Hi all - I'm currently having a kitchen extension built, and due to the pandemic and a variety of other issues it's fallen to me to kind of manage the thing. A long story short: I'm knocking through two walls and was recommended a structural engineer by my building inspector. They came to site, measured up and have sent me and the builder a long doc which includes a diagram of the beams and how they are to connect and a bunch of pages with loads of complex calculations. The builder has taken this to a fabricator as essentially the beams need to be connected, so the right holes and a bracket need to be made, but he's complained the structural drawings have no actual measurements on them. The engineer has come back and said it's not his job to do measurements and in 1500+ jobs he's never had to do that, and I have a stalemate. Of course I'm in the middle copping it from both sides when I have no idea who's at fault. To me it does seem odd not to have measurements, but the engineer states that's the job of the fabricator and his job is to worry about loads. When I asked if the measurements affect loads he said yes but not enough to worry about. Can anyone help me shed some light on this? Thanks!
