Wrong approach. At the first error, shut it down, call the supplier of the model, tell him you're back-charging him for down-time until he properly transmits the files and all their supporting data. It's part of our standard contract, you supply us with everything we need to use your files, or you pay us, by the hour, to sit around waiting on you to come up with a solution.
You are making a wild and inaccurate assumption: these are not models supplied by vendors, these are models and drawings supplied by co-consultants; and like it or not, we are not in a position to demand, we must request things in a professional manner. If we took an arrogant, high and mighty stance there is a real possibility we might enjoy a smaller piece of the pie for sporting "attitude".
Well one guy's high and mighty is another's intelligent business practice. Are you being paid by the hour or the job??
If it's by the hour, you'll be making a profit, but your client is getting screwed by somebody else's errors. As a client, I want to know when my money is being wasted, and I really appreciate a consultant when he points it out, wouldn't you?
If it's by the job, you're spending your profit on somebody else's errors. Profit that you must attempt to recover somehow, back-charges, cutting corners, future price increases, somehow sone where it's gotta be paid for. As a client, I can appreciate the situation, and I really would prefer you not to cut corners, nor would I like to spend more money on the next job because of somebody else's errors. Back-charges are a PITB, but the only reasonable way to place the financial burden where it belongs. The sooner it happens the cheaper it is.
Either way, as a client, my costs are cut, and the product remains cost effective.
Call it arrogant if you like, but I prefer to be profitable.

As a contractor (co-consultant) we get paid by the job, fixed price, one fee whether it takes a week or a year. Our standard contract, provides details for acceptable deliverables, and direction for resolution of non-compliance. Both the client, and other consultants are aware of these requirements to achieve our common goals. Our profits will not be determined by the performance (or rather non-performance) of other contractors. The financial burden of his errors will be carried by him alone.
