Measurement and Payment <br /> There will be no measurement for payment. Payment for this task will be reflected in a lump sum <br /> bid under Item 2 on the Bid Schedule. This lump sum bid will cover all costs for debris collection, <br /> disposal, building removal, and concrete demolition and disposal. Payment shall be as this task <br /> is completed and approved by the PROJECT MANAGER. Such payment shall be considered full <br /> compensation for all labor, materials, equipment and all other items necessary and incidental to <br /> the completion of Task 2, Demolition. <br /> TASK 3 CULVERT REMOVAL <br /> Wash Plant Area <br /> Approximately seven (7) road drainage culverts are located on the roads in the vicinity of the <br /> Wash Plant and Sutey Refuse Pile. Project Manager will locate each culvert to be removed and <br /> place lathe and flagging at each prior to construction. Excepting the thirty six inch (36") diameter <br /> culvert located on the main Sutey access road near the confluence of Ditches 1 and 8, the <br /> culverts are generally eighteen to twenty four inches (18" to 24") in diameter. These culverts are <br /> constructed of corrugated metal°pipe (CMP) in almost all instances. Generally, road drainage <br /> culverts are buried by three feet (T) or less of ground cover at the inlet <br /> Culverts shall be excavated and removed from the site. All head walls, down drains or other <br /> structures associated with the culverts shall be removed during reclamation. The trenches which <br /> result from the extraction process shall be backfilled to the original ground surface elevation. <br /> The backfill will be mechanically compacted in one foot (1') lifts. However, the excavation of the <br /> large main Sutey access road culvert (36" culvert) by Ditches 1 and 8 does not need to be <br /> backfilled, as a low water crossing shall be constructed at this location (Task 6). <br /> Rock Tunnel Vicinity <br /> The Road E culvert is an approximately ten feet (10') diameter corrugated metal pipe culvert, <br /> located approximately 150 feet north of the Lamp House on the North Fork of Dutch Creek (Map <br /> 3, Project Area). The dirt overlying the culvert, and the dirt to be excavated from the sides of the <br /> culvert will be removed to the hillside adjacent to Road E, approximately seventy five feet (75') <br /> south of the culvert location. This material shall be placed and compacted against the hillside in <br /> horizontal lifts, to be compacted in two foot (2') intervals. The outslopes of the fill shall be no <br /> steeper than 2.5HA V. The north and south margins of the fill slope shall be graded so that they <br /> blend into the adjacent hill slopes <br /> The culvert shall be removed from the Project Area by CONTRACTOR, who may either keep the <br /> culvert, or properly dispose of it in a licensed disposal facility. <br /> Excavation and removal of the culvert shall be accomplished so that the gradient of the channel <br /> floor above and below the former location of the culvert match when this Task is completed. The <br /> slopes on the sides of the culvert shall be excavated to a configuration no steeper than 3H:1V. <br /> The excavated material and the cuts created during removal of the culvert will be roughened (see <br /> Task 9, Topsoil Application and Surface Roughening), and revegetated. The surfaces of the <br /> stream sides above the high water line shall be left in a roughened condition, and revegetated. <br /> These areas will not be topsoiled. <br /> 10 <br />
