About this file
This document is a pay item descriptions exhibit from a Request for Proposals issued by Volusia County, Florida for a leachate evaporation system demonstration project at the Tomoka Farms Road Landfill. The project requires the contractor to furnish, lease, install, and operate leachate evaporation systems in two existing leachate storage ponds, designed to achieve an average evaporation rate of 100,000 gallons per day over a six-month demonstration period. The scope of work includes providing all labor, materials, equipment, piping, valving, wiring, anchors, power, utilities, and a measurement and monitoring plan to demonstrate system performance above ambient conditions. An engineer-approved monitoring plan must be submitted within 30 days of the Notice to Proceed. The County will provide access to pond inflow pipe locations and available records to support the contractor's development of the performance measurement plan and will implement the approved plan under contractor supervision.
The contract structure offers two payment pathways: a lease-with-return option for the six-month demonstration period or a lump-sum buy-out option following successful demonstration. Mobilization costs shall not exceed 10 percent of the grand total for the lease-with-return option and are paid on a percent-complete basis. For the lease-with-return option, the contractor receives a partial payment following delivery, installation, start-up, and monitoring plan approval, with subsequent pro-rata payments until demonstration completion and final payment upon equipment removal and return. If the County elects the lump-sum buy-out option based on the system meeting project criteria, monthly lease payments from the demonstration period are applied toward the purchase price. Demobilization must be completed within 30 days of a letter of intent should the demonstration be unsuccessful, with payment made upon completion at the lump-sum cost.
