Figure 2: PPVC Modularisation
Water-proofing works are carried out in the fit-out
factory at the wet areas; followed by water ponding
tests to check for water tightness. The PPVC
modules for each residential unit were also checked
for trial fitting in the fit-out factory to ensure that the
adjoining modules were well matched before being
delivered to site for final installation.
On site, upon installation of the PPVC modules,
the adjoining PPVC modules’ walls were joined

together with in-situ high-strength grout - resulting
in composite structure walls. These PPVC modules
were also connected to the balance cast in-situ
floor structures and lift core & storey shelter
walls to derive the tower lateral-load resisting
mechanism for wind load. For this project, the
total duration of the PPVC module installation was
approximately 12 months; the average floor cycle
time was six to nine days. The first two to three
