FEATURES The use of wood as a structural material adds various benefits to roof design and is on the rise. The key benefit for clients is a far more intuitive understanding of their projects than is possible by looking at a traditional 2D drawing. “Until now, we have used a 3D model displayed on a computer screen to boost our clients’ understanding of a project. VR takes this a natural step further, as it places you literally within the ‘as built’ project,” Howie explains. AECOM now offers 3D models as standard across all of its projects, even though this is not, as yet, a contractual obligation in the local construction industry. “While the digital revolution is being driven largely by the engineering, design and consulting fraternity, with contractors perceived as ‘old school’ and being dragged along in their wake, AECOM is working closely with a number of contracting companies that have expressed interest in latest innovations. 22 JAN - FEB 2019 CLADDING // CONCRETE // INSULATION // STEEL // THATCH // TIMBER // TRANSLUCENT // WATERPROOFING // COMPONENTS “The successful uptake of such cutting-edge technology by AECOM locally has even resulted in the South African team making a substantial contribution to the BIM modelling for large international projects. Not only do we have world-class engineers in South Africa, but our level of BIM knowledge and expertise is equally exceptional at the top level, to the point where we are receiving major international recognition,” says Howie. However, the uptick of adopting new technologies and methodologies is somewhat slow locally. “The roofing and construction industry have come from a very conservative background,” says JD Botha of Biligom International – the innovative business behind the patented process of using moist eucalyptus to produce structural timber. Botha says it was very difficult for Biligom to include a new structural timber technology into the market. After a lot of sweat and educating architects, engineers, quantity surveyors and governmental institutions, it must be said that we are now picking the fruits, he notes. Timber takes centre stage Regarded by the timber industry as a sound and well performing resource in construction, the use of wood as a structural material adds various benefits to roof design and it is on the increase. Its availability, sustainable traits and workable nature turns timber into an efficient and attractive raw material of choice. Unlike steel and concrete, timber is a renewable resource in abundance in South Africa. He highlights that far more timber www.saroofing.co.za
