Renovation work on the Polygone centre chiefly involoves demolishing the existing roof and building a 3,300 m² canopy composed of ETFE cushions. This canopy will rest on a steel framework of crossed arches, and the whole structure will constitute Eiffage Métal's Lot 2A «Framework, Roofing». We are also to build the 1,100 m² of façade surrounding the new canopy.
Installation work is scheduled to begin in Spring 2019, with completion and delivery in December 2019.
*ETFE : Ethylene tetrafluoroethylene.
