ON SITE proper geotechnical investigation — where guys just do back-holes or they do penotrometer tests, which can give you an indication but do not tell you where the rock is. The back-holes only go down three- and-a-half metres, and if the rock commences below that, it doesn’t tell you anything about the rock.” The general challenge with piling is to have the right machine for the job. For this reason, Gauteng Piling owns all its own equipment. In fact, nationally, there are not many machines for hire, “and there are far too many piling companies in the country for the amount of work available at the moment”. Explaining his company’s growth, Haas says that piling is a capital-intensive business, thereby creating a significant barrier to entry. Barrow Construction owns 40% of Gauteng Piling. “When we were getting established in 1996, it was our original intention to overcome the heavy requirement for capital by selling shares to five separate construction companies — but Barrow (through John Barrow Snr) was willing to take all 40% in what was a strategic partnership. It has been a very good partnership for us. This deal enabled us to buy our initial three machines (at current value of R1.8-million each), for which Barrow assisted us with arranging bank finance.” The site is surrounded by established buildings such as Oxford and Glenhove – most of them developed by Barrow Properties. Nico Haas, CEO of Gauteng Piling, with supervisor Victor Mudau on the right. The motivation for the strategic partnership, says Haas, is that while capital is essential in acquiring the costly piling equipment, so too is the need for deep knowledge and experience for each type of area to be piled. “This is possibly even harder to acquire than capital, and my contribution [to the partnership] was my experience in working on all types of difficult sites, including dolomitic sites and on bridges.” He gives the example of cross-border work in Africa, which is popular today but for which Gauteng Piling finds the risks too high. “One can lose a lot of money when working on sites with terrible ground conditions. Especially in the DRC, there are sites where the ground is volcanic ash, and on drilling down five metres it becomes like cotton wool. We worked on one such site, lost a lot of money, and will consequently not go cross-border today.” “The single biggest challenge in piling is having experienced people who understand the conditions and are able to interpret the soil report. However, based on current market conditions in South Africa, the biggest challenges today are getting work at the right price, and then getting paid,” says Haas. nn Professional team The site is about nine metres below ground. 18 | CEC January 2019 Client: Barrow Properties Main contractor: Barrow Construction Architect: LYT Architecture Civil engineer: Kantley & Templar Quantity surveyor: Barrow Construction Geotechnical: Gauteng Piling www.civilsonline.co.za
