In Africa, as in the rest of the world, the collective voice has a greater impact than the most fervent solitary opinion. SAICE offers exactly that vehicle for the civil engineering community. As a representative for the group, SAICE is able to say with authority and influence what the individual civil engineer is unable to say.
On 8 February a visibly happy but modest Seetella Makhetha was inaugurated as SAICE's president for 2011, amidst warm support from SAICE members, family and friends, and staff who flew in from Port Elizabeth for the occasion.
It is indeed an honour and privilege to deliver this presidential address and to accept the duties and obligations of President of SAICE for 2011. It is a duty to which I do not come unprepared. Past-President Ali Naidu has prepared and coached me well, and for that I am grateful. The staff of SAICE and especially our young and new Chief Executive, Manglin Pillay, have badgered me over the past several months regarding tonight's event. I am delighted that the preparation and planning are working so well.
Recent communication dealt with the concept of a question and answer database which could be housed on the website, and to which members could turn for answers to commonly asked questions around the subject of structural engineering. Whilst experienced engineers may not need such a service I believe that the question and answer method might provide a very valuable tool through which up and coming young engineers could broaden their experience with very little cost or effort. It will take time and effort, though, to create, develop and expand such a question and answer database. This is a project that my committee will be looking to implement during 2011.
At the risk of these articles starting to sound like a cracked record, the Southern African Institute of Steel Construction's 2010 Steel Awards, with Grinaker-LTA as main sponsor, once again resulted in a year of records.
The King Shaka International Airport and the Dube Trade Port, located some 35 km north of the Durban City Centre, is a strategic and critical infrastructure development which will serve as a catalyst for economic growth in the KwaZulu-Natal region and South Africa.
A number of factors related to the urban transportation problem in Cape Town are outlined and the main trends are illustrated. The conventional urban transportation planning process is briefly introduced and the importance of the trip generation sub-model of the traffic forecasting process is highlighted.
The Warwick Triangle precinct is the busiest transport hub in Durban. The major access to the CBD from the west passes through the precinct and the precinct is the location for the main rail terminal, as well as bus and taxi ranks. To mitigate against the conflicting traffic movements it was necessary to separate, as far as possible, traffic within the precinct and traffic that was passing through. The best way to achieve this was to build a viaduct that would carry outbound traffic over the existing Eilat Viaducts, Market Road and Warwick Avenue before merging with the Western Freeway.
Many structural designers seem to start the design process with a major assumption - that the materials to be used in the eventual construction will behave in a manner prescribed in a code of practice. With a prefabricated material as predictable as steel, this is a reasonable assumption; concrete is, however, a very different proposition, whether it is bought ready-mixed or mixed on site.
The South African steel design code is based on the Canadian S16 steel design code. The five-year review of that document has commenced. There are numerous research activities going on at South African universities about the possibility of replacing the S16-based code with a Eurocode-based document.
The main intension of hot dip galvanising, or painting exposed steelwork for a building, is to prevent the steel from rusting, ideally lasting for the service life of the building. (Performance of the two systems is not up for debate in this article.) The method of application of the two systems is vastly different.
