EXHIBIT A WORK ORDER NO. 1 INDIAN RIVER COUNTY LANDFILL SEGMENT 3 CELL 2 EXPANSION, SEGMENT 2 PARTIAL CLOSURE, AND LANDFILL GAS SYSTEM EXPANSION PHASE I - MEETINGS, DESIGN DUE DILIGENCE, SURVEY, AND GEOTECHNICAL INVESTIGATION This Work Order, when executed, shall be incorporated in and become part of the Agreement for Engineering Consulting Services for Indian River County Landfill between Indian River County Solid Waste Disposal District (SWDD) and CDM Smith Inc., (CONSULTANT), dated July 2017 hereafter referred to as the CONTRACT. BACKGROUND The SWDD, the owner and operator of the Indian River County Landfill, has requested that CONSULTANT prepare this Work Order to provide professional engineering services for the proposed Class I Landfill Segment 3 Cell 2 expansion, partial closure of Segment 2, and expansion of the landfill gas collection system (Project). The proposed new cell is Cell 2 of Segment 3 (approximately 10.6 acres in size), as shown on Drawing No. 5 of the 20 -Year Permit Drawings dated September 2015. Segment 3 Cell 2 will be located immediately to the east of the existing Segment 3 Cell 1. The proposed partial closure of Segment 2 (approximately 25 acres in size) includes closure of the Segment 1/Infill vertical expansion area and the final elevations of Segment 2, which has been historically been referred to as the Segment 2C area. Expansion of the landfill gas system within Segment 2 is proposed to be constructed concurrently with the partial closure of Segment 2 so that the final components can be installed prior to the closure cap being constructed. This Project will be completed in multiple phases. Phase I includes evaluation of available information and developing sufficient information to update/revise existing permit design drawings and complete the final design and specifications that will be used for procurement. Subsequent phases will include preparation of the final design and bid package, permitting/regulatory agency support, bidding assistance, and engineering services during construction. The Scope of Services for Phase I of this Project is described below: SCOPE OF SERVICES CONSULTANT will undertake the design, bidding, permitting, and engineering services during construction of the Class I Landfill Segment 3 Cell 2 expansion, Segment 2 partial closure, and landfill gas system expansion located at the Indian River County Landfill. The design will include the Segment 3 Cell 2 bottom liner system, leachate collection and conveyance systems, and stormwater management facilities; Segment 2 partial closure cap liner system and stormwater management facilities, and the Segment 2 landfill gas system expansion. This scope of services includes work necessary to revise the existing permit drawings as necessary and to prepare final design drawings and specifications suitable for procurement of construction services by the SWDD. Based on recent discussions with SWDD staff and our familiarity with the landfill site, the proposed Scope of Services in this Work Order includes the following tasks: A-1 112046_Exh ibits.docx
