PEPKOR DC WAREHOUSE “ W e achieved very high natural light levels in the warehouse through the use of strategically placed translucent sheeting in the façade of the warehouse. The form of the warehouse and the roof design optimise the natural air flow through the warehouse. Both of these design features make the warehouse very energy efficient as well as a relatively comfortable workspace. LED lighting was used throughout the facility. Another sustainable initiative included harvesting stormwater for use in the toilets, urinals and landscaping,” Thornhill pointed out. Specified 4mm white Alububble® 2906 radiant barrier achieved the necessary thermal insulation performance criteria. A total of 2500 tons of structural steel was erected (Main warehouse 2180 tons and canopies / offices 320 tons), with the erection commencing on 14 November 2016, the project was recently completed. Roofed and cladded with a high tech, premium grade of coated steel that provides not only long life in service but also an attractive finish. The building features the innovative usage of steel on many levels. According to GD Joubert of EDS Engineering Services, “The warehouse offers a mixed use area of 82 000m 2 consisting of covered warehouse space – 440m x 180m – also providing office spaces of 3 000m 2 and 1 800m 2 for companies Ackermans and Speciality and a total of a further four node offices each of 500m 2 each”. “The brief called for approximately 17.35m clear height to underside of eaves. Materials consisting of reinforced concrete and structural steel according to structural engineer’s design with appropriate corrosion protection where necessary. It was envisaged from the outset that the warehouse would be constructed largely of structural steel. The main support columns of the warehouse are concrete up to 12.6m and 17m from FFL. The remainder of the structure was constructed from structural steel. Structural steel was strengthened locally to allow for the installation of solar panels to a roof area of approximately 15,000m 2 ”. Roof type “The structural system used for the building was based on a girder truss system carrying lateral trusses that makes up the main elements of the roof. Various steel profiles were used for the building, including the structural , roofing and cladding elements”, says Joubert. AFRICAN DESIGN MAGAZINE © | JUNE 2018 33
