Architect Bruce Fairbanks is the man behind the special design of the Barcelona Air Traffic Control Tower, in which a 43 metres high self-supporting aluminium staircase is integrated. Smart design An important design requirement of the architect was that the welds would not be visible. Specifically for this project, Bayards designed and produced aluminium sections measuring up to 43 metres, that could be easily mounted on site in Barcelona, without any welding. The result is a beautiful example of how creativity in engineering and aesthetics can come together. 30
