We are shortly starting a loft conversion and the plans show a number of Steel UB's (on 15mm steel plates instead of Padstones). The steels are supported on the top of the wall under the hipped roof (hipped on all 4 sides).
Is it OK to support the steels on the specified steel plates on top of the existing wooden wall plates (100x75 approx)- or do I somehow need to remove a 300 mm section of wall plate and replace with engineering brick?
Thanks for any advice
