N. Nassau Street Pipe Replacement Project RFQ (Design Services)

The City of Charleston seeks a qualified design consultant to upsize existing underground utilities and install new drainage boxes along N. Nassau Street (from Isabella St. to Newmarket Creek) to alleviate chronic flooding. The consultant must be capable of meeting the city’s Small Business Enterprise (SBE) participation goals. This RFQ emphasizes design services rather than construction, requiring detailed engineering plans, hydraulic analyses, and coordination with city officials. • Scope includes pipe upsizing, new pipe installation, and drainage box design. • Must address flood mitigation for low‑lying street sections. • Contractor must comply with SBE goals set by the City of Charleston. • Submission deadline is October 30, 2026, 2:00 PM. • Primary contact: Grant Eversmann (Agency Project Coordinator).
