Budget estimate

$500,000 – $2,000,000

The budget for this project is difficult to estimate without more information on the scope of work and the number of features to be closed. However, based on the bid schedule, it appears that the project will require a significant amount of labor and materials, including grating, concrete, and equipment. A rough estimate for the project could be in the range of $500,000 to $2 million, depending on the complexity of the work and the number of features to be closed. Factors that may influence the likely payment range include the location of the project, the type and number of features to be closed, and the level of environmental remediation required.
