load calculations

[hallnc]

For those of you who do load calculation...
Just wondering if you charge extra to do a load calculation? If it's something that you can sell to a customer or do you just add it in when you do an installation?

I have been in business for six years and just now came across where an inspector is requesting a loa calcualtion be done. I was looking into purchasing a program for this but just wondering if it's something that customers would really be interested in knowing and if it's to be sold as an additional product or included in price of any installations?

I do one for every job i sell
have never done one by request (for calc without the install)

does not mean i wouldnt and for a nice fee i would do them all day

it would have to be a real nice fee though
