Cheesman Dam Rock Stabilization

Harrison Western mitigated serious rockfall threats along the face of a downstream canyon wall adjacent to the Cheesman Dam. HW designed the rock bolt patterns, installed and tensioned the rock bolts, and installed a perforated drain line with a shotcrete cover. Due to the location and geographic challenges, drilling work was performed via a drill basket suspended by crane, and rope work was conducted by SPRAT-certified personnel.
