The building control officer (BCO) was not happy with the escape strategy for this single staircase dwelling being refurbished. I was asked to clarify it and prepare a logic. I inspected the building with the client. At my request the architect marked up the plans showing the protected areas and I prepared a logic for the escape which, for one fire scenario, involved an unusual route. This was accepted by the BCO. There was also a query about upgrading the fire resistance of thin timber panelled doors and I gave several options and copies of historic papers dealing with the issue.
