This project included the design of twenty steel sheet pile river cells and associated dredging as part of a new lime barge unloading facility at the Mitchell Power Generating Station located on the Ohio River. The river cells are designed to moor and maneuver a raft of barges while being unloaded. A hydraulic "E-Crane" equipped with a grab bucket is located on top of one of the river cells and is used to remove the crushed limestone from the barges. This material is fed into a series of hoppers and conveyors that carry the product into the power station where it is ground to a powder then injected into the boiler flue gas to reduce sulfur emissions. The by-product of this process is gypsum, which is conveyed back to the facility and loaded into barges for shipment and further processing.

• Preparing a structural design with the goal of keeping the quantities of materials within the Contractor's initial budget estimate.
• Establishing the design criteria for the berthing, breasting and mooring cells based on industry standards and Owner's specific river barge requirements.
• Completing the design and construction to accommodate the Owner's aggressive schedule.
