Mr. Himanshu Mehta, P.E. 1 December 2009 Page 2 • expansion and upgrade of the landfill gas collection and control system (GCCS) to enhance odor control at the IRCL site and potentially increase the extraction of landfill gas (LFG) for energy recovery and carbon offset credits; • partial closure of the North and South slopes of Segment 2 and Infill Area of the Class I Landfill to an approximate elevation of 105 ft National Geodetic Vertical Datum (NGVD) in order to control leachate seepage, minimize leachate generation and associated disposal and treatment, and also to comply with the Florida Department of Environmental (FDEP) permit requirements; • construction of storm water management system over the closed portions of the Class I Landfill to minimize the potential for leachate generation and convey clean storm water runoff to the on-site sedimentation pond for ultimate disposition; and • preparation of the borrow area located immediately north of the C-5 canal for excavation and stockpiling of soils for use as construction material for the vertical expansion and partial closure constriction project. Two construction contracts were awarded through WMIF, as the Construction Manager, to: (i) Environmental Specialties, Inc. (ESI), Baton Rouge, LA for the vertical expansion, GCCS, partial closure and storm water management construction; and (ii) Sawmill Ridge Trucking (Sawmill), Vero Beach, Florida for the preparation of the borrow pond area to facilitate excavation and stockpiling by the SWDD staff. The total contract price approved by the SWDD Board for the vertical expansion and partial closure construction component was $4,157,622.64. This amount is comprised of: (i) a lump sum bid price of $3,299,700.51 to ESI for the actual construction work; (ii) a 5% management fee to WMIF in the amount of $164,985.03; and (iii) a 20% contingency fee to account for potential change orders and changes in site conditions in the amount of $6929937.11. The contingency amount also included WMIF's management fee of 5 percent for any change order. It should, however, be noted that the lump sum contract to ESI included a unit cost/not-to-exceed (NTE) component for ten (10) work items that had to be paid based on actual quantities measured and surveyed. Depending on the measured and surveyed quantities for those items, the total contract amount could be less or more than, by a NTE amount of $11,120. Furthermore, the total construction cost was less than the Engineer's cost estimate range of $5,378,880 to $5,707,440, including the 20% contingency. The total contract price approved by the SWDD Board for the preparation of the borrow pond area to facilitate excavation and stockpiling by the SWDD staff was $298,864.53. This amount is FL 1537-01/JL90230.docx
