I used to follow the HAAS Tip of the Day (lately its just sales hype) on
YouTube and they had an episode where they discussed just such issues.
I forklift going by on the shop floor would throw all the parts out of
spec.  (They were chasing a lot tighter tolerance than a saw.)  The site
wound up cutting out the floor and placing all their machines on
isolated poured in place concrete bases.

In another shop the machine was running on blocks on a compacted dirt
floor and meeting tolerance every time.
