Two decades of trenchless technology

This year, Trenchless Technologies celebrates its 20th anniversary in the directional drilling and pipe rehabilitation industry, which indicates a certain tenacious faith, Trenchless Technologies’ Sam Efrat tells Chantelle van Schalkwyk. “One needs to be extremely tenacious and have a great deal of faith in order to overcome the many challenges one is faced with over the years. Trenchless Technologies is in business because from inception we managed to fill a need in the market to provide viable solutions and alternatives to conventional open-cut pipe laying,” says Efrat. Trenchless Technologies was registered in 1991 and in May 1993 commenced operations with a 3 t truck, a compressor, two earth piercing tools and some R80 000 in capital. “We began operating out of a studio at the back of my house in Berea, Johannesburg with five employees. Today, we have over a 100 employees, many of whom have been with us for 10 to 20 years, through ‘thick and thin’,” explains Efrat. Growth &... Read More

Infrastructure ambitions for the medium term

By Thabo Manyoni, executive mayor of Mangaung 2012 was a great year for Mangaung in the sense that we claimed our space as the heart of South Africa. As a city, we believe that it is our mandate to deliver excellent service to our electorate. Like other municipalities across the country, Mangaung is faced with the challenges of service delivery backlog in areas such as housing, water, sanitation and unemployment. We have identified several interventions, like identifying pockets of land in Vistapark, Ceciliapark, at the airport and Hillside View to accommodate the rising demand for housing. The city is also losing a lot of revenue through water pipe leaks. However, the minister of Water Affairs has committed to assisting the municipality in financing programmes to help reduce the problem and ensure an end to the underground pipe leaks that are making the city lose millions in revenue. As with any major city in the world, Mangaung is also privy... Read More

R59 million upgrade of R72 under way

In May 2012, the ownership of the R72 in the Eastern Cape was transferred from the provincial government to the South African National Roads Agency Limited (Sanral). With an appropriate budget for routine road maintenance and a contract structure that provides for the development of SMME contractors, the R72 will be rehabilitated to be a road of national standards. Not only will the R72 benefit from structured routine road maintenance programmes but also through planned upgrades of sections of the road in future. The project comprises the routine road maintenance on national route R72 Sections 1 to 4, between Nanaga and East London Airport off-ramp, spanning a total distance of 228.5 km. The scope of works involves the routine road maintenance, improvement of drainage structures and minor works along the route, which include: general requirements and provisions contractor’s establishment of site obligations route patrol services accommodation of traffic pavement layers repair repair of potholes, edge breaks and surface failures crack...

N6 between East London and Stutterheim upgrade

A contract awarded by the South African National Roads Agency Limited (Sanral) has resulted in a significant portion of the N6 receiving an extensive upgrade. The leading consulting engineering firm GIBB undertook the design and construction management for the resurfacing of the road in a project that cost over R55 million and created 87 jobs for locals. The contract is located on the N6 between East London and Stutterheim. The new road surface is expected toextend the lifespan of the surfacing by eight to ten years with enhanced safety characteristics due to improved skid resistance properties. The new sidewalks also offer safety benefits to pedestrians, who no longer have to walk on road verges. While this portion of the N6 was still structurally adequate (except for isolated areas where base repairs were necessary), the surfacing seal was aged and oxidised. Simon Tetley, senior associate at GIBB and the project leader on this contract,says that to prevent further degradation, a new... Read More

Advanced processes applied

Constructed as part of the larger Roodeplaat Bulk Water Supply Project, the Roodeplaat Water Treatment Works is now one of the most advanced water treatment facilities in terms of process configuration in South Africa, Bigen Africa project manager, Ian Pollard, tells Chantelle van Schalkwyk. This can be attributed to the fact that the City of Tshwane deciding to implement the advanced processes of ozonation and granular activated carbon (GAC) filtration processes proactively, in anticipation of expected future deterioration in raw water quality. “The use of ozone in municipal water treatment is certainly not a new process, but it is not deemed conventional in South Africa. The Roodeplaat plant is currently one of the most advanced plants in terms of process configuration in the country and probably in Africa,” explains Pollard. The 60 Mℓ/d Roodeplaat Water Treatment Works (WTW)was commissioned in 2005 as part of the larger Roodeplaat Bulk Water Supply Project to augment water supply to the rapidly expanding northern...
