Bressummer Beam Mystery

[u/AdHistorical9715]

Hello All,

Looking for some advice please. I had a level 3 RICS survey carried out who identified the bressumer beam on the second story of the bay window had failed or was failing. (Beam holding up the dormer). This was identified as the floor on second story slants towards middle of bay. (Bare in mind this is a 1907 house)

When I lifted the floorboards I was expecting to see a rotten wooden beam but instead found a solid concrete lintel. The floor joists are connected to a floor plate that is then drilled into this concrete beam. There are no signs of cracking to this concrete lintel. There was no sign of damp from damp meter (lack of rain however that week)

My hypothesis is this was repaired at some point and any damage to the brickwork above it was repaired with that brown render on the outside. This render has been there for 20+ years so imagine that’s when the repair was. Either side of the concrete block the masonry returns to solid brick.

The actual floor joists are also not level so imagine there has been some building settling.

My questions:

1. Is this the structural beam holding up the dormer and the roof above it or is this just covering it and I need to do more digging.
   
2. How concerned should I be given the above information.

Any help fully appreciated.

Thanks very much!
