We move 'mountains'
by optimising geotech, earlier.

Design and detailing of the soil – structure interaction for the Main Wharf North project was a considerable challenge for all involved. The ground improvement was required to stabilise the existing fill and alluvial soils, provide the majority of the lateral restraint for the entire wharf and back span slab in a highly seismic zone, all without excessive restraint of thermal and shrinkage actions. Andy and his team provided strong leadership in this complex interface, relentlessly driving efficiency and value in the solution.

Daniel Patten - Engineering Manager, McConnell Dowell

We have worked with Andy and his team through the past two earthwork seasons on a number of challenges that have been encountered within our project. From stabilisation of large cut slopes in challenging ground. The solutions have been realistic, reasonable and constructable and a real ‘value add’ has been having some of our team regularly working out of Andy’s offices in true collaboration.

Andy O’Sullivan have provided Abergeldie innovative temporary works designs and geotechnical assessments reducing cost and programme on many of our construction projects.

Andy O’Sullivan are easy to work with and quick to respond to our requests.

Alastair Blackler - General Manager, Abergeldie Complex Infrastructure

We have worked with Andy and his team for a number of years now and we keep coming back to them as their approach to geotechnical design is always practical and efficient. They do not shy away from challenging designs and will always go that extra mile to make sure their designs are constructable.

Tim Pervan - Engineering Manager, Heron Construction

Andy has always made time to work with us, often without prior notice. His team listens to what we want to achieve, then works collaboratively to develop innovative and cost effective solutions.
