RAYMOND W.
HENN
Principal
Summary of
Experience
Mr. Henn has more than 36 years of heavy and
underground construction experience with a concentration in shafts and tunneling,
water and wastewater, transportation and hydroelectric projects. During his career, Mr. 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
$900M. 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. Mr. Henn's tunneling
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 with cast-in-place and precast
concrete, shotcrete, and 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.
Mr. Henn is currently a Principal at Lyman Henn,
Inc. Mr. Henn is responsible for tunnel
and underground engineering, and construction management services. He also provides construction consulting
services in areas of construction methods and equipment evaluation, cost and
scheduling, value engineering, constructability and claims avoidance reviews,
performing claim evaluations and negotiations, and litigation support. He has also conducted tunnel condition surveys. Additionally, Mr. Henn has served on 18
Dispute Review Boards and as an Arbitrator on construction cases. Mr. Henn is past President of the American
Underground Construction Association and recipient of the ASCE’s 2002 Roebling
Award in Construction Engineering.
