A revised plan was issued showing the height of wall to be <br />based upon finish elevations which were not shown on the original plan, requiring an <br />extra course of block to be constructed along 257 LF of soundwall. (PCO #06) A <br />prior approval was granted for this work on July 15, 2013. <br />AGREED. COST $ 1,698 <br />2. While potholing utilities for the new 12" and 8" water mains, an AT &T duct bank was <br />encountered in the trench line at two locations. The duct bank is 84" to the bottom, <br />with the top being 36" from the proposed finished surface. These elevations do not <br />permit the new 12" water main to be installed over the top of the duct bank and <br />therefore must be installed under it. Due to the proximity of a Metropolitan Water <br />District 36" water line, a vertical offset must be constructed at each location to <br />enable the installation of the proposed water mains under the AT &T duct bank.(PCO <br />#08) A prior approval was granted for this work on June 18, 2013. <br />AGREED COST $ 56,700 <br />
