Budget estimate

$1,000,000 – $1,500,000

The engineer’s estimate for the project is $1.3 million. Considering typical bid‑to‑award adjustments, a reasonable contract value range would be between $1.0 million (lower‑end, assuming competitive bids) and $1.5 million (upper‑end, if additional scope or higher‑spec equipment is selected). Factors influencing the final budget include the selection of equipment manufacturers (e.g., Grundfos pumps added in Addendum 3), prevailing‑wage rates, and any bid substitutions.
