Budget estimate

$500,000 – $20,000,000

The budget for this opportunity is difficult to estimate as the document does not provide a specific budget or contract value. However, considering the scope of work, which includes providing professional engineering services for a stormwater management program, the contract value could be substantial. The fact that the County is seeking to establish one or more fixed-fee, open-ended contracts for Professional Engineering Services suggests that the contract value could be in the range of $500,000 to $5 million per year, depending on the number of contracts awarded and the scope of work. Additionally, the contract has up to three additional one-year renewal options, which could increase the total contract value over the four-year period. Therefore, the estimated budget range for this opportunity could be between $500,000 and $20 million over the four-year period.
