Description

The City of Cincinnati is seeking qualified firms to conduct a comprehensive feasibility study for a proposed subway tunnel. The study will evaluate engineering, financial, environmental, and regulatory aspects to determine the viability of constructing an underground transit system through Cincinnati. The selected contractor will be responsible for data collection, modeling, cost estimation, risk analysis, and preparing a final report with recommendations for the City’s decision‑making. • Scope includes geotechnical investigations, alignment studies, ridership forecasting, and preliminary cost/benefit analysis. • Deliverables: technical reports, financial models, environmental impact summaries, and a presentation to city officials. • Requires expertise in civil/transportation engineering, urban planning, and public‑sector project financing.

Budget estimate

$200,000 – $800,000

Based on typical municipal feasibility studies for large‑scale transit projects, the contract is likely to fall in the mid‑six‑figure range. The scope—covering extensive engineering analysis, environmental review, and financial modeling—suggests a budget between roughly $200,000 and $800,000, depending on the depth of analysis, required subcontractors (e.g., geotechnical labs), and the level of detail in the final report.
