SAISC Steel Awards
Southern African Institute of Steel Construction Annual Awards
“T
his year has turned out to be one of the toughest
the industry has faced. Many of the contributors
like the South African economy, policy certainty,
capacity of large state-owned enterprises to spend and
USA tariffs are out of our hands. Despite this, the industry
continues to try and influence wherever possible to get
things back on track. We should continue to persevere as
there are many stakeholders in government, our industry
and labour who are working hard to stabilise the industry.
This year SAISC had 74 entries reflecting steel as the
material of choice and a signal that we have an industry
to be proud of. Steel structures of all types are on display
due to the all-round efficiency and sustainability of the
material - it’s no wonder steel is being used more and
more. This made judging a challenging but uplifting
experience which is something we all need.
A number of projects displayed characteristics of an
exceptional industry. They showed innovation in every
process with the integration of design, detailing, fabrication
and erection using modern CNC equipment and software
which our industry has invested in so heavily.”

Time Square Sun Arena
The Sun Arena at Time Square in Menlyn Maine is the
biggest live entertainment venue in Pretoria. The purpose
of the arena is to create an events and performance space
where some of the biggest music concerts in South Africa
will be held.

The client wanted a continuous roofspan without any
columns and the arena had to be finished to international
standards. The project wasn’t envisaged in steel from the
start. The columns on which the edged gutter and roof
wedges sit were originally conceived in concrete, but due
to steel offering faster construction times, this was later
changed. The roof structure, which is a tubular truss frame
roof, plus a large gutter were done in steel. The gutter of
the roof has a steel construction tension ring and there
is a compression ring in the centre of the roof trusses.
The cladding had to be acoustically effective as well
as watertight. 86 tonnes of KlipTite cladding was used to
cover the 1,300m 2 cladding area for the project.
The roof has a 96m, column-free span, which is
unusually large. While there are many long span roofs in
warehousing projects, the unique acoustic envelope that
the team had to create makes it an exceptional project.
Detailing was done in Tekla to determine lifting sizes
and weights to ensure the steel contractor could erect
the steelwork using the most economical plant. It was
important to see the 3D model for details such as sheeting
and cladding and to model the lifting procedure and
method statement. Tekla was used to colour in the lifting
elements with element weights, which made it clear to
the engineer when approving the loads on the slabs and
determining the crane positions on the slabs.
