Despite being in my mid-thirties, I still dread visiting the dentist where, on a recent visit, I noticed that the other teeth and gum conscious citizens, together with the receptionist, liberally referred to the dentist as 'doctor', sometimes in the presence of the dentist herself. Is a dentist a doctor in the traditional sense? And was it alright to ask this question to the dentist without being insensitive and offensive? I did ask the question and her instruments squealed and spun a bit more than usually that day. So in engineering, who does what, at what level and in what context?
The Trekkopje Maxi Project Front End Civil Works, for AREVA Processing Namibia (Pty) Ltd, has been under way since August 2010, and is being undertaken by Stefanutti Stocks in joint venture with Namibia Construction. The contract entails the construction of civil structures comprising 12km of concrete rail beams, a crushing and screening plant, an agglomeration plant, two silos, large in situ culverts, conveyor lines, miscellaneous civil works and associated industrial building works.
Roads are an important element of the public infrastructure with a significant capital value. There has been much public debate recently regarding the most appropriate manner to finance the provision and maintenance of public infrastructure with particular reference to roads in metropolitan areas, such as Gauteng.
In civil engineering the concept of 'art' is typically understood as the aesthetic elements created by the designer, as embellishment of architecture for example, or certain visual effects on a bridge design. The prospect of civil engineering being an art form remains outlandish and not something easily accepted by the scientific society.
Just under 5000m of precast concrete stormwater piping is what it will take to drain Waterfall City, currently under construction and earmarked to become Midrand's new central business district. The concrete pipes were specified by the Johannesburg Roads Agency (JRA) for what is seen as one of Gauteng's largest infrastructure projects to date.
Risk is an inherent part of any business. However, risks can also be viewed as externalities in the right conditions, such as natural hazards that wreak havoc. The fact of the matter is that risk cannot be viewed in a 'silo' form. The 'silo effect' typically applies to the more historical forms of assessing risk. Examples include disaster risk, financial risk, operational risk, fire risk and the list goes on. This article therefore aims to illustrate the multi-scalar and multi-dimensional nature (complexity) of risks, with a special focus on the interconnectedness of operational and disaster risk.
In South Africa, the problems of unemployment (approximately 40% unemployed according to the broad definition and over 25% using the narrow definition) and poverty alleviation are of national strategic importance. The government of South Africa has made a nationally significant response to this problem through the largest development programme in the country's recent history. The Expanded Public Works Programme (EPWP) is a visionary component of the South African government's multi-pronged strategies towards poverty alleviation, job creation and skills development.
Claims are a part of everyday life in engineering, building and construction industry contracts. There is often a tendency, however, for a claim to be formulated on a "global" basis, as opposed to being built up from individual events showing cause and effect in each case. Hence, a global claim, as between the employer and the contractor, is often a contentious issue. Such claims do not find favour in South African courts. This situation may be changing at least in the United Kingdom, where English law is often referred to by South African legal practitioners for an up to date stance on engineering and construction law. This article examines the outcomes of recent English cases which may indicate a softening of English courts' attitude towards global claims.
Infrastructure comprises fixed assets that are constructed or result from construction operations including:
buildings, structures and facilities
water supply, sanitation, electricity supply, transportation and stormwater drainage systems
the related permanent fixtures that cannot be readily or economically removed or reused.
Sections 38 and 51 of the Public Finance Management Act 2000 (PFMA) require accounting officers and accounting authorities respectively to ensure that their institutions have and maintain a number of systems relating to risk and financial management, internal control, internal audit, procurement, provisioning and the evaluation of major capital projects. The PFMA Supply Chain Management regulations also prescribe that institutions implement a supply chain management system.
The cost and time saving advantages of using precast hollow core concrete slabs in particular applications are being well demonstrated in the construction of Stellar Wholesale City a multi-tenant wholesale facility in the Crown Mines area of southern Johannesburg.
During the years of cement-demand high growth rates in the late 1990s and early 2000s, the South African cement industry had little incentive to formulate specialist products for the road construction sector. With the commissioning in 2009 of its state-of-the-art grinding station at Randfontein, Lafarge Cement wholly owned subsidiary of Lafarge had the available capacity to introduce innovative new products and develop new market sectors.
This skills-development paving manual, produced by the Concrete Manufacturers Association (CMA), is aimed mainly at the unemployed township dweller who, by using the manual, can develop a useful income-producing skill.
When we think of concrete, most of us think of it as being dull, grey and boring. Architects and engineers normally choose to use concrete as construction material because it is deemed to be durable and cost efficient.
Launched 30 May this year, this attractively presented and informative book is the result of four years of research by the author, Lani van Vuuren, who is also the "Public Understanding of Science Officer" at the Water Research Commission and the editor of Water Wheel. As Lani states in the author's note, South Africa's history of dams goes back at least four centuries, and "behind each dam lies a tale of imaginative thinking, daring spirit, and resolve to make South Africa a better place to live in." The book "takes the reader on a journey through the history of South Africa's large dams, starting with the traditional attitudes towards water resources prior to European settlement and ending with a glimpse into the future of dam building in the country.

The SAICE YMP (Young Members Panel) is a voluntary unit of SAICE and was established to facilitate the development of young engineers in their learning curve to becoming competent engineering personnel in our industry.
The Young Contractors Forum (YCF) was established to invest in the continuing professional development of the youth in the construction industry, i.e. people 35 years or younger with a tertiary qualification, working for SAFCEC affiliated companies in South Africa and abroad (South African Federation of Civil Engineering Contractors).
"Practical, fun, challenging, energising, interactive, inspirational" a few of the words delegates typically use to describe the Leadership and Management Principles and Practice in Engineering course when checking out after two very busy days.
