SAISC0163 Steel Awards 2009 – all the winners Dr Hennie de Clercq, executive director of the Southern African Institute of Steel Construction (SAISC), which recently hosted Steel Awards 2009, said the entries – a record number this year – reflected the outstanding quality of the local steel construction industry in all its diversity. “We congratulate the winners but emphasise the exceptional quality of all the entries, which augur so well for the future of our industry,” he said. Steel Awards, held on the 3rd September 2009 at the Vodadome in Midrand and simultaneously at the Sun Coast Casino in Durban, was hosted by the SAISC with DSE Structural Engineers and Contractors (DSE) the main sponsor. Moses Mabhida Stadium – Overall Winner In announcing it the overall winner the judges said that the Moses Mabhida Stadium (Durban’s 2010 soccer stadium), named after Durban’s iconic working class hero, was a statement of international prestige. “Built to the highest international standards this steel structure is every bit a world winner,” they said. As with all iconic stadiums, the central engineering and aesthetic element of the Moses Mabhida stadium is its roof structure, which consists of five structural elements – a major steel arch, supporting cables, a membrane roof, and a steel compression ring resting on steel columns. The 350 metre long and 106 metre high (at the pitch) free-span arch, consisting of 56, 5 x 5 m steel hollow boxes and weighing 3500 tons, was fabricated in Germany and shipped to Durban in sections. The magnitude of this arch is such that a cable car will carry visitors up the SAISC0163 composite -2- middle of it, to a viewing platform on its north side, while the south side will have a 550-step adventure walk. The compression ring, the structure to which the roof elements are linked, is supported on a series of vertical and inclined structural steel façade columns comprising 102 boxes fabricated from steel plate. Repeated testing was a strong feature of this project and to achieve the required accuracy for the complex geometry, four compression ring elements were bolted together in a trial assembly simulating the unstressed geometry. “The fastidious attention to detail and the meticulous testing thereof were a major part of this project’s success,” said the judges. This project was one of the most complex sets of steelwork DSE has ever produced in its workshop. “They overcame all of the significant challenges they faced,” said the judges, “and, in so doing, produced innovative and creative thinking and a roof structure that works like a ‘Swiss watch’”. “The Moses Mabhida stadium is a formidable and awe-inspiring work of genius of which South Africa and the world will be proud for generations to come,” they concluded.

The judges were unanimous that this building was an outstanding illustration of the aesthetic use of structural steel in the development of industrial buildings. “This pioneers a new generation of industrial buildings,” they said. “The first impression when arriving at the premises of ‘Gottlieb House’ is one of a structural steel warehouse, situated high on the natural hills of Kwa-Zulu Natal designed by an architect who loves the aesthetic feel of exposed steelwork and is great at making it work,” the judges said. The ‘room with a view’ reception is an excellent example of exposed steelwork complimented by coloured and clear glass in diagonal panes. This area also has a striking steel staircase, illustrating the architect’s appreciation for using the right material in the right place. The judges stressed that, apart from its aesthetic and functional brilliance, it was the pioneering use of steel in an industrial environment that won this project the prize. “Should other industrial enterprises follow the example of the Gottlieb offices and distribution centre, the entire aesthetic face of South Africa could undergo a radical change,” they concluded. Gootleib House Project Details Developer/ Owner: Winsport Trading Enterprises (Pty) Ltd Architect: Elphick Proome Architects Structural Engineer: Young + Satharia Quantity Surveyor: Aybob Ismail and Mohamedy SAISC0163 composite -4- Project Manager: Arbuthnot Projects Main Contractor: Stefanutti Stocks Steelwork Contractor: Impact Engineering Land Surveyor: LD Baker and Associates, Cellular beams: Macsteel Trading Breedezicht Estate – Light Steel Frame Building Award In a year when the number of entries in this category grew significantly, it was not a single house that stood out from the rest but rather three houses in the same estate –the Breedezicht Estate in Witsand, Western Cape. “The award-winning houses showed professionalism comparable to anywhere in the world. Their finishes are incredible with straight and level lines and vertical and square corners. Add to this the simplicity of running services in a cavity wall ready to receive them and in double- quick time and this project demonstrates, in a world class fashion, one of the most exciting building technologies for the future,” the judges said. The judges were suitably impressed by the efficiency of LSF home building. “Breedezicht amply demonstrated how the LSFB system produces a home of exceptional strength and solidity whilst affording easy, fast and accurate installation. “ The double-storey luxury house on Stand 1090, erected on a standard engineer-designed slab, took only four months to complete from start to finish while the Vermont style, single-storey on Stand 1081, took only three and a half months to complete. LSFB was also very suitable for this area said the judges. “A minimal amount of waste was generated by this project while the amount of dust, SAISC0163 composite -5- grinding, residue, off-cuts, water usage and pollutants were reduced to a minimum.” The judges said that the overall project was outstanding. “The standard of finish was excellent, the homes have the most stunning views and all this was achieved cost-effectively, the cherry on the top in a truly brilliant construction project,” concluded the judges.

