Budget estimate

$250,000 – $600,000

No explicit contract value is disclosed. Based on the listed quantities (≈ 550 items) and typical unit prices for custom‑fabricated steel bridge components ($400–$1,200 per item depending on size and complexity), a reasonable estimate ranges from roughly $250,000 for a low‑end pricing scenario up to $600,000 for higher‑end custom work. Factors influencing the final amount include material costs, welding labor rates, testing/sample requirements, and potential freight charges.
