New Global Hawk Aircraft Hanger

Youngdahl Consulting Group, Inc. has provided monitoring of the earthwork grading operations, including consultation, observation, testing services and special inspection, for several locations throughout Beale Air Force Base since 1994.

Notable projects include the construction of new approach lighting along the taxiway, and most recently the completion of earthwork and special inspection services for the Global Hawk Hangar.

Special inspections for the Global Hawk project included structural steel field welding observations at the second level deck and bridge crane.  We also performed special inspections for concrete and structural steel placement, masonry for interior and exterior walls, and soils and asphalt related testing.  Our inspection services included:
