Geotechnical Services


Exploration, Sampling & Testing  (click to learn more)

Exploration involves characterizing the arrangement and relevant physical properties of the soil and rock strata and groundwater conditions that underlie a site. This is accomplished using a variety of methods including: research of existing data, site reconnaissance, soil borings, core drilling, in-situ testing, laboratory testing, geophysics and instrumentation.

Analysis & Evaluation  (click to learn more)

Geotechnical engineers analyze and evaluate the information from the subsurface exploration and formulate a model of the soil and rock conditions. This model allows predictions of subsurface behavior and interactions between structures and the subsurface. Some behaviors and properties that commonly are modeled include: bearing capacity, settlement, seismic response, and slope stability. These assessments are used in many situations including: planning and design of new structures, evaluation of subsurface conditions during construction, and failure investigations.

Recommendations & Design  (click to learn more)

Recommendations are developed for geotechnical design parameters, construction methods, and foundation systems that are tailored to the specific site characteristics and project requirements. Recommendations can range from design parameters (i.e. foundation bearing capacity), to construction procedures (i.e. clay liner placement methods for a solid waste landfill), to a complete set of design documents (i.e. plans and specifications for construction of a tied-back retaining wall).

Construction Phase Testing & Monitoring  (click to learn more)

Soil and rock conditions are inherently variable. Natural events, such as flooding, sinkhole development, or earthquakes, and human activities, such as filling or previous construction, can significantly change the soil and rock conditions. As such, the subsurface conditions encountered during construction may vary from the conditions encountered in the exploration phase. Construction phase geotechnical services serve to further define these conditions and to develop appropriate design changes when necessary. Construction phase geotechnical services also provide confirmation that the geotechnical materials and systems utilized for a construction project are consistent with the project specifications and the design intentions.
