"The science and technology sectors hold great promise for government's development ambitions and need to be given far more attention and support than they currently receive," says Minister Naledi Pandor. Speaking in her budget debate on Tuesday 24 May, she argued for increased resource and policy support to strengthen excellence. This should be particularly in disciplines and sectors that have the potential to make a contribution to improving the country's development status, expanding economic growth and changing the quality of life of individuals and communities.
Paul van der Merwe was born and also grew up in Stellenbosch. From standard two (now grade 4) he was a boarder at St George's Grammar School in Cape Town. He studied at the University of Cape Town from 1953 and became a land surveyor. As the family grew, however, he realised that his career would often take him away for long periods of time. He then decided to return to the University of Cape Town in 1961 to study civil engineering.
This book was reviewed in the September 2010 edition of Civil Engineering (p 75). It has since come to our notice that, due to the demand, bookshops are starting to run out of copies.

Soil conditions in South Africa tend to differ from those of Europe and North America where soil mechanics mainly developed. The drier climate often results in stiffer desiccated soils which give rise to problems such as collapse or heave. Also, predicting future moisture changes in partially saturated soils is very difficult. Piles in rock sockets and the problem of uplift of driven cast-in-situ piles are discussed briefly. Finally. it is stressed that in soil engineering as much as in any other branch a thorough understanding ofthe principles involved and their limitations is of the greatest importance.
For some time road engineers have been concerned that the variability inherent in road construction materials and their sampling and testing has not been logically and consistently catered for in the road construction process or in construction control. Over the last few years various process and acceptance control plans for road construction, based on stochastic procedure, have been developed, both in South Africa and abroad. In this paper the first large-scale South African application of statistically oriented acceptance control procedures to a major road construction project is examined and it is concluded that such procedures promise to be of benefit to both the client and the contractor.
