The university building of Saint Martin 1, designed by the architect Guy Autran, was inaugurated in 1994. The main central building is covered with a large textile and steel frame awning, hovering above the roofline with an area of 2 000m². The covering roof membrane on the surface is white PVC with the underside consisting of steel panels with perforated PVC.
Signs of water accumulation appeared early on with several pockets forming after heavy rainfall. On April 19, 1998, the portion of the awning just above the entrance had accumulated over a ton of water and the support structure collapsed, causing extensive damage.
In 2009, 3 panels on the underside of the structure began to fall and had to be taken down.
Our project consisted in identifying the design problems and proposing solutions to prevent pockets forming on the surface and reinforcing fixings for the panels on the underside whilst at the same time preserving the architectural image of the initial structure
The works included :
- replacing the metal arch profiles with the profiles increasing the slope of the membrane
- replacing the entire PVC membrane on the surface
- repairing and reinforcing supports of the underside panels with the perforated membrane
A second phase of works is programmed and will see a major refurbishment of the external facades and metal stairs.
