Timber Lane/Pickett Road Force Main Replacement
- STUDY AND REPORT PHASE
The Timber Lane/Pickett Road Force Main Replacement Project seeks to replace an existing 10” SDR 21 PVC force main with a new DR-18 PVC force main. The new main will follow the general alignment of the existing force main in this area and the existing main must remain in service until the new force main is available for use. The Consultant shall evaluate and document any recommended route changes for the new force main. Additionally, the Consultant shall recommend the best sized pipe to replace the existing 10” force main. It is anticipated that the existing 10” force main will be replaced with a new 10” force main but this needs to be verified. Consultation with the Town of Leland shall be required to verify anticipated future flows from the Magnolia Greens Pump Station. Any required easements shall be identified in this phase. Consultant shall prepare an overview map of the recommended route indicating existing utilities and potential easements using the latest digital aerial photos and other record data.
The Consultant shall provide copies of the recommended route map and review it with the Owner for any modifications or comments.
- WETLANDS DELINEATION
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. It is not expected that any wetlands shall be encountered or that there will be need for directional drills.
- GEOTECHNICAL INVESTIGATION
It is not expected that geotechnical investigation shall be needed. However, if needed, 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.
Consultant shall provide base mapping of the route inclusive of all above ground and underground features. All above ground 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.
- PRELIMINARY DESIGN PHASE
The design of approximately 3,600 linear feet of new DR-18 PVC force main complete with all connections and appurtenances (restraints, stub outs, air relief valves, isolation valves, services, etc.) shall be required to make connection at the designated points. The design may include both open-cut and trenchless pipe installation. A check valve vault, metering vault, and necessary easements shall be included.
Consultant shall prepare design drawings, details, and technical specifications adequate to apply for and receive all necessary governmental approvals (zoning approval, permits, encroachments, etc.). For directional drills, HDD Fusible PVC shall be used as the base bid and HDPE pipe shall be shown as an alternate. Any HDPE directional drill piping shall be upsized to provide the best-match interior diameter to the piping installed by open cut methods. 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:
- 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 including Engineering Report
- NCDEQ Division of Energy, Mineral, and Land Resources Erosion and Sediment Control Permit
- NCDEQ Division of Energy, Mineral, and Land Resources Stormwater Permit
Brunswick County Stormwater Permit (as needed)The Consultant shall perform field work, furnish plans and specifications, prepare documents, attend regulatory and governmental meetings, respond to questions and comments, evaluate alternatives, and provide recommendations concerning wetland permitting.
- FINAL DESIGN PHASE
Upon receipt of the NCDOT Encroachment Agreement or notice by the Owner, the Consultant shall prepare final design drawings, details, and Contract Documents for bidding purposes. The Consultant shall provide an updated Opinion of Probable Cost. The Owner shall submit comments to the Consultant which the Consultant shall then incorporate into the Final Plans.
- EASEMENT MAPS
Upon receipt of the NCDOT Encroachment Agreement or 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 Brunswick County Planning Department. Consultant shall receive all signatures from Zoning Compliance Officers and Planning Department personnel necessary for recording of the maps. Initially, one easement will be required with provision in the final contract to add or delete easement maps as necessary on a per each basis.
- BIDDING AND NEGOTIATING PHASE
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. The Consultant shall ensure there is no overlap between the Consultant’s technical specifications and the County’s standard “front end” documents. The Consultant shall assist in advertising the project; conduct a pre-bid meeting; post bid documents to plan room Internet sites; provide all necessary hard copy Contract Documents; respond to Contractor questions; evaluate substitutions; prepare and distribute addenda and clarifications; attend bid opening; review bids; provide certified bid tabulation; assist with bid protests; make recommendation of award; consult with Owner on the acceptability of Contractors, suppliers, and manufacturers; and assist Owner in negotiations with Contractors.
- CONSTRUCTION PHASE
Consultant shall provide sufficient project inspection and shall consult with the County Inspector sufficiently for the Consultant to provide all necessary certifications at the close of the project. Consultant shall evaluate all test reports; assist Owner in selection and/or approval of an independent testing laboratory; review construction observation reports; ensure compliance to the Contract Documents; prepare conformed documents; conduct a pre-construction meeting; conduct monthly progress meetings; inspect the project no less than once per week and document inspection findings; review shop drawings and required submittals; review schedules (Progress, Submittal, Values); review Requests for Information; issue clarifications and interpretations of the Contract Documents; prepare change orders and work change directives; review and approve applications for payment; develop punch lists; review maintenance and operating instructions, guarantees, and bonds; and conduct final walk-throughs. The Consultant shall prepare Record Drawings showing appropriate record information based on project annotated record documents received from Contractor and furnish such Record Drawings to Owner. The Consultant shall prepare operation and maintenance manuals as required. The Consultant shall assist the Owner in determining the date of Substantial Completion and Final Completion.
- POST-CONSTRUCTION PHASE
Visit the project to observe any apparent defects in the work, assist Owner in consultations and discussions with Contractor concerning correction of any such defects, and make recommendations as to replacement or correction of defective work, if any. Visit the project within one month before the end of the Construction Contract’s warranty period to ascertain whether any portion of the work is subject to correction and provide Owner a report of findings. Verify any warranty work completed by the Contractor is in compliance with the Contract Documents.
