The main challenges posed by the project were varied floor heights, and a façade that integrated steel, glass, aluminium, and concrete elements. The 1.8-m-wide and 300-mm-deep ‘feature brow’ along Pybus Road was a suspended off-slab edge with a 33° column-line angle.
It extends from the 2nd to the 6th floor, returning at the 6th to the 9th floor. In addition, a ‘small brow’ along Rivonia Road is a cantilever feature from the 2nd to the 4th floor, protruding from the slab edge at a 40° angle, and returning into the horizontal slab on the 4th floor.
The main contractor was WBHO, which has collaborated with PERI South Africa on a range of iconic projects, from the new Discovery Campus head office to Alice Lane 3, both in Sandton. Other professional team members on 92 Rivonia Road were DBM Architects, L&S Consulting as structural engineer, and Cadcon as specialist steel fabricator.
“Basically, we were involved from the tender stage,” Lead Engineer: Key and Strategic Projects Sebastian Burwitz points out. This is because WBHO already had an extensive selection of PERI equipment in their yard, which was then supplemented with regards to project requirements.
The individual components are lightweight, with the panels and main beams weighing only 15.5 kg respectively. This allows for a systematic assembly sequence whereby the size of the panel dictates the prop position, with only 0.29 props required per square metre of slab formwork.
PERI South Africa’s scope of work focused on all of the horizontal concrete elements, such as the two feature brows, which had to be integrated seamlessly with all of the steel, aluminium, and glass elements. “In terms of our specific relationship with WBHO, we are responsible for most of the project designs where our equipment is utilised,” Sales Representative Andries Ysel stresses.
In the end, the 3D model was the only way to visualise, and resolve, the full complexity of the feature brows. “It enabled us to develop the best solution for the client in a virtual space. It is also an integral part of the added value we are able to bring to an iconic project such as this.
“There is a major trend towards Building Information Modelling (BIM), which transforms a 3D model into a ‘smart’ design that can be linked to checklists and even animations. The client now has access to such interactivity on-site through any smart device, and can flag any problems or issues for our experts to attend to, or to provide any technical assistance required. This is definitely the next level that the construction industry is moving towards,” Ysel concludes.
