This project involves work at up to 40 sites within the Malmstrom AFB Missile Field (10th, 12th, and 490th Missile Squadrons), located within a 140-mile radius of Great Falls, MT. The work includes directional boring to place 4" or 6" conduit at least 5 feet below creek or riverbanks, and erosion repair such as riprap placement, filling, and installing drainage features. The Government will attempt to group sites close together to minimize mobilization. The Contractor must provide all plant, labor, equipment, supervision, services, and materials to meet contract requirements. Detailed scope will be provided in the Statement of Work.
