TECHNOLOGY T he cost of formwork for reinforced concrete constructions accounts for a significant share of the cost for the building shell. Studies show that between 30% and 40% of the cost for the overall shell construction of a reinforced concrete building is spent on formwork (Müller, 1972; Rathfelder, 1992; Hoffmann, 1999; Reichle, 2002; Girmscheid, 2011). Dirk Odendaal, a director of RMD Kwikform, says a noticeable trend for larger companies is to bid for smaller jobs than what would have interested them in the past — such is the dearth of projects. “RMD has traditionally had a greater footprint in the civils space, but in recent times we have seen the building sector of formwork outperforming.” The increased number of formwork companies tendering for a decreasing number of available projects has driven down the price — and margins. RMD Kwikform has always tendered for both small and large projects but has responded to the downturn in construction and the economy by addressing the skills shortage in the country. “The skills level at contractor level is declining, as smaller contractors cannot afford to retain highly skilled people and so subcontract the labour. They have essentially become more project managers than contractors. In South Africa, most people do not have access to trade schools and most people learn on-the-job. Therefore, retaining skills when skills are not retained in the business is a challenge. We offer training to erect our own products, and we make it as easy as possible for unskilled workers,” says Odendaal. “We have also established a pre-assembly factory where we do www.civilsonline.co.za pre-assembly for contractors so that it can be sent on site pre-assembled.” He explains that the drive for formwork is found in easy-to- assemble products. “These may appear to be more expensive, but when one factors in the time and labour saved in assembly, they are in fact cheaper.” Louis Pieterse, MD of specialist formwork company Staluform, explains that it was for that very reason that he opted to specialise, as the barriers to entry were much greater. “Any man with a garage and three welders can really do formwork — but in our niche, the margins are much higher and the need for skills creates an enormous barrier to entry.” It is, for instance, the only company in the country that makes Dolos moulds for breakwater and harbours, which it sells worldwide, as well as being the only South African company to make heavy-duty 30kg Newton props. That doesn’t make it easy. Much of his work is in making forms for bridges and road barriers, and the lack of tenders from Sanral has reverberated throughout the construction industry this year. He has noticed a slight pick-up in work recently and is confident that a considerable amount of work remains that must eventually be undertaken — this backlog of work is likely to come to market during 2019. Private sector work has dried up for several reasons: two years of political uncertainty has taken its toll on investor confidence, and land expropriation without compensation has been the final straw. Businesses are holding back on developments until they have certainty about their land title. “Because 90% of our work is in CEC November 2018 | 23
