Structural Design Calculations for my House Extension

I had run my rough plans past a local structural engineer at an early design stage. Now I had planning permission it was time to call him back, formalise arrangements and talk though the calculations I needed for my BCO plans.

I planned to take out a load bearing wall and have a couple of support steels in my new build. To add further complications, I also had a well in my kitchen that would need capping off. We talked through all the calcs I needed. He then went away to draw up my structural plans.

Though I planned to do all the new build work myself, I really didn't fancy taking responsibility for removing a load bearing wall so I called in a local builder who has worked with my structural guy before, to talk through the wall removal and get a quote.
