Shallotte Water Transmission Main

      The Shallotte Water Transmission Main Project seeks to provide transmission system redundancy and increased transmission capacity to areas located southwest of Shallotte, NC. The project will link the existing 30” water main, located at the intersection of Red Bug Road SW & Ocean Highway (Route 17), to the existing 24” water main at Booster Pumping Station 6 (5739 Washington Road SW, Shallotte). The Consultant shall identify, evaluate, document, and provide preliminary construction cost estimates for multiple (minimum of 3) potential routes. The consultant shall identify potential easement locations along each route and shall consult with NCDOT concerning encroachments needed within DOT rights-of-way.Consultant shall prepare an overview map of the potential routes using the latest digital aerial photos and other record data. The overview map shall indicate existing utilities and potential easements. The Consultant shall provide copies of the overview map and review the map with the Owner.The Consultant shall revise the overview map based on the Owner’s review comments and include the map in a report summarizing the consultant’s findings and recommendations. The Consultant shall recommend a preferred route.

Based upon the study and report, the Owner will select a desired route.

      Upon selection of the desired route by the Owner, the Consultant shall perform wetlands delineation sufficient for receipt of all Army Corps and NCDEQ 401 & Buffer Permitting Branch Permits. Wetland areas that are sufficiently dry that would result in only temporary impacts to wetlands shall be evaluated for pipe installation using open trench techniques.
      Consultant shall perform geotechnical evaluation at all likely directional drill locations and, if determined prudent, provide geotechnical evaluations at bore and jack locations and for structures having significant foundations or significant embedment into the existing ground. Geotechnical borings shall be advanced to refusal or to a depth adequate for pipe design (though not less than 5’ below the maximum depth of installation), whichever is encountered first. Geotechnical recommendations and soil boring logs shall be incorporated into the Contract Documents. The cost for geotechnical investigation shall be provided on a per each basis.
    3. SURVEY
      Consultant shall provide base mapping of the route inclusive of all aboveground and underground features. All aboveground features shall be surveyed, including breaks in elevation (centerline and top of ditch, etc.). An adequate number of elevation points shall be surveyed to develop contours of the area. Consultant shall clearly indicate all utilities, indicating size, type, and owner information. Survey data shall be supplemented by existing maps, as-builts, and utility locates. As appropriate, base mapping will indicate both edges of pavement and existing utilities on both sides of the roadway. Additionally, edges of wetlands, geotechnical boring sites, and Subsurface Utility Engineering Quality Level A locates (potholing) shall be surveyed and clearly shown on the base mapping. Adjacent properties shall be identified by owner and parcel ID number. The cost for Level A locates shall be provided on a per each basis.
      The design of new 24” water main, complete with all connections and appurtenances (restraints, stub outs, fire hydrants, air relief valves, isolation valves, services, etc.) shall be required to make connection at the selected points.
    5. It is expected that the design will include both open-cut and trenchless pipe installation methods. Open-cut installations shall use ductile iron pipe as the base bid with PVC as an alternative bid item. Trenchless installations shall use HDD Fusible PVC as the base bid with HDPE pipe as an alternative bid item. For HDD installations, any HDPE pipe used shall be upsized to provide the best-match interior diameter to the piping installed by open cut methods.Consultant shall prepare design drawings, details, and technical specifications adequate to apply for and receive all necessary governmental approvals (local zoning approval, permits, encroachments, etc.). Preliminary Drawings shall clearly indicate easement areas, check valves, shut-off valves, directional drill locations, bore and jack locations, air release valves, vaults, and bypass piping as needed. The Owner shall submit comments to the Consultant which the Consultant shall then incorporate into the Preliminary Plans.
      Upon approval of the Preliminary Drawings, the Consultant shall prepare and submit permits and permit fees to regulatory agencies. These may include, but not be limited to:

      • NCDOT Encroachment Agreement
      • US Army Corps Permits and/or Notifications (401/404 Permits)
      • NCDEQ 401 & Buffer Permitting Branch Permits
      • NCDEQ Division of Water Resources Public Water Supply Section Permit
      • NCDEQ Division of Energy, Mineral, and Land Resources Erosion and Sediment Control Permit

    Upon notice by the Owner, the Consultant shall prepare easement maps. Mapping shall comply with the requirements of the local zoning officer, Register of Deeds, and the local (Brunswick County and Town of Shallotte) planning departments. Consultant shall receive all signatures from Zoning Compliance Officers and Planning Department personnel necessary for recording of the maps. Initially, twenty easements will be required with provision in the final contract to add or delete easement maps as necessary on a per each basis.
    Standard County “front end” documents shall be provided to the Consultant for use in preparing the final Contract Documents. These shall be modified by the Consultant for items specific to the project. The Consultant shall review and utilize Brunswick County standard technical specifications when available and applicable and shall supplement Brunswick County technical specifications as needed.
