Designed by engineer Giacomo Mattè-Trucco, the Lingotto factory was one of the first buildings of its size to rely heavily on reinforced concrete in the construction process. The five story building featured a simple loop rooftop test track with two banked turns that consumed a 1620 foot x 280 foot portion of rooftop. The test track’s banked turns were constructed from an intricate series of concrete ribs in a construction technique that had not been used frequently before Lingotto’s construction. It is safe to say the technique had never been used for a test track 6 stories.
