present within the Project Area. Note, however, that this figure is an estimation only, and that only a portion of the materials within the Project Area will be demolished. CONTRACTORS are encouraged to perform independent verification measurements in order to ascertain the true volume of materials within the Project Area. Past demolition experience at Coal Basin indicates that substantial quantities of rebar are present within most concrete structures. The Project Area encompasses the former location of a wash plant, thermal drier facility, offices, parking areas, incidental buildings, conveyor belt route, and various other structures. All concrete materials, asphaltic materials and block wall materials located within the Project Area, outside of the designated disposal areas, must be demolished and disposed of. Demolition must be accomplished to a depth of at least three feet (3') below ground surface, as measured immediately adjacent to any one structure. Some foundations and structures may not be visible at ground surface. Except as otherwise described in this Invitation and Bid, all rubble and assorted debris, including metallic materials, miscellaneous trash, debris and scrap encountered in the project area will be removed and placed with the building rubble at the designated disposal areas so that no rubble or debris remain at the work areas except at the disposal areas. Scrap wood materials shall be segregated from other debris and stockpiled in a location designated by PROJECT MANAGER. In order to assure that all of the target materials are identified, the Project Area will be ripped by dozer during performance of the Project. Ripping shall occur to a depth of eighteen inches (18 "), minimum. Subsurface structures, including asphalt and concrete debris and rubble identified during the ripping of the site shall be demolished and disposed of as per the enclosed specifications. Foundations, footers and similar reinforced materials may be demolished and disposed of per Task 5, Additional Demolition. Failure to describe specific concrete, asphalt or block wall structures in this Invitation and Bid does not negate the requirement to complete demolition as per these specifications. A map taken from the Mid - Continent Resources Permit Application is attached to this Invitation and Bid. This map depicts the locations of the structures which were located within the Project Area, as represented by Mid - Continent Resources to the Division of Minerals and Geology. The map may not thoroughly describe all structures which have been constructed within the Project Area, nor does it depict asphalt pads and roads. Certain concrete structures will not be removed during performance of this Project. These structures are the wing walls associated with the two large culverted crossings of Coal Creek, the concrete 2
