Hello, I would like to ask for some information from you all. I am relativly new to the industry and primarily do res and light commercial. I have an option to wire a new home upwards of 8500 sq feet. Most everything around here these days is 1/3 of that. just wondering if most of you bid based on a sq foot formula or try to get a speced out fixture list? or go with something like wall hole and ceiling holes plus fixtures as the customer specs them. I would really like to be competative in this but need a little advice on the bidding. don't want ot find out that i got the job yet was missing the last bid by 12k. thanks

Dump the sq. ft. approach and put in the extra time required to figure p/ opening.
Assuming something that size can only be custom,get working price from plans and then talk to the h/o.Document all changes,and note that price is pre
'walk through'.After going through every room,etc. you'll all be on the same page and your numbers will be accurate.

thankyou for the reply. right now it's in the blue print stage and still working on a start date.....potentially. I had a heads up from the GC and said he was going to be asking for bids soon.
