The foundations for the arch over the Moses Mabhida Stadium in Durban are unique in concept, design and construction, and were completed and successfully load-tested entirely by local engineers and contractors under intense international technical scrutiny and public interest. The timeous completion of this aesthetically limited but crucial component was pivotal in keeping the stadium project on schedule.
The Gansbaai project is the world's first full-scale domestic demonstration sewage treatment works implementing Nereda® technology, a major breakthrough in secondary treatment that forms granules instead of flocs in the reactor. Substantial savings in space requirements, as well as in capital and operating costs have been achieved.
In 2005 GIBB was appointed as the main consultant to investigate the immediate and long-term disposal of sewage within the Helderberg area by the City of Cape Town. At the same time, GIBB was investigating options for Heartland Properties which owns about 700 ha of undeveloped land in the Helderberg Basin.
The design and construction of the new dense waste water marine outfall pipeline and pump station for Richards Bay is an excellent example of a successful combination of design ingenuity, sheer project size and demanding and challenging construction techniques and conditions.
The R292 million design and construction of the first phase of the Northern Waste Water Treatment Works Unit 5 presented unique aspects that required an unusual degree of engineering ingenuity and innovation to merge the technical aspects of the project with acceptable construction and environmental solutions. Extremely tight programme deadlines were met through concerted and dedicated efforts by an integrated, multi-disciplinary design team, thereby contributing hugely to the socio-economic development of the Diepsloot area and of the Gauteng Province.
In December 2004 BKS (Pty) Ltd and BVI Consulting Engineers were appointed jointly by the Department of Public Works and Roads of the Free State Province for the design and construction of a new bridge over the Caledon River near the town of Wepener.
The Kaaimans Pass between George and Wilderness is one of the most picturesque areas along the Garden Route, which draws many tourists to the area. It is unfortunately also increasingly important for the movement of road freight along this National Route between George and Port Elizabeth. The section of Kaaimans Pass, specifically between the Swart River (km 32,300) and Kaaimans River bridges (km 33,200) includes the infamous horizontal curve at km 32,700 which became known as 'Death Bend'. Frequent accidents involving local inhabitants, foreign tourists and commercial freight vehicles created a media outcry.
The upgrading of the Western Freeway in Durban has provided the eThekwini Municipality with an asset which has been highly responsive to community needs. The project involved established and development level contractors, and included a high degree of municipal engineer involvement in fiscal budget and phasing requirements, as well as innovative structural and roadway features and asphalt design. It is the first dedicated public transport lane in KwaZulu-Natal, with significant aesthetic and safety improvements, and minimal environmental impact.
This project is a prime example of the successful cumulative result of vision from the client, architectural creativity, analytical capabilities of the engineer and a highly skilled contractor. In addition, this process of gentrification might just start a ripple effect of upgrading and renewing one of the older industrial zones in East London.
Every once in a while stakeholders in a project mesh to produce something special, something innovative that changes the way similar projects will be engineered and managed from then on. One such project was the introduction of the first Ultra-thin Reinforced Concrete Pavement in South Africa by the Gauteng Department of Public Transport, Roads and Works
The iSimangaliso Wetland Park Authority has embarked on an infrastructure development programme aimed at creating the much-needed infrastructure required to support a fast-growing tourism industry. This programme extends over a number of financial years and is mostly funded through the Expanded Public Works Programme.
The Vuk'Uphile learnership project of the Department of Public Works, under its Expanded Public Works Programme, offered PD Naidoo & Associates (PDNA) the opportunity to address the lack of training and skills development in coastal areas and realise the adage of "give a man a fish and you feed him for a day, but teach a man how to fish and he'll eat for a lifetime". Key to the project was attracting skills from previously disadvantaged communities, and involving skilled practitioners to transfer technical, management, administration and financial skills with the objective to mentor and train learners into becoming independent, skilled contractors.
Rio Tinto recently commissioned its Mandena mine, situated about 10 km north of the small town of Tolagnaro in southern Madagascar. The mine extracts titanium dioxide from mineral sands using the water-intensive dredge-mining process. This requires up to 20 Mℓ of water per day.
The R200 million Ntimbale Dam Project was implemented by the Government of Botswana to significantly improve water supply and the quality of life for the 10,000 inhabitants in 52 villages of the North East District and part of the neighbouring Central District. The project has been designed to cater for an expected seasonal peak domestic demand of 11,825 Mℓ / day by 2017.
Dubai's population is expanding steadily with a corresponding rapid growth in urbanisation and increasing traffic congestion. To address the traffic situation, the then Dubai Municipality Roads Department (now the Roads and Transport Authority) initiated planning for an upgraded, integrated transport network, which included, in March 2005, Project R880 for the development of the Mirdif Interchange.
The core element of Project R880 was the replacement of an existing road bridge at the Mirdif Interchange (which is the intersection of Al Khawaneej and Algiers Roads) with a high-capacity flyover. This intersection services the residential areas of Mirdif, Al Muhaisnah and Al Mezhar.
