straightedge,
You're asking for a heap o'trouble if you provide that house with a 200 Amp service. I am aware of two similar houses where the electrical contractor provided a 200A service and there was severe flickering on lights when motor loads kicked in. Even if the load calcs say 200A is adequate (and I'd really like to see those calcs of you're willing to share them), a 400A lateral from the utility will provide much better voltage support and reduce flickering.
Keep in mind that the owners of a 5,000+ SF house aren't going to tolerate pronounced flicker when the AC conpressor comes on...
Also, I didn't see a subpanel in the bid, or a telephone/CATV distribution panel. Seems odd to me to NOT include a subpanel is a house that large. And the distribution panel seems essential to me--won't the place have 20+ phone jacks and almost as many CATV outlets? How about a LAN patch panel?
Did you do the electrical design for this job, or are you bidding the usual inadequate architect's electrical design page of the print? If the latter, if you get the job, you may well be the fall guy when the homeowner finds out that thay got a tract-home quality electrical system in their 5,000 SF house.
Good luck.
Cliff
