14 SPECULATIVE BUILDINGS

This is not, relevant to Mezzanine Floors or High Racked
Storage Areas since it is extremely unlikely that such a
building would be built speculatively.
Where designers are called upon to design systems for
buildings where details of the occupancy, use, sprinklers
etc. are unavailable, the following minimum criteria should
be used for design.
14.1 4.5m x 4.5m sprinklered fire (see Sections 5.3 and
5.4 for heat output).
14.2 Clear layer to eaves level or 500mm above the top of
the highest opening.
14.3 Replacement air not available from doors and windows.
14.4 Smoke compartments to be limited to 2000m² max.
