TASK 1 MOBILIZATION AND DEMOBILIZATION <br />Measurement and Payment <br />TASK 2 DEMOLITION <br />This task shall comply with specification 1.0, Mobilization/Demobilization, attached. The cost of <br />Mobilization and demobilization shall include such items as providing security to ensure <br />pedestrian and vehicular traffic are well away from the work area should any foundations be <br />blasted, obtaining appropriate insurance for blasting, should any be done, locking of the mine gate <br />during the life of the project, and maintenance of a hazard -free work place. <br />There will be no measurement for payment. Payment for this task will be reflected in a lump sum <br />bid under Item 1 on the Bid Schedule. This lump sum bid will cover all costs for Mobilization and <br />Demobilization. Payment shall be made as described in specification 1.0, <br />Mobilization/Demobilization, attached. <br />NOTE: Task 2 was replaced by amendment Number 1 (October 7, 1997). The amended <br />Task 2, Demolition, is included here. <br />For purposes of the demolition task, all concrete structures located within the area depicted on <br />Map 3, project area, are subject to the requirements of this task, unless otherwise specified. <br />There are two overall objectives of the demolition task. The first is to demolish designated <br />concrete and block wall building remnants and foundations, as well as conveyor foundations, <br />asphaltic pads and similar materials which are located within the work areas. The second <br />objective is to remove the rubble produced by the demolition process to designated disposal sites. <br />The Mid - Continent Resources Mining Permit application estimates that 50,000 cubic yards of <br />concrete and block wall materials are present within the project area. Note, however, that this <br />figure is an estimation only. and that only a portion of the materials within the project area will be <br />demolished. Contractors are encouraged to perform independent verification measurements in <br />order to ascertain the true volume of materials within the project area. Past demolition <br />experience at Coal Basin indicates that substantial quantities of rebar are present within most <br />concrete structures. <br />The project area encompasses the former location of a wash plant, thermal drier facility, offices, <br />parking areas, incidental buildings, conveyor belt route, and various other structures. All concrete <br />materials, asphaltic material and block wall materials located within the project area, outside of <br />the designated disposal areas, must be demolished and disposed of. Demolition must be <br />accomplished to a depth of at least three feet (3') below ground surface, as measured immediately <br />6 <br />