Steelwork Contractor: Light Frame Homes Highveldt House – Residential Award Highveldt House won the Residential Category. The judges said that this project’s outstanding achievement was the incorporation of steel as primary construction element in a residential setting fully integrated into a protected, natural and unspoilt environment. Highveldt House is set in a typical South African Highveld environment, within the ‘Cradle of Humankind’. The house is designed as a series of pavilions arranged between the horizontal planes of the floor and the roof. These planes are located within a section of a stinkwood forest, on the edge of an intrusion of veld and are elevated above natural ground by an ‘apparently randomly measured forest’ of skew columns - 2 legs per column - to give the feel of tree trunks. SAISC0163 composite -6- The judges were particularly impressed with how steel was used in this project saying that despite the many advantages of steel as a construction material, it has not been extensively used in the South African residential sector as a prominent construction element. They added that Highveldt House demonstrates clearly how warmth can be created with steel. “The juxtaposition of steel columns and rafters, clad in timber, framed in glass and successfully integrated into its environment has created a warm and homely atmosphere.” “This project could pave the way for showing the ‘steel objectors’ that steel can easily be part of a successful solution, in a variety of settings, including sensitive public spaces, in the construction of warm, beautiful homes,” concluded the judges. Highveldt House Project Details Architect: Van der Merwe Miszewski Architects (Pty) Ltd Structural Engineer: WSP Structures Africa (Pty) Ltd Quantity Surveyor: Turner & Townsend (Pty) Ltd Project Manager: Turner & Townsend (Pty) Ltd Main Contractor: IQNC Imagine Construction (Pty) Ltd Steelwork Contractor: Cosira International SA (Pty) Ltd Rio Tinto QMM Ilmenite Project - Export Award Fort Dauphin, on the south-east coast of Madagacar is a challenging location. “The discipline of this project team and its unique ability to succesfully complete a project of this nature in a very remote area contributed to this project being a clear winner,’ said the judges when announcing the Rio Tinto QMM Ilmenite project the Export Category winner. SAISC0163 composite -7- Apart from the direct, and significant, challenges to logistics and construction, great care had to be taken of this area’s sensitive ecology. As such, the protection of the island’s unique fauna and flora were as much a priority for the project as the usual elements like health and safety. Despite these challenges the project logged a world class safety performance with a frequency rate of 0.07 and 12 million hours worked without a lost time injury. The judges noted that this is testament to the degree of co-operation and co-ordination that existed on this project, which was vital to its ultimate success. The wet plant was built on special pontoons which were sourced from China. The pontoons were shipped to Tamatave and then transferred to barges – sixteen 7.8m wide x 3.7m high x 21m long pontoon modules were barged 700km south in four trips. The plant towers above its surroundings to a height of 33m at its highest point and is anchored against severe wind conditions by four large winches at its corners which also render it manoeuvrable in the extraction pond. The statistics for this almost surreal project speak for themselves with the plant boasting the following material tonnages: pontoon mass 1888 tons, structural steelwork 1582 tons, equipment 1347 tons, material and water 2800 tons giving the plant a total mass of 7617 tons under normal operating conditions. The judges said that exports require extraordinary discipline, planning and sometimes almost indescribable execution skills. “This project demonstrated all these skills abundantly,” they said.

