Budget estimate

$100,000 – $300,000

The solicitation does not disclose a budget, but comparable biological consulting contracts for municipal or tribal utilities typically range from $100 k to $300 k for multi‑project scopes. Factors influencing the estimate include the number of miscellaneous projects, complexity of regulatory reviews, travel costs to remote sites, and the level of detailed reporting required. A modestly sized firm with relevant expertise could expect to earn in the low‑to‑mid six‑figure range, while a larger firm handling a higher volume of work could approach the upper bound.
