Budget estimate

$500,000 – $2,000,000

The budget estimation for this opportunity is based on the scope of services, which includes engineering services for three intersection improvement projects. The City of Davenport has been awarded a Safe Streets and Roads for All (SS4A) implementation grant, which will be the primary funding source for the project. Although the exact grant amount is not specified, the scope of work and the fact that it is a federally funded project suggest a significant investment. Assuming the grant amount is in the range of $5 million to $15 million, and considering the scope of services, a reasonable estimate for the engineering services contract would be between $500,000 and $2 million. This estimate is based on typical engineering service fees, which can range from 5% to 20% of the total project cost. Factors that may influence the likely payment range include the complexity of the projects, the level of expertise required, and the duration of the contract.
