During the construction of the Stade de la Tuilière, opened in November 2020, Ingphi took part in construction controls.

The structural concept of this 12,000-seater stadium is a pre-stressed traction ring which stabilizes the four corners like a girdle. The raised corners give the stadium its distinctive geometry.

Espazium recently released a publication on this structure, a special supplement to the January 2021 edition of the journal Tracés.
