Geotechnical Engineering

The most fundamental aspects of any development project are the subsurface materials, soil and rock, and the interaction between the structure and these materials.  It is vital to have a design and construction team member who can help to bridge the gap between the raw site materials and the finished structure. PSI provides the owner with the geotechnical expertise and the integrated personnel and services to help make your project a success.

PSI’s staff of geotechnical and technical professional and our numerous office locations across the United States results not only in local experience but also in vast technical and construction knowledge and experience that can be brought to bear on our clients’ projects.  PSI maintains a fleet of drilling and CPT equipment that can perform a variety of sampling and in- situ testing and geophysical testing equipment in strategic locations across the country.  PSI has accredited geotechnical and construction materials testing laboratories capable of performing a wide variety of tests necessary for characterization of the site geo materials.  All of this is supported by our internal quality assurance and safety plans with the goal of providing our clients with the subsurface and site information necessary for a successful project.
