The purpose of the work specified herein is to determine the type, nature, characteristics, depth, and extent of the subsurface materi als as they exist at the locations specified. This is to be accomplished by drilling at twenty-two (22) sites utilizing a drill rig that has a dual capacity, for example, the drill rig shall be able to drill through overburden using hollow stem augers and shall then be able to be transformed to use HQ drilling equipment to core the existing bedrock at each drill site. In addition, the work includes excavating five (5) dozer-trenches to a maximum depth of 30-feet using a D-10R, a Komatsu 455 or equivalent s ize dozer. Drill holes will range in depth from a minimum of 80 feet to a maximum of 150 feet. Locations of the borings and trenches will be determined in the field by a Government Representative from the Sacramento District, U.S. Army Corps of Engineers . Soil sampling from the trenching portion of this project will be conducted and samples will be placed in 55-gallon steel drums and in canvas sample bags. Also, soil samples will be collected from each drill site during overburden drilling using both SP T and 3-inch-diameter California Modified Samplers and an automatic trip hammer with 30-inches of free fall. These samples will be placed in plastic baggies provided by the Government. The Contractor will provide a driller and helper for each drill rig us ed during this project. The Contractor will also obtain the services of a qualified dozer operator and one helper for all dozer-trench excavations.
