PROFILE and it is exceptionally arduous work, involving 12–18 hours a day of laying dangerous charges. Because of the paucity of skills — and the dearth of demolition projects in South Africa — Perkin describes it as a dying domestic industry. Consequently, much of the work won by Wreckers Dismantling is outside of South Africa. Veterinary’s loss Demolition was not Perkin’s first choice. He had planned on being a vet but was discouraged by the seven years’ study, as he wanted to work and earn a living immediately. Though he never initially sought out the demolition profession, he has remained in it for over 50 years due to the satisfaction it offers. “You get enormous gratification from planning, executing, and bringing off the destruction of some infrastructure without causing damage.” When pressing the ‘go’ button, he gets as nervous today as he did on his first-ever implosion. “Working with explosives and detonators is not something you can ever take for granted, as there are still many unknowns.” He has had a couple of occasions out of the hundreds he has carried out when towers or buildings only partially collapsed — usually because there were water pipes or ducts within concrete columns he had not been aware of and that had misdirected the blast. The first time took him by surprise (and Africa is the only place he has ever heard of that has pipes within columns), but he has since learnt to check. One of his most recent projects in Abuja, Nigeria, had a similar problem. The solution was to locate the pipes during drilling, which were then filled with concrete, and then had to be re-drilled — something that took additional weeks. “We had to fly up two tons of explosives — but seeing the structure collapse with no damage at all made it all worthwhile,” Perkin says. Where his heart is, is filling holes with explosives; work so dangerous that the only other person he allows to touch it is his son. That is because he trained his son Kyle himself, who is now the youngest qualified explosives engineer in South Africa for demolition. In the Abuja project, there were 10 000 such holes. metres up a tower manually. I prefer implosions to be kept low-key. Making a public spectacle of demolition increases the safety and crowd control risks. Explosives are just another tool available to the demolition engineer.” Apart from bringing down all types of structures, Perkin says his other passion is teaching others the fine art of wrecking. In an industry suffering from a debilitating skills shortage, he has trained 10 of his key staff members to be the top of their trade. nn Because of the paucity of skills — and the dearth of demolition projects in South Africa — Perkin describes it as a dying domestic industry. No crowd pleasing please Internationally, demolition has become something of a TV and Internet spectacle, but Perkin says imploding structures and any form of explosives work is only 10% of the work in demolition. “For the rest, most of the work is out of sight, often done 50 CEC August 2018 - 31
