Budget estimate

$500,000 – $1,200,000

Based on the total bid amounts ($9.8 M–$11.7 M) and typical contractor profit margins for public‑sector utility construction (5‑10 % of contract value), the expected earnings for the winning contractor would likely fall between roughly $500,000 and $1,200,000. The lower end assumes a modest 5 % margin on a $10 M contract, while the higher end reflects a 10 % margin on the upper‑range bid. Additional revenue could arise from the optional alternates if awarded.
