Category:321 Geotechnical Engineering

The geotechnical section of Construction and Materials provides geotechnical services for the department including laboratory and field testing as well as subsurface drilling. This section obtains and interprets the subsurface information needed to design highways and bridges. Soils and Geology personnel also investigate various geotechnical matters including foundation stability and settlement of embankments, slide corrections, subgrade and base stabilization, bridge and wall foundations, sinks and mine subsidence, and the use of new technology and products. Geotechnical serves as a contact regarding geotechnical problems, new products, specifications, training programs and implementation of new products and procedures. This section also participates in proficiency sample programs and inspections by the National Institute of Standards and Technology.
