The rebuilt equipment features state-of-the-art guidance and operations systems, as well as data logging equipment. “The technology has advanced to the point where we needed to bring our old equipment up to date,” said Paul Vadnais. “The new controls and drives make the machines much more reliable.”
The refurbished machines include a 67-in. Sotau that Vadnais purchased used in 1995, and a 60-in. Soltau purchased in 1996 that was Vadnais’ first ever new microtunneling system purchased. That was refurbished first and has gone on to complete a 421-ft crossing project in Amarillo, Texas.
