Q1) What are geological surveys?

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.
