On 1 job a few years ago, the GC was getting quite annoyed with the constant revisions on a machine shop layout and wanted to get his floor boxes located once and for all.
He had cardboard boxes cut out to the exact size and shape of the equipment the day that the Owner came out with his latest layout.
Once all of the equipment was laid out, the GC spray painted the locations on the floor and told everyone that ANY change from that day forward would cost money.
Amazingly there were no further revisions to the floor plans.
