Geotechnical
BFW offers some of the most complete and comprehensive Geotechnical Engineering services. Our expertise includes transportation infrastructure, foundation investigations for industrial and commercial buildings, towers, landfill permits, design of earth dams in addition to experience in auger cast and H pile designs. We have conducted geotechnical investigations throughout the Midwest and Southeast, and have been exposed to a wide range of geologic settings with a variety of subsurface conditions and problems to be solved.
BFW maintains a full-service soils and construction materials testing laboratory accredited by AASHTO Accreditation Program (AAP) and validated by the USACE. Our laboratory staff are able to meet deadlines and develop new test methods based on the needs of our clients.
In addition, our geotechnical engineering team consists of licensed professional engineers, and a full-time technical staff solely devoted to drilling services and geotechnical reporting.
