DNH was instructed to remove the bypass pump that was installed over the top of the holes and to excavate both areas to determine the cause.

I arrived back on site at 12:15 pm and found a hole about 4' in diameter under By-pass #1 (see photo), I instructed the contractor to remove By-pass pump #1 and to excavate and find the problem, I notified the Project PM of my findings at 12:30 pm, At 3:30 pm I returned to the site and found that the 30" DI force/gravity main had a 3" hole on top of the bell connection, While determining a resolution I noticed that another area about 8' south showed bubbles coming out of the ground, I requested that the contractor investigate this issue and found that a 24" DI spool piece of pipe connecting a 30" plug valve to a tee had also rotted away from raw sewage gases, I notified the Project PM of these new findings at 3:45, I remained on site until the contractor temporarily sealed both holes, Fred Sexton DRAFT Agenda Item No, 16C2 April 13, 2010 Page 60f6 o CORPORATE OFFICE 33IlOTRAVI5POINTERD,S\.lITEA.
