façade, randomly scattering façade panels and making spandrels
non-reflective. In the end, it was decided that the best solution
was to use a less reflective glass in the spandrels that was further
enhanced by acid etching. Landscape shading addressed any
remaining concentrations over limit.
Stormwater management
Careful consideration has been given to mitigate the risk of
flooding. Utilities provision has been considered and a storm
water management plan has been prepared to inform the SDP
submission as well as the LEED assessment.
Conclusion
The PwC Tower, when complete, will be exemplary. Not only will
its striking profile be recognisable from many kilometres away, it
will also stand testimony to the skill and innovation found in South
Africa’s built environment fraternity.
Lawson gives Arup’s highlights of the design: “Our use of
parametric modelling software on a project of this scale is unique
within South Africa. By taking this approach we realised both time
and cost efficiencies and a better integrated and well considered
design, with all architectural and construction factors in sync.
“Because tall buildings of this scale are no longer the norm
in South Africa, the team had to consider appropriate current
methodologies and technologies throughout design. We believe
this project highlights one of Arup’s founding principles – that of
holistic design. The PwC tower is being made possible through
industry collaboration and the embracing of technology to
facilitate that collaboration”.
