Lean, Innovative and Unique Project Solutions

To reduce equipment costs and eliminate particular safety hazards pertaining to the use of electrical cords, Cianbro used battery-powered magnetic drills to drill out the transmission poles, either on the ground or after they were standing in the air, eliminating the use of generators and electrical cords.
