DeSoto County Regional Wastewater Treatment Plant Expansion Construction Engineering and Inspection Services

SCOPE OF SERVICES
I. BACKGROUND:
The DeSoto County Board of County Commissioners (BOCC) are seeking services from a qualified engineering firm (herein referred to a “RFQ respondent”) to provide Construction Engineering and Inspection Services for the expansion of the DeSoto County Regional (DCR) Wastewater Treatment Plant (WWTP) including effluent disposal facilities located at 7728 SE Highway 31, Arcadia, FL 34266.
The DCR WWTP (FDEP Facility ID FLA530808) is an extended aeration wastewater treatment plant with a current rated capacity of 0.750 MGD and plans to expand capacity to 0.950 MGD by the end of the 2022 calendar year. The WWTP is located on a 160-acre County owned parcel on SE Highway 31 with Property ID 02-39-25-0000-0011-0000. The current method of effluent disposal for the 0.750 MGD current rated capacity and the expansion to 0.950 MGD is the existing spray field located on the leased parcel to the north and east of the County owned site with Property IDs 02-39-25-0000-0010-0000 and 01-39-25-0000-0010-0000. Refer to Exhibit ‘A' herein which depicts the location of the above-mentioned County owned and leased parcels.
In April 2022, DeSoto County completed a wastewater facility plan which outlined recommended methods for increasing the existing DCR WWTP capacity. Engineering design and permitting services were retained through an RFQ in 2023. Design and Permitting are complete and the Construction is currently advertised scheduled for award Early December 2025. Design included expansions in two separate phases from 0.950 MGD to at least 1.40 MGD and 2.0 MGD. The selected RFQ Respondent will be responsible for the Construction Engineering and Inspection Services of both phases of expansion for the wastewater treatment plant and the effluent disposal. The County may elect to proceed with the two-phased expansion under two separate contracts awarded individually at different times or under one contract for phase 1 with an optional additional scope or change order for phase 2. This will depend on the bids received and available funding. As part of the negotiation phase, DeSoto County will discuss the production of separate scope and fee schedule for each phase vs. a single schedule for the both phases with the selected RFQ Respondent and reach an agreement on the preferred method prior to contract execution. The County should have better information on which phases are included when the negotiation phase is reached. The selected RFQ Respondent shall include applicable licenses to perform the Scope of Services in the State of Florida. The RFQ Respondent shall include any other necessary professionals on the team needed to complete this Construction Engineering and Inspection Services.

The anticipated schedule for this project is as follows:

The anticipated construction budget for the expansion of the DCR WWTP from 0.950 MGD to 1.40 MGD is $6.9 Million. The County may elect to expand the WWTP from 0.950 MGD in one phase. The anticipated construction budget for the expansion of the DCR WWTP from 0.950 to 2.0 MGD is $13.0 Million. II. DELIVERABLES:
