The functions of the Geotechnical Engineering Section within the Construction & Materials Bureau are principally directed toward providing foundation recommendations for all structures. The Section has a team to conduct subsurface explorations and a geologist to analyze rock samples and administer the rock fall hazard mitigation plan. The Section provides slope stability analyses for the highway and rail network, and tests soil and aggregate samples in support of design and construction.
