	Before any construction or design work can be completed at a potential dam site, conducting geotechnical subsurface and onsite material exploration is essential. These explorations consist of both invasive and non-invasive sampling methods. Invasive geotechnical sampling methods may include drilling boreholes and taking core samples from the overburden and bedrock within the footprint of the dam and its appurtenances, taking soil samples from open pits, or using correlative field tests. Non-invasive geotechnical sampling methods may include but are not limited to using geophysical methods involving emitting ground penetrating radar or creating mechanically induced seismic waves.

	The intent of the geotechnical investigation is to characterize the foundation conditions and uncover any potential problems at the project location.
