Practical Workshop and Field Training
Practical Workshop and Field Training tests hands-on competence and safe work habits in masonry, carpentry, plumbing, electrical work, concreting and surveying. You should be able to select tools, follow a method, take measurements, record results and interpret simple tests.
Workshop expectations
- Masonry: set out a corner, check level and plumb, use the specified mortar and joint thickness, and finish joints neatly.
- Carpentry and plumbing: measure twice, cut once; check squareness; use the correct joint or fitting; pressure-test plumbing lines.
- Electrical: isolate the supply, use insulated tools, make secure terminations and test before energising.
- Concrete: weigh or gauge materials accurately, mix uniformly, fill moulds in layers, compact and cure cubes under standard conditions.
- Surveying field work: close traverses, book readings neatly and verify calculations.
Worked example
A 150 mm concrete cube is tested at 28 days and fails at 450 kN. Cube area = 150 × 150 = 22,500 mm². Compressive strength = 450,000 N / 22,500 mm² = 20 N/mm². This corresponds to an M20 characteristic strength, but a single cube result must be judged against the acceptance criteria, not just the grade name.
Traps
Do not test cubes without proper curing and surface preparation; do not confuse failure load with stress; do not leave out the safety check before energising electrical work; and do not record field readings without checking for parallax, verticality and zero error.
