FAQ

Have Questions? We’ve Have Answers

Do you have questions about our services or processes? Here are a few common ones our clients ask before starting their projects with us.

We specialise in geotechnical and environmental engineering, offering investigations, analysis, design, and testing for projects of all scales.

We’re based in Sydney and deliver projects across Greater Sydney and New South Wales.

A geotechnical investigation is typically required during the planning and design stages of a project to assess ground conditions and inform appropriate foundation and earthworks design. It may also be required to support development applications, satisfy council or regulatory requirements, or address specific ground-related risks such as bearing capacity, settlement, slope stability, and groundwater conditions. Early investigation helps identify potential constraints and reduce construction risks..

Yes. Our team has extensive experience navigating approval processes across a wide range of projects. We prepare reports that comply with the requirements of local councils and relevant state authorities, including Sydney Water, WaterNSW, the EPA, Transport for NSW (TfNSW), and the NSW Department of Planning and Environment.

We work with developers, contractors, consultants, councils, government agencies, and private clients across residential, commercial, and infrastructure sectors.

Sydney West Link Upgrade

Geotechnique provided geotechnical investigations, subsurface drilling, and pavement design for the Sydney West Link upgrade. The project involved complex soil conditions and required slope stability and foundation analysis to ensure long-term structural integrity under high-traffic conditions.
