Geologic and hydrogeologic investigations are essential to assess the suitability of a site. These investigations include descriptions of soil, rock, and groundwater conditions beneath a proposed site, and they provide assistance in identifying design elements that are needed to minimize environmental impact. We will coordinate drilling services, soil and rock laboratory testing and field testing. We also monitor field investigations and provide slope-stability analyses, foundation design, topographic and geologic mapping, grading plans and cost estimates for site development.
DiGioia Gray & Associates have geotechnical engineers and geologists that are highly experienced in the principles of engineering geology, hydrogeology, soil and rock mechanics, subsidence remediation, landslides, and mine fire investigations.
For many projects, soil is a finite and critical resource. Our professionals investigate and evaluate subsurface conditions with the intent of minimizing soil and foundation-related costs while maximizing the utilization of soil and rock resources. By performing thorough site explorations, we detect geologic and environmental hazards and other risks that can challenge site and project development. We also conduct geologic research, reconnaissance, feasibility studies, and hydrogeologic studies for our clients’ projects.
