The Tower in Waterfall, located in Midrand, is the new headquarters building for PwC in South Africa. Owned by Attacq and developed by Atterbury, the R1.5 billion Tower is the first high-rise building developed within the booming Waterfall precinct, as well as the Midrand-Kyalami district.
The Tower is an iconic 27 storey building that comprises 25 storeys of modern office space, five parking basements, designed to house 3 500 PwC employees in an efficient and optimally designed workplace. The headquarters also includes an annexure building onsite that comprises of numerous office floors, conference facilities, meeting rooms, commercial kitchen and canteen facility, recording studio, and archive rooms. The total development is around 48,000m2.
Developed in a prime location, the Tower overlooks the Waterfall City Part and the Mall of Africa. With its unique design, the height of the Tower and the fact that it is situated on a high point in Waterfall make it the tallest structure on the corridor between the Sandton and Pretoria/Tshwane CBDs.
Visible from almost anywhere within a 30km radius, the Tower gently twists through in height with the top and ground floors rotated by 30 degrees – framing the grand urban park, which forms the green heart of Waterfall. The Tower has also been designed to conform to the internationally recognised LEED (Leadership in Energy and Environmental Design) silver standard. LEED is a set of rating systems for the design, construction, operation, and maintenance of green buildings, homes and neighbourhoods.
WSP was appointed as the mechanical consulting engineer on this project for heating, HVAC design, building management systems (BMS), as well as energy monitoring systems (EMS).
The air conditioning for this building has been designed to be commercially economical, while maintaining good occupancy comfort and thermal zoning. This has been achieved through high operational efficiency, and high coefficient performance (COPs) of the cooling and heating systems, with state-of-the-art chillers and an integrated heating and cooling recovery system.
