ANALYSIS:
<br />SWDD is required by the Florida Department of Environmental Protection (FDEP) to properly close landfill
<br />cells that have reached final capacity. In addition, SWDD is required to maintain disposal capacity of the
<br />landfill to handle current and future waste from IRC residents.
<br />The Segment 2 area has reached its final permitted capacity elevation of 180 ft and therefore partial
<br />closure of the north, south and western portion, including the top, must be completed. The current
<br />Segment 3 Cell 1 is approximately 50% full; therefore, a new Sement 3 Cell 2 must be constructed to
<br />maintain future capacity.
<br />In addition, this project provides the expansion of the landfill gas system, which will provide additional
<br />odor control, reduce the possibility of a fire/explosion, and provide a potential to market the landfill gas.
<br />Also, this project includes the expansion of the water main system to the interior parts of the landfill with
<br />the installation of a fire hydrant near the yard waste processing site, which can provide critical water
<br />protection in case of a fire.
<br />ENGINEER'S ESTIMATES:
<br />The 2014 Solid Waste Master Plan prepared by Neel -Schaffer, Inc. estimated the Segment 2 Partial Closure
<br />and Landfill Gas Expansion project cost at $6,500,000.00 and the Segment 3 Cell 2 Expansion project cost
<br />at $4,505,000.00 for a total cost of $11,005,000.00 in 2014 dollars.
<br />On March 1, 2018, CDM Smith provided a 100 Percent Opinion of Probable Construction Cost for the
<br />project in the amount of $19,200,000.00 as included in Attachment 2. The Segment 2 Partial Closure and
<br />Landfill Gas Expansion project was estimated at a cost of $11,700,000.00, and the Segment 3 Cell 2
<br />Expansion project was estimated at a cost of $7,500,000.00. CDM Smith provided this estimate based on
<br />the material prices obtained from recognized suppliers and review of recent bids such as the St. Lucie
<br />County and Pinellas County expansion and closure projects.
<br />ENGINEER'S BID EVALUATION:
<br />On March 1, 2018, the Indian River County Purchasing Division provided a summary of the bid tabulation
<br />confirming that each of the bidders was responsive in submitting all of the required information in the bid
<br />documents. See Attachment 1 for the Bid Tabulation.
<br />On March 26, 2018, CDM Smith provided the evaluation of bids for this project as summarized below.
<br />• [�33 C��G�3�1 ��L�-33-
<br />Thalle Construction Company, Inc. $14,576,600.00 $1,457,660.00. $16,034,260.00
<br />West Construction, Inc. 121 $15,723,097.14 $1,572,309.71 $17,295,406.85
<br />Southeast Environmental Contracting, Inc. $16,858,000.00 1 $1,685,800.00 $18,543,800.00
<br />(1) Per CDM Smith, Thalle calculated the 10 percent contingency as 10 percent of the total bid, i.e., $1,619,600.00 for a total bid of
<br />$16,196,200.00, not as an additional 10 percent of the Base Bid Items 1-6. Therefore, the actual contingency is $1,457,660.00 and the
<br />Grand Total Base Bid for Items Nos. 1-7 is $16,034,260.00.
<br />(2) Per CDM Smith, West Construction had some minor calculation differences when taking the bid quantities times their unit bid prices.
<br />Therefore, CDM Smith reduced their Grand Total Base Bid Items No. 1-6 from $15,734,483.58 to $15,723,097.14 which is a minor
<br />difference of $11,386.44. The contingency was reduced accordingly for a Grand Total Base Bid Item Nos. 1-7 of $17,295,406.85.
