Specifications include, but are not limited to: The Commonwealth of Kentucky, Division of Engineering and Contract Administration (DECA) and the Department of Parks (Parks) is planning to replace the emergency spillway and raise the inlet of the principal spillway for the General Butler State Park Dam. The concrete emergency spillway was constructed in 1939 by the Civilian Conservation Corps and is in an advanced state of structural distress. The proposed emergency spillway replacement will consist of demolition of the existing 10 foot by 3 foot reinforced concrete box culvert, concrete drop structure, three (3) 48-inch CMP’s and concrete headwall. The new emergency spillway will be a reinforced concrete structure consisting of a 12 foot by 4 foot box culvert through the embankment, discharging to a chute spillway and stilling basin on the downstream side of the embankment. The overall length of the new emergency spillway structure is 133 feet. The stilling basin will discharge to a riprap channel. In conjunction with demolition of the emergency spillway, the CCC inscription on the culvert headwall on the upstream side of the dam shall be removed intact by saw cutting and the resultant slab preserved for display. The Contractor shall submit a plan prior to demolition, approved by the Design Team and General Butler personnel, for preservation of the concrete slab. The plan shall also include design of a pedestal to support the slab. The principal spillway for the dam was replaced in 2014 and the new inlet which was installed lowered the previous normal pool elevation of the lake. The principal spillway structure inlet will be raised approximately 1.4 feet by addition of a precast or cast-in-place concrete collar to the existing structure. The inlet raise will return the pool elevation of the lake to previous levels. Raising the inlet will also require raising the existing catwalk and either replacing or extending the slide gate controls, the Contractor shall submit a plan for approval to accomplish this work. The existing principal outlet headwall will be demolished and replaced with a new impact basin discharging to a riprap channel. Construction of the new emergency spillway will require a substantial excavation of the existing embankment and existing roadway. The entire length of the embankment will be receive new asphalt pavement consisting full depth replacement over the excavation area and overlays elsewhere. The project requires removal and replacement of an existing wooden walkway located on the upstream side of the dam near the east abutment. The Contractor will be responsible for restoring the walkway to its current condition utilizing either salvaged existing or new materials. Any deviation from the current configuration will require prior approval by the Design Team and General Butler State Park personnel. All slopes shall be regraded and disturbed areas will be seeded and mulched. Open areas of the new structures will receive fencing as shown on the Construction Drawings.
