Dredging: Initial dredging to remove approximately 1M CY of silt and sand(shoaled) material from the Houston Ship Channel (HSC) with placement intocontained placement areas. Follow up dredging to mine new work clay fromthe bottom of the HSC for use in construction of approximately 22,000 linearfeet of new levee in Galveston Bay.Weeks Marine’s expertise is gained from similar projects involving theutilization of a spill barge for initial placement of hydraulically excavateddredge materials into new levee construction. 30” diameter dredge pipe isplaced along the bottom of the Bay to reach the spill barge location wheredredged material is placed along the engineered alignment utilizing GPSpositioning equipment. Following initial placement, WMI’s clamshell groupperformed final shaping and grading of the levee in preparation for installationof 250,000 Tons of stone shore protection.
