Austrian-based Tiroler Rohre GmbH (TRM), who offers numerous top-quality products made from ductile cast iron, is the developer and manufacturer of the TRM piling system which, over the past 30 years, has earned a well-established track record for deep foundation engineering applications and solutions throughout the world. Typical project types include buildings, railways, bridges, storage tanks, silos and many structures in the mining and energy sectors.
Marelize is the chairperson of SAICE’s largest division, the Joint Structural Division (JSD), which currently has 2 100 members. The JSD comprises members from both the South African Institution of Civil Engineering (SAICE) and the UK-based Institution of Structural Engineers (IStructE). In 1937 the South African branch became the first to be established outside the United Kingdom, and this year the JSD will be celebrating its 80th anniversary. Debbie Besseling chats to Marelize about the JSD and her career as a structural engineer.
ECSA (Engineering Council of South Africa) registration is a generic process, based on education, training and experience at an entry level to a profession. Registration as such confirms that a person is capable of working independently. ECSA thereafter relies on the integrity of a registered person (selfregulation) to not take on work which he is not competent to perform, and to perform work within the “norms of the profession”. The shortcoming with this approach is that no matter how ethical a registered person may be, he is not capable of self-assessing what he does not know. Alternatively, a registered person may solve the wrong problem.
Timber has always been the stepchild of the construction industry, with tertiary institutions concentrating on materials such as concrete, steel and even masonry. To understand what has happened in the timber truss industry and its growth one has to go back to the days of hand calculations, such as node equilibrium and method of sections that were used to analyse trusses. Loads were concentrated at the nodes, and members analysed for axial forces only. Tables or moment distribution were used to determine the bending moments in top and bottom chord. Connection design was difficult, as eccentricities had to be taken into account. The whole process was laborious and time-consuming, with only the bravest of engineers attempting hipped roofs and girder trusses. Skilled carpenters who had been trained in Europe were employed to build and erect the difficult roofs. Bracing of the roofs was not an issue, as in many cases the roofs were sheeted and the sheeting supplied the necessary bracing. Slate roofs had battens at close spacing and the slate had to be nailed down. The nailing of the slate ensured that the slate formed a bracing membrane, as did concrete tiles that were nailed down.
Motorists travelling on the busy N1 through Midrand every day, and commuters on their way to and from their offices in the Vorna Valley, Waterfall City and Kyalami precincts have over the last year or so been fascinated by the growing tower adjacent to the Mall of Africa. Here is the story of this impressive and intriguing new landmark.
The 35th Steel Awards event, hosted by the Southern African Institute of Steel Construction (SAISC) in partnership with BSi Steel as main sponsor, was held towards the end of last year. These prestigious annual awards recognise excellence in the use of structural steel, and the 2016 entries again proved that, despite the current enormous challenges in the steel construction industry, South African engineers and architects continue to produce world-class work. In this article we present the winners to our readers.
The associated design, performance, durability and maintenance of marine concrete structures is a rapidly evolving and critical area of interest to engineers, technologists, technicians and other related professionals.
The consulting engineering industry comprises a collection of professional engineers, architects and scientists who are lending integrated services and valueadding solutions to technical problems for their clients. Depending on the type and size of a client’s project, the roles of professionals within consulting firms may range from purely technical, to coordinating or managerial, or a combination thereof. It is therefore essential for such businesses to have groups of people who can sell their skills and demonstrate the capabilities of delivering on time, within budget and to agreed client expectations. These are vital ingredients for winning client work, as well as confidence. To ensure effective control of project schedules and financials, growing consulting engineering firms are motivated to choose dual-management functioning, i.e. technical and project management. In light of various dual-functioning impacts, it has become important to explore a common platform where the skills of the technical leader and project manager complement each other.
On the following pages readers can learn more about the five exceptional engineering practitioners who were the winners in the Individual Awards sub-category at SAICE’s 2016 awards function in October last year.
