The tools and instruments used in building construction.
Warming – up
1. What tools and instruments do you know ?
2. What tools are mostly used in building construction?
3. What do you think about functions of tools?
I. Look at these diagrams of the tools used by tradesmen working on a building site:
Now copy and complete the table with the correct tools or combination of tools for the jobs:
| Tradesman | Job | Tool (s) | |
| a) Carpenter | drilling holes in wood | ||
| b) Bricklayer | mixing mortar | ||
| c) Plasterer | smoothing the plaster on a wall | ||
| d) Carpenter | cutting wood j | ||
| e) Plumber | cutting metal pipes | ||
| f) Electrician | cutting electric cables | ||
| g) Carpenter | making a mortise-and-tenon joint | ||
| h) Plumber | smoothing metal surfaces | ||
| i) Electrician | removing the outer sheathing of wire | ||
| j) Carpenter | turning screws | ||
| k) Decorator | painting surfaces | ||
| 1) Bricklayer | cutting bricks | ||
| m) Plumber | tightening nuts | ||
| n) Electrician | twisting strands of wire together | ||
| o) Carpenter | smoothing wood surfaces | ||
| p) Bricklayer | laying mortar on | ||
| bricks | |||
| q) Carpenter | removing nails | ||
Now make sentences like the example:
A brace and bit is a tool for drilling holes in wood.
II. Look at these drawings of instruments:
Now make sentences from this table:
| A An | lighting engineer structural engineer bricklayer acoustic engineer heating and ventilating engineer carpenter electrician | uses | a square a plumb-bob a hygrometer a strain gauge a voltmeter a sound pressure meter a daylight factor meter a thermometer a spirit level a steel tape |
| to | check verticality. measure the illumination from the sky. measure the sound pressure. measure the relative humidity. check vertical and horizontal work. measure the temperature. measure the voltage of a circuit. check squareness. measure distances. measure the strain on a structure. |
Use thetable again to make sentences like thefollowing:
may by means of
Verticality can be checked by using a plumb-bob.
