Change overall depth of sand for ballasting between the primary and secondary liners, from 25" to 18". <br />This change accounts for credit to delete 7" of imported ballast sand, and credit for 7" of excavation to <br />subgrade. <br />2. Change subgrade and liner base to add 3" of sand bedding and 6" of suitable native soil placed below the <br />secondary liner. This change adds back 3" of imported sand; adds on site transport and placing of 6" of <br />native soil; and adds 9" of excavation below subgrade in Item 1 above. <br />3. Remove the bid plan design for `ballast piping. This change will credit all work to provide and install <br />ballast piping, filled with flowable grout, and welded strapping to the top liner. <br />4. Add 'ballast trenches' to the primary liner per. This work requires shaping trenches in the ballast sand; <br />installing the liner within the shaped trenches; installing sand into the lined trenches; and then extrusion <br />welding a liner over the top of these sand filled areas. <br />5. Add 924' of 6" asphalt berms to the composting facility to match changes in drawing Sheet C6. <br />The attached cost breakdown sheets incorporate the changes noted above and are organized to separate the work <br />in a manner that is clear for review. <br />The total cost of the change order is listed below and broken down on the attached spreadsheets. <br />Sheet 01 <br />$(63,263.15) <br />Sheet 02 <br />$ 69,368.55 <br />Sheet 03 <br />$ 16,573.61 <br />Sheet 04 <br />$ 14,220.36 <br />Sheet 05 <br />$ 12,360.00 <br />Change Order Total: S 49,259.37 <br />Page 1 of 2 <br />
