Restrictions in relation to time, space, weather conditions and working conditions were all overcome to provide a world-class tourist facility The Table Mountain cableway, opened originally on 4 October 1929, is one of South Africa's premier tourist attractions. Eleven million people visited Table Mountain between 1929 and 1996, experiencing the thrill of riding the cableway and enjoying the magnificent views from the summit. By 1992, the cableway could no longer meet peak passenger demand, resulting in waiting times of up to six hours and, on occasion, the closure of Tafelberg Road. The cableway was closed temporarily from January to September 1997 to allow major alterations and upgrading of the facilities.
The Mantsole Traffic Control Centre north of Pretoria addresses a vital need in terms of traffic safety and road degradation related to overloaded freight trucks, with associated savings in costs and human life The first and pilot traffic control centre in a proposed national network of such facilities was officially opened by the Minister of Transport, Mr Mac Maharaj, at Mantsole in May 1997. The complex is situated 70 km north of Pretoria on the N1. South Africa's road network is steadily deteriorating in the face of severe funding constraints. This is further aggravated by the simultaneous deregulation of transportation, resulting in a shift from rail to road freight, and a steady increase in the overloading of heavy vehicles.
As revellers ring in the new millennium on 1 January 2000, some computers will be scrambling data or grinding to a halt. Here's how one engineering company is preparing to outsmart its computer systems before disaster strikes. What would happen to your organisation if any of the following were to occur: You specified a flowmeter that malfunctioned and your client sued you for lost data? You couldn't pay your employees? Your clients couldn't pay you? Your bank cut off your line of credit because you were considered a risk?
This paper descriptionbes some of the work of the engineering department of the Imperial Military Railways during the first few months after the occupation of the Transvaal by British troops, chiefly that of the repair and maintenance of the line east of Pretoria, a considerable portion of which was carried out under the supervision of George Bransby Williams, the author. (For Part 1, see February 1999 issue.) Maintenance of the line The permanent-way on the Pretoria Eastern Line is, judging by South African standards, good. As on all other railways in that country, the gauge is 3 feet 6 inches. The rails are laid partly on teak, and partly on iron sleepers.
SRK Consulting (SRK) was recently judged one of the five most global companies in South Africa in an index developed by Business Report, Barlows and Price-(No Suggestions). The winner of the award was Boart Longyear and other runners-up included Sappi, Barlows and the Forbes Group. The objective of the competition was to measure South African companies' ability to compete on a global stage. The judging criteria included foreign assets and sales, brand spread, employees overseas, management with International experience and environmental and social responsibility codes. The competition was open to both listed and non-listed companies, large and small, whose ultimate control and management is domiciled in South Africa.
When we built the Okiep-Springbok road in 1950 we had trouble with the reprehensible urge young speedsters felt to ride on the basecourse when it had been so-nicely mixed, spread, graded, rolled and trimmed, all ready for surfacing. This joy-riding left very obvious tracks in the wet surface, which showed through the sand surface seal we were using there.
The paper descriptionbed a comparative study made of the engineering properties of four soils stabilized with binders consisting of various proportions of Portland cement and milled blast furnace slag, and slaked lime and slag.
The paper dealt with the origin of network diagrams and gave a brief descriptionption of the technique. A simple example of a network diagram was worked out in detail to show the stages necessary to construct a diagram for a large construction or maintenance job. The advantages of network diagrams compared to bar charts were explained and the extent of their use indicated.
