I couldn't find any ref to 'beams' but I would expect RSJs (rolled steel joists) to feature at ceiling level and I can't see it.
In 1980 I organised the total refurb of a terraced house which involved demolition of 12' of a 15' dividing wall between two ground floor rooms. An RSJ of a specific size was required and it had to be fireproofed.
I can see nothing similar anywhere mentioned in the plans for the internal wall demolition done on these two properties.

If you look at the plan on page 15 all the beams supporting the upper floor radiate out from that central column to the walls. The section on the extreme right of that page mentions them and what size they should be.
