TASK 1 MOBILIZATION AND DEMOBILIZATION This task shall comply with specification 1.0, Mobilization/Demobilization, attached. Measurement and Payment There will be no measurement for payment. Payment for this task will be reflected in a lump sum bid under Item 1 on the Bid Schedule. This lump sum bid will cover all costs for Mobilization and Demobilization. Payment shall be made as described in specification 1.0, Mobilization/Demobilization, attached. TASK 2 EARTH WORK CONTRACTOR, in conjunction with PROJECT MANAGER will stake the boundaries of the area of the Old Refuse Pile to be affected by this project. This will occur prior to initiating any work within the Project area. The earth work portion of this project consists of reducing the north slope of the Old Refuse Pile to the design specification of 2H:1V. Material excavated from the Pile will be transported to the designated disposal site. Map 4, Old Refuse Pile, depicts the current topography of the facility, locations of Cross Sections A through H and outlines the portion of the facility which is subject to this Project. Map 3, Project Area, depicts the location where the excavated materials will be placed, and the location of the topsoil stock pile from which the topsoil will be derived. Map 5, Reclaimed Topography, depicts the post construction contours of the Old Refuse Pile, and the locations of Cross Sections AR through HR. Map 6, Disposal Area Topography, depicts the idealized contours of the disposal area near the former location of the Wash Plant upon completion of the Project.. In its present condition, the slopes subject to this project vary in gradient from slightly steeper than 1.5H:1V to just less than 2H:1V, with the majority of the slope averaging about 1.75H : 1V. Cross Sections A through H depict the current topography. Upon completion of the project, the gradient of the north slope of the Old Refuse Pile will average 2H:1V. The gradient at any one location may vary between 1.9H:1V and 2.1H:1V, as depicted on Cross Sections AR through HR. A variance in slope gradient which results in any one cross sectional slope being steeper than 1.9H:1V is not permitted. An existing roadway located near the top of the slope to be cut must be maintained throughout the project at a minimum width of twelve feet (12') . North Slope Old Refuse Pile Cut and Fill In some portions of the project area topsoil has been spread over slopes which are at a gradient of 2H:1V. The soil in these less steep locations will be salvaged by CONTRACTOR, and stockpiled at the location noted on Map 3, Project Area. It is estimated that cubic yards of coal refuse material will be excavated from the Old Refuse Pile in order to achieve the specified 2H:1V post construction slope. Of this volume, 13
