About Subsurface Investigation

This technical area provides method and procedural guidance concerning selection, planning, executing, contracting, quality assurance/quality control, inspection, interpretation, and report preparation for subsurface explorations involving transportation applications. The subsurface characterization techniques covered includes the in situ testing, the geophysical testing, and the laboratory test selection used to establish appropriate soil and rock design and construction parameters.
