Budget estimate

$200,000 – $500,000

The scope—full tunnel structural inspection, utility mapping, and a detailed 2027 report for a major airport facility—suggests a moderate‑size contract. Based on comparable civil‑engineering inspection projects at similar airports, the total contract value is likely between $200,000 and $500,000, depending on the depth of testing required and any supplemental consulting services. Factors influencing the range include the extent of non‑destructive testing, the need for specialized equipment, and the level of detail required in the final documentation.
