MITEK LIGHT STEEL FRAME BUILDING CATEGORY - JOINT WINNER
GLA School Hall
All trusses for the Global Leadership Academy (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 Jeffrey’s 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
96
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.
Comments from John Barnard, Director of SASFA:
“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 roof structure, 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.”
