Collier specializes in geological investigations in support of rock-slope stability analysis, tunnel exploration and development (lithology, rock integrity, consolidation grouting, fracture inflow, etc.), bedrock fracture trace analysis, and geological research. Bedrock characterization is affected via graphical representation of outcrop and tunnel data, including stereographic projections, rose diagrams, histograms, and map illustrations.

Collier also conducts subsurface geological investigations using geophysical methods to provide a complete bedrock characterization, including unique and high-powered low frequency ground penetrating radar (LFGPR). In addition to stratigraphic and bedrock investigations, LFGPR can be used for tunnel detection and deep utility surveys.
