The Contractor shall replace existing potable waterline at Burnsville Dam, starting in the Downstream Area at the Burnsville Public Utilities Board (BPUB) meter, continuing by the office, through the Riffle Run Marina / Launch Area, and connecting to an existing line at the entrance to Riffle Run Campground, in accordance with the attached Plan Drawings. The project area is located at Burnsville Dam, and is shown on the Location and Vicinity Maps in the attached plan drawings. The existing main waterline shall be installed, tied-in to the existing system as shown, tested, and disinfected for a complete turn-key product. The Recreation Areas will be closed during construction of this contract; therefore, no provisions to maintain existing water service in Riffle Run Campground, the marina, or Downstream are required. However, the office and shop will remain open, so the existing line supplying these facilities shall be left intact until the new line is put in service. All excavation is unclassified; however, based on previous excavations in the area, solid rock excavation is expected in some areas.
