We move 'mountains'
by optimising geotech, earlier.

Andy O Sullivan had a great understanding of the contractors focus to provide a safe and efficient solution for the shaft works on the Saint Marys Bay Project.  Their willingness to investigate change and be flexible during the construction phase allowed the project to realise opportunities and achieve a successful outcome.

The Andy O’Sullivan team developed the design for the temporary works as part of the Barber Grove ECI. This included several aspects of geotechnical design from retaining structures to specialist considerations associated with TBM works. The AOS team provided practical and progressive solutions in a demanding geotechnical environment and as a result, the well-considered designs bought real value to the project.

March Cato have enjoyed working with Andy O’Sullivan. We feel confident that we can pick up the phone at any time and get talking to a team who properly listen and take the time to understand the challenges we’re facing, so they can develop up a site specific, sensible and constructable solution to keep our jobs moving along safely.

Tony Mills - General Manager, March Cato

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

Andy has been able to bring specific knowledge from previous projects in Auckland, therefore with Andy and his team, we were able to optimise some design elements. By involving Andy O’Sullivan in the early stages of the design they were able to add value to the project.
