Sustainable Construction - Building & Construction Authority

The Approach:
Analyse the risk of fire starting in building.
The Solution:
Sustainable Construction -
Check the effectiveness of the automated fire sprinkler system
Take measures to increase the reliability of the automated fire sprinkler system
Study the fire growth and compartment fire conditions, taking into consideration
the fire fighters intervention
In terms of structural performance, allow:
Load-carrying mechanisms for beams and slabs in a structural frame to include
membrane action
Load redistribution from members
The performance-based design allows most of the steel floor beams to be unprotected while
maintaining the building’s structural stability in a fire.
This enabled the bare steel structure to be expressed and enabled cost-effective construction of
the building.
The performance-based solution also allowed the two blocks to face each other with no additional
fixed fire protection systems.
Only selected beams were fire rated. These key steel beams were chosen to be fire-rated for
enhanced safety factor and they generally occur in critical areas like corners of the building or
in long span areas.
