My last job (as an employee) was a strange one.

It started from a very informal handful of pictures. It's a case of "duplicate this" and modify as needed to add casters.
The project manager did a good job of getting all of the critical dimensions.
It seems like someone designed these to be as big as possible, while still fitting within the limits of 4 x 8 sheets of plywood.
It's a 47 1/2" square, with 32" high sides, one fixed shelf near the middle. It has in-set slab doors, locks with a "different than usual" retention and flush pulls.
Getting them where they need to go, might be a challenge. I heard that they might have to go through a single doorway. The shortest dimension is the height, at 36 1/4", so the casters and skirt may have to come off.

Hey CRG, you're retired...so it's not your problem.

This is the boon I was referring to earlier.

@Cheese that's exactly right. It would have to be done on-site anyway, so still not my problem, but I try not to do stuff like that to the driver. He is my friend after all. We've worked together for 16 years.
The project managers are supposed to be aware of such conditions, so we can adjust accordingly. The person who said that might be wrong though, we'll find out eventually.
