Delays have been my frustration as well lately. Was having a garage/ shop built and was told it would be done February 1, then February 8, then February 12. Finally lost it as I was spending days at home waiting for the electrician to do a walk through on the layout, then a second walk through, then I had to be there to let him in the house and each day he either would not show up or showed up for an hour when he was suppose to work for 8 hours and I was not able to be at my work to actually help my customers. Yesterday we FINALLY got it turned over to us, feels good even with me having to do a pile of little things to finish it at least it is in my hands.
Hopefully they get the water issue solved soon for you so you can move ahead!
