This is a bit of a silly assertion isn't it? Of course one cannot confuse Safety with profitability. But, people do get hurt, but in different ways. Unprofitable plants are not funny to the companies that build them. Neither are losses due to unforeseen extra costs and delays, etc. That is why there are Liquidated Damages clauses. I have seen them used on projects where there was a clear performance problem.
Finally, companies have their reputations to think about. I think that SAIC or any EPCM, is a cut above doing what you are saying.
