Pipe Ramming Projects Pipe ramming is a non-steerable method of forming a bore by driving a steel casing, usually open-ended, horizontally through the ground with a percussive hammer. The soil may be removed from an open-ended casing by augering, jetting or compressed air. In appropriate ground conditions, a closed casing may be used. Since the material is not excavated until after the pipe has been driven into place, there is little or no settlement of the surface roadway or railbed.     Project   Contractor Tampa Bay Water Project   Ballast Nedham El Dorado RR Crossing Project   Middlecreek Mining IDOT RR Crossing Project   Miller the Driller Gold Beach, Oregon   Freeman Rock Enterprises/SCCI The Highway 238-to-Jackson Street Project   Northwest Boring Company, Inc.
