Draw to a scale of 1:50, the detailed section X – X of the building from the foundation to roof.
Most of the candidates performed well on the:
- graphical representation of the strip foundation and the substructural walls in section;
- identification of the timber roof truss members.
Hower, the following short comings were observed relative to candidates drawing:
- inability to represents graphically, the solid ground elements;
- failure to hatch the walls in section by using the appropriate coventional symbols.
The expected response to question 1 is as given below:
