T/E/S/S comprises some 50 engineers and architects, headed by Tom GRAY, Matt KING and Bernard VAUDEVILLE. As engineering consultants, T/E/S/S works on the design and production of structure, facades and building envelope. This work applies to edifices of all kinds, including civil engineering and more unusual projects such as art installations or experimental structures. Our work is founded on a solid experience of structural calculations, on an in-depth knowledge of materials – steel, aluminium, timber, glass, concretes, textiles and composites – and on an expert understanding of complex geometry. T/E/S/S was awarded the 2012 Grand Prix National de l’Ingénierie for the Fondation Louis Vuitton project.
