Site work for a civil project in Richmond, California. Completed plans call for site work for a water / sewer project.

Veolia Water West Operating Services, Inc. operates and maintains the City of Richmond's Wastewater Treatment Facility (WWTF) and the associated sewer collection system. The work will include pipe segment replacement of deteriorated sewer pipe segments within the collection system using pipe bursting, open cut, or pipe reaming as discussed further below. The work shall include manhole installation and/or replacement and/or full interior surface (e.g. chimney, cone, wall, bench, and channel) rehabilitation when the adjacent pipeline is replaced, and manhole frames and covers as necessary. For pipe replacement work, pipe bursting is the preferred method, followed by open cut and then pipe reaming. The pipe segments to be replaced for this project are identified in Scope of Work Attachment A. The line segments identified may be modified from time-to-time during the project. The selected Contractor shall conduct a pre-CCTV of each line segment to the greatest extent possible to mark and locate the defects prior to commencement of the Work. A complete NASSCO graded post-construction CCTV survey of the entire line segment (manhole to manhole) shall be completed upon completion of the work (no later than one week after the repair or replacement) and provided to Veolia. If following the repair, the line remains inaccessible, the contractor shall provide a supplemental repair cost proposal with the CCTV video for consideration. The project scope includes, but is not limited to the following: 1. Contracting with a local Civil Professional Engineer to provide review and approval of each line segment installation, and preliminary engineering and design for the lines which have utility conflicts, or other constructability issues. The Engineer of Record shall submit an initial plan showing the lines that will receive preliminary engineering for review and concurrence, followed by 30 percent design drawings clearly showing all conflicting utilities, structures, and other field constraints and the contractor's approach to addressing these constraints as needed to complete the work . The contractor shall be responsible for addressing all field conditions, whether included or not included in the 30 percent design package, and whether shown or not shown on the submitted design. The initial plan and the 30 percent designs shall be approved in concept by the Owner. Separate designs may be provided for individual line segments in order to expedite the work. 2. Submit final as-built drawings and any intermediate design and modifications for all pipelines, including those that did not receive 30 percent design, to the Owner for approval. 3. Contractor shall provide a construction project schedule, including weekly schedules with crew information and locations as reasonably required by Veolia. 4. Contractor shall provide bi-weekly updates for progress of pipe replacement/repair work 5. Sheeting, shoring and bracing. 6. Trenching width shall be (Pipe OD + 24" MIN) or (Pipe OD + 36" MAX). 7. Potholing existing utilities based on mandatory USA markings. 8. All USA markings shall be removed from the pavement after work is complete. 9. Traffic control, as necessary per City of Richmond requirements. 10. Pipe replacement by pipe bursting, unless inadvisable or infeasible with authorization by Veolia and the City of Richmond. 11. Open Cut techniques permitted only if pipe bursting is not feasible and with authorization by Veolia and the City of Richmond. 12. Reconnection and/or extension of existing service laterals to new sewer main, as necessary. 13. Extending sewer laterals from the closest point of abandoned sewer mains to new sewer mains. Open cut or hand-digging may be required. 14. Removal of existing manholes or cleanouts and construction of new manholes, complete, as needed. 15. Rehabilitation of Manholes whenever the adjacent pipeline is replaced, per attached specifications. Vacuum testing of rehabilitated brick manholes is not required. 16. Post Construction cleaning of sewer pipe line segments that were replaced. 17. Post replacement NASSCO graded CCTV of the entire line segment. 18. Post construction NASSCO graded CCTV information shall be submitted no later than one week following the line segment replacement. 19. Restoration and repair of existing pavement systems shall be T-cut, and the Contractor shall be responsible for restoring surface improvements affected by the Work and incidentals for complete and usable sewer system. 20. If the Contractor encounters defective private sewer lateral connecting to the mainline, the Contractor shall replace up to 6 feet of the private sewer lateral from the mainline. 21. Replace striping with thermoplastic, traffic loops, and fire hydrant markers. 22. Handling and disposal of contaminated material if authorized by the Project Manager and the City of Richmond. 23. Dewatering and obtain appropriate permits, as necessary. 24. Construction shall be Monday thru Friday from 7am to 4pm. Contractor's request for weekend, offhours and holiday work may be considered on a case-by-case basis by Veolia Project Manager.
