Z -- HYANNIS HARBOR (PHASE II) MAINTENANCE AND IMPROVEMENT DREDGING, 13-FOOT CHANNEL AND BASIN SOL DACW33-98-B-0011 DUE 063098 POC Carol Husselbee, 978-318-8420 E-MAIL: Procurement Technician, Carol.K.Huseelbee@usace.army.mil. The work of this project consists primarily of 304,600 cubic yards of hydraulic and 60,800 cubic yards of mechanical dredging in Hyannis Harbor, with local disposal both on and offshore. Hydraulic dredging work involves the excavation of a Confined Aquatic Disposal Cell (CAD Cell) in Hyannis Harbor near the new outer channel, and maintenance dredging of specific reaches of the Federal Channel. Material hydraulically excavated from the CAD Cell shall be disposed of on shore at Dunbar Point. Material hydraulically excavated from the Federal Channel shall be disposed of as a cap for the CAD Cell, on Veterans Memorial Beach, and on the Lewis Bay Beaches at Hyannis Park in West Yarmouth. Shaping and grading of the excavated material is required only at Dunbar Point. Material deposited on the beaches will be shaped and graded by others. Mechanical dredging work involves the excavation of parts of the inner harbor, one reach of the Federal Channel, and the municipal channel and berths. Disposal of all mechanically excavated material shall be in the CAD Cell previously excavated by hydraulic methods. Additional work involves the overland hauling and placing of 22,000 cubic yards of previously deposited dredged material from Dunbar Point to Hyannis South Beach (shaping and grading of this dumped material will be performed by others), and the stabilization of dredged material placed at Dunbar Point through the planting of about 0.7 acres of American Beach grass. In all dredging areas, boulders and miscellaneous debris shall be removed as necessary to achieve project depth and width as shown on the contract drawings. The estimatd cost range is between $1,000,000.00 and $5,000,000.00. Work shall be completed within 75 calendar days after receipt of a Notice to Proceed. Plans and Specifications will be available on or about 05/27/98 at a cost of $22.00 per set. All responsible sources may submit a bid which will be considered by the New England District. (0119)
