Frequently Asked Questions
A geotechnical site investigation assesses the soil, rock, and groundwater conditions beneath a site before construction begins. It helps determine bearing capacity, potential risks, and suitable foundation types. At Benchmark Geotechnical, our investigations comply with AS1726 standards to ensure reliable design data and safe, efficient construction outcomes.
A geotechnical report identifies ground risks early — such as weak soils, groundwater, or slope instability — which helps prevent costly surprises during construction. It also ensures compliance with council and engineering requirements under AS 1726 and other relevant Australian Standards.
For most residential or commercial sites, investigations typically take between 5 to 10 business days, depending on site conditions and laboratory testing requirements. Larger or more complex projects may take longer. At Benchmark Geotechnical, we prioritise efficiency without compromising quality or compliance.
We’ll need your site address, proposed development plans, and any available existing reports or drawings. This allows us to tailor our investigation to your specific design needs and regulatory requirements.
Pricing varies depending on site access, project scale, and testing requirements. We provide transparent, competitive pricing with no hidden costs.
A Benchmark Geotechnical report includes:
- Site and soil classification (in accordance with AS 2870)
- Borehole logs and laboratory test results
- Groundwater observations
- Foundation design recommendations
Slope stability and drainage advice
Our reports are practical, compliant, and ready for council or engineering submission.
Yes. We offer construction-phase support, including density testing, footing inspections, compaction verification, and fill certification. Our field technicians and engineers ensure the design intent is met from start to finish.
Absolutely. Our engineers specialise in slope stability assessments, retaining wall design parameters, and remediation strategies to ensure safety and durability in challenging terrains.
We work with all three. Benchmark Geotechnical partners with builders, architects, engineers, developers, and private clients, ensuring every project — from small residential builds to large infrastructure — is delivered with precision and integrity.
We operate to strict Australian Standards (AS 1726, AS 2870, AS 2159, and AS 3798) and maintain rigorous internal review processes. Every report is verified by qualified engineers, ensuring accuracy, reliability, and professional accountability.
Yes — where feasible, we offer priority and express services for urgent projects or council requests. Contact our team to discuss your timeframes, and we’ll accommodate your schedule wherever possible.
