The South African National Department of Higher Education and Training (DHET) announced that engineering skills dominate the top 20 most sought after scarce skills - civil engineering features second on the demand list behind electrical engineering. Th is view is endorsed by the Department of Labour (DoL). In South Africa, a scarce skill is a qualification or job for which there are limited people doing that job. Effective utilisation of scarce skills has been proven to set countries on a winning economic pathway, as evidenced in Singapore, China, Japan and many others.
Talking to the hearts of visiting high school learners in the audience at the opening of the recent Africa Engineering Week, Minister Pandor inspired not only learners to appreciate the importance of engineering for our country, but seasoned engineers in the audience also took heart listening to a Minister who clearly has an understanding of their profession.

In 2012 the first author asked whether it was the right time to implement Gauteng's open road e-tolling system. He came to the conclusion that it possibly was not, based on the notion that a number of prerequisites had to be met first. Now in 2014 we ask some different questions. Firstly, what amends have been made in dealing with the requirements, and secondly, what will happen if the GFIP e-toll project is discontinued? Yes, if the project is canned?
The City of Johannesburg is one of the largest metropolises in Africa, with more than 2 000 intersections controlled by traffic signals. The Johannesburg Roads Agency (JRA) is responsible for the operation and maintenance of traffic signals on roads that are the property of the City of Johannesburg. When power interruptions occur, the traffic signals are regarded as four-way stops, and the delays at these intersections are then much higher than under normally operating circumstances. The possibility of accidents is also higher and of great concern to the JRA, as acquainted road users might perceive the progression of vehicles ahead as moving due to a 'green' signal, and this has the possibility of rear-end shunts.
The resilient behaviour of an unsaturated, unbound granular material is a primary input used in the mechanistic analysis of pavements incorporating such layers. Various models exist for the determination of the resilient behaviour, mainly based on the output of tri-axial laboratory testing. In a paper published in the Slovak Journal of Civil Engineering (Van Aswegen & Steyn 2013) an investigation is presented where basic engineering properties, such as grading, laboratory compaction characteristics and optimum moisture content, are incorporated into the resilient behaviour model to quantify the effect of basic material properties on the resilient response of unsaturated, unbound granular materials. Such a resilient behaviour model will enable practitioners to estimate the behaviour of specific material, which might enable the use of available quality material that was discarded in the past.
The citizens in the residential area of Ocean View in Cape Town are in urgent need of improvements to their road infrastructure. This can be done by providing sustainable solutions to current challenges, which will improve the living conditions of citizens in the long term, as well as create a safer environment.
Arup, with ROM (Israel), is undertaking a World Bank funded project (for the Ministry of Works and Transport in Uganda) to develop a detailed design of a pilot Bus Rapid Transit (BRT) system in Kampala, the capital city of Uganda. The BRT in Kampala will be operated with articulated buses on exclusive on-street bus lanes. This article outlines an approach in which the design of each system component responds to the operational concepts and design philosophy, recognising that each component has a significant impact on the business case and the financial sustainability of the system.
Southern African Development Community (SADC) member countries can no longer afford to isolate themselves from the muscle that the SADC is. They do so at their own peril. If SADC is indeed a muscle, transport is the core muscle fibre, without which the region cannot move. This article discusses ways in which transport can be an enabler for sustainable development through the implementation of the 1996 Protocol on Transport, Telecommunications and Meteorology.
It is no secret that road maintenance is vital to provide safe, reliable transport for the advancement of the South African economy. The Bakwena Platinum Corridor Concessionaire (Pty) Ltd is committed to managing, maintaining and upgrading its road infrastructure (N1N4 Platinum Highway) to international standards. Since signing a long-term concession contract with SANRAL (South African National Roads Agency Limited) more than 12 years ago, Bakwena has successfully managed a 90 km stretch of the N1 from Tshwane northwards to Bela-Bela (Warmbaths), and a 290 km stretch of the N4 running from Tshwane westwards to the Botswana border post at Skilpadshek. Funding for this maintenance is derived exclusively from tolling.
The aerotropolis has become the new port of the 21st century, and it is a major driver of urban form and economic activity. It provides an opportunity for inland cities to develop and to compete in the global economy. Airports around the world are transforming themselves into aerotropoli.
Saice's Transportation Engineering Division held their annual Chairman's Award Luncheon on Thursday 29 May 2014 at the Accolades Boutique Hotel in Midrand. The event saw more than 120 engineers from many leading transportation engineering companies attending, as well as guest speaker Hishaam Emeran from the Passenger Rail Agency of South Africa (PRASA).
Chapter 3 of this series (Civil Engineering, April 2014, p 41) described the building, up to the start of the Second World War, of a foundation for a country-wide transportation network. In this eighth chapter, the development of a national arterial road system from the mid-20th century up to its end will be described. Th is development of a good road system following the "get out of the mud" rudimentary network of earlier years was necessary because of the increasing role road traffic was beginning to play in the economic and social life of the country.
This is the second in a series of articles on Dispute Boards (DBs) and is Part 1 on the operation of DBs. It describes the operation of a DB, dealing with the appointment of DB members, composition of a DB, remuneration and termination. Site visits, informal advice and opinions, formal referral of disputes, hearings, DB decisions and the avoidance role of DBs will be dealt with in future articles. The first introductory article in this series, appeared in the August 2014 edition of Civil Engineering.
Mammoth culverts, manufactured by Aveng Manufacturing Infraset, have been used for the rehabilitation of a corrugated metal pipe which collapsed under André Greyvenstein Road near Gauteng's OR Tambo International Airport in November last year.
B-BBEE is a controversial subject. Some see it as a necessary process in the normalisation of our country, while others believe it is a blunt tool which until now has benefited only a fortunate few. Very few people are neutral on the subject. In a refreshing example, Cargo Carriers and Lafarge have concluded a deal which supports the real spirit of the concept. And innovative thinking is at the heart of the solution. In a logistics industry where optimisation, and high levels of SHEQ and critical mass are often required to manage productivity up, and costs and risk down, these two organisations have found a way to create a safe and value-creating gap without sacrificing the aforementioned holy grails.
Engineering professionals tend to be labelled as poor communicators. The American Society of Civil Engineers (ASCE) has, for example, deemed it important enough to list communication as one of the 24 Professional Outcomes, or Prerequisites for the Engineer of 2025. ASCE considers it as one of the 'hard' skills for engineers to master, in contrast to technical skills such as mathematics, which is now labelled a soft skill - for some at least.
Emeritus Professor Vincent Louis Granger, the first permanent Dean of the Faculty of Engineering at the University of Cape Town (UCT), passed away in Somerset West at the end of 2013 at the remarkable age of 96.
