Draw to a scale of 1:50, the detailed section X – X of the building from the foundation to roof.
A good number of candidates succeeded in:
- using appropriate conventional symbols to represent the key elements of the solid ground floor construction;
- showing the walls in section withg rendering/plastering on both internal and external sides.
- identifying the timber members correctly.
Observation
However, it was observed on their drawings:
- failure to show the strip foundations in the correct proportion to the thickness of the substructural walls;
- in ability to position the doors and windows correctly, to conform with what is on the floor plan;
- failure to show the mortar screed finish specified for the concrete floor slab.
. walls in sections were not hatched;
The expected response to question 1 is as given below:
