Bco git

[ETC]

First things first:

Anyone who installs an UVHWS needs to be competent. His/or her ID card will prove this to your BCO.

Secondly:

Check with your local British Gypsum representative - a standard first floor construction will - in my opinion - not give fire resistance to steelwork within the floor void. I would not accept this argument unless evidence is provided by British Gypsum and to date I have never received this - structural steel within a floor void should be painted with intumescent paint - I can of course be persuaded otherwise.

Let's go back.

Red oxide gives no protection.

Self applied fire paint works as well as professionally done. You do need to prove the thickness.

Not all steels need protection if very chunky.

How much is exposed?

Lengthwise

Cross section.

There are several means of achieving this.

Bco has done an hour on fire. I've done a serious course and argued on such several times. I might have forgotten of course.

The bco never admitted to being wrong, but found some getout. Same result.

Is it behind a ceiling , as mentioned? Cables are a potential source of ignition not of conflagration.

 

I assume you'd like to say: no further protection is required.

30 minutes FR required to structural steel in a house.

Lots of stuff here .

Remember bco has called this irrespective of his ‘knowledge ‘ ( or lack of )

Steels are about 350% over spec  ( as SE told me ) so we can safely say “ chunky “ .

How much is exposed ? Depends on which steel . Worst case 2 faces I.e the flat underside and 1 web .

The steel does not support walls or roof etc - purely exists for stairwell .

Above 30 min fire rated ceiling . No cables ( only low voltage lighting anyway ) cross the steel . Light cables go to perimeter lighting ring I.e not back to CU and hence across the steels .

Sounds to me as if that needs no further treatment.  What is behind the ceiling that might burn?

I would need to know the steel section reference.

 

I'd be cheeky and ask bco to answer the query from your fire engineer: what risk he perceives (where is the fuel behind the ceiling and the likely ignition.

 

Given the HP/A why does he think it needs more protection.?

Nothing . Beam and block !

I’m unlikely to antagonise my bco further !!!
