Geotechnics has been one of ARQ’s key areas of specialisation from the outset and the past 17 years have seen us active in a number of countries in fields as diverse as arch dam foundations, deep excavations for high-rise buildings and piled foundations for large bridges.

Providing independent services to a significant diversity of clients in the private and public sector, ARQ’s geotechnical engineers also offer support internally to our bridges, dams and structures divisions.

While we have found hand-calculations, or simple spreadsheet models most appropriate to develop judgment in respect of certain geotechnical problems, sophisticated analytical methods have also often allowed us to design ambitious and innovative geotechnical systems that have always been demonstrated to behave as predicted. Design-compliance field measurement is regularly applied to complete the investigation-analysis-design loop, or simply for the purpose of quality assurance, while the requirements of OHS and environmental legislation are rigorously observed during investigations to ensure safety and minimum disturbance to the environment.

Heading up our Geotechnical division is Alan Parrock, whose 40 years of experience is supported by 8 geotechnical engineers and engineering geologists. We believe in putting effort into the development of the knowledge and expertise of our people and we consequently encourage attendance and participation at symposia, conferences and other significant forums.

RAMMING INTO ACTION

With the ever-increasing demand for coal due to the construction of new Eskom coal fired power stations, Total Coal South Africa have expanded their Dorsfontein operation to mine other seams of coal in the area.
