I've no experience of building a tower block, but do know when doing some
major works on this house, the BI insisted in seeing some aspects of
things (like RSJ pads) before they were plastered over.

Exactly the same here, when I had an RSJ put in. They want sufficient
engineering bricks on top of the breeze block pillars.
