Observation
To a scale of 1:50, draw the detailed section M – M of the building from the foundation tothe
roof.
Majority of candidates did well by
- graphicallyrepresenting and identifying the timber roof members correctly;
- showing the roof pitched to the specified degree of slope on drawing.
However, it was observed that some of them:
- draw deep strip, wide strip and pad foundations instead of ordinary strip foundations specified;
- could not show the ground floor elements (earth fill, hardcore fill, concrete floor slab, floor finish) correctly;
- failed to hatch the walls in section;
- showed other door types instead of panelled wooden door specified.
The expected response to question1 is as given below:
