Sustainability played a major role in the choice of materials: The wood for the staircase came from sustainable forestry and the wood waste generated during the construction of the staircase was also reused. The products used were also chosen for their sustainable credentials. At the same time, they also need to withstand the high loads that are exerted on the stairs and floors by numerous visitors over long periods of time.'

Choosing the right floor coating system was an important aspect when planning the hangar. The authorities stipulated that the system used must be approved according to the German Federal Water Act. In addition, the maintenance areas in the hall needed to meet slip resistance class R11, while the planned washing area required a slip resistance rating of R11/V4. And that\'s not all: In addition to the rolling loads of the aeroplanes, the flooring – spanning a surface are of more than 10,000 m² – would also need to withstand other intensive mechanical and chemical stresses. And if that wasn\'t already challenging enough, the floor coating had to be applied within just four weeks.
