hi,
I just received my structural calculations and building regs documents, everything seems fine.
I'm jut curious about one concept that I can't completely understand, mainly as a learning moment. the engineer wants a box frame as we're looking to completely remove the ground floor rear wall to create an open space with our new extension. that involves installing an RSJ in the foundation. obviously the RSJ will sit right under the existing first floor wall, which rests on the original foundation of the house.
how is that even possible? in order to install something in that foundation, you will have to remove the rear part of the foundation first. won't that simply destabilise the house? how is a beam installed in such cases?
