"...two of my most interesting projects,
the hangars built of pre-cast elements and the roof for the Turin
Exhibition Halls, would have been impossible without a simultaneous
invention of the structural method. They would have looked completely
different if they had been built on the same principle but in a

"The hall is rectangular and covers an
area of 240 feet x 309 feet. On one of the two shorter sides is a
semi-circular apse. Windows are arranged in the corrugation of the
prefabricated roof elements."
"A semi-circular apse 132 feet in
diameter adjoins the main hall which is 240 feet long. Its roof consists
of corrugated pre-cast units. The half-dome roof of the apse is also
constructed with prefabricated elements."
"The vaulted construction of the hall
consists of prefabricated elements which spring from in situ concrete
"The units are of "ferro-cement"
and have a length of approximately 15 feet and a width of 8 feet 3 inches.
The thickness of the curved precast parts is less than 2 inches. This
small thickness is achieved only by the increased rigidity through the
corrugation and the transverse webs at either end. The individual units
are joined by in situ concrete."
