Poe Gate 1 Blasting & Coating

The general scope of the project is the surface repair and coating of one miter gate leaf, approximately 63 feet wide by 35 feet tall. The gate will remain in place and would require a wind resistant, enclosed, climate controlled environment with a minimum temperature of 45 degrees Fahrenheit to be constructed around it. Cracked, pitted, or damaged gate surfaces that are discovered after initial surface preparation activities shall be adequately repaired. It is critical that the final surface preparation meets “white metal” in accordance with SSPC SP 5 criteria and that stringent full time technically qualified quality control is maintained during surface preparation and coating application. The coating is an USACE exclusive marine grade vinyl based coating that shall be applied immediately after welding repairs to stiffener plates, fender mounting brackets and final surface preparation activities. Some disassembly and reassembly of existing/new replacement gate components will be required, including grease lines, electrical conductors, signal lights, walkway platform, hand rail, flushing valves, timber fenders, structural stressing diagonals, gate seals, and access hatch. The Contractor will be required to furnish new gate seals, timber fenders and diagonals. Adequate lead time will be required to furnish these specialty items. New diagonals are currently being designed and the contractor will need to furnish and install. Design of new diagonals will differ from existing and install time will need to account for gate repair and coating activities. Work shall not exceed one season of winter closure activities. Protection of the gate anchorages, quoin blocks, miter blocks, hydraulic cylinder and connection, and pintles will be required throughout the project. Compressed air, natural gas, and electric will be provided by the Government if necessary.
