bluegrass participated in the saluda dam remediation project in south carolina, a requirement by the federal energy regulatory commission which involved seismic upgrades to the dam and building a backup dam immediately downstream. bluegrass was contracted to assist with removal of concrete piers and retaining wall to provide access to the penstock towers which supply water to the turbines in the hydroelectric plant. bluegrass diamond wire saws were ideally suited to the job because of the minimal vibration emitted, therefore avoided the potential hazard of vibrating debris into the draft tubes. expansive grout and robotic hammers were also used to break the concrete blocks for removal.
