Application:
Shui On was the first main contractor to apply this construction technique at a Hong Kong Housing Authority (HKHA) housing project (Tin Yiu Estate Phase III site) back in 1990. HKHA approved the design of precast facade and specified its use in the typical floor construction of most of its subsequent projects.

Description:
The external facade walls are precast with window frames cast in and can be produced on site or in the factory.
 

Features and benefits:

• Uses precast facade to accelerate the repetitive typical floor construction for high-rise buildings.
• Achieves better quality as compared with the in-situ facade produced by the timber shuttering method.
• Ensures better waterproofing since the window frame is cast in with the precast facade.
