IBS Component In Use (Structural & Architectural)

Precast Hollow Core SlabPrefab Steel Roof




Precast Wall

Precast Beams

Precast Cornice & MouldingPrecast Staircase

Aluminium System Formwork

Speed Of Progress Of Work

Estimated at 1 month 1 floor for structure framing

Estimated at 1 month 1 floor for precision blockwork




Wall system (max 30%) - widely available in the market

Others Simplified Saving Construction Solution (max 20%) - standard

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

Precast Hollow Core Slab Costing ExamplePRECAST CONCRETEThe design, supply, delivery and

installation of precast component:-

4. IBS in contract management considerations

Ideas To Increase IBS Score

By increase usage of

Precast Hollow Core Slab

Precast Half SlabPrecast Waffle Slab

Precast Plank

Prefab Steel RoofSteel Structure

Precast Wall

Precast BeamsPrecast Columns

Precast Cornice & Moulding

Precast BalconyPrecast Staircase

Offsite Barbending

3D toilet module (POD)

System Formwork (metal / aluminium / plastic)

Construction Considerations

Heavy lifting crainage / tower crain



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
