Mr. Himanshu Mehta, P. E. 15 November 2022 Page 2 PROJECT BACKGROUND The IRCL facility is located in southern Indian River County, east 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 consist 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. This phase also includes: (i) abandonment of the perimeter ditch east of Cell 2 and construction of new perimeter ditches around Cells 3 and 4 footprints to tie into the existing ditch south of Cells 1 and 2 footprints; and (ii) abandonment of existing groundwater monitoring wells within Cell 3 footprint in accordance with the WQMP of the Class I Landfill permit; this also includes and abandonment and installation of a replacement LFG gas probe at the Class Landfill. • Phase 2: Construction of the Cell 3 liner and leachate control systems to be performed by a contractor selected through a separate procurement process. This proposal addresses the engineering design and construction support services required to complete Phase 1 of the Project, including preparation of construction and contract documents, contractor procurement support, construction management (CM), and construction quality assurance (CQA) services during the placement and compaction of the fill material for the subgrade. PROPOSED SCOPE OF WORK This project includes professional engineering design and construction support services that will be performed for the site preparation phase of the Project. The scope of work is based on the requirements of Chapter 62-701, Florida Administrative Code (F.A.C.) and Geosyntec's understanding of the Project based on information provided by the SWDD.
