7.2 Prefabricated Construction Systems adopted in Hong Kong

Drawback:TTighter and longer period of coordination are required toallow for structural design, construction planning,procurements and approval proceduresMMore time required in advance for production of precastelements until they can be accumulated to sufficientnumbers for delivery to site to start installation.Huge working space is required for the carrying out offabrication works. This is particularly critical under HongKong situation. Though most of the fabrication works arerecently carried out in casting yards in China, this willincrease the transportation cost by sea or on land.
