Budget estimate

$120,000 – $160,000

The Engineer’s estimate puts the total contract value at about $140,000. Assuming typical contractor profit margins for small‑to‑medium public‑works projects (5‑15 % of contract amount), the net earnings could range from roughly $7,000 to $21,000. Accounting for potential change orders, overtime, or additional scope, a realistic budget range would be $120,000 – $160,000 in total contract revenue, with profit falling within the lower end of that band.
