I totally agree that one has to know the circumstances very well to do fixed bid successfully. But one quibble on the Agile stuff: Agile is not a match for the contract if the client values contract negotiation over customer collaboration, as that's the opposite of one of the Agile values.

That way when the specific Tuesday in May arrives, you are most likely to have completed the pieces they most care about. And also have the flexibility to make tweaks if priorities change.