In the upgrade, the western stands were increased in capacity necessitating the removal of the existing tubular steelwork to make way for the new stand extensions and roof covering. The capacity of the ground was increased from 39 000 to 45 000 seats. Amongst the many complexities of the project were the nodes above the under-slung steel sheeting. Each node is a ‘multi-faceted’ meeting point for the columns, the roof rafters and the horizontal bracing and tie members. The judges commented that the nature of football stadiums almost invariably dictates elliptically shaped roof structures and that the Royal Bafokeng stadium is no different. “This means the angles of the bracings connecting into the nodes vary in every bay. The end result is that all 32 nodes are unique and different from every other node.” They also noted that every purlin is its own small masterpiece with each length and each end-bevel unique. SAISC0163 composite -9- The judges said that the careful planning for this complex project was palpable. “The effort put into the detail made a significant impression,” they said. “From the design, through to the fabrication and erection, this project is testimony to the world class expertise of our local professionals,” they concluded. Royal Bafokeng Project Details Developer/ Owner: Royal Bafokeng Administration Architect: BSP Architects Structural Engineer: M2 Consulting Engineering (incorporated into VelaVKE Consulting Engineers) Quantity Surveyor: CP De Leeuw Project Manager: CP De Leeuw Main Contractor: Liviero/ Wramatshe JV Steelwork Contractor: Midmar Engineering (Pty) Ltd Galleria – Tubular Award Inspired by the design of the iconic Second World War Vickers Wellington Bomber, the roof of Galleria in Melrose Arch has won the Association of Steel Tube and Pipe Manufacturers Tubular Category Award. The ‘Melrose Arch Offices and Shopping on the Piazza’ scheme was conceived as a return to the ‘High Street’ shopping experience. It was with this design ethos in mind that the challenge of realising the Galleria as an open, but covered street was tackled. An initial scheme for a glazed roof was deemed too ‘mall-like’ and so, sparked by Barnes Wallace’s geodetic lattice structure, which he used SAISC0163 composite - 10 - for the Vickers Wellington Bomber, the design team set about realizing this unique, glazed tubular steel canopy. The desire for a continuous, seamless solution required innovation geometrically, technically and in the procurement process. “The result was a highly innovative construction methodology and a custom- designed aluminium glazing system,” said the judges. The judges said that despite challenges such as unforgiving glass panels, the curved shape of the roof, rain water accommodation etc, the team came up with an innovative roof that is both functional and highly aesthetic. “This project was an outstanding demonstration of how tubular steelwork can perform when creatively and innovatively put to the challenge,” they concluded.

The project involved the total refurbishment of the old FNB Stadium into a 90,000-seater. The scope of works included 120,000m³ earthworks, 65,000m³ concrete, 7,500 tons reinforcing steel and 7,500 tons structural steel. “This, in combination with the erection of 28,000m² fibre-reinforced façade panels and 54,000 m² of PTFE roof and ceiling membranes onto a complex three dimensional double curvature steel structure, has resulted in this stadium being transformed into one of the most striking, impressive and well-equipped stadiums in the world,” said the judges. Like with most modern sports stadiums, the roof of Soccer City is its most important and interesting element. Constructed mainly in steel this roof not only expresses the symbol of World Cup 2010, it also showcases the flexibility of steel through its curved shapes and radial arches, which form the central design element – the calabash. “The calabash was a most appropriate choice for the shape of the showpiece of the 2010 World Cup. The integument is defined by earthy, African colours, and an almost animal hide-like tightness, while inside, the stadium springs powerfully to life.” “From a steel perspective the deep overhanging roof and capacious circulation spaces are testament to the ability of steel to span large distances; and if sports stadia are the cathedrals of this age, then steel has contributed much to that sensation,” said the judges. SAISC0163 composite - 12 - “The sheer enormity of this project and its success as a symbol of Africa will boost the image of South African skill and expertise for generations to come,” concluded the judges.

The judges explained that the headgear was designed as a dual purpose headgear to be used for sinking and equipping condition and the SAISC0163 composite - 13 - permanent hoisting condition. “In its permanent condition it will be used to hoist two 31 ton skips, one double deck man/ material cage with its counterweight, and a double deck service cage with its counterweight.” In terms of the use of steel on the headgear, the judges noted that some of the unique features of the headgear were the extensive use of tubular sections for bracing members, cruciform plate girders for columns and the size of some of the beams. The judges said that it was an unadulterated pleasure visiting this site. “From the offices to the safety briefing, from the loaned gumboots to the highly technical details for the project itself, one knew one was dealing with a highly professionally planned and executed project,” they concluded.
