2017 FULTON AWARDS At the bi-annual Fulton Awards held recently, the following projects were selected as winners in their respective categories. CATEGORY: ARCHITECTURAL CONCRETE Winner – Zeitz Museum of Contemporary Art Africa (Above) Concrete is the main finishing characteristic of this project which has innovatively retrofitted one of Cape Town’s most iconic industrial relics, namely the Grain Silo at the V&A Waterfront. This original redesign of the interior created new functional spaces for galleries, foyer and pause spaces, exposed staircases, transparent lifts and an administration area. This was supplemented with a new sculptural atrium carved out from the heart of the silos’ existing cylindrical concrete structures. Maintaining the integrity of the old concrete structures and blending it sympathetically with new stabilising concrete work and finishes, this project managed to uniquely reinvent a historical Cape Town landmark. Retrofitting the existing architectural and structural elements such as the silos, with new uses by using bold and dramatic interventions has created a truly remarkable architectural asset. CATEGORY: INNOVATION IN CONCRETE Joint Winner – Van Zyl Spruit Bridge (Below) The unique Van Zyl Spruit Bridge is the first long integral bridge in South Africa and, at 90m, one of the longest integral bridges in the world. The innovative use of integral bridges allows savings in materials, no capital cost for bearings and joints, lower maintenance costs, more durability and makes concrete bridges more competitive. In addition, the installation of over 500 sensors in the bridge structure which are being logged automatically every 15 minutes to detect and quantify trends in strain, temperature, tilt and earth pressure, make this one of the first ‘SMART’ bridges in the country. Joint Winner – Zeitz Museum of Contemporary Art Africa Maintaining the existing structures whilst combining it with innovatively placed new concrete substructures, selective 10 demolition work and recycling make this building a celebration of concrete both as a historical and as a new, innovative building material. Innovative and complex concrete placement and formwork techniques together with a variety of the latest laser- guided concrete-cutting and removal techniques were used. Newly cut and angled edges were polished to expose the original aggregate and steel reinforcement to great effect. This enabled open spaces in which the old and the new stabilising concrete work remain in contrast yet harmoniously fit together. In continuing the theme of paying homage to the silo’s industrial past, the original concrete both externally and internally was cleaned and has been retained as its most visible finish. CATEGORY: BUILDINGS GREATER THAN THREE STOREYS Winner – Sol Plaatje University Library (Above) This bold and original project pushes the boundaries of architect- ural and engineering design, which required very high expectations from the concre te to perform not only as a structural, but also as an aesthetic material. The result is a spectacular three-dimensional envelope which allows a 2.7m wide perimeter void between the external envelope and the floor plates. This resulted in an envelope as an integrated ‘wall and roof’ shell that is functionally, structurally and technically independent of the ‘building’ within it. The contractor managed the unusually demanding staging and shuttering of huge areas of free-standing external envelope walling at the highest possible standards and delivered a highly refined, consistently silky off-steel surface finish. CONCLUSION Glen Crescent House was the winner in the Buildings up to Three Storeys category, and MtEdgecombe Interchange Upgrade was the winner in the Infrastructure category.
