$150,000 – $300,000

Based on comparable tunnel‑inspection and engineering‑consulting contracts for major airport infrastructure, a reasonable estimate ranges between $150,000 and $300,000. The lower end reflects a basic inspection and reporting package, while the higher end accounts for extensive engineering analysis, coordination with multiple agencies, and potential sub‑consultant involvement.
