components MS1064; repetition; 3D components; etc
Structural system
Points are awarded based structural system used
Allocation based on % floor area that utilises the structural system
Sub-structure works (elements) are not taken into account in the
calculation e.g. Piling, ground beam, ground slab, underground car parketc)
The construction area includes car porch but excluding driveway, apron
and landscaped areas
For structural system using Load Bearing wall, whether precast or in-situ
the factor can be determined from the table by treating the wall as widecolumn
The factor for tunnel formwork system is 0.6
This is for structural without floor. For other structural systems not
mentioned in the table please refer to CIDB for the factor

Construction Considerations

Sr Yeap Soon Kiat Dec 2010 Kuala Lumpur yskiat@yahoo com Page | 18
More full time crainage
Different lifting contraption
Walky-talky
Sub-contracting
Limited IBS system / brands
Lack of connection / integration of IBS components
Required a lot of floor to floor & services by services planning & coordination
Allow for starter bars or connectors
Cost Considerations
Savings on formwork
Savings on timber scaffolding
Savings on construction period
Lower labor content
Less wastage
Higher cost of IBS
High initial / setup cost of IBS
Less competitive tender price
Need high tech contractors / sub-contractors
Alteration / Renovation Consideration
Difficult to accommodate, needs to be pre-planned upfront
Requires hacking
Structural elements cannot be hacked
