Improvements to ventilation, lighting and daytime temperature were achieved by fitting a new roof to the Pietermaritzburg market without any disruption of market activities From the time of the commissioning of the Pietermaritzburg National Fresh Produce Market in 1972, there was dissatisfaction with the internal climate of the 12 350 m2 bulk sales hall, which was detrimental to proper storage and marketing of fresh produce. The project to improve this situation was the winner of a Pietermaritzburg Branch Award for Excellence in Civil Engineering.
Existing legislation, guidelines and published methodologies for public participation in the environmental field, and waste management in particular, are woefully inadequate. This paper suggests a way forward. The advent of democracy and heightened environmental awareness in the 1990s in South Africa has spawned considerable public pressure for environmental projects and particularly waste management projects. While there are a number of publications and public participation scoping and facilitation consultants, very little guidance exists for the practising engineer. If one is unfamiliar with public participation, how does one go about incorporating public participation in a civil engineering project?
The paper reviews the need for long-term environmental research at universities in the light of the needs of South Africa and the benefits that can be obtained from such research The unprecedented population growth, which is still outpacing the production of food in Africa (FAO, 1995), and the uneven distribution of resources coupled with the widening gap between the developed and the developing world are all facts that cannot be ignored.
With many countries facing severe water shortages, re-using water for industrial and irrigation purposes is gaining ground Wastewater reclamation, recycling and re-use serve an important function in water resources management by providing a means to produce quality source water for irrigation, industrial and urban water requirements throughout the world. Many industrialised nations face growing problems associated with guaranteeing an adequate water supply. Increasing costs of municipal and industrial wastewater disposal for water quality protection and pollution abatement have also catalysed interest in water reuse.
The paper descriptionbes the planning and construction of the South African Railways' new mechanical workshops at Koedoespoort, seven miles east of Pretoria. The total estimated cost of the project is over 12 million pounds and at the time of writing 6t million pounds have been spent. The need for new workshops, the selection of site and the basic principles of layout are briefly discussed, as well as the liaison required between the departments responsible for the planning and design. The construction work involving earthmoving, provision of services and erection of buildings is descriptionbed in some detail. The design of the major buildings and structures is not dealt with. Some unit costs are given.
