Professional Experience

Dr. Henn has more than 40 years of heavy and underground construction experience with a concentration in shafts and tunneling, hydroelectric, water and wastewater, and transportation projects. During his career, Dr. Henn has held positions from field engineer through superintendent to construction manager on both direct-hire construction, and construction management assignments. The projects have ranged in value from $2M to $1.2B. He has a strong background in general civil construction, mass and specialty concrete placement, deep foundations, shaft and tunnel excavation and lining, and marine construction. Dr. Henn's underground experience includes conventional drill and blast, tunnel boring machine, roadheader, and sequential excavation methods in hard rock, mixed-face, and soft-ground conditions. He has experience with deep shaft and large chamber excavations, as well as pressure tunnels. He has worked extensively with cast-in-place and precast concrete, shotcrete, and various types of pipe tunnel lining systems. His foundations background consists of mass excavations, geotechnical and structural grouting, sheet piling, construction dewatering, post tension anchors, rock bolting, soldier pile and lagging, structural slurry wall construction, drilled shafts, and soil nailing.
