PROJECT BACKGROUND Tetra Tech is currently performing engineering services for Collier County Public Utilities under Contract #19-7621, Collier County Project # 70243.1 known as the Golden Gate Wastewater EOR and Infrastructure Improvements. The original authorization for Task 4 included expansion of the Golden Gate Wastewater Treatment Plant (WWTP) from 1.5 MGD to 3.0 MGD. The original concept included utilizing the existing biological treatment units and installing membrane bioreactor (MBR) units to meet the expanded capacity. Ancillary components included reclaimed water and reject storage, a flow equalization basin, an operations building, and upgraded electrical. As designed, the proposed facility will be significantly larger, designed with an initial treatment capacity of 5.0 MGD and master planned for a buildout capacity of 8.0 MGD.To be consistent with nomenclature,the facility is also being renamed to the Central County Water Reclamation Facility. With the larger facility comes the following upgrades: • An Enlarged headworks (sized for 8 MGD) • An enlarged flow equalization system with dual tanks • A new biological process system sized to treat 4.0 MGD (with future mirrored system) • An enlarged MBR system • A sludge holding tank, dewatering facility and screw press (sized for buildout) • (2) larger reject storage tanks • (2) larger reclaimed water storage tanks (bid alternate) • Demolition of the existing clarifier, digester, office and yard piping • Enlarged components including power feed, wiring, panels and generator • Additional instrumentation components associated with the additional and larger features The original authorization included an estimated construction duration of 510 days to substantial completion with an additional 60 days to final completion. Due to the increase in project size, construction duration will be 1,050 days to substantial completion and an additional 60 days to final completion. It is anticipated that the construction administration scope of work will extend six months beyond the construction contract period to account for regulatory certification, startup, and closeout. Additionally, this scope of services includes time for a 1-year warranty inspection, bringing the total duration of this scope of work to 1,655 days. The County has requested an expanded scope of services related to the construction administration of the treatment plant expansion. lit TETRA TECH TW/Golden Gate GG/Scope Tt#BP Collier County -1- CAG1 1 1 C SCOPE OF SERVICES Provided below is Tetra Tech's proposed scope of services.
