“What struck me about this project was how closely the final structure resembles a sketch drawing used originally to promote the solution! This is not the lowest mass per area roofstructure, but some clever design using MiTek’s Ultraspan, captured benefits made possible by high strength low mass steel trusses, and realised the arcitect’s design. From natural ventilation to optimisation
of natural light, photo voltaic cells and rainwater harvesting, to the recyclability of materials used – LSF made this green structure possible! Hence it was selected to be a joint winner
in the LSF Category of Steel Awards 2017!” – John Barnard, Director Southern African Light Steel Frame Association.
All trusses for the GLA school hall roof were spanned parallel to the traditional supports, essentially producing enlarged rafter/purlin type trusses. Ultra-Span girders were created at the ends to support short span trusses to comply with the required minimum ceiling height. This idea was also adopted in the middle section of the roof to act as stability braces for the window panels. Window panels were made with MiTek’s wall framing product to allow for very specific window sizes, and to provide flat surfaces for fixing of such windows. These window panels are manufactured in several parts to ease installation.
In typical large span Ultra-Span style, the 19m trusses were preassembled in braced pairs and then lifted into their final position on the roof, to ensure fast erection of the roof structure skeleton and enabling other installation works to continue on a stable platform. Satisfied customer, Stefan Kleyn from the Global Leadership Academy, says, “With the design and construction of the new school buildings for Global Leadership Academy in Jeffreys Bay, we were confronted with the challenge of establishing a world-class education facility on a shoe-string budget. This required our architect, Jacobus Scott, to come up with innovative solutions. One of these problems was that we wanted a multi-use gathering area, which required an ultra-long span roof design. There was just no other cost-effective option but to make use of the MiTek Ultra-Span system. Brian and the rest of the MiTek team designed and installed a cost-effective solution that not only looks impressive but also effectively solved many design and engineering problems that we just couldn’t have overcome with a traditional roofing system. We applaud the complete MiTek team and especially Brian for guiding us through this process.
