Sorry yes the walls are gutted the cieling is not and the crawl is 3' to 6' a split between the two. The service is 100a and upgrading to 150a because an AC is being installed. The code is 2009. The service is overhead. Lighting provided already. Three ceiling fans, one vanity, one combo fan/light, one t8. I'm really just curious where I'm at with panel/meter, demo rough-in
I think you meant code edition is 2008. (I'm in Tn also)
It's too hard to give an estimate without seeing it and knowing your costs etc.
If you've wired many houses I would simply look at what it took to do a similar size house. Then because of extra difficulties such as removing wire and working with a closed ceiling, I would add that as extras to what a similar size new construction home would cost.
Not advocating a square foot price but if you've done enough of the same type houses you could get a square foot price then add some to that.
ie;
normal per sq ft = 7.00
difficulty factor = 2.00
New sq ft price = 9.00
This is just an example and the numbers are just made up.
Probably, other than T&M, if you could get a count on each device, whether 120V or 240V, higher amp draw devices (40, 50, 60A), amount of wire, etc. IOW, do a take off, that would be the best.
Figure time to do it and get your price for materials, add you MU & profit, then price it!
