(2) The development standards applicable to such development include the requirements that on completion of the building work:
(a) if the building work involves the reconfiguration of any internal part of the building (being a part that is to be occupied)—the building will contain measures that are adequate, in the event of fire, to facilitate the safe egress of persons from the reconfigured part of the building, and
(b) the fire protection and structural capacity of the building will not be reduced.
(3) That requirement assumes that the building work is carried out in accordance with the plans and specifications to which the complying development certificate relates and any conditions to which the complying development certificate is subject.
