Budget estimate

$2,000,000 – $5,000,000

Based on the scale of replacing multiple unit substations and switchboards within a major state government campus, the project is likely to fall in the multi‑million‑dollar range. Factors influencing the estimate include the number of substations (potentially 5‑10 units), the cost of high‑voltage equipment, demolition and disposal fees, and the need for commissioning and testing. A reasonable ball‑park would be between $2 million and $5 million for the full scope of work.
