Hi we have a builder booked in to remove an internal load bearing wall over a span of 3.2m. We didn't want nibs on the walls to keep them flat for appliances and he said that a 100mm bearing would be sufficient.
The wall supports approx 250 bricks for a small bathroom wall above and has 4 joists sitting directly on it. 2 from the bathroom and 2 from the back bedroom. All the other joists either run the full width of the house or rest on an existing doorway which will be bricked up. The RSJ will rest on the external cavity wall and an internal single brick wall both running at right angles to the wall being removed.
We have sent notice in to building control but I have just found out that 150mm is the recommended bearing.
Is 150mm mandatory or only a recomendation in certain circumstances. We're struggling for space and the nibs will ruin the layout of the new kicthen. My builder didn't seem to think it was a problem and he has also said he has spoken to building control who told him that calcs probably won't be required because of the type of work involved. Is he right or do you think I should get someone else in?
