GEOTECHNICAL ENGINEERING The branch of Civil Engineering concerned with the behavior of soils and the design of foundations. Geotechnical Engineering studies include: subsurface investigations and laboratory testing, enabling the design of slopes, foundations for structures, embankments, shoring and bracing for deep excavations, earth retaining structures and other foundation systems. Geotechnical Engineering services include feasibility studies, preliminary and detailed geotechnical reports, compaction testing, foundation inspection during construction, final inspection reports, investigation of causes and repair of earth failure mechanisms, critique of proposed grading and foundation plans, assistance and presentation of findings to controlling agencies. Earthquake Geotechnical Engineering studies include the evaluation of earthquake related distress, seismicity, site response analysis, ground motions, study of the dynamic behavior of soils, liquefaction potential, and the evaluation of dynamic loads on slopes, retaining walls, earth structures and foundations. In adverse soil conditions, Geotechnical Engineers utilize many soil improvement methods, including; shear pins, dewatering, underpinning, grouting and stabilization fill designs. |

ENGINEERING GEOLOGY The science concerned with the application of geologic knowledge, in the investigation and evaluation of naturally occurring soils and rock, for use in the design of civil works. Engineering Geology studies include: review of geologic maps, reports and aerial photographs, site reconnaissance, geologic mapping, subsurface exploration, and monitoring of ground conditions, such as movement, by instrumentation. |

Engineering Geology services include evaluation of parameters critical to slope stability, seismicity, fault investigations, ground water studies, professional geotechnical opinions and input for Environmental Impact Reports. In adverse soil conditions, Engineering Geologists provide Geotechnical Engineers with pertinent geologic information for the design of soil improvement methods, including; shear pins, dewatering, underpinning, grouting and stabilization fill designs.
