Y--Bear Creek Road Phase II Construction and Potable Waterline Relocation

The Nashville District U.S. Army Corps of Engineers awarded a construction contract for the Phase II Construction and Potable Waterline Relocation of Bear Creek Road (BCR) in Oak Ridge, Tennessee. This is the notice of award. PROJECT DESCRIPTION: The relocation of BCR will tie in to the recently completed roadway on the east in the vicinity of the west end of the Polaris Parking Lot and, on the west, will tie-in to the existing Bear Creek Road just before the intersection with Old Bear Creek Road. The relocated BCR will be an urban-collector type road, compliant with Tennessee Department of Transportation (TDOT) standards. The road will have 12-foot lanes (one in each direction) with a 10-foot-wide utility shoulder on the south side and an 18-foot-wide utility shoulder on the north. A precast concrete beam bridge will be erected so BCR will pass over the haul road to prevent traffic into the Y-12 Complex from being interrupted or delayed by trucks on the haul road. The overpass will provide minimum vertical clearance of 20 feet, and the lower road will have a minimum width clearance of 45 feet for the full length. The BCR relocation scope consists of: Roadway construction, including overpass Tie-in to BCR eastern section Tie-in on the west just before the intersection of existing BCR and Old Bear Creek Road Steel casing for future duct bank crossing Drainage structures (including 3 retention ponds and storm drains) Safety appurtenances (i.e., guardrails, etc.) Signs and pavement marking Spur under the overpass with a base course of asphalt and temporary lane markings and signs Signalization, as determined by a study Construction of 4,000 feet of a City of Oak Ridge 24-in diameter waterline and ~3,600 feet of a plant 16-in diameter waterline, are part of the road construction. The new reinstalled potable water lines will parallel the relocated Bear Creek Road. The 24-in line will be installed in the 18-foot utility shoulder on the north side of the road, while the 16-in line, which will reduce to 12 inches, will be installed in the 10-foot shoulder on the south side. Installation will include new valve vaults in addition to use of existing valve vaults. Installation also includes electrical service for motor-operated valves and flow event date messaging; duct banks will be installed for lines and cables, and an existing control panel will be relocated and a new control panel installed. Although these waterlines and associated power will be installed in this WBS element, tie-ins to the City of Oak Ridge and Y-12 potable water systems, as well as electrical tie-ins will occur in a following phase of work.
