Direct Purchase of Certain PC South Equipment <br /> The PC South project includes several major pieces of equipment that the County may <br /> directly purchase to avoid payment of sales tax. The costs are summarized in Table 3. <br /> Table 3— Direct Purchase Equipment Costs <br /> Direct Corresponding <br /> Item Description Vendor Purchase Attachment <br /> Amount <br /> 1 South Relief Canal pumps Xylem/Flygt $470,806.00 Attachment J <br /> and controls stem <br /> (W 2 Pump Station No. 1 Xlyem/Flygt $212,574.00 Attachment J <br /> pumps and controls stem <br /> Self-cleaning bar screen Duperon <br /> 3 for the South Relief Canal Corporation $191,000.00 Attachment K <br /> pump station <br /> 4 Self-cleaning harvest rake To Be $200,000 N/A <br /> for PC South Determined estimated <br /> TOTAL DIRECT PURCHASE PRICE $1,074,380.00 <br /> Direct purchasing the above equipment will result in an estimated state sales tax <br /> savings of $75,206.60. The manufacturers for the first three items were selected <br /> because similar equipment from these manufacturers is installed at Egret Marsh <br /> (Xylem/Flygt and Duperon) and PC Main Screening System (Duperon). The similar <br /> equipment works properly and staff is intimately familiar with its operation. <br /> Standardization of major equipment will increase the efficiency of staff operational, <br /> maintenance, and repair efforts. <br /> Another direct purchase item was also considered: a Duperon 2 mm diameter <br /> perforated plate screen ($432,000) for the PC South headworks structure. The <br /> perforated plate was intended to remove small particles pumped into the facility from the <br /> South Relief Canal. However, staff does not believe the perforated plate's benefit <br /> justifies its cost. Staff will delete the perforated plate from the project and redesign the <br /> headworks structure, maximizing its ability to settle solids for periodic removal by <br /> vacuum truck. <br /> 5 <br /> F:\Public Works\KeithM\Stormwater Projects\PC South Construction\Agenda Items\Agenda-PC South Recommendation of Bid 181 <br /> Award for Construction.doc <br />
