Budget estimate

$500,000 – $2,000,000

The budget for this opportunity is difficult to estimate, as the document does not provide a specific budget or payment amount. However, considering the scope of work, which includes on-call professional engineering services for stormwater management, the budget could range from $500,000 to $2 million per year, depending on the frequency and complexity of the services required. The factors that may influence the likely payment range include the number of contracts awarded, the scope of work, and the level of expertise required. Given the City of Manassas's budget and the typical costs of similar services, a reasonable estimate for the budget could be between $750,000 and $1.5 million per year.
