I would think that if you wrote the estimate in four different estimating softwares, then you would get four different repair amounts.
You could probably have four different estimators write the same job with the same software and get four different amounts, but that is a different issue.
If you actually did the job and tracked all of your costs incurred to do the job, and you would get a fifth amount, much less than any of the four above prices.
If you give that list of incurred costs to four different fire restoration contractors, you will get four more different estimate amounts. These four might or might not be more than the four that came out of the estimating programs the first time. Here the difference is obvious, it is what the contractor want to make for doing a job. I believe Mr. Postava has stated, and I heartily agree, that this is the largest cause of price difference between contractors. There is no way for a repair database to anticipate, or even track, what a contractor wants to make on a job. This is the crux of the problem of compiling an insurance repair database, which I have done.
Which of these nine prices is the correct one? Of course, it is the one that gets the insured's property back into the state it was before the loss. One that the carrier will pay and the contractor will accept. Which of the eight possibilites (obviously it is not the incurred costs price) would this be? That answer would probably be different for each insured.
There does not exist a insurance repair database, that I am aware of, that can tell you what something should cost in a certain town on a certain day. If you cannot figure out what something costs, you cannot figure what someone wants to charge for it.
While it would be possible to figure costs for an operation in a certain place on today's date, it still would not anticipate what the various contractors would charge for that operation, so it would not reflect market costs.
Do I think that prices in some database are artificially low? Yes. Do the tools to prove this exist? No.
It almost seems a miracle any claim gets closed.
And over the course of my twenty one years in the industry, I have met many wealthy insurance repair contractors. Many more that I have met wealthy cat adjusters. The contractors seem to do alright if the prices are artificially low. Look at the marketing BalFore does and tell me insurance contractors are underpaid. That overhead gets covered somewhere.
But that's just my opinion, I could be wrong.
