Mike Haggerty has nearly 15 years of experience specializing in geotechnical issues associated with tunnels and open-pit mines. His projects often involve inspection and rehabilitation of existing tunnel infrastructure and design of underground space.

Mike has also performed annual dam safety inspections on large embankment tailings dams and modeling for dam seepage, stability, and deformation analysis using GeoStudio software. He has served as on-site field engineer and geologist for numerous projects and directed drill crews for hollow-stem-auger, air-rotary, sonic, duel-casing, rock coring, and cone penetration test (CPT) investigations.
