We are beginning a install in a new condo complex (22 duplex units in across about 15 acres or so). At the moment, nothing has been done (not even the streets). So far the water and sewer lines have been layed and backfilled, and power and telephone ditches have been dug. These ditches run alongside all the new roads. The GC want to backfill the ditches up to the 2' level and let us lay our mainline in them. While I understand that it might save time and money now, I'm worried about the roadcrews destroying them and burying the valveboxes. We are going to go for it, but I'm getting the feeling that I'm going to have a nightmare on my hands.
