Practical Project Work and Viva
Practical Project Work and Viva tests whether you can plan, execute, check and explain a small construction task.
Project sequence
- Read the drawing; prepare a material list; set out; check levels; complete work in sequence; cure; clean up.
- Quality checks: cube test, slump, plumb, level, mortar joint thickness and cover.
- Records: site diary, measurement sheet, photographs and test reports.
Worked example
M20 concrete cube results at 7 days average 14 N/mm². The 28-day target is 20 N/mm²; 7-day strength is usually about two-thirds of 28-day strength, i.e. 13.3 N/mm². A result of 14 is close to expected, but acceptance depends on 28-day results and IS 456 criteria. Reason: do not accept or reject on 7-day results alone.
Viva
Be ready to explain why you chose a mix, how you cured, what you would change and how you kept safe. Use the actual project, not a textbook answer.
Traps
No records; curing for one day only; guessing at viva; and claiming a test was done when it was not.
