A few words about us

Since 1990, KGA Geotechnical Limited has been providing specialist geotechnical engineering consultancy services to the wider Auckland area. In 2012, a Christchurch office was formed to serve the Christchurch community as part of the earthquake rebuild and ongoing development.
The team at KGA are an enthusiastic, diverse and dedicated group of geologists, engineering geologists and geotechnical engineers ranging from graduates to senior professionals with a total of over 200 years of experience. Team members are from not only New Zealand but from all over the world, including Asia, Europe and Africa, and the Directors of the company have had extensive experience at a senior level in other organisations in New Zealand and overseas. This extensive range of backgrounds and experience provides us with a broad knowledge base that enables us to provide optimum geotechnical solutions for any construction project.
Our key philosophy is to work with our clients to achieve an optimum solution to any building project that is feasible, technically sound and cost effective. We are not blinkered by our immediate brief, but instead, "look outside the square". This could be as simple as looking beyond the immediate site boundaries.
One of the key questions we ask ourselves is “is the project buildable”. With this approach we are often able to identify other potential problems and the information required to resolve them. While this may incur additional cost at the outset of a project, from our experience, dealing with possible difficulties during the initial investigation and design stages will lead to cost savings during construction.
