help - rsj for loft conversion

[mgibbons]

new to forum just went to order rsj for loft conversion and have realised that the architect and building inspector did not realise that the roof actually starts in 1st floor bedrooms (slightly sloped ceiling) so i dint know what im supposed to do if i put the rsjs where it says on the plans it will be sticking out of my roof, if i go by the original roofing plate i would have to remove the ceilings but im not sure how i would do that without making the roof collapse. HELP PLEASE ASAP (architect on his hols typically so cant contact him)

if the architect is away and there is no-one in his practice who can help (e.g. were the plans drawn up by a draughtsman or engineer?), consult the BCO.

Show him revised and accurate drawings and measurements and expain how they are different from what was used before.

Sounds to me like it is the architects fault, unless for some reason he was relying solely on information from you.

Someone must have designed the beam - I doubt it was the architect.

BCO = Building Control Officer

as far as I can see the same as we used to call a Building Inspector

Some of us still do - but they hate being called a BI, for some reason

It sounds like the existing wall plate is below the first floor ceiling line. You will need to speak to your structural engineer and ask him to design a cranked beam system.
