Geotechnical Investigations
& Pile Load Testing

Steel is a known commodity — we know how it reacts to loads, and we know how much it costs. Soils, however, are unique to every site. The less we know about the subsurface conditions and how they will interact with foundations, the more unnecessary steel will end up underground. Whether you are developing a 2MW facility or a +300MW facility, G2 knows how to maximize your return on foundation investment.

At G2, we understand the challenges of balancing design investment. A geotechnical investigation should be configured to meet the current needs, whether a solar project is in the feasibility, development or EPC phase. Not all testing and engineering is appropriate or necessary for every project or phase. We prefer to customize geotechnical and foundation testing and engineering services based on the client’s goals and the known subsurface conditions, with an emphasis on identifying those services that will have the greatest potential to reduce overall cost to the specific project.
