3.2 CLASSIFICATION OF OCCUPANCY & HAZARD OF CONTENTS
The ‘Occupancy Classification’ and ‘Hazard of Contents’ rating for each part of the development need be developed with consideration provided to the Hazard of Contents proposed.
This assessment shall in turn determine the extent of fire separation and protection required for specific hazardous areas throughout the development. The ‘Occupancy Classification’ and ‘Hazard of Contents’ rating for each part of the development can be described as identified within Table below.
This assessment occurs in accordance with the applicable provisions of the QCD Fire Safety Guidelines Rev2015.
Table below gives the occupancy and hazard classification for the proposed Building.

3.3 OCCUPANT LOAD
Calculation of the ‘Occupant Load’ is necessary to ensure the provision of adequate exit capacity for each floor and part of a proposed development or refurbishment.
The calculation need be performed in accordance with the applicable requirements of NFPA 101 – 2018 utilising the ‘occupant load factors’ specified therein for the different occupancy classifications.
Whilst the final occupant load capacities shall be determined as each of the room layouts are finalised, an adequate amount of egress width from each level need be provided to accommodate the proposed occupancy load.
Table below provides the Occupant Load Calculations for the proposed Apartment building.
