When a boisterous Bernie Krone manoeuvred a dump truck around Frankipile in the early seventies, the thought that some 30 years later the high-spirited youngster would acquire that concern and merge it with construction company Esor might have seemed like a fantasy. Today that youthful zest and confidence are still there in abundance, with foresight, business acumen and gritty resolve mixed into the equation. While talking to Bernie after he had received the Gold Medal of SAICE's Geotechnical Division, Lorraine Fourie heard the phrase, 'ninety per cent of success in life is being in the right spot at the right time', cropping up several times
Geotechnical engineers use the results of soil tests when assessing the likely behaviour of foundations and other geotechnical structures and assume professional responsibility for these assessments. But how reliable are the results they receive from the soils laboratories? This article compares the results of basic soils tests on two samples sent to four commercial soils laboratories in the Gauteng area in late 2006. The variation in the values obtained was sufficiently wide to lead to an incorrect assessment of soil behaviour. A follow-up trial was carried out at the beginning of 2008. No improvement in the consistency of results was noted. Possible ways of addressing this problem are explored
Being involved with the design and construction of the Soccer City Stadium would seem at first to be like most large-scale construction projects. It is only as the excitement and anticipation builds approaching the 2010 FIFA World Cup that the realisation dawns as to the great privilege it is being part of this amazing project
An Arch Three-Quarters of the length and height of the main span of the iconic Sydney Harbour Bridge will be the most visible feature of Durban's new Moses Mabhida stadium. At time of writing, the foundations had been constructed and erection of the arch was imminent.
Construction has recently started on the new N17 freeway link in Soweto, with site establishment and enabling works under way. The 5,8 km freeway link will provide much needed access from the N1 to Soweto and the Soccer City and Orlando stadiums.
In Centurion, South Of Pretoria, the Gautrain Rapid Rail Link will cross the residual dolomites of the Monte Christo, Lyttelton and Eccles formations on a series of viaducts supported on piers spaced generally at between 44 m and 56 m apart. The construction of the link has been entrusted by the Gauteng Provincial Government to a joint venture comprising Bouygues Public Works, Murray & Roberts and SPG. Africon has been commissioned as designer for the Viaduct section by the Civil Works Joint Venture.
After a relatively quiet period, southern Africa is now in the thick of a period of intense tunnelling activity. This has been the consequence of the urgent need for more power at peak periods, the start of a major railway project, and the ever-increasing need for water in Gauteng. While this state of affairs is to be welcomed, the country's construction resources are being severely stretched to meet these needs.
The Mkomaas river pedestrian bridge that was recently constructed in the Mkomaas Valley, in a remote part of KwaZulu-Natal, is the first prestressed ribbon bridge in Africa. The clear span of 150 m equals the world record for this type of bridge.
Civil and geotechnical engineering contractor Esor is prominent in the Sandton CBD with the construction of lateral support for some key projects, one of which is located only 20 m from the Gautrain station
The Geotechnical Division of the South African Institution of Civil Engineering (SAICE) is a technical subcommittee for professionals active in geotechnical engineering. The division has a committee consisting of volunteers that represent and promote the interest of its members. The division is affiliated to the ISSMGE (International Society of Soil Mechanics and Geotechnical Engineering) and currently has some 280 members.
The Geotechnical Division of SAICE hosts a Young Geotechnical Engineering Conference (YGEC) about every three years. The conference aims to attract young geotechnical and environmental engineers, as well as engineering geologists and geologists.
GeoCompaction Dynamics is a fitting name for a small company which, after barely six years in existence, has already established a firm niche for itself in the specialist geotechnical contracting market.
The field of engineering is not well understood by many people. Children as well as some adults - especially in the rural areas - have no idea what engineering is all about. They do not have role model engineers to look up to. They know what teachers and doctors do, but not engineers. They get a lot of information about the lifestyles of musicians and artists in all media forms, but not in engineering.
