The project “Remedial Action for Lower Maumee River Sway Bridge within the Maumee Area of Concern” project is funded through a US Environmental Protection Agency grant. The work includes mobilization and site support services; implementation of erosion, turbidity, and sediment resuspension controls; and installation and monitoring of specialized instrumentation to protect existing structures during construction. The Contractor will perform mechanical dredging, transportation, and disposal of approximately 124,000 cubic yards of contaminated sediment and embedded debris. Dredged materials will be disposed of at the Toledo-Lucas County Port Authority (TLCPA) Confined Disposal Facility (CDF) and an approved commercial landfill, as applicable. The Work also includes hydraulic offloading, water management, and debris separation and disposal operations at the TLCPA CDF; removal and disposal of shipwrecks and other submerged debris; and installation of temporary steel sheet piling to support shoreline stability during dredging, followed by in situ abandonment of designated sheet piling. Bathymetric surveys and post-dredging verification sampling will be performed to document remedial performance. The Contractor will conduct residual dredging and place amended residual covers, as required, and will place engineered subaqueous backfill materials where necessary to restore slope stability. The Work concludes with demobilization and site restoration.

Description

The project involves mechanical dredging, transport, and disposal of approximately 124,000 cubic yards of contaminated sediment and embedded debris. Work includes erosion, turbidity, and sediment-resuspension controls; temporary steel sheet piling for shoreline stability; hydraulic offloading and water management; and removal and disposal of shipwrecks and other submerged debris. Dredged material will go to a confined disposal facility and, as applicable, an approved commercial landfill. The contractor will also conduct bathymetric surveys and post-dredging verification sampling, perform residual dredging and place amended residual covers as needed, and place engineered subaqueous backfill where necessary to restore slope stability. Optional work, if directed, may include organoclay placement, structural inspection diving, sheen mitigation, confined disposal facility drawdown, and additional sediment and debris removal. The estimated total for the base bid and approved optional work is approximately $22,612,100.
