PPVC
WHAT IS PPVC
PPVC means a construction method whereby free-standing volumetric modules(complete with finishes for walls, floors and ceilings) are constructed and assembled inan accredited fabrication facility, in accordance with any accredited fabrication method,and then installed in a building under building works.
PRECAST FIT OUT PREFINISHED
CHARACTERISTICS OF PPVC SYSTEM
RC Walls– Comprises 90mm thick walls located on two long sides of modules
Floor slab –Comprises 130mm thick RC floor slabs spanning across the shorter span of modules on beams.
Balcony and AC
Ledge- Balcony/AC slab will be cantilever
Ceiling – RC ceiling flat slab of 70mm thick is provided
This PPVC system
developed by
Dragages
Singapore is
particularly
suited for
building projects
as it provides
robustness on the
structure and
enhanced durability.

PPVC LIFTING BEST PRACTICES
• 1866 modules
• Modules weigh between 18
tons and 32 tons
• 2 towers & 40 storeys high
REQUIREMENTS
PPVC LIFTING BEST PRACTICES
PPVC LIFTING BEST PRACTICES
• Documentation
(MS, Lifting Plan, RA)
• Plant & Equipment
• Competent Team
KEY FOCUS AREAS
PPVC LIFTING BEST PRACTICES
• PPVC Mobilisation and Installation
• Loading and Unloading of PPVC
RISK ASSESSMENT
PPVC LIFTING BEST PRACTICES
• PPVC Mobilization and Installation
• MS for Erection and Assembly of PPVC Carcass
METHOD STATEMENT
PPVC LIFTING BEST PRACTICES
LIFTING PLAN
• To ensure safe
lifting of PPVC
Modules
• Prepare and curb
risks associated
with lifting
• To ensure lifting
procedures are
informed to
relevant persons
PPVC LIFTING BEST PRACTICES
Gantry Crane
• 2 nos 30 ton
• 2 nos 20 ton (synchronized)
• Production Capacity
➢12 days per module
FIT OUT FACTORY
PPVC LIFTING BEST PRACTICES
PPVC STORAGE ON SITE
PPVC is stored
such that Crane
Operators can
fully see the load
without
obstruction while
lifting
PPVC LIFTING BEST PRACTICES
HIGH-CAPACITY TOWER CRANES (LIEBHERR)
• Brought in from Germany
specifically for the Canopy
Project
• SWL: 40 ton
• First time to use these types
of cranes for residential
projects due to PPVC
technology
• MOM type-approved
crane
• More expensive but is safer
to use especially for lifting
at higher heights
PPVC LIFTING BEST PRACTICES
HIGH-CAPACITY TOWER CRANES
(LIEBHERR)
• Easier to erect and
dismantle due to
monoblock design
• Lighter weight
compared to other
cranes of the same
capacity
• Hammer-head type
which is the fastest
type of tower crane
• Higher end crane
due to newer
technical equipment
PPVC LIFTING BEST PRACTICES
HIGH-CAPACITY TOWER CRANES
(LIEBHERR)
• Micro-move function for precise
positioning and speed ideal for
PPVC Installation
• Electronic Monitoring System
(EMS) allows to precisely delimit
the working area
PPVC LIFTING BEST PRACTICES
HIGH-CAPACITY TOWER CRANES
(LIEBHERR)
• Data logger function
PPVC LIFTING BEST PRACTICES
SELF-BALANCING LIFTING FRAME
A special lifting
frame was
designed, approved
and fabricated
specifically to
ensure safety during
the lifting and
installation of the
heavy modules
PPVC LIFTING BEST PRACTICES
• Each wire rope SWL is 5T
• Each pulley SWL 8T
SELF-BALANCING LIFTING FRAME
PPVC LIFTING BEST PRACTICES
SELF-BALANCING LIFTING FRAME
• Daily Inspection by Lifting Supervisor
• Monthly Inspection by Method Manager
• Magnetic Particle Inspection – 6 months
• Steel Wires are replaced by each 7 floor
lifting of module installation.

PPVC LIFTING BEST PRACTICES
Balanced Lift – Evenly spread load enables a balanced lifting.
Less manpower – Maximum of 2 riggers are enough to secure all the 12lifting hooks. (In conventional method tedious rigging work involved to balancethe load evenly by using additional chain blocks in all the hooking points).
Time saved – Easy to hook and faster. Ready to use.
Productivity- Improvement in the productivity and more modules are lifted.
Quality – High quality assured without any damage.
Compact storage - Does not occupy much space when not in use. Can bestored over an existing module.
Recycle and reuse - Can be detached and transferred to other similarprojects.
Zero Incidents - Ensures a complete safety during a lifting process.
