We need a rational approach to green buildings. We need to invest in sustainability. We need to asses total costs, also costs to the environment. It is no use having a house that runs on computers and fancy climate controls made in Singapore or Taiwan if the computers are costing us more in terms of environmental impact than simpler methods.
it is generally accepted that at some time in the comparatively near future - say between 2025 and 2055 - it will be necessary to supplement the water supplies of the Republic of South Africa, as well as those of some other water-scarce countries in the SADC region. As it would typically take 30 to 40 years to bring a major international water transfer scheme to fruition, it is not too early to start looking at various possibilities. The authors suggest that the rivers of Central Africa could possibly serve as one of the future sources for water supplies for the dryer south. If a scheme to transfer water from the water-rich rivers of Central Africa southwards to Botswana, Namibia, Zambia, Angola, Zimbabwe and South Africa were to be tackled on a sufficiently large scale, considerable royalties could be generated for the benefit of the northern-lying countries.
BKS needed to address various practical and technical issues and apply some innovative thinking when designing the lining system that was to piggyback on to the existing wastefill area at the infamous Coastal Park landfill (G:L:B+) site.
The country is facing an enormous backlog in access to adequate sanitation by all citizens and the target of eliminating this backlog by 2000 seems to be unattainable at the current rate of delivery especially in rural areas. Attempts are being made to accelerate delivery while ensuring that the projects add value to the community in terms of improved skills and improved potential to access jobs and alleviate poverty. The community-based delivery of sanitation offers the best potential for accelerating delivery and ensuring development of skills and maximum income for the community. In many cases, however, inappropriate planning and design well as incorrect management of community-based projects has led to a general misconception that community-based delivery is slow and risky and cannot contribute to the accelerated delivery of sanitation. The Phelandaba sanitation project implemented by the Mkhanyekude District Municipality is a good example of how community-based delivery can be both effective and efficient and can help alleviate the sanitation backlog while contributing to job creation.
Standing on one of the hundreds of collapsed smallholder irrigation schemes in the former homelands, one has a tangible sense of unused opportunity which is starkly amplified by the surrounding poverty, unemployment and social need. It is easy to understand why inspired politicians imagine a sea of green and commit hundreds of millions of funding annually to rebuild infrastructure, in the hope that this will result in profitable production.
Building a state-of-the-art particle board plant as part of a greenfield development in the remote rural town of Ugie with little by way of supporting infrastructure or services presented PG Bison's project engineers and contractors with unique opportunities and challenges.
The N6-Reddersburg rehabilitation project which was awarded in a joint venture by the South African National Roads Agency Limited (Sanral) began its construction phase in January 2006.
The N6 road forms part of the national road network of South Africa and carries regional and national traffic. It is also the main link between the industrial areas of Gauteng, the mines in the central Free State and the port city of East London on the southern coast of South Africa.
The World Bank estimates that countries of the Middle East and North Africa already consume 20% more water than they receive through rain and river flows, leading to depletion of groundwater supplies. This could get worse with climate change and, according to the United Nations Development Programme (UNDP), 40% of the world's population will suffer water shortages by 2050.
Grinaker-LTA Civil Engineering, in joint venture with Murray & Roberts Civils, is providing substantial civil works for the new Khumani iron ore mine which is being developed by Assmang Limited on the Bruce, King and Mokaning farms in the Northern Cape between Kathu and Olifantshoek.
South African civil engineers operate in a unique environment. Multi-disciplinary projects have placed greater emphasis on infrastructure design software where integration across services is key. The recent infrastructural boom in South Africa has seen many infrastructural design programs evolve to offer sustainable solutions.
Rural construction projects, which are usually small in monetary terms, can impact greatly on the lives of remote communities. Two such projects have been completed recently, one in the province of KwaZulu-Natal, and the latest one reported here, in the Eastern Cape.
