The new Stadium for the Polish First League soccer club Legia Warsaw is the first example of a series of new Polish stadium projects. It implements the new safety regulations for modern stadia as well as state-of-the-art comfort features. The new stadia will showcase new structural solutions as well as new materials, mainly for the roof systems. The roof structure for the Legia stadium show most elegant the forming of the three-chord truss girder, based on the structural requirements. The cladding is a combined solution of a translucent Teflon coated glass fiber membrane on the majority of the roof surface and a transparent polycarbonate sheeting area at the inner roof edge. The design team and the group of contractors delivered a truly modern and already highly appreciated stadium.
