In the realm of structural engineering, construction, foundation design, what is "crs" when talking about piles/posts? Is it an abbreviation? Does it refer to some sort of size?

"CRS" is an abreviation for "Centers".
So, for example the statement "Deck Joist @ 400mm crs" means "at 400mm centers", i.e. that the centreline of the joists should be 400mm apart.
If you were to measure the gap between the joists, it would be less than 400mm, due to the thickness of the joist itself.
