To achieve the completion date
of 2007, Ban designed a temporary structure (built in a student
workshop in summer 2004) that will house architects from his
office and the local architect Jean De Gastines. Located on
the roof of the Pompidou in Paris, the lightweight structure
is "a tubular space of
34.5m in length and 4.4m in width. The circular vault space
is entirely covered in its length by a waterproof membrane
and panel system that is supported on a system of cylindrical
ribs. These are made of 29 semi-circular arches, equal in
length, and a network of transversal wind-bracing elements.
The arches are at 1.2m intervals. The ribs are made of paper
tubes, inside 120mm diameter, 760mm external diameter." |
