Info

Recent Achievements of Hong Kong’sPrefabricated Technology• Previous defects such as leakage problems have beenimproved• Application diversified to other forms of construction• Capable to apply to rather complicate-shaped buildings• Incorporation of other advanced technology in theconstruction (such as use with mechanical form/tensioned elements)• Generally mastering of skill and growing popular
Future Trend in the application ofPrefabricated Technology in Hong Kong1. To increase the use of prefabrication for more structuralelements such as for beam, column or load bearing wall2. Use more modulated elements or plug-in units3. Use more for architectural or decorative elements4. Incorporation of other composite elements in the designsuch as using at the same time with structural steel5. Apply prefabrication more to medium-rise buildings withmore standardized structural items6. Improve the supply chain management to makeproduction more efficient and economical
