A reporter provides structural ‘back-up’ to architects who design houses, and he has not experienced any architect being more specific than noting on a drawing ‘ties at 1200 c/c’, normally related to connecting floors to walls. The same architects get less costly structural support from engineers who do less drawing work, but issue A4 sheets of standard details. The reporter is concerned that until this profession of structural engineers raises its standards, there will be troubles.
