C-1 Addendum No. 1 – Fort Avenue Sewer Replacement
This is an engineering plan and addendum document prepared by B&B Consultants, Inc. for the Town of Blackstone, Virginia, detailing the Fort Avenue Sewer Replacement project in New Kent County. The addendum, issued May 1, 2026, addresses relocation of Manholes A-3 and A-4 per railroad requirements. The project scope encompasses installation of approximately 172 linear feet of 10-inch SDR-18 PVC sanitary gravity sewer at 1.64% slope, 141 linear feet of 10-inch SDR-35 PVC at 0.88% slope, 15 linear feet of 10-inch SDR-35 PVC at 0.40% slope, and 13 linear feet of 8-inch SDR-35 PVC for reconnection. The work includes a 131 linear feet 18-inch bore and jack steel casing beneath Norfolk Southern Railroad crossing and four proposed manhole installations (A-1 through A-4) with existing manhole abandonments. The plan identifies a 20-foot by 40-foot boring pit and 10-foot by 10-foot receiving pit, temporary silt fence, and pavement sawcut and restoration requirements along Fort Avenue and Irvin Street. Construction involves coordination with Norfolk Southern Railroad requirements, adherence to NSCE-8 Specifications, and compliance with American Railway Engineering and Maintenance-of-Way Association Specifications for pipeline crossings, with blasting prohibited.
The technical specifications detail invert elevations, pipe slopes, manhole top elevations ranging from 427.47 to 431.77 feet, and manhole interior epoxy coating requirements. The project crosses railroad right-of-way with a variable-width permanent utility easement established across parcels owned by Andrew C. and Debra A. Damon (Parcel ID: 50-A26-5-17, Instrument No.: 23-23-734-50). The plan is scaled at 1 inch equals 20 feet horizontally and 1 inch equals 5 feet vertically, providing profile views and cross-sectional details for contractor reference. Prior revisions dated June 18, 2025, and July 7, 2025, addressed earlier railroad coordination changes. The expected construction duration remains 120 days to final completion, with sealed bids due May 12, 2026, at 2:00 pm at Town Hall, 100 West Elm Street, Blackstone, Virginia 23824.
