MALL OF THE SOUTH

Mall of the South, located on the corner of Swartkoppies Road and Klipriver Drive, is the new regional mall for the southern Johannesburg area.

• Main entrances to the mall are made prominent by the large glass façades and architectural design. • Outward facing shops along the full length of the building’s façade. • Location of banks/ATMs on the exterior edges to minimise security risks. • Extensive landscaping and green spaces on the upper level parking deck with water features, which are viewed by the restaurant patrons. The indoor environment receives direct natural sunlight filtering through the skylight in the roof. This results in the diminished use of internal mall lighting during the day. The mall is also equipped with a mechanical air conditioning system that maintains an average temperature of 22,5°C throughout the mall, as well as fresh air ventilation. This development has been constructed in accordance with SANS Code of Practice 10142 as amended and complies with SANS 204: 2008 Parts 1, 2 & 3 which states a required Maximum Energy Demand of 90 VA/m² and Maximum Energy Demand per annum of 240 kwh/m²/annum. Taxi bays and taxi drop-off zones were constructed to encourage the use and support of public transport. The bathroom facilities have low flow electronic taps in the wash basins, dual flush cisterns and electronic actuators on the urinals. All tenants and water consumers have been provided with dedicated water meters which read electronically. A stormwater attenuation pond assists in the irrigation of the landscape. In order to re-use and recycle material, the use of Portland cement was reviewed in the approved concrete mixes, and all reinforcement steel utilised on site was manufactured and produced from recycled steel. At its peak the project achieved 5,6 million LTI Free Hours while having more than 4 000 employees on site. The construction of Mall of the South cost over R1,6-billion, with the building portion making up R860-million of the cost. Construction started at the end of November 2013 and the mall opened on 24 September 2015. This 21 month programme (excluding the December shutdown period) was a major challenge due to high production rate requirements, countered by top-end finishes and high quality expectations.

The 22 month construction period saw more than 15 km of augured foundation piles, 60 000 m³ of reinforced concrete, 5,1 million bricks and 17 500 m² of Tilt-Up concrete walls being used. The roof and main façade comprises of 1 000 tons of structural steel, 53 000 m² of Saflok sheeting, 3 100 m² of glass façade and over 7 800 m² of detailed aluminium composite panel cladding, resulting in a 200 m wide, curved entrance feature that can be seen from quite a distance away when travelling towards the mall. The external works, surface parking and landscaping, added to the mall and parking, combined to a total construction area of just less than 275 000 m². Mall of the South was designed and built using precast Tilt- Up walls around the perimeter of both retail levels. These walls, although not as cost effective as the standard brick and plaster façade build, assisted the programme in enabling us to close the shop envelopes quicker, by erecting twelve to fourteen 11 m high x 10 m wide panels per day. This is in comparison to building 1 430 m² of plastered façade brickwork in a day. The longevity and low cost maintenance is a further benefit that these Tilt-Up walls offer the client. The good quality off-shutter finish further reduced the amount of painting required in the back of house and delivery yard areas. The Mall of the South design brief was conceptualised as a double level, enclosed regional mall with specific attention being given to the following areas: • A continuous skylight running along the entire roof scape of the building. • Wide walkways and generously sized public areas. • The unique shape of the mall’s layout maximising the extent of the shopfronts. • Central double volume forecourt which will be used for mall entertainment.
