IFB 1195-25 Upper Harding Basin Sanitary Sewer Rehabilitation Project

Middlesex County, Virginia is seeking bids for the Upper Harding Basin Sanitary Sewer Rehabilitation Project (IFB 1195-25), a comprehensive infrastructure improvement initiative focused on sanitary sewer system rehabilitation. The project involves extensive sewer system work, including televising existing sewers, cleaning, inspection, manhole rehabilitation, and installing cured-in-place pipe (CIPP) liners. Contractors must demonstrate significant experience, specifically having successfully installed at least 1,000,000 feet of CIPP over 10 years, with a minimum of 100,000 feet being UV light cured CIPP. The project's primary objectives are to remove excessive infiltration and inflow, reduce sanitary sewer overflows, and improve overall system performance. Technical requirements include using approved CIPP products like Saertex Liner, Inliner STX, and Alphaliner, adhering to ASTM F2019-20 standards, and installing liner thicknesses ranging from 3mm to 15mm based on pipe diameter and depth. The bid solicitation was posted on February 10, 2025, with proposals due by February 20, 2025, and requires contractors to perform work within existing sewer easements while maintaining sewage flows through bypass pumping and implementing strict traffic control measures.

While no specific set-aside designations are explicitly mentioned in the documentation, the project requires contractors to have substantial technical expertise and proven track record in sewer rehabilitation. The work involves accessing and coordinating with property owners, restoring disturbed areas, and reconnecting active service laterals. Contractors must be prepared to handle complex rehabilitation tasks, including comprehensive manhole cleaning, sealing, and application of cementitious lining. The project will be implemented using engineering drawings and specifications prepared by CHA Consulting, dated December 2024. Although specific budget ranges are not detailed in the available documents, the comprehensive nature of the project—involving multiple rehabilitation techniques, extensive sewer system interventions, and sophisticated CIPP installation—suggests a significant investment in infrastructure improvement. The project covers the Upper Harding Avenue Sewershed and will likely require substantial technical capabilities, advanced equipment, and specialized knowledge in municipal infrastructure rehabilitation.
