structure. <br /> Rubble generated through the demolition process shall be disposed <br /> of at the Central Work Area disposal site, which is located <br /> immediately south of the demolition corridor. The perimeter of the <br /> disposal area shall be marked in the field by PROJECT MANAGER. <br /> The rubble generated as a result of the demolition process, <br /> including all other rubble, trash and debris, shall be placed <br /> against the back wall of the disposal area, and shall be evenly <br /> spread at the base of the feature for the length of the disposal <br /> area. The rubble shall be placed as tightly as possible within the <br /> disposal area. The height of the rubble, upon completion of the <br /> disposal process, shall not exceed twenty feet (201 ) as measured <br /> from ground surface at the southern most extent of the disposal <br /> area. The disposal area shall be constructed so that upon <br /> completion, the side slopes of the rubble do not exceed 5H:1V on <br /> the north slope, 4H: 1V on the east slope and 3H:1V on the west <br /> slope. Rubble shall be deposited in the disposal area in such a <br /> manner so that void spaces are minimized, and so that the top of <br /> the rubble is level . No piece of rubble or debris may exceed a <br /> height of eighteen inches (1811 ) above the mean elevation of the <br /> surrounding material . <br /> Materials targeted for demolition which lie within the footprint of <br /> the disposal area do not need to be demolished unless any such <br /> material, structure foundation or pad exceeds the height of the <br /> rubble which surrounds it upon completion of Task 2, Demolition. <br /> East Work Area <br /> All concrete, block wall, and asphaltic materials as well as <br /> miscellaneous debris and materials located within the designated <br /> demolition area will be demolished and transported to the Central <br /> Work Area disposal site. At least three significant buildings had <br /> been located within this work area. A footer which is not <br /> associated with a mapped building has been observed at the eastern <br /> portion of the work area. Asphalt has been observed in many <br /> portions of the work area. All structures, foundations, pads and <br /> footers shall be excavated to a depth of three feet (31 ) below <br /> ground level as measured from ground surface immediately adjacent <br /> to each structure. <br /> Rubble generated as a result of the demolition in the East Work <br /> Area shall be transported to the Central Work Area for disposal. <br /> Disposal of the rubble from this work area shall conform to the <br /> disposal area construction requirements described in the Central <br /> Work Area description, above. <br /> Measurement and Payment <br /> There will be no measurement for payment. Payment for this task <br /> 4 <br />
