120-11 Construction. 120-11.1 Construction Tolerances: Shape the surface of the earthwork to conform to the lines, grades, and cross-sections shown in the plans. In final shaping of the surface of earthwork, maintain a tolerance of 0.3 foot above or below the plan cross-section with the following exceptions: 1. Shape the surface of shoulders to within 0.1 foot of the plan cross-section. 2. Shape the earthwork to match adjacent pavement, curb, sidewalk, structures, etc. 3. Shape the bottom of ditches so that the ditch impounds no water. i 4. When the work does not include construction of base or pavement, shape the entire roadbed (shoulder point to shoulder point)to within 0.1 foot above or below the plan cross-section. Ensure that the shoulder lines do not vary horizontally more than 0.3 foot from the true lines shown in the plans. 120-11.2 Operations Adjacent to Pavement: Carefully dress areas adjacent to j pavement areas to avoid damage to such pavement. Complete grassing of shoulder areas I prior to placing the final wearing course. Do not manipulate any embankment material on a pavement surface. When shoulder dressing is underway adjacent to a pavement lane being used to maintain traffic, exercise extreme care to avoid interference with the safe movement of traffic. i 120-12 Method of Measurement. 120-12.1 Excavation: Excavation will be paid for by volume, in cubic yards, calculated by the method of average end areas, unless the Engineer determines that another method of calculation will provide a more accurate result. The material will be measured in its original position by field survey or by photogrammetric means as designated by the Engineer. Measurement for payment will include the excavation of unsuitable material, lateral ditch ` excavation, channel excavation, and excavation for structures and pipe. Payment will not be made for excavation or embankment beyond the limits shown in the plans or authorized by the Engineer. 120-12.2 Embankment: Measurement will be made on a loose volume basis, as measured in trucks or other hauling equipment at the point of dumping on the road. Payment will not be made for embankment beyond the limits shown in the plans or authorized by the j Engineer. 120-13]Basis of Payment. 120-13.1 General: Prices and payments for the work items included in this Section will be full compensation for all work described herein, including excavating, dredging, hauling, placing, and compacting; dressing the surface of the earthwork; and maintaining and protecting the complete earthwork. 120-13.2 Excavation: The total quantity of all excavation specified under this Section will be paid for at the Contract unit price for Excavation. No payment will be made for the excavation of any materials which are used for purposes other than those shown in the plans or designated by the Engineer. No payment will be made for materials excavated outside the lines and grades given by the Engineer, unless specifically authorized by the Engineer. 120-13.3 Embankment:The total quantity of embankment specified in this Section will be paid for at the Contract unit price for embankment. No payment will be made for materials which are used for purposes other than those shown in the plans or designated by the 01025-33 Technical Specifications F:\Public Works\ENGINEERING DIVISION PROJECTS\1123 43rd Ave Sidewalk Improvements 26th St.to Airport Dr West\Admim\bid documents\Master Contract Documents\Technical Specifications.doc
