrees, featuring alternating bands of concrete and glass.
The first incident, according to Kurier, was due to an “assembly error” with the piazza in front of the building having been sealed off until the panel was replaced.
The current incident is being investigated by contractors, according to Dezeen, and are expected to reveal a report by Thursday this week.
A similar incident took place in Chicago, where the SOM-design Willis Tower’s glass viewing deck had cracked. Hadid’s Heydar Aliyev had also encountered some problems a few years ago when the roof caught fire.
