Course Summary

This Two Day course is worth

  • 2 CPD points - ECSA

Concrete is a highly variable material and its properties can be modified to suit the individual requirements of a structure or an environment.
Decisions regarding the selection of concrete component materials are frequently left to the contractor, and the resulting concrete properties may result in excessive shrinkage and cracking, for example, even if the concrete satisfies a rudimentary specification.

The course will ensure a better understanding of what can be achieved with concrete, and how it can accommodate the needs of a specific structure.
The Speaker

Bruce Raath matriculated at the Durban high School and obtained a Degree in Civil Engineering from the University of Kwa-Zulu Natal in 1970. He worked for the then South African Railways for a period of 10 years doing both maintenance and construction work. After a period in consulting with Webb and Partners in Durban, he lectured at the Durban University of Technology (then M L Sultan) and was senior lecturer in structural design and theory of structures.

In 1998, he was co-founder of the concrete testing and consulting firm Contest in Durban until he rejoined the C&CI as Education and Training Manager in 2006. He has since retired from the C&CI and formed his own consulting and training practice in construction materials and structures.

Course Details



  • Relationships between parties to a civil engineering contract
