How about "assembled *and tested*"?  Once you have the infrastructure
on place, the added cost of making a few more rockets on Mars and trying
them out is rather small.  One could get up to at least the standards that
rockets made on Earth live up to before humans board them.

Thing is, any venture seriously proposing one-way trips as a cost saving
measure, is going to reject such notions out of hand.  They're going for
flags and footprints.
