BGC’s specialized understanding of the application of geologic sciences to engineering practice is one of our core competencies. We are experts at assuring that the geologic factors affecting the location, design, construction, operation and maintenance of engineering works are recognized and adequately provided for.
We provide superior engineering geology services related to the following aspects:
Terrain analysis includes examination of aerial photographs, satellite imagery and LiDAR (Light Detection and Ranging), in conjunction with field observations, published maps and other datasets to delineate terrain into polygons with uniform geotechnical characteristics. BGC uses terrain analysis to develop landslide inventories, characterize fluvial and other geomorphic processes, support project siting and routing studies, and identify targets for subsurface geotechnical investigation.
Bedrock structure can have an overriding influence on many geotechnical parameters, including rippability, hydraulic conductivity, bearing capacity, and the stability of natural and man-made slopes. We combine our knowledge of bedrock geology and tectonic history with field mapping, geotechnical drilling, and remote sensing techniques including LiDAR and photogrammetry to develop structural geology models for our project sites
BGC employs a wide range of techniques for geotechnical characterization, including air photo interpretation, surface mapping, geophysical surveys, test pitting, geotechnical drilling, instrumentation, and laboratory testing. Our geotechnical site investigation programs begin with the development of a conceptual engineering geology model that is refined throughout the development of a project.
Using our specialized knowledge of hydrology and hydrogeology, BGC helps our clients understand how water impacts their projects and infrastructure from a geomorphological perspective. We integrate our water resources expertise with our comprehensive range of engineering geology services for a wide variety of industries, including mining, oil sands, pipelines, transportation and the public sector. We are well-versed in in-situ and laboratory testing methods, groundwater monitoring and sampling, and two and three-dimensional groundwater modeling techniques.
Building on our terrain analysis and geotechnical site characterization, we extend our understanding of the potential for geohazards to affect project sites and infrastructure through methods such as seismic hazard assessment, liquefaction susceptibility modeling, field mapping of landslide deposits, dendrochronology, radiocarbon dating, slope stability assessment, and landslide runout modeling. In addition to geohazard identification, we have expertise in the related aspects of hazard and risk assessment, along with selection of appropriate mitigation measures. Our engineers use this information to prepare mitigation designs for suggested measures, keeping the entire process in-house.
