The proposed maintenance dredging would remove approximately 75,000 cubic yards of sediment (approx. 25,000 cubic yards as basic work, and the remaining as options). Dredging in the basic work area will be required to a depth of 40 feet below Mean Lower Low Water (MLLW) with 1 foot allowable over-depth. Dredging in the option work area will be required to a depth of 35 feet below Mean Lower Low Water (MLLW) with 1 foot allowable over-depth. Due to restrictions found in the water quality certificate, the proposed work must/can only be performed by a large mechanical dredge with a closed environmental clamshell bucket. Additionally, multiple barges and tug boats will be needed to perform the work during the dredging, dewatering and unloading operations. There are several options to the contract. The options, if they are exercised, may not be exercised in numerical order. If the options are exercised, their performance periods will be consecutive. The time for contract completion of each option will be determined by allowing a rate of one calendar day for each 2,250 cubic yards removed. The contractor is required to maintain an integrated production of at least 2,250 cubic yards per calendar day. The work is estimated to cost between USD6 – USD8 million (basic and options). Plans/Specs for the subject project would be available on/about February 22, 2011 with bid opening on/about March 24, 2011. It is the intention of the Government to award in May 2011 and issue the NTP on/about June 3, 2011.
