This procurement is designated as a Total Small Business set-aside with no identified incumbent contractors. The contract value is estimated between $1,000,000 and $5,000,000, with the Independent Government Estimate at $1,136,143.82 and actual bids received ranging from $926,800.00 (Civil Built LLC - lowest bid) to $1,741,000.00 (HB Hansen Construction). The project involves installing five FAST treatment units totaling 15,000 gallons of treatment capacity to serve multiple facilities including a marina sewage lift station, comfort station, and camp sites.
