The following weaknesses were observed from the candidates’ work:
-
inability to represent graphically, the reinforced concrete flat roof in conjuction with the pitched timber roof, both in section and elevation;
-
difficulty in labelling and dimensioning the key elements of the building;
-
failure to indicate on plan, the position of doors using the appropriate conventional symbols.
To overcome these weaknesses, candidates should be taught on the :
- types of roof and their construction methods;
- proper method of labelling and dimensioning of building elements;
- conventional symbols used to represent different types of door in plan.
