Are building control aware of this work, as normally you would first need building control approval before doing such work on load bearing walls?
I ask since they may wish to see evidence of the calculations etc for sizing the RSJ.
You need to inform building control, who advised this is was not required, if you have altered the exterior of the porch you would also require planning permission.
Ok, if its a load baring wall and your changing the size of the steels it will need building control but not planning.
A 5 minute conversation to their building control team will confirm it either way, but if you continue and later find out it was required you could incur a significant fine for retrospective approval, which often gets picked up as part of conveyancing.
I am going to opt out, as I am not comfortable providing this detail without supporting information a building engineer has signed of on what your wishing to do.
I have opted out so another engineer may assist but it appear no other experts are comfortable with providing the information you require either, which I imagine is due to your works not being authorised by building control. If no experts pick this up over the week I can pass this over to customer services for a refund under our money back guarantee.
