Thanks very much for the reply!With the cost of materials changing almost daily, it is impractical to bid a job at all.
I have been quoting a price to wire a house by using the square footage to calculate labor cost. Then I price out materials and mark them up accordingly. The quote is good for three or four days. After that time frame I must check material pricing and availability again. I tell my customers that if they want to lock in material pricing, they must prepay for materials. Once I receive a check I will order the materials for their job.
Availability of materials have been problematic also.
i don’t think pricing by opening is going to work any better than a square foot price since the “wild card“ is the material pricing.
THIS^^^^^ This way you can quickly update pricing for every nut/bolt of material in assembliesuse assembly pricing. You build assemblies for each item i.e. receptacle, switch banks, GFI receps, etc. You need an assembly for everything in the house, and all of your switch combinations. Its far easier in software. When I first started pricing this way I spent a lot of time building custom Excel spreadsheets that pretty well covered me for the type of residential work I was doing at the time. I use Conest Intellibid now and its a bit easier.
20 years ago, I bought this book and it was a great starting point.
