Thanks Sevver, for fast response. I will have all utilities marked, but PC even excluded damage to overhead electrical wires out by the street, (ours are not underground). How do I, diplomatically, address these issues? Moreover, can't we poke rods in the ground to check for underground boulders, etc?

HELP!! The contract even states that we have to look to manufacturer's warranty for all items purchased. Is than routine? There is no mention of PC warranting installation or are anything else. In fact, it states that the sole warranty is what is provided by the wholesalers. Should PC warrant their work and or products? If so, what is a reasonable warranty on a pool installation as described above?
