PROJECT INFORMATION

• Company entering: WBHO • Project start date: 19 August 2019 • Project end date: 26 November 202 0 • Client: Atterbury Properties • Main Contractor: WBHO • Architects: Boogertman + Partners Architects • Project Manager: Boogertman + Partners Architects • Quantity Surveyors: Norval Wentzel Steinberg • Consulting Engineer: DG Consulting Engineers

The parking area consists of 1 174 parking bays over an area of approximately 29 500 m 2 and facilitates a market from time to time that ties in to the central open food court between the contemporary industrial, farm style restaurant blocks. The construction of the retail centre took 14 months in total (Including a three month lockdown) and consumed approximately 8 500 m 3 of concrete as well as roughly 400 tons of reinforcing. The retail centre is comprised of six blocks, four of which have anchor store’s located within the blocks. The individual blocks are connected with external walkways and a central open air park area surrounded by concrete and steel trees that support the external walkway canopies. All façades were constructed with a locally sourced and manufactured face brick. Wall panels constructed include standard stretcher bonds to curved, ventilated Flemish bonds. The central tower is cladded in a ventilated Flemish bond face brick and represents an old industrial style brick factory chimney with exposed steel beams that tie it together. The internal structure of the tower is made up of four concrete columns rising to a height of 18 m with two internal slabs to house air-conditioning plant for the tenants below. The top of the tower holds a structural steel box cladded

in aluminum and glass. The entire tower is illuminated in the evenings. Over 125 m of 3 m high off shutter concrete retaining walls were constructed on the northern perimeter of the site. This also included eight 12 m off shutter Class 1 concrete signage pylons with LED lights. These columns were cast in a single lift and the team made use of high frequency internal and external vibrators to ensure a high level of quality in terms of the concrete finish. The catchment area of the roof structures totaling 26 850 m 2 feeds the concrete gutter slabs that in turn act as a catchment and channel for storm water off the main roof structures and feed a 100 000 ℓ capacity stormwater harvesting and water filtration plant that supplies potable filtered water to the retail centre. The location and geology of the terrain added a challenge with regards to the design and installation of wet services
