Floor fire resistance
« on: February 07, 2020, 05:43:09 PM »
Conversion of an old office building to hotel use requires the floors to have 90min fire resistance as the building height is just over the magical 18m by about 2.5m. No sprinklers. Now the fire engineer has proposed 90min protection for the ground and top floors leaving the intermediate bedroom floors at 60min. The bedroom floors have been fitted with 60min ceilings in error. The key mitigation on offer is the introduction of a third fire escape stair. Am I not right in saying that the primary purpose of increasing fire resistance with increasing building height is to ensure structural stability to permit search and rescue?
