Mr.Himanshu Mehta,P.E. 6 March 2013 Page 2 During construction of the Phase 2 project, SWDD requested Geosyntec to assess the condition of the ditch on the southern side of the vertical expansion access road that goes up the IRCL. On October 24, 2012, Geosyntec issued a memorandum to SWDD summarizing the assessment of the erosion and sedimentation issues the access road ditch was experiencing and proposed a ditch redesign to address the deficiencies of the existing ditch. Based on the performance and economic evaluations performed, Geosyntec recommended the use of Flexamae lining system to address the erosion and conveyance deficiencies of the existing ditch. Further, Geosyntec prepared an engineer's cost estimate (ECE) for performance of the Ditch Work. In December 2012, during performance of the Phase 2 project, SWDD requested Geosyntec to obtain a quote for the Ditch Work from the Phase 2 project general contractor Comanco Environmental Corporation (Comanco). On January 4, 2013, Comanco provided a quote for performance of the Ditch Work. The total cost from Comanco's proposal was $289,975.00. Based on the ECE, Geosyntec evaluated Comanco's bid price to be too high and suggested that SWDD rejects that and pursue other options. Geosyntec summarized Comanco's proposal evaluation in an 8 January 2013 memorandum to SWDD. On January 9, 2013, SWDD requested Geosyntec to prepare separate bid documents for the Ditch Work. Geosyntec subsequently completed the preparation of the bid documents including a revised bid form, technical specifications and construction drawings for obtaining bids for the Ditch Work. Geosyntec also revised the ECE in accordance with the revised bid documents. On January 25, 2013, SWDD requested Geosyntec to forward the bid documents for the Ditch Work to Republic Services, Inc. (Republic), the operator of the Class I Landfill, to obtain bids for construction of the Ditch Work under operation contract with SWDD.
