BATH IRON WORKS LAND LEVEL TRANSFER FACILITY DREDGING

Dredging Activities

Bath, Maine - EnviroTech provided third-party data documenting dredging activities in lieu of pending litigation. Dredging was required to allow construction of caissons, cofferdam cells and precast piles at required elevations for the facility's Land Level Transfer Facility. Services included documenting river bottom elevations before and after dredging while compensating for tidal influences on elevations. Work was done within a grid system and, therefore required use of survey equipment to locate dredging equipment and document dredged locations. Complied tables, field notes and figures documenting dredging activities that were later used in litigation.
