The Contractor shall be responsible for damages caused by excessive dredging. The side slope allowances are described in the previous paragraph. The Average Required Bottom Depth is not greater than one (1.0) foot therefore the Contractor does not incur the Excessive Depth Penalty. The Average Required Bottom Depth is ((7.5+6.5)/2)=7.0 MLW subtract 6.0 MLW = 1.0 feet. Example (2) – Assume all of the variables are the same as in Example (1) except Channel 3A Station 2+00 is dredged to 7.5 MLW.

The Contractor will incur the Excessive Depth Penalty equal to the ((average of the Station depths, ((8.5+6.5)/2)=7.5 minus the Required Bottom Depth,6.0) multiplied by the width of the Channel, 36 feet multiplied by the length between the Stations, 100 feet) divided by 27) multiplied by $5.00. Example (1) - If the Required Bottom Depth is 6.0 feet below mean low water (MLW) and the Contractor dredges to 8.5 feet MLW at Channel 3A Station 2+00 and 6.5 feet MLW at Channel 3A Station 2+50 the average depth between the Stations is 7.5 MLW. ANY MATERIAL REMOVED IN EXCESS OF ONE (1.0) FOOT BELOW THE AVERAGE REQUIRED BOTTOM DEPTH SHALL INCUR AN “EXCESSIVE DEPTH PENALTY” OF FIVE DOLLARS ($5.00) PER CUBIC YARD, which shall be deducted from Contractor payments. The Average Required Bottom Depth shall be calculated by averaging two adjacent 50 feet Station depths. Any material removed below the Average Required Bottom Depth will not be measured for payment. Excessive Dredging. Excessive dredging is defined to be any dredging which is in excess of the Required Bottom Depth, as shown on the contract drawings and listed in Appendix A, Acceptance Reach and Dredge Required Bottom Depth.
