Summary of Specifications:
The work involves regular dredging in Cells 3 and 4, and possibly in other cells as directed by the County, transfer of dredged sludge to the sludge holding ponds, and transferring from the holding ponds into trucks for transport. The Contractor shall typically perform sludge dredging and the filling operation between the hours of 7 a.m. and 4 p.m. (CST), Monday through Friday. The Contractor may, on some occasions, operate on weekends or holidays as necessary to maintain sludge removal with prior approval from the County. The Contractor shall provide all equipment and piping necessary to dredge, pump to the holding ponds, dewater, and fill the trucks for sludge transport from the Military Point Lagoon. All equipment shall be kept in good repair and all sludge is to be contained properly. Contractor is responsible for any clean up costs for spilled material. A permanent transfer pipe penetrates the berm for transferring sludge from the dredge operation. Decanting and drying in the holding ponds thickens the sludge to an approximate solids content of 6% to 12%. The average sludge solids content was approximately 8%. The volume of dredged material is estimated not to exceed 75,000 cubic yards. Transport of thickened sludge, performed by another contractor, to a disposal site is estimated to be approximately 2,000 dry tons per year during the entire term of the contract. Due to the nature of the process and variability of the material, the County does not guarantee the amount of sludge the successful bidder will remove.
