The water main at STA 14+60, 24+25 and 10+50 (17th Street) <br />was redirected from the original alignment to avoid irremovable obstructions, <br />including an existing stormdrains and active water lines (cylinder main). Also, <br />various unforeseen obstructions were found, which needed to be removed. During <br />the installation process, existing buried concrete pavement was encountered. The <br />material was more difficult to remove then originally proposed and required <br />additional saw cutting or breaking prior to removal. The export of the spoils was <br />hauled to a different plant for further processing and disposal. Additional import <br />material (sand and aggregate base) was needed to fill the void. Other <br />miscellaneous repairs include unmarked sewer laterals, water services and traffic <br />signal conduit. <br />The change order provides compensation for delays associated with production <br />loss. A prior approval was granted on January 6, 2014. <br />(PC0#26;27,28,30,31,32,35,36,37,38,39,40,45,46,48,49,51,54,56,57,58,59,60,61,63,66,67,68,69,70, <br />72,74,76,77,78 &79). <br />FINAL COST $307,487.98 <br />
