159 X Nemetschek Structural User Contest 2013 - Category 2: Civil Structures Category 2: Civil Structures 2 Short description │Redesign of a Traffic Center The 3,256 sqm light-flooded roof construction is made with a vandal-proof and self-cleaning ETFE-film similar to that utilised at the “Allianz Arena” of FC Bayern Munich. ETFE-film was first deployed more than 25 years ago and it was the best alternative to expensive glass roofing. The roof structure is built at three different heights describing concentric curves with sawtooth-shaped foil panels consisting of pneumatically biased, ultra-thin membranes made of ETFE on radial steel substructures comprised of circular hollow sections with trusses in the high points and a continuous beam in the low points. Orthogonal to the radial support elements, an arrangement of crossbeams on steel columns supports the construction with foundation quivers.

It was a reward for his endeavours as an inspection engineer. Building on his experience gained from several years as a senior partner in Bremer, he and his staff planned various major engineering structures and special civil engineering structures. In 2006, Robert Thor was looking for a partnership to secure the future of his company. Eventually, in 2007, he linked up with Manfred Schipper, an engineer from Oldenburg. Schipper, also an inspection engineer, pursued his profession in Lower Saxony and Mecklenburg-Vorpommern. Robert Thor was still engaged in a search for a successor for his company in Lohne as Manfred Schipper was to stay as the office head in Oldenburg. Thor and Schipper proceeded to enter into an agreement with 48-year-old inspection engineer Tobias Schween in 2009, forming the firm ThorSchipper-Schween.
