Geotechnical Engineering

We work with you to provide comprehensive reporting on the design, analysis and construction
of your site.

Our Geotechnical Engineers are specialists at solving ground related problems with optimal construction solutions.

Based on our local knowledge, we can investigate and monitor ground conditions, respond rapidly to infrastructure defects and execute detailed designs that display a high commitment to buildability.

During the construction phase our team can give guidance on source materials, in-situ testing and temporary works design & certification.

From the outset of your project, we can offer advice that analyses risk, buildabilty, cost effectiveness and sustainability.

Where the earth lies, so do our solutions

When designing and constructing infrastructure, it is imperative to study and understand the relationship between the infrastructure and the underlying and surrounding ground conditions. That’s where we come in – with over 29 years of Geotechnical Engineering experience, we can read, monitor and predict what lies beneath the surface.

During the construction phase of a building project, we provide advice on source materials, in-situ testing as well as design & certification of temporary works. Our engineers use a suite of methods to determine geotechnical parameters including Plate Load Testing (PLT), Light Weight Falling Deflectometer Testing (LWFD), Panda in-situ penetrometer tests, and many others. We provide modelling, design and certification of temporary and final cut batter and fill batter stability, hard stand design for safe crane lifting and machine stability, and design of temporary pavements. From the outset of your project, our engineers will work with you to provide comprehensive geotechnical engineering reports to meet project objectives in line with the desired design life.

When it comes to geotechnical solutions, our clients trust us in solving ground related problems while considering risk, constructability, cost effectiveness and sustainability. With our industry knowledge, we can:

  • Identify and manage geotechnical problems through innovative geotechnical design.
  • Respond rapidly to situations which arise on existing infrastructure as a consequence of geotechnical defects.
  • Investigate and monitor ground conditions and three dimensional movements.
  • Develop a buildable detailed design which considers constructability and sequencing.
  • Provide construction support and project sign-off.
  • Provide scientifically sound data and correlations to support specification variations.
