How We Got Started

While dewatering for utility contractors, whose jobs spread over long lines, Tri-State developed a very mobile operation. There were two pieces of equipment that helped to change the Tri-State business focus --  the Watson truck-mounted drill rig and the Barco boom truck. This equipment made it possible for crews to move to a new location and set up, ready to drill, faster than ever before. This new capability launched Tri-State's move into the power line construction industry.
