Allard, from what my sources inside the MDA tell me about the incessant (and incessantly false) claims of fraud, waste, and abuse by those who came out on the losing end of various prime/sub relationships, and my own experience with same. It's gotten to the point where any government acquisition program includes on their schedule enough time to allow the losing bidders (or, in many cases, NON-bidders) to protest the contract award decision before starting work on the task.
Please note that he's claiming that as a SUB-contractor, he was responsible for verifying that other contractors were doing their jobs. The government doesn't hand that tasking out to anyone.
