We move 'mountains'
by optimising geotech, earlier.

Over the past two and a half years, Andy and his team have consistently delivered innovative and efficient design solutions to a wide range of complex, geotechnically related, challenges on the City Rail Link Project.

Nigel McCreight - Engineering Manager, Auckland City Rail Link, Link Alliance

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.

Alastair Blackler - General Manager, Abergeldie Complex Infrastructure

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.
