TASK 2 DEMOLITION <br />For purposes of the demolition task, all concrete structures located within the area <br />depicted on Map 3, Project Area, are subject to the requirements of this task, unless <br />otherwise specified. <br />There are two overall objectives of the demolition task. The first is to demolish concrete <br />and block wall building remnants and foundations, conveyor foundations, asphaltic pads <br />and similar materials which are located within the work areas. The second objective is <br />to remove the rubble produced by the demolition process to designated disposal sites. <br />Past demolition experience at Coal Basin indicates that substantial quantities of rebar <br />are present within most concrete structures. <br />The Mid - Continent Resources Mining Permit Application estimates that 50,000 cubic <br />yards of concrete and block wall materials are present within the Project Area. Note, <br />however, that this figure is an estimation only. CONTRACTORS are encouraged to <br />perform independent verification measurements in order to ascertain the true volume of <br />materials within the Project Area. <br />The Project Area encompasses the former location of a wash plant, thermal drier facility, <br />offices, parking areas, incidental buildings, conveyor belt route, and various other <br />structures. Foundations, footers, floors, previously demolished debris and asphaltic <br />parking areas are the dominant structures in place. Most of the building remnants and <br />previously demolished debris are composed of reinforced concrete, or of cinder block <br />like materials. Much of the southeastern portion of the work area is covered by asphalt. <br />All building remnants, including concrete, asphaltic materials and block wall materials <br />located within the Project Area must be demolished and disposed of. Demolition must <br />be accomplished to a depth of at least four feet (4') below ground surface, as measured <br />immediately adjacent to any one structure. <br />Concrete foundations which supported the Sutey Refuse Disposal Area conveyor and <br />associated stacking equipment are located in the western portion of the Project Area, and <br />on the north side of Coal Creek. <br />In order to assure that all of the target materials are identified, demolished and disposed <br />of, the Project Area will be ripped by dozer to a depth of at least three feet (3'). <br />Subsurface structures identified during the ripping of the site shall be demolished and <br />disposed of as described above. Failure to describe specific concrete or block wall <br />structures does not negate the requirement to complete demolition as per these <br />specifications.
