Harrison Western installed rock anchors at Seven Falls for a new zipline adventure course. The anchor locations required rope access for HW crews on 400′-foot cliff faces and the use of temporary access ziplines for personnel, equipment, and materials. A private helicopter was also required to transport materials and equipment to some areas. Holes were drilled with hand drills and anchored with both resin and cement grout, depending on rock conditions. As part of the project, HW load tested and replaced anchors that had been previously installed by another contractor as necessary.
