Estimates for a small start in Australia, not guarantees.
What it is
You visit building and land sites to take soil samples with hand augers or a small drill, record what you find, and do simple field tests. Samples go to a accredited laboratory, and you pass the results on to the client or their engineer.
Your first three steps
- Contact local geotechnical and environmental consultancies to ask what sampling help they need and what training they expect
- Get your ABN, public liability insurance and site safety basics such as a white card
- Buy a basic sampling kit and ute set-up, then offer a trial job to one or two consultants
Who pays
Builders, developers, surveyors, civil contractors and environmental or geotechnical consultancies that need sampling done.
How it makes money
Charge per site visit, per sample point or per hour, plus travel. Regular work from a few consultants can keep your diary steady.
Skills that help
- Comfortable with physical outdoor work
- Careful record keeping and labelling
- Reading site plans and following sampling instructions
- Reliable and safe on construction sites
Watch out for
- Public liability and, if you give advice, professional indemnity insurance
- White card and site induction requirements, check your state's rules
- Always check for underground services (for example Dial Before You Dig) before digging or drilling
- Contaminated land sampling often needs a qualified person, check what you are allowed to sign off
- Samples must be handled and labelled correctly or results may be rejected
