Nelson Geotechnical The ground beneath our feet. The little corner of the planet upon which we stake our claim and put our roots down. The foundation upon which we build our dreams and settle in to the structures that support our family and communities. For 4.5 billion years persistent and prevailing forces have been acting upon our Earth, shaping, changing and impacting the sites upon which humans impose their vision.

At NGA it is our passion to understand the complex and minutia details of your unique site and to engineer the systems that will ensure the long term stability of your structures.
