Safety warning issued over transfer slabs

The Building Safety Regulator has issued a warning over a “potential structural safety issue affecting reinforced concrete buildings constructed with ‘transfer slabs’.”
A transfer slab is a floor arrangement where a column sits on top of a slab, but does not have a supporting column directly beneath it. The slab acts to support the load from the column and spreads it to the supporting columns below.
The design has been used for 25 years in the UK often in mixed use scheme
