5. Confirm that your firm possesses the capability to perform dredging operations on the McClellan-Kerr Arkansas River Navigation System (MKARNS) in accordance with the following specifications. Provide name of dredge, dimensions, and operating parameters (suction diameter, discharge diameter, etc.); and briefly discuss your firm’s dredging experience and past performance. You may provide additional sheets and/or capability statements.

a. The Contractor shall furnish and use a cutter-head dredge complete with attendant plant for performance of maintenance dredging in designated areas located between Navigation Miles 0 and 444.8 on the McClellan-Kerr Arkansas River Navigation System.

b. The Contractor shall be able to move the dredge and attendant plant to work locations in river flows up to 150,000 cfs on the Arkansas River portion of the navigation system, N.M. 19.0 to N.M. 395.0, in river flows up to 25,000 cfs on the Verdigris River portion of the navigation system, N.M. 395.0 to N.M. 444.8, and in current velocities of 10 feet per second on the White River portion of the navigation system, N.M. 0.0 to N.M. 9.8.

c. Each dredge shall be capable of the minimum output shown below per 24-hour day (21 hours pumping time) for the pipeline lengths and lifts shown:

The dredge shall be proportioned to make a dredging cut of 150 feet minimum width at a depth of 12 feet below navigation pool in a single pass. The dredging ladder and spuds shall be of sufficient length and construction that the dredge will dig efficiently in material to a depth of 30 feet below the water surface and in current flows ranging from zero to 6 feet per second. The ladders and spuds shall be of such construction as to allow the dredge to work effectively in 9 feet of water without dragging the ladder. The Contractor shall have available for use at all times a variety of interchangeable pump impellers to permit the dredge to work under varying conditions of length of discharge line and lift. The draft of the dredge shall not exceed 9 feet.

(A station of dredging is equivalent to 100 feet of advance by the dredge in a cut that averages 150 feet in width at the base of the cut and averages 3 feet of depth)
