Was at a site doing some R&D as to how we were going to put irrigation back together due to a portable building and its foundation being removed when I was approached by the site guy. He said that he'd noticed a new (3 months old) sidewalk was getting stains on it from the irrigation and asked if I could look at it. Since I already had that system's controller on the remote I fired up the suspect zone and water came gushing out from every crack within a minute. At about the same time the director over Operations/Maintenance just happened to come around a corner and witness the problem. He asked me how this could of occurred and I advised him that the sidewalk installation was never coordinated through our department and this was the first I'd known about the problem. Since then (three days ago) I have received personally four emails from this director regarding asphalt and concrete projects that will be undertaken prior to schools starting up on August 17th. He now believes that there is no reason that the "irrigation guys" should be cut out of the loop because they now fear that foundations may be undermined if problems like this keep happening. We'll see what happens and how long this lasts.
