Schnitzer Maintenance Dredging and Operations

Floyd|Snider provides engineering planning services for a bulk loading facility located on the Willamette River near Portland, Oregon. Work includes assessment of existing river berth conditions, identification of engineering constraints to vessel loading operations during periods of low water levels, and identification of conceptual redevelopment alternatives to improve future site operations and infrastructure.  Additional engineering services included completion of a maintenance dredging design and construction effort in 2008 which included completion of all permitting activities, development of a bid package including technical drawings and specifications, assisting the client in procurement of a dredging contractor, and management of the maintenance dredging activities. The project involved removal of approximately 10,000 cubic yards of sediment from within the Portland Harbor Superfund site and resulted in deepening the channel of the main bulk loading berth at the site. The maintenance dredging project was completed on-time and under budget. Floyd|Snider has also assisted Schnitzer Steel in waterfront site redevelopment planning in order to optimize future operations needs. Specific activities include coordinating with operations personnel to understand day to day site activities, evaluating engineering conditions of existing infrastructure, and incorporating redevelopment concepts and schedules into future remediation plans for the Portland Harbor Superfund site.
