LANSERIA INTERNATIONAL AIRPORT a steel to a concrete tower. This had obvious implications for the programme and the length of contract. Another challenge was with the roof of the control tower. “The locally-sourced lightweight composite roof structure had to be installed in panels, and along with some of the walls and the steel structure, this necessitated the use of the crane. As mentioned, cranes could be on site for only a limited amount of time, thereby effectively extending the proje ct time frame,” Von Solms points out. Interestingly, these challenges forced the team to be innovative and find solutions that would ultimately enhance the final product. “A good example of this is the fact that the cladding which was proposed for the original structural steel design, would have presented issues in terms of its fire resistance. We didn’t have this issue with concrete.” Von Solms says that it is the smaller details on the buildings that stand out for him. He cites the small recesses in the concrete and the small cladding overhangs, together with specific glass angles, as classic examples. Sustainability Not intended as a Green Building, the tower however is notable in terms of its climate controlled environment, which ensures that the critical function of the air traffic controllers is never compromised. Selecting the best possible glazing to minimise glare and using heat pumps instead of geysers have also added to the environmental stewardship of the project. In addition, the natural environment was left undisturbed to create a grassland effect that subdues the large areas of asphalt. “We are extremely pleased with the fact that we were able to problem solve on the fly, allowing us to drive the concept further. It was most enjoyable participating in the development of a landmark building and we would love to be involved in similar projects in the future,” says Von Solms.
