oa Civil Engineering = Siviele Ingenieurswese - Practical experiences of piled foundations in expansive soils
The writer had listened to the above paper and while he appreciated the information furnished considered it unfortunate that a joint report by the various firms engaged in drilling for under-reamed piles was not possible, as various types of drilling and under-reaming equipment had been specially developed in South Africa for this purpose. The writer's department had been responsible for erecting eleven major schools and Government buildings in the new O.F.S. Goldfields area. These services, which had cost over 1,000,000, were founded on under-reamed piles, and no defects had become evident as yet. It should be noted that joints had been provided at various points in these structures to compensate for any differential movement in the piles.
