Budget estimate

$225,000 – $245,000

The advertised bid range is $225,000–$245,000, which represents the estimated contract value. Assuming typical profit margins for municipal utility construction (approximately 8‑12 %), the contractor could expect earnings in the low‑hundreds of thousands range. Factors influencing the final budget include the exact scope of demolition, material costs, labor rates under prevailing‑wage rules, and any change orders during construction.
