(b) With the aid of sketch illustrate the 3:4:5 method of setting-out a building and label the folowing:
(i) building line;
(ii) set back.
(c) Explain the method of weathering clay soil.
Observation
Most candidates were able to:
- state three uses of Engineering bricks.;
- explain the method of weathering clay soil.
However, some of them were not able toshow a sketch to illustrate the 3:4:5 method of setting-out a building and label the following:
(i) building line;
(ii) set back.
The expected response to question 2 (b) is as given below
