THis happened to the ground floor of a hospital in Cardiff
that I once worked at.

The histology lab on the ground floor (suspended timber,
being an old victorian building) kept all its glass slides
in special slide filing cabinets which when full were *heavy*.
One morning the lab staff came in and the cabinets were only
half height, the lower half having gone through the floor
into the crawl space.

Woodworm was soon diagnosed by the lab staff !.
