OUR APPROACH
Understanding a site’s ground conditions early helps avoid risk, delay, and additional cost.
We take a proactive, integrated approach, working closely with civil and structural teams to ensure design solutions are safe, sustainable, and cost-effective. Our engineers use advanced modelling and geotechnical analysis tools to deliver reliable recommendations that stand the test of time.
Through collaboration and technology, we help clients reduce uncertainty, improve sustainability, and deliver compliant, buildable solutions.
FREQUENTLY ASKED QUESTIONS
It is best to commission a geotechnical investigation as early as possible. Prompt investigation helps identify ground conditions, risks, and opportunities, ensuring your design is safe and cost-efficient.
A Phase 1 assessment involves a desk study and site inspection to identify potential contamination risks. If issues are suspected, a Phase 2 assessment includes intrusive ground investigations and laboratory testing to confirm conditions and propose remediation measures.
