12. Engineering Approach : A Brief Introduction Construction industry in the Hong Kong Special
Administrative Region (HKSAR) is developing rapidly.
There are new design features such as atrium buildings which were built and found in large scale development projects including shopping centres.
Green/Sustainable Buildings with glass façade, super tall buildings are examples.

Many highrise buildings packed together

Fire safety features must be designed to the satisfaction of the local authorities as it is a key area to be considered seriously.
This topic has drawn public attention as a consequence to serious accidental fires occurred recently.
People started to aware of the hidden problem on fire safety and ask the question:
Whether they are sufficiently protected while staying inside a building ?

The Big Garley Building Fire 1996
Accidental fire
Bus Fire: Burnt completely within 10 minutes
Solar heat cannot enter.
But in an accidental fire, heat generated by the fire would be trapped inside and time to flashover would be shortened.
Very big fire would be resulted in burning almost all combustibles.

may not be sufficient for providing fire safety in some buildings with special designs.

How can those codes apply to ultra highrise building?
Might be OK for these !

Figure 1: Process for approving fire safety designs
There is no engineering performance-based fire codes (EPBFC) yet.
The authorities (i.e. BD) accepted that “engineering approach” for passive fire safety design since 1998.
