Budget estimate

$200,000 – $1,000,000

The estimated budget for this contract is difficult to determine, as the RFP does not provide a clear estimate of the contract value. However, based on the scope of work and the fact that the contract is for a two-year term with optional extensions, it is possible that the contract value could be in the range of $200,000 to $500,000 per year, depending on the level of services required. Factors that may influence the likely payment range include the level of emergency response required, the number of tree risk assessments and pruning/removal operations, and the cost of plant health care and other services.
