Z--Barkley Dam Tainter Gate Painting, Grand Rivers, Lyon County, KY

Barkley Dam is located at river mile 30.6 above the mouth of the Cumberland River in Western Kentucky. The Dam is adjacent to the town of Grand Rivers, KY along State Highway 62. The Dam is comprised of two embankment sections, a navigation lock, a powerhouse, and a spillway section. The spillway section is made of 12 tainter steel gates each 50 feet tall by 55 feet wide mounted on concrete spillway piers. The gates are operated by overhead machinery. The spillway section also includes an overhead gantry crane which is used to move bulkheads for unwatering and performing maintenance on the gates. The project includes only enough bulkheads to unwater one gate at a time. Access to the tainter gates is best from the east side at the powerhouse. The 12 tainter gates have many areas of light corrosion and a few areas of heavier corrosion. The upstream skin plate paint does not contain lead. Downstream skin plate, strut arms, diagonal bracings, stiffeners, vertical ribs, trunnion anchor beams and other coated metal on the gate contain lead. The work covered by this contract includes surface preparation and coating of the spillway gates. The Contractor shall also remove and dispose of all wood, tires, buoys or other debris collected on the gates. The Contractor shall provide all materials, equipment, and labor necessary to complete the work and ensure that the spillway gates and appurtenant areas are clean and ready for operation. The Contractor shall also be responsible for disposing of any materials removed from the gates during this work. The bid schedule is set up with the base bid to include gates 1, 3, 10, 11, and 12 and each of the remaining gates is set up as an option.
