Brian Lewis <br />August 23, 2017 <br />Page 2 <br />3 feet at wellhead riser and maximum trench depth will be 16 feet at a 3 to 5 percent slope to allow <br />condensate to drain back into the waste. Solid lateral piping for both the collector and vacuum lines <br />will be bedded with 6- inches of compacted sand. The vacuum lateral for HC -1701N will tie into the <br />existing riser at HP -14 and the vacuum lateral for HC -1701S will tie into the existing riser at EW -6. <br />SCS -FS will install new 2 -inch Landtec wellheads, flex hose and rubber couplings to connect the <br />horizontal collectors to the vacuum laterals. All trench spoils will be backfilled into the trench or <br />deposited on the active working face. <br />Task Two: Abandonment of Existing Vertical and Horizontal <br />Collectors <br />SCS -FS will provide labor, equipment and materials to abandon the following vertical and horizontal <br />collectors in the active cell: <br />EW -6, EW -7, EW -8, A-2, A-3, HP -9, HP -10, HP -11, HP -12, HP -13, HP -14 <br />All PVC wells will be capped with schedule 80 PVC caps using PVC cement and all HDPE lines will <br />be capped with HDPE caps using butt or electrofusion equipment (this includes gas well, vacuum <br />line and air or force main piping as applicable at each location). The vacuum lateral riser at well <br />EW -6 and collector HP -14 will be left as vacuum risers and capped with flange adapters and blind <br />flanges. <br />Task Three: As Built Survey <br />If requested, SCS -FS will provide a surveyor to collect an As -built survey of the new horizontal <br />collectors and vacuum lateral piping. This work will be performed on a time and materials basis <br />using our current MSA rates and standard mark-ups. <br />COMPENSATION <br />Task One — SCS will provide the services described in Task One for a lump sum fee of $55,000. <br />Task Two — SCS will provide the services described in Task Two for a lump sum fee of $14,500. <br />Task Three — Time and Materials. <br />Total Lump Sum Cost — Two (2) Tasks combined is a lump sum fee of $69,500. <br />Thank you for the opportunity to prepare this proposal; we welcome the chance to provide our <br />services to Republic Services.
