THE CHALLENGE

Looking out over the construction site for the Kusile Power Station, about 100 kilometres northeast of Johannesburg, South Africa, Gerrit Griessel sees a lot of work to be done. “Our part of the project is roughly in the region of 1.7 billion Rand [$130 million USD]”, explains Greissel, “we are the main building contractor on site. It’s a very, very challenging project with lots of constraints.” The Kusile Power Station was one of the largest infrastructure projects under construction in the world. On a worksite covering over 3,300 acres, the project employed over 17,000 workers and was the single largest stimulus to South Africa’s national economy at the time. Completed in 2018, the power station provides just under 4,800 MW of power, representing 12% of the country’s future generating capacity. “The challenge that we faced with getting the mortar and plaster to the buildings on time, and having fresh material available for the construction was a huge constraint. The conventional method of batching it in normal fashion did not suit the project”, he says. The rural setting of the job site made the logistics of obtaining material a major headache, especially fresh, quality concrete. With the project running significantly behind schedule, Greissel and his team looked for a better solution.

THE SOLUTION

Greissel explains, “we looked at a couple of options and eventually we settled on the ProAll Reimer Mixer. It has proved to be a huge success. We managed to bring down the quality issues we had on getting the material on site”. Beyond increased quality and reliability, the Reimer Mixer also helped the crews’ efficiency. Work was able to begin a full two hours earlier, and standing time was significantly reduced. “We improved productivity with our labour force about 75%, with them not standing without material on site”, estimates Greissel. With such a massive, complex project to oversee, Greissel is glad he can cross concrete supply off his list of worries: “probably the biggest advantage of having the Reimer Mixer is having the right product at the right time in exactly the right quantity“.
