Arup was the structural consultant responsible for achieving the iconic twist in the tower
as well as designing the façade. The project was submitted for consideration by Afrisam
and CHRYSO SA.
Richard Lawson, associate director at Arup and project manager on the PwC Tower
said, “We are delighted to have shared in this Commendation by the Fulton Awards
judging panel, and we congratulate the client Attacq Waterfall Investment Company and
LYT Architecture, together with Afrisam, CHRYSO and all contractors who are involved
with the project. For the Arup team, this has been a major achievement in twisted
building design, and we are exceptionally proud”.
The judges’ citation highlighted that “the design solution balanced gravity loads on
the corner columns and reduced the torsion on the core of the tower, making stresses on
the core wall decrease by a factor of four. This meant that the structure used a 450 mm
core wall that is a similar thickness to what a typical straight tower of that height would
have needed. By taking this approach, both time and cost efficiencies were realised
resulting in better integrated and well considered design that satisfied the architectural
vision of the building and space planning constraints”.
Afrisam is one of South Africa’s leading suppliers of construction materials and
technical solutions, and the main concrete supplier on the PwC Tower development.
CHRYSO Southern Africa formulates, manufactures, sells and distributes admixtures
and additives that service the cement, readymix, precast, new construction, mining and
gypsum industries.
