Geological Survey

Definition - What does Geological Survey mean?

Geological survey is conducted for the purpose of studying the composition of materials that compose the earth. Geology plays an important role in conducting geotechnical investigation for trenchless methods such as horizontal direction drilling (HDD), microtunneling and pipe jacking.

Before a method is selected, it is necessary to understand the soil and rock characteristics for conducting a successful trenchless installation.

Trenchlesspedia explains Geological Survey

Geology includes examining the composition, property, formation, and changes that geological formations undergo naturally or when subjected to certain forces, pressure or loading conditions. The information can be obtained by visual survey, landform study, boreholes, remote sensing, ground penetrating radar (GPR), aerial survey, global positioning system (GPS), and laser scanners.

Material can also be studied in the lab by studying rocks and conducting laboratory tests. There are many survey companies that conduct geological surveys for companies that require geotechnical reports for bidding on projects.
