This agenda item requests authorization for CDM Smith to initiate Phase III of the Project under IRC Landfill <br />Amendment No. 2 to Work Order No. 1. <br />ANALYSIS: <br />CDM Smith has prepared IRC Landfill Amendment No. 2 to Work Order No. 1, provided in Attachment 1, for <br />engineering construction services detailing the scope of work, budget, and schedule for the project. The <br />fees to be paid by SWDD for the execution of this work authorization are in accordance with the engineer's <br />continuing consulting services master agreement. The table below shows the expected completion date <br />and their estimated fees. <br />__TASK IF <br />ESCRIPTION <br />Task 2 — Project Quality Management <br />AMOUNT <br />$ <br />108,970 <br />Lump Sum <br />Task 7—General Engineering Services During Construction <br />$ <br />551,125 <br />Lump Sum <br />Phase <br />III <br />Task 8—Specialty Engineering Services During Construction <br />$ <br />84,580 <br />Lump Sum <br />Task 9 — Resident Services During Construction <br />$ <br />403,105 <br />Not To Exceed <br />Task 10— Liner System QA/QC 1 <br />$ <br />174,370 <br />Not To Exceed <br />Total 1 <br />$1,322,150 <br />The construction of a new landfill cell or a closure of a landfill cell is a highly sophisticated process wherein <br />rolls of high density polyethylene (HDPE) liners or low-density polyethylene (LDPE) geomembranes are <br />sewn together to cover acres of the site. The proper installation of these liners is critical to the long-term <br />integrity of our landfill as well as the protection of the underlying groundwater system. In addition, this <br />project involves the installation of imported fill worth over $5,000,000 that must meet certain delivery and <br />installation specifications. Also included in this project is the expansion of the landfill gas system, which will <br />add over 40 new gas wells, header piping, pumps, etc. that need to be installed to precision. Finally, a <br />leachate collection system, stormwater management facilities, a new lift station, a water main extension, <br />and a proper access road to support future expansion are included in this project. All these activities <br />require field inspections, liner quality assurance/quality control, review of shop drawings and laboratory <br />tests, documentations of installed work, review of field change requests, and proper tracking of invoices <br />throughout a 390 -day project period. <br />Between 2009 and 2013, the SWDD had various closure and new cell construction projects wherein the <br />total engineering fee vs. the total construction was approximately 10%. During the past 5 years, we have <br />seen both a tremendous increase in material costs as well as an increase in engineering fees. Upon approval <br />by the Board, the total cost for Work Order No. 1 would increase to $2,012,649, which is approximately <br />14% of the total estimated base construction cost of $14,576,600. <br />FUNDING: <br />The Segment 3 Cell 2 Expansion and Segment 2 Partial Closure projects are funded from separate revenue <br />sources; specifically, the closure cost is paid from an escrow account long established per FDEP <br />requirements. Annually, CDM Smith prepares a Financial Assurance Report in which they recommend <br />amounts that the SWDD should collect and place in the closure escrow account. <br />The Segment 2 Partial Closure project has been given a substantial completion time of 180 calendar days, <br />and the Segment 3 Cell 2 expansion project has been given a substantial completion time of 360 calendar <br />days. Therefore, both projects will include work/invoicing in the current fiscal year and next fiscal year. <br />@BCL@140E594C.doc Page 2 86 <br />
