Installing a large diameter intake pipe while maintaining minimal disturbance to surrounding railroads, businesses and vehicular traffic.
Ballast Nedham decided to drive the host pipe with a modified IHC S-90 offshore hammer. They used Permalok® 120” O. D. Casing to complete the task. The size of the pipe, along with the lengths of the drives, made this project the largest horizontal driving job ever completed. In 2002, Trenchless Technology recognized the project as an Honorable Mention in Project of The Year Competition for New Installation.
