�vERc INDIAN RIVER COUNTY G ,.,. SOLID WASTE DISPOSAL DISTRICT +�LORipp• BOARD MEMORANDUM -- Date: October 31, 2013 To: Joseph A. Baird, County Administrator From: Vincent Burke, P.E., Director of Utility Services Prepared By: Himanshu H. Mehta, P.E., Managing Director,Solid Waste Disposal District Subject: Amendment No. 3 to Republic Services for Rain Flap Removal Project & Approval to Install Fleetzoom monitoring system DESCRIPTIONS AND CONDITIONS: On March 19, 2013, the Solid Waste Disposal District (SWDD) Board approved a final payment to COMANCO Environmental Corporation (Comanco) for the Phase 2 construction of Cell 1 of Segment 3 Expansion in accordance with Bid No. 2012025. As part of this project, a "Rain Flap" or a temporary liner feature was constructed to bisect the 10 acre cell in half to reduce the generation of leachate from rain water. Our Class I Landfill Operator, Republic Services, has filled the bottom portion of the new cell to the half-way point and now the rain flap is ready to be removed. Our project engineer, Geosyntec prepared drawing and specifications under an existing work order and evaulated the bids obtained by Republic Services. Geosyntec recommends proceeding with American Environment Group, Ltd. (AEG) as a subcontractor under Republic Services to perform the rain flap removal project as the most qualified and cost effective vendor. Attachment 1 contains a full evaluation of the bids for this project. AEG has provided a proposal in the amount of $17,125.00 to perform the project. Adding a 10% management fee of $1,712.50 to Republic Services results in a not to exceed total project cost of $18,837.50. Although included in the bid specifications, staff recommends that we direct purchase a back-up leachate pump. Purchasing the pump directly will provide an approximate savings of $300 (7%sales tax and 10% management fee). Our project engineer, Geosyntec will be providing construction quality assurance services under a separate work order to ensure that the work is completed in accordance with FDEP rules and regulations. In addition to the above, this third amendment includes provisions to allow Republic Services to purchase, install, monitor and maintain an electronic monitoring system called Fleetzoom associated with our landfill gas system. This is a telemetry type system that will allow Republic Services to better monitor the performance and operations of the gas system.
