Mr.Himanshu Mehta,P.E. 15 October 2013 llftwPage 2 During construction of the Phase 2 project, an east-west diversion berm and a rain flap were constructed to divide Cell 1 into approximately two halves in order to separate the landfilling and leachate in the northern half of the cell from the stormwater in the southern half of the cell. A pump was installed at the low point in the southern half to pump out the collected stormwater to the perimeter drainage channel. Since inception of waste acceptance within Cell 1, Republic Services Inc. (RSI), the Class I landfill operator, has been placing waste within the northern half of Cell 1. Geosyntec understands that with the current on-site waste operations, RSI would like to utilize the southern half of Cell 1 for waste placement. In order to utilize the southern half of the Cell, the east-west rain flap needs to be removed, and the leachate collection system (LCS) for Cell 1 including the primary geocomposite drainage layer, leachate collection pipe and leachate collection corridor (aggregate)need to be connected. In view of the above, SWDD decided to obtain bids for removal of the east-west rain flap through RSI under their operations contract. On September 24, 2013, SWDD requested Geosyntec to prepare bid documents for the Project. Geosyntec subsequently completed the preparation of the bid documents including a bid form and construction drawings for obtaining bids for the Project. .. SUMMARY AND EVALUATION OF BIDS On October 14, 2013, RSI forwarded to Geosyntec bids received for the Project from three (3) RSI approved vendors/general contractors: • Comanco Environmental Corporation (Comanco), Plant City,Florida; • American Environmental Group, Ltd. (AEG), Richfield, Ohio; and • Environmental Specialists International, Inc. (ESI), Baton Rouge, Louisiana. Attachment A includes the bids submitted by the contractors. Geosyntec utilized the bidders' completed forms to prepare the Summary of Bids table presented in Attachment B. The table shows that the total bids are: (i) $28,300.00 for Comanco; (ii) $19,625.00 for AEG; and (iii) $25,000.00 for ESI. AEG is the lowest bidder among the three. It is noted that ESI provided a lump sum amount for the entire work and did not provide a breakdown of cost per item on the bid form. In general, the price quoted by Comanco for items 1 (mob/demobilization), 3 (rain flap removal), and 4 (materials) were comparable with the prices quoted by AEG. However, the price quoted by Comanco for item 2 (dewatering) is 100 percent more than that quoted by AEG. Also, the price quoted by Comanco for item 5 (pump) is about 220 percent more than that quoted by AEG. lfta. FL1321UL13078_Bid Evaluation_RainFlap Final.doc 183
