skraal, 30km north of Pretoria and is
a state of the art mall, which covers
52 000 m² and accommodates over
100 retail and speciality stores.
Giant Engineering specified
MiTek’s Ultra-Span roofing system.
The project required 350 trusses
and 4 600 m² of the MiTek Ultra Span
system. The initial plan was to erect
the roofing system in four weeks but
Giant Engineering completed the
project in just 14 days, which enabled
the company to save almost 50% on
labour costs.
Architect Dirk du Preez of Grace-
land Architects was taskedwith over-
seeing construction of the Mediclinic
in Kimberly. The project required
10 800 m² roofing structure and clear
spans of 25mwere specified. Roofing

supplier, Central Roof Industries,
installed large shallow pitched Ultra-
Span roof trusses. Timber trusses
were obviously not considered due
to the large spans and the fact that
the roof had to be made of non-
combustible materials.
Trusses were assembled on site
into braced pairs and hoisted into po-
sition on the building in accordance
with a strict time-line of the various
buildings being completed for roof
erection. Each installed roof section
then had special purlin raiser blocks
fitted (to allow for the required thick
roof insulation) in conjunction with
the support wires for the insulation
blanket. This was followed by the
fitment of the LGS purlins into the
raiser blocks before the fitment of
the roof covering of Klip-Lok sheeting.
This method ensured that the roof
sections were in fact fully completed
in appropriate portions and were
accordinglyalso inspectedandsigned
off by MiTek.All the required services
inside the roof void (which included in
some instances the support of medi-
cal equipment) were easily installed
and accommodated. This required
some site alterations but it was easily
and quickly accomplished.
Both the architect and project en-
gineer were impressed by the speed
of completion as well as with the
overall neatness of the roof structure.
The entire 10 800m² roof structure
with a mass of 125 tons of LGS plus
sheeting and insulation was com-
pleted in approximately 14 weeks.
The speed of erection ensured a total
saving of 16% compared to utilising
a hot-rolled steel structure. The roof-
ing structure cost R4,5 million of the
R220 million project.
