AUS had multiple dive teams working on the Nine Mile Dam project. The underwater work is part of a large refurbishment project for Avista corporation. AUS performed underwater operations including wall sawing, core drilling, welding, burning, anchor bolt installation, steel setting, grouting, bulkhead guides, and bulkhead installation and removal. The challenging working conditions required a team effort and an acute awareness for safety to accomplish the tasks at hand. AUS also had a dive team on Post Falls Dam, just upstream from Nine Mile Dam, where the team performed dam rehabilitation work.
