Increased trained participation by Coloured persons (and Asian and Black persons, for that matter) in technical aspects of national development is essential to the long-term prosperity and stability of the national economy. An increased number of coloured graduates in engineering and other construction-related disciplines in particular is required.
There are many statistical indicators of the lack of trained Coloureds. For example, over the last 10 years only 0,7 per cent of civil engineering graduates of Southern African universities were Coloured. The reasons for the limited formal education in suitable disciplines lie in primary factors such as :
- An inferior school education
- Low matriculation rate
- Not being able to afford to go to university
- Having difficulty for other-than-educational and financial reasons in getting to university
- The choice by university entrants of courses other than construction-related due to a perception that status and financial rewards lie in other directions
- Financial support by employers and other interested bodies
- Removal of the barriers inherent in the educational system
- Measures to increase the knowledge among Coloureds of an engineering career and to increase the incentive to them to choose this career.
Groter opgeleide deelname deur Kleurlinge (en Asiërs en Swartes) in tegniese aspekte van nasionale ontwikkeling is noodsaaklik vir die vooruitgang en stabiliteit van die nasionale ekonomie op die langtermyn. In die besonder word meer Kleurling-graduante in ingenieurswese en ander konstruksievewante dissiplines benodig.
Daar is talle statistiese aanduidinge van die gebrek aan opgeleide Kleurlinge. Byvoorbeeld, oor die afgelope 10 jaar was net 0,7 persent van graduante in siviele ingenieurswese aan Suid-Afrikaanse universiteite Kleurlinge. Die redes vir die beperkte formele onderrig in geskikte dissiplines lê in primêre faktore soos :
- 'n Mindewaardige skoolopvoeding
- 'n Lae matrikulasiesyfer
- Die koste om 'n universiteit by te woon
- Ander probleme (nie vewant aan opvoeding of geldtekort nie) om 'n universiteit by te woon
- Die keuse deur voornemende universiteit-studente van kursusse wat nie aan die konstruksiebedryf verwant is nie, te wyte aan die persepsie dat status en geldelike vergoeding in andere rigtings lê.
- Finansiële ondersteuning deur werkgewers en ander liggame wat belangstel
- Die verwydering van die hindernisse wat 'n deel van die opvoedingstelsel vorm
- Stappe om die kennis van 'n loopbaan in ingenieurswese onder Kleurlinge uit te bou en om hulle aan te spoor om dié loopbaan te kies.

Hugh Watson, who retired in February 1978 as Director of Engineering Services in the Public Works Department, was born in Sea Point and educated at the Diocesan College, Rondebosch. He went on to the University of Cape Town with a Jagger Scholarship and after graduating four years later in civil engineering joined the PWD in February 1935 in its Structural Engineering Branch at the Head Office.

Many tests on reinforced concrete skew slabs have been reported and various methods of analysis have been put forward. However, little information is available on the test behaviour of skew slabs prestressed in two directions. To study the behaviour of a prestressed skew slab of uniform thickness a suitable slab model was designed and tested in the laboratory. This paper focuses on the serviceability and ultimate limit state performance of a two-way prestressed slab, gives some details of analysis and discusses the testing procedures proposed by CP 110 : Part 1 : 1972.

The paper described the design and construction of the 300 m high multi-flue chimney at Duvha Power Station in the Eastern Transvaal. This was the first of a number of chimneys of comparable height to be constructed at Escom's new power stations to meet strict pollution control requirements. The paper dealt with the reasons for the choice of a multi-flue configuration and covered those aspects of the design and construction in which special problems had to be overcome. Special attention was paid to the choice of suitable lining materials to meet the corrosive environment inside the flues and the design approach to resist wind loads and particularly the aerodynamic interaction between structure and wind. Proposals to instrument the chimney to obtain data about flue gas composition and corrosion and new information about dynamic wind pressures and response were described.
