Charleston Water System is seeking qualified contractors to perform a detailed inspection and sonar profiling of a 2.5-mile submerged tunnel in Berkeley County, South Carolina, using Remote Operated Vehicles or equivalent technology. The tunnel spans two privately owned properties, requiring coordinated access and security clearance from both landowners. Respondents must possess proven experience and specialized equipment suitable for deep water, fully submerged tunnel inspections, with all work conducted on-site at the tunnel location. This solicitation is a pre-qualification process under NAICS code 237990, issued as Solicitation Number 2152 and posted on July 13, 2026, with responses due by August 3, 2026. All submissions must be made electronically through the PlanetBids portal in a single PDF format; mailed, faxed, or hand-delivered proposals are not accepted. The procurement is managed by the South Carolina state-level agency, with Kay Kelly as the primary point of contact. No formal contract types, evaluation factors, award basis, or clause requirements are specified in the solicitation, as this phase is solely focused on pre-qualifying vendors based on technical capability and equipment suitability. There are no stated contract values, payment terms, accounting codes, or designated contracting officer representatives, as the outcome of this solicitation will enable eligible firms to participate in future bidding for the actual inspection contract. No packaging, labeling, or inspection standards beyond industry best practices for underwater tunnel assessment are detailed, and no socioeconomic set-asides or representation certifications are referenced.
