2018 april franki coverON THE COVER: Once complete, Pinnacle Towers in Nairobi, Kenya, with a height of almost 300 m, will be the tallest building in Africa. For Keller company, Franki Africa, which is in the process of doing the geotechnical work, this prestigious project has been somewhat of a milestone.

The building, in Nairobi’s Upperhill area, will cost an estimated USD194-million, and consists of two towers. The tallest will have 70 mixed-use floors and the other will be a 45-floor Hilton Hotel developed by Hass Petroleum and White Lotus Group. There will also be 200 apartments run by the Hilton Hotel that will include one-bedroom, two-bedroom, and three-bedroom fully furnished luxury apartments.

While promising some hope for improved economic growth, leading economist Dr Azar Jammine said the government’s recently unveiled budget will not bring any quick relief to South Africa’s struggling civil engineering and building sectors.

Richard Tomes, sales and marketing executive AfriSam, highlighted Dr Jammine’s point that fixed capital formation needed to be about 25% of gross domestic product if it is to really promote a sustainable growth path. “We are nowhere near that figure, in fact, we are not even at 15%,” says Tomes.

Footbridges are built to improve road safety for pedestrians and motorists. First and foremost they must be functional and low maintenance structures. There is, however, the question for designers of whether they can be more than that. “Footbridges of unique character can fit into any environment and add a pleasing quality to such”, states John Anderson, SMEC’s Functional General Manager for Structures, based in Cape Town.

Terraforce recently supplied product for a retaining wall in the Western Cape. This large retaining wall is located on the West Coast, Pepper Bay harbour area, to stabilise existing eroded embankments in the interest of public safety. The embankments consist of multiple layers of sedimentation up to 21 m in height and 2,5 km in length, where softer material has eroded leaving harder layers of overhanging and unstable rock.

The Centre of Product Excellence (CPE) at construction materials leader AfriSam has been reaching out to support the sustainability of smaller players in concrete product manufacturing, thereby enhancing local economies and helping create jobs.
