Mr. Himanshu Mehta, P. E. 28 March 2023 Page 2 PROJECT BACKGROUND The IRCL facility is located in southern Indian River County, cast of Interstate 95, south of Oslo Road, and west of Rangeline Road in Vero Beach, Florida. The SWDD administers the management and operation of the Class I landfill at the IRCL facility. The Class I Landfill includes the closed Segment 1/Infill/Segment 2 vertical expansion, and Segment 3 lateral expansion (Segment 3). The total footprint area of Segment 3 is 76 acres and consists of eight cells that are being constructed in phases as needed. Segment 3, Cell 1, directly east of and on top of the east slope of Segment 2, was constructed in 2013. Segment 3, Cell 2 was constructed in 2020. Republic Services of Florida LP (Republic), the operator of the Class I Landfill, has estimated that filling of Cell 2 will be nearly completed by the end of Calendar Year (CY) 2023 and has therefore recommended that SWDD considers construction of Cell 3 during CY 2023. In order to expedite Cell 3 construction, SWDD would like to implement it in two phases, as follows: • Phase 1: Site preparation activities consisting primarily of the earthwork for construction of the subgrade for Cell 3; the fill material will be obtained from off-site borrow sources with the actual placement and compaction to be performed by a contractor through the procurement process. • Phase 2: Construction of the Cell 3 liner and leachate control systems to be performed by a contractor selected through a separate procurement process. On 22 November 2023, the SWDD Board authorized Geosyntec to prepare the construction and contract documents, and contractor procurement support, construction management (CM), and construction quality assurance (CQA) services during the placement and compaction of the fill material for the subgrade for Phase 1 of Cell 3 construction. The request for bids from contractors is scheduled to be advertised by the County by 30 March 2023 with a bid opening date of 5 May 2023. This proposal addresses the engineering and support services required to procure a construction contract for Phase 2 of the Project, including preparation of construction documents, engineer's construction cost estimate, and contractor procurement assistance. Geosyntec understands that following the preparation of the construction bid documents and cost estimate, SWDD Staff intends to request SWDD's Board authorization to commence the bidding process for the project. PROPOSED SCOPE OF WORK This project includes professional engineering and support services that will be performed for the procurement of a construction contract for the approximately10.5-acre Cell 3 of Segment 3 of the NCP2323092UL23017 Cell 3 Liner Contractor Procurement - � tiCi('I11 ;yip ( IISl1r rA�tlti;-�
