About this file
This is a Technical Specifications and Special Conditions document prepared by the Commonwealth of Virginia Department of Energy, Division of Mineral Mining, for mine site reclamation work at the DWH, LLC P.N. 90505AA Bond Forfeiture location in Virginia Beach, Virginia. The project encompasses several key work items including mobilization and demobilization, site preparation, removal and disposal of two large piles of tree debris, removal of structures (one Conex box storage trailer and signage), special lime treatment for acidic soil areas totaling approximately 2.37 acres, revegetation of all disturbed areas, and final cleanup and repair of any damage. The work must be completed within 45 calendar days from contract award. The contractor is responsible for furnishing all labor, supervision, materials, tools, and equipment necessary to perform the work and must maintain compliance with all applicable federal, state, and local environmental, safety, and permitting requirements throughout project execution.
The specification establishes a lump sum bidding structure for most work items, with mobilization costs capped at 10 percent of the base bid amount, and revegetation measured and paid on a per-acre basis. The contractor must obtain all necessary permits and approvals for operations such as tree burning, coordinate with the Army Corps of Engineers regarding any applicable permits, contact Miss Utility to locate underground utilities, implement erosion and sediment control measures, and comply with Department of Environmental Quality regulations. The contractor bears full responsibility for disposal fees, permitting costs, and any method-of-disposal-related expenses. The Agency will provide the site in an "as is" condition, furnish design and detail drawings, and conduct inspections throughout construction. The contractor must maintain all seeded areas until final project acceptance and is responsible for restoring or replacing any defective work at no additional cost to the Agency.
