Construction noise

The CT scanner below my office was removed a couple of weeks ago, and now they’re doing renovations on the room getting it ready for a new CT scanner. A few days ago they were doing some drilling through cement or something. Now it’s some kind of repetitive hammering noise. Floor work or something perhaps. I don’t know what they’re doing down there, but it’s loud and rattling my brain.

I think I shall be leaving work early today so I can escape this racket.
