Observation
A good number of candidates did well by showing:
- the substructural elements ( i.e earth filling, hardcore filling, concrete floor slab and mortar screed finish ) with conventional symbols;
- in details, the timber roof truss members and labelling the key parts.
Hower, it was observed that the:
- foundation concrete strips were drawn out of proportion;
- substructural walls were shown to cut through the floor;
- wardrobe and semi-circular arch were missing on most of their drawings
. walls in sections were not hatched;
- doors and windows were the incorect type in most cases.
The expected response to question 1 is as given below:
