Summary of Scope of Work: The work for this project will consist of the following major elements: The removal and replacement of Diversion Dam diffuser baffles (approximately 36), core-drilling within the radial gate pier walls, and the metal fabrication of steel safety stops for the Diversion Dam radial gates. The contractor is to remove the existing damaged baffle concrete without damaging the underlying reinforcement, and reconstruct each baffle with air-entrained concrete matching the original dimensions. Hydro-demolition is the preferred mechanism to achieve this task within the above parameters. Minor saw-cutting will be permissible to establish clean edges for bonding surfaces. Bonding agents will be required at the concrete cold-joints to prevent water intrusion. The contractor is to core-drill 5-inch diameter holes (n=8) within each of the eight radial gate pier walls. A 4.5-inch steel pipe will be grouted into each hole. The contractor will fabricate the newly designed 4-inch steel HSS safety stops with UHMW-PE rub pads. Ground penetrating radar (GPR) will be necessary to identify drilling locations in order to not damage the underlying steel reinforcement. On-site work will be April through September 2020; however this is subject to change due to higher than normal flows. The in-water work window for Mill Creek Project is July 15, 2020 through September 15, 2020. All on-site work shall be performed in accordance with the Corps of Engineers Safety and Health Requirements Manual (EM 385-1-1). The Contractor will be responsible for establishing and managing an effective on-site Safety and Health program in accordance with EM 385-1-1 that will require the development and submission of a comprehensive project specific Accident Prevention Plan for Government acceptance.
