Budget estimate

$6,000,000 – $8,000,000

The bid documents list an estimated contract value of $7,500,000. Considering typical profit margins for large‑scale utility construction (5‑10 %), the contractor’s net earnings could range roughly from $6 M on the low end (assuming tighter margins or higher risk) to $8 M on the high end (if the project is completed efficiently with change‑order savings). This estimate reflects the scope’s breadth—multiple wells, extensive civil and mechanical work, and a lengthy 1000‑day schedule.
