Geotechnical Information

Definition - What does Geotechnical Information mean?

Geotechnical information is any information that describes the condition of the ground through which a trenchless construction project will pass. It includes factors like soil type, presence of rocks, groundwater conditions and other existing installations in the surrounding area. A thorough analysis of the work site is critical to enable contractors to plan the trenchless project and to choose the best equipment for the conditions with the help of a geotechnical report, which comprises the information obtained through analysis. .

Trenchlesspedia explains Geotechnical Information

Geotechnical information is prepared by engineers based on analysis of soil samples, Ground penetrating radar (GPR) results and documentation from previous projects in the area. Soil samples are obtained by digging wells along the projected path of the pipeline installation and then performing lab analysis to determine the exact soil conditions. Geological engineers draft reports, which are reviewed by the construction team in order to make decisions about the most appropriate trenchless equipment to use. In addition, results of the geotechnical information may also inform a decision to relocate the route of the pipeline to avoid an obstruction and thus save time and money.
