Site Visit

Starting from site visits needed to gain an understanding of the area in or on which the engineering will take place.

Geophysical Exploration

Soil exploration and geophysical exploration to obtain information about the soil conditions below the surface. Our methods of observing the soils below the surface, obtaining samples, include standard penetration test (SPT), which is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. The test procedure is performed in accordance with ASTM D1586; our drilling equipment that performs the SPT can be adapted to perform rocking coring used in mineral exploration operations to help determine the rock type and amount of mineralization present, Tri- coning, test pits and trenching.
