The single speed smoke exhaust fan, kitchen hood fan,
toilet extract fan and FA fan coil air handling unit (AHU)
will also have the same specifications.
Throughout installation, 52 Engineering employed local
SMMEs and although challenging at times, it was a great
learning experience for all parties concerned.

BUMPS IN THE ROAD
The project was scheduled to run from 2014 to 2017, but
after the main contractor went into business rescue, the
project was on hold for close to year. 52 Engineering was
affected but they managed to get through the period
with the strong working relationships they had with
their creditors. They were re-awarded the project in June
2019 with a new main contractor, Enza Construction
running the project. Enza Construction, a level 1 BBEEE
company, although only 15 years old has roots going
back nearly 40 years as Crowie Builders. So far, the
project is running smoothly and is expected for handover
in the first half of 2020.
As president of SARACCA, the association is made up
of contractors who have individually and jointly agreed
to a set of governing standards whilst operating in free
competition against each other. The common aim is to
continually strive to improve the image and standards of
the industry and the association provides a forum for
this purpose.
COMPLETED WORKS
The interchange will be used for 20 cross-border buses
at a time and 158 interprovincial taxis. It will also
accommodate a further 684 holding taxis. The intermodal
hub will cover about 3 000m 2 of retail space, anchored by a
well-known retail outlet, and there will be space for 163 stalls
for informal traders. RACA
