I recently submitted steel beam calculations from a structural engineer to my local authority. Within 72 hours they came around and inspected, verbally confirmed all OK and builder continued work. 7 days later I received that the structural calculations are unsatisfactory. I've been asked to 'provide labelled plan cross section drawings/sketches for the whole property to enable checking and verifying the adopted loadings. Because the sketch shown in the design calculations is inadequate.
It seems crazy to me and I'm unsure how to proceed
