Andy O’Sullivan

Andy is a gregarious character with the rare gift of seeing both the problem and innovative solutions before others. He is the founder, Director, and heart of Andy O’Sullivan.  For over 30 years, he worked as a Chartered Engineer, honing his expertise and approach on medium to large, heavy civil engineering projects with main contractors, specialist geotechnical firms and international consultants.

Frustrated with the ponderous procedures of larger organisations, he established Andy O’Sullivan (aka A O’Sullivan and Associates Ltd) in 2018 to enable more nimble and closer collaboration with clients. He was encouraged to directly offer his industry-leading design approach and expertise. People wanted his quick thinking.

Andy has broad detailed design experience across geotechnical seismic foundations for buildings and infrastructure, soft soil engineering, highway embankment design, as well as innovative support of excavation and temporary works.

The combination of local and international experience across speciality fields of construction, management, engineering risk and design underpins Andy’s thorough, considered engineering solutions. He is well respected within the geotechnical community across New Zealand as an expert in micro-tunnelling, ground improvement, site characterisation and soft soil engineering.
