120-11 Construction. <br />120-11.1 Construction Tolerances: Shape the surface of the earthwork to conform <br />to the lines, grades, and cross-sections shown in the plans. In final shaping of the surface <br />of earthwork, maintain a tolerance of 0.3 foot above or below the plan cross-section with <br />the following exceptions: <br />1. Shape the surface of shoulders to within 0.1 foot of the plan cross-section. <br />2. Shape the earthwork to match adjacent pavement, curb, sidewalk, <br />structures, etc. <br />3. Shape the bottom of ditches so that the ditch impounds no water. <br />4. When the work does not include construction of base or pavement, shape <br />the. entire roadbed (shoulder point to shoulder point) to within 0.1 foot above or below the <br />plan cross-section. <br />Ensure that the shoulder lines do not vary horizontally more than 0.3 foot from <br />the'true lines shown in the plans. <br />120-11.2 Operations Adjacent to Pavement: Carefully dress areas adjacent to <br />pavement areas to avoid damage to such pavement. Complete grassing of shoulder areas <br />prior to placing the final wearing course. Do not manipulate any embankment material on a <br />pavement surface. <br />When shoulder dressing is underway adjacent to a pavement lane being used <br />to maintain traffic, exercise extreme care to avoid interference with the safe movement of <br />traffic. <br />120-12 Method of Measurement. <br />120-12.1 Excavation: Excavation will be paid for by volume, in cubic yards, <br />calculated by the method of average end areas, unless the Engineer determines that <br />another method of calculation will provide a more accurate result. The material will be <br />measured in its original position by field survey or by photogrammetric means as <br />designated by the Engineer. Measurement for payment will include the excavation of <br />unsuitable material, lateral ditch excavation, channel excavation, and excavation for <br />structures and pipe. Payment will not be made for excavation or embankment beyond the <br />limits shown in the plans or authorized by the Engineer. <br />120-12.2 Embankment: Measurement will be made on a loose volume basis, as <br />measured in trucks or other hauling equipment at the point of dumping on the road. <br />Payment will not be made for embankment beyond the limits shown in the plans or <br />authorized by the Engineer. <br />120-13 Basis of Payment. <br />120-13.1 General: Prices and payments for the work items included in this Section <br />will be full compensation for all work described herein, including excavating, dredging, <br />hauling, placing, and compacting; dressing the surface of the earthwork; and maintaining <br />and protecting the complete earthwork. <br />120-13.2 Excavation: The total quantity of all excavation specified under this <br />Section will be paid for at the Contract unit price for Excavation. No payment will be made <br />for the excavation of any materials which are used for purposes other than those shown in <br />the plans or designated by the Engineer. No payment will be made for materials excavated <br />outside the lines and grades given by the Engineer, unless specifically authorized by the <br />Engineer. <br />120-13.3 Embankment: The total quantity of embankment specified in this Section <br />will be paid for at the Contract unit price for embankment. No payment will be made for <br />01025-25 Technical Specifications <br />F:\Public Works\ENGINEERING DIVISION PROJECTS\1503-43rd Ave Swk_Airport Dr to 41st St\1-Admin\Bids\Bid <br />Documents\Master Contract Documents\Technical Specifications.doc <br />
