Haw & Inglis Civil Engineering ( Pty) Ltd July 09 www. bus- ex. com 73 the upgrade of one of the busiest interchanges in Cape Town, but without any disruption to that traffic. " It's tantamount to performing open heart surgery on Cape Town's traffic aorta", comments Chemaly. Strangely enough the interchange is adjacent to the famous Groote Schuur hospital where the world's first heart transplant was performed. Visitors to next year's World Cup will be looking forward to taking in some of the popular tourist destinations around Cape Town. H& I is feverishly installing upgrades to the rockfall protection and remediation measures on one of these attractions, the world- famous Chapman's Peak Drive. The road around Chapman's Peak dates back to the early 1900s and was built around the coastline by prisoners of war. Just like Robben Island, Chapman's Peak is a tourist must, with unparalleled vistas of the peninsula. Unfortunately, the road was built on the back of a mountain with steep, unstable slopes. Four years ago H& I completed restoration work which called for the world's largest concentration of alpine safety nets and catch fences supplied by the Swiss firm Geobrugg. At times, the only way the fencing could be installed was through the use of helicopters and abseiling ( rappelling) construction workers. But H& I seems to relish challenges. In fact, it deliberately H& I takes on all manner of roadworks, from brand- new virgin highways to patch and repair. It has expanded the company's capacity and expertise by acquiring a specialist concrete construction company, which immediately opened up more opportunities to tackle a greater variety and complexity of projects. " With this acquisition we have gained valuable expertise in ' high- tech' concrete structures," says Chemaly. " One of our flagship projects post this acquisition is a marine quay wall and boat yard for the country's special forces. We also have a building company which has established a reputation for quality work in the hospitality industry". The business also has its own crushing facilities, with five mobile crushers producing gravel. South African road pavement technology has developed designs which employ high specification graded crushed stone layers, which are overlain with thin layer asphalt, or stone chip surface dressings. Chemaly says that road surfacing technologies have been developed in South Africa which can be as thin as 15 millimetres, thus making road construction far more economical for this cash- strapped country. At present, all stops are out completing three major road projects in time for the World Cup next year. The Hospital Bend upgrading project is particularly challenging, as it entails
