We provide a broad range of geotechnical skills through our growing team including desktop studies; site investigations; design work and onsite construction management.  We can also provide value engineering services and independent reviews to provide innovation to projects and tender designs.

We would welcome the opportunity to provide our specialist skill set through pragmatic design and innovative thinking to deliver value on geotechnical engineering challenges.

Geotechnical Investigations

Our fundamental belief is that geotechnical investigations should be undertaken to confirm the ground conditions which means that we undertake investigations to target particular and project specific issues.  This pragmatic approach provides value for our clients and a more robust application of geotechnical engineering.

Risk Management

Whilst marginal land is becoming increasingly viable for development it tends to come with larger geotechnical risks.  Our geotechnical team identifies and quantifies geotechnical risks and provides design solutions to mitigate the identified risks. JDSi also provides the civil engineering design and site support to manage these risks throughout the entire project, providing our clients with a total package of risk management.

Ground Improvement Works

One of the key ways to manage geotechnical risks is through ground improvement regimes.  JDSi’s geotechnical team identifies, designs and verifies a broad range of ground improvement techniques to develop an efficient methodology to remediate a site.  By working closely with our civil engineers, we can develop “whole of project” solutions that consider staging of works, materials handling, contractor management and verification.

Value Engineering

JDSi provides value engineering services for contractors during the tender design phase of projects to identify risks and opportunities with the ground.  Our Principal Geotechnical Engineers all have significant experience in construction works and bring a pragmatic approach, which is supported by a solid theoretic foundation, to design and construction work.

Due Diligence For Land Acquisition

Through JDSi’s resources and extensive experience, we can provide initial assessment of the geotechnical conditions at sites for land development and (construction material) resource evaluation.  Our combined geotechnical and civil teams can extend the study to allow a robust assessment to be carried out before ground breaking investigations are undertaken.  Through JDSi’s experience and skillset, we can provide our clients with a preliminary and efficient assessment of potential development areas.  We also have the capabilities to provide ongoing services through the design and construction phases.

Expert Witness And Claims

Geotechnical and geological conditions often present the biggest risk on projects and unfortunately all projects do not go according to plan.  JDSi can provide independent advice on claims or expert witness cases; ranging from initial reviews and high level advice through to detailed discussions and review of particular claims.
