In the geotechnical area our expertise covers all aspects of engineering and engineering geology for small and large civil engineering projects, from planning and investigation stage and feasibility studies, geotechnical investigation and interpretations through to design, construction surveillance and operational phases.

In the environmental area our expertise covers all aspects of preliminary and detailed assessments, preparation of remediation action plans and site validation. The range of projects include soil, groundwater and vapour assessment. These are carried out for the purpose of acquisition, divestment and determining risks associated with current site use or changes to a more sensitive site use.
