Scott Shellabarger manages this division.  Our company has 25 to 35 pieces of equipment to service most excavation needs.  Excavators range in size from the small rubber-tired backhoe loaders to 95,000-pound excavators.  In addition to these machines, we have a compliment of rubber-tired loaders, bulldozers, compaction equipment and OSHA shoring boxes.  Rock excavation is a necessary part of most underground construction activities in this area.  We have a Furwakawa RC 180 hydraulic rock drill, and we do our own blasting.
