About this file
This file is an as-built plans and drawings exhibit for the West Virginia Army National Guard Camp Dawson located in Kingwood, West Virginia, specifically for the Pringle Training Site West Pond Sediment Remediation project. The document provides detailed construction specifications and requirements for demolition, grading, drainage, and erosion control operations at the site. Key project requirements include stripping and redistributing topsoil to a minimum depth of six inches across cut and fill areas, mulching and seeding all graded areas within 15 days of completion, constructing temporary erosion control measures prior to grading operations, and removing sediment from all drainage structures and detention ponds before final acceptance. The contractor must obtain all required permits, locate and mark existing utilities prior to commencing work, and coordinate with local utility companies for disconnections. All storm drainage pipe shall be 12-gauge Type II aluminized corrugated metal pipe, cut and fill slopes shall not exceed 3:1 gradient, and earthwork fill must be placed in maximum eight-inch compacted lifts at 98 percent density per ASTM D698 standards. An as-built set of plans must be submitted to the West Virginia Department of Environmental Protection upon completion of sedimentation basin construction.
The project is subject to West Virginia Department of Environmental Protection's General NPDES Permit requirements for storm water discharge associated with construction activity, as the work disturbs more than five acres. The contractor bears responsibility for all contractor-caused damage repairs at no additional cost to the owner, proper disposal of demolished materials in a legal manner, and removal of temporary erosion control devices when no longer required. Finish grade tolerances are established at 0.10 foot above or below design elevations, and the contractor must verify existing elevations and inverts prior to beginning work. Excess material must be disposed of on the owner's property at no additional cost in a legal manner. The document was prepared by a West Virginia registered engineer and dated June 8, 2010.
