Some 18 months down the line, the rehabilitation of the Bospoort Dam for client DWA (Department of Water Affairs) is complete. The Bospoort Dam is located on the Hex River in the North West Province, approximately 15 km to the north-east of the Rustenburg Dam. It is dedicated to the supply of primary water to the municipality of Rustenburg. The dam has been rehabilitated in line with safety requirements as part of the DWA's Dam Safety Rehabilitation Programme.
Division chairman appointed to the IStructE Council
In the previous report we informed members that the division chairmen were to be included in the IStructE Council. Hence I attended three Council meetings in London. There is absolutely no doubt that this concept has improved communication and cooperation between London and the JSD.
The world-recognised standard for mining structures, SANS 10208, was put under the spotlight at a special seminar which was the forerunner to the Southern African Institute of Steel Construction's (SAISC) conference on 'Structures for Mining and Related Materials Handling'. The conference, the first of its kind in the world, was held at Sun City, South Africa, from 9 - 12 November 2009.
The Mgeni Viaduct in Durban bridges the Mgeni River to link residential and industrial zones in the greater Durban area, as well as providing a link road to the new King Shaka Airport. The project started in July 2007 and is due to be completed in March 2010, with a project value of R187 million.
In 2008 the agency came up with the idea of constructing large soccer balls on some of the Telkom towers as an advertisement for Telkom. These balls were to be the largest ever used to advertise a soccer world cup event. The Agency then approached Graphic Wizard with the idea, who in turn contacted Signsmith cc regarding the project.
It is the aim of this article to provide forthe non-geophysicist an up-to-date introduction to the usefulness of land seismic surveys in civil engineering. Applications of the seismic refraction method in depth-to-bedrock studies, excavation problems and geotechnical work are discussed and indications of the limitations are given. Emphasis is on the use of the results rather than on their collection and so, except where relevant, no mention is made of the principles and field practice of seismic surveys.
Repeatedly at MBB Consulting Engieers we see the expensive and often chaotic results of farmers and developers not obtaining specialised engineering input when installing largescale irrigation or bulk water supply systems. In fact, any system that presents challenges or is outside normal parameters requires engineering expertise to ensure that problems are dealt with effectively and that the system meets delivery requirements. The following case study illustrates this point.
The paper reviewed the work carried out by the NIRR on the monitoring of highway pavement temperatures throughout Southern Africa. Fundamental aims of the paper were to make the practising engineer aware of the range of temperatures to which local pavements are subjected and to provide him with a convenient means of reference to temperature data for the design of future road pavements.
The main aim of a safety audit is to ensure that all new road schemes operate as safely as is practicable. This means that safety should be considered at every step during the preparation and construction of any road project.
Two formal papers, one published in the UK and the other in South Africa, have appeared in their respective professional journals, both written by full-time researchers, but canvassing somewhat different aspects of the research environment. They both comment also on the private sector's potential role in the research process, and in particular the sector's role in introducing research findings into practice.
