The questions to expect
Tell me about the groundworks you've done most of — drainage, kerbing, concreting, foundations. Pick one job and walk me through it.
Specifics prove experience: pipe sizes, laying to falls, testing drains, pour sizes. One job told properly beats a list of everything.
Tell me about a time an excavation didn't feel right — ground moving, water, something in the ground that shouldn't be there.
Trench collapses and service strikes kill groundworkers — show you stopped, got out, and reported. That instinct is exactly what's being tested.
You work around diggers and dumpers all day. Tell me about keeping yourself and others safe around plant.
Eye contact with operators, exclusion zones, never walking behind a machine, banksman signals if you're ticketed. Concrete habits, not 'I'm always careful'.
This is heavy outdoor work in all weathers. What's your record for turning up and grafting through a hard week?
Give evidence: attendance, winters worked outside, a supervisor who'll vouch for you. Reliability is the main thing this interview is checking.
Before you put a shovel in the ground — what checks happen first?
Permit to dig, service drawings, CAT and genny scan, hand-digging near marked services. Knowing the sequence cold marks you as safe to hire.
How do you lay a drainage run to falls and prove it's right?
Laser or boning rods for the gradient, bedding material, and an air or water test at the end. Mentioning testing without being asked shows real site time.
What tickets do you hold — CSCS, dumper, roller, streetworks — and what would you add first?
CSCS is the entry requirement; plant tickets and NRSWA streetworks make you more useful. Naming the next ticket you want shows you're staying in the game.
If you're shown a new material or method you've not used before, what do you do?
Ask to be shown properly, read the spec sheet, do the first one supervised. Never bluff on site — saying exactly that is the right answer.
Machines with GPS grade control and laser levels are doing more of the setting out. How comfortable are you working with that kit?2026
Any experience with laser levels, pipe lasers or GPS-guided plant is worth naming. If none, show quick-learner proof — the kit is on every big job now.
Why groundworks — first trade in, out in all weathers, and the job everything else gets built on?
Honest pulls land: steady demand, being outdoors, seeing a site rise from your trenches. Wanting tickets and progression makes you a keeper.
Which cards and tickets do you hold — CSCS and any trade-specific ones — and are they all in date?
Bring the actual cards. Know every expiry date, and if something's lapsed, say what's booked to renew it — an expired ticket can't start on site.
Tell me about a time you spotted a hazard on site before it hurt someone. What did you do?
A real, small example is perfect: what you saw, making it safe or fencing it off, and telling the supervisor. Reporting is the part they're listening for.
