1 IBS SCORING IN MALAYSIA HOW CAN CIDB AND INDUSTRY PLAYERS WORK HAND IN HAND TO PROMOTE USAGE OF IBS IBS SCORING SYSTEM & CASE STUDY 1

2 CONTENT : 1) IBS SCORING SYSTEM 2) CASE STUDY 1 RESIDENTIAL 3) CASE STUDY 2 NON-RESIDENTIAL 4) FURTHER ENHANCEMENT TO IBS SCORE SYSTEM 5) CONCLUSION 2

3 1. IBS Scoring System IBS Score First Published : January 2005 First Revision : April 2010 Objective :- To provide a systematic and structured assessment system to measure the usage of IBS in a consistent way. 3

4 2. Emphasis of IBS Scoring System Setia Precast Sdn Bhd - The use of fabricated and precast components. - Off-site production of components - The use of standardised components - Repeatability - Modular Coordination (MC) in building MS1064 4

5 Components of IBS Scores Part 1 Structural Systems (Table 1) (50 IBS Points) Full IBS Factors : - Precast Concrete Columns, Beams & Slabs - Prefabricated Steel Structures - Timber Framed System Partial IBS Factors : - Reusable System Formworks for insitu concrete structures Nil IBS Factor : - Timber Formwork 5

6 IBS Scoring Attributes Setia Precast Sdn Bhd Components of IBS Scores Part 1 Roof (Table 1A) Full IBS Factors : - Prefab Timber Roof Truss - Prefab Metal Roof Truss Partial IBS Factors : - Precut Metal Roof Truss Nil IBS Factors : - Timber Roof Trusses 6

10 Components of IBS Scores Part 3 Other Simplified Construction Solutions (30 IBS Points) Emphasis on : - Utilisation of MS1064 Guidelines - Horizontal & Vertical Repetition - Buildability 10

11 Case Study 1 - Residential Seri Jati Apartment, Setia Alam 948 Units, 6 Blocks, 10 Storey Apartment in a single phase development 11

Landing Slabs - Precast Lift Core Walls - Precast Bathroom Slabs - Precast Air-Cond Ledges

12 Prefabricated Steel Roof Trusses Precast Walls for Roof In-Situ Typical Floor Slabs Precast Components - Precast Load Bearing Walls - Precast Non-Bearing Walls - Precast Staircases & Landing Slabs - Precast Lift Core Walls - Precast Bathroom Slabs - Precast Air-Cond Ledges Conventional Construction - Foundation - Ground Floor - Transfer Beam - RC Slab CONSTRUCTION SYSTEMS 12

IBS Score for Seri Jati Part 1 : Scoring point : Part 1 39.

13 IBS Score for Seri Jati Part 1 : Scoring point : Part / 50 Use Precast Structural Frames with in-situ concrete floor using Reusable System Formwork 13

IBS Score for Seri Jati Part 2 & 3: Part 2 18.8 / 20 Scoring point : Part 3 24.

14 IBS Score for Seri Jati Part 2 & 3: Part / 20 Scoring point : Part / /100 Use Precast Walls Follow MS1064 Vertical & Horizontal Repetition 14

IBS Score Advantages - Project has high degree of repetitions for both horizontal and vertical plain. - Architectural and Structural designs with precast intention to capitalise on precast advantages.

15 IBS Score Advantages - Project has high degree of repetitions for both horizontal and vertical plain. - Architectural and Structural designs with precast intention to capitalise on precast advantages. - High economy of scale with >900 units apartment with a single unit layout. - Construction logistic is fully considered at planning stage e.g. wall layout, work sequencing, crane s capacity and movement. 15

16 IBS Score Disadvantages - Brickwork/plastering in stand alone amenities building, box-out for M&E services/risers and kitchen/yard walls. - Non-compliance in Modular Coordination for structural elements and architectural design input. 16

17 An exciting external facade with different architecture features reduce the monotonous of the internal repetitive layout. 17

18 Steel moulds provide consistent quality in architecture features No columns and projected beams Consistent squareness Consistent quality 18

20 ACCHKL - Method to Achieve 70% IBS Score Requirement a) Columns : Sizes are too heavy for lifting if in precast components. Cast in-situ using aluminium formwork b) Beams : Precast components by Setia Precast c) Slabs : All wet areas are in-situ construction Other areas used Precast Hollow Core Slab by Eastern Pretech supported by PC Beams from Setia Precast 20

21 ACCHKL - Method to Achieve 70% IBS Score Requirement d) Walls : Structural walls used aluminium formwork & other internal and external walls Lightweight Blocks e) Staircases : Precast 21

works and fittings the smallest room with the most number of trades.

26 Further Enhancement to IBS Score System 1. Prefabrication a) Bathroom Pods/Prefabricated Pre-finished Volumetric Construction (PPVC ) - Truly industrialised system of construction, prefabrication and assembled at factory. - Eliminate on-site brickworks, plastering, tilings, waterproofing, site wirings and plumbing works and fittings the smallest room with the most number of trades. - Previous IBS Score (2005) allows a maximum of 1 point at Part 3 Prefabricated Components. - Proposed to increase IBS points at Part 2 as it comes complete with wall system and finishes. 26

and walls - To consider additional points under previous

27 Further Enhancement to IBS Score System b) Off-site prefabrication of reinforcement cage for columns, beams and walls - To consider additional points under previous IBS Score Part 3 (Other labour saving product / solution). 27

- Process is clean and systematic - Good quality finished surface - No hacking

28 2. Elimination of Labour Intensive Process a) Use of skin walls/cladding to conceal wirings and pipings, instead of traditional hacking and plastering. - Process is clean and systematic - Good quality finished surface - No hacking of RC walls and brickworks Setia Precast Sdn Bhd Further Enhancement to IBS Score System 28

equipment, scaffoldings etc. for work to be executed.

29 b) Replacement of brickwalls by using Dry Wall System (including cementitious panels and gypsum boards). - Bricklaying is a labour intensive process - Involved lot of construction logistic in moving bricks, sand, cement, water, mixing equipment, scaffoldings etc. for work to be executed. - Wet & dirty - Dry wall system is clean, fast, labour efficient and quality is easily control Where apply as a full replacement for brickwalls, should be incentively considered under previous IBS Score Part 3 (Other labour saving solution). 29

3. Revision of IBS Score 2010 a) Propose Revision to IBS Score Part 3 2010 Setia Precast Sdn Bhd - Reinstate 2005 Part 3 Item 3 (Other Prefabricated Component and

30 3. Revision of IBS Score 2010 a) Propose Revision to IBS Score Part Setia Precast Sdn Bhd - Reinstate 2005 Part 3 Item 3 (Other Prefabricated Component and Labour Saving Solution) to include more prefab structural / finished components e.g. prefab staircases, prefab bathroom unit & unitized building modules

31 Conclusion To target a higher IBS Score : 1) Design shall be modular coordinated, compliance to MS1064 (Utilisation of Standardise Components). 2) Developers & Contractors to plan for the use of IBS from the beginning including any simplified construction method. 3) Prefabrications where possible. 4) Minimise labour intensive works where possible e.g. brickwork & plastering. 5) Developers should have a preference for IBS construction so that the project sites are cleaner, less labour intensive and better quality. 6) Contractors should always be looking at more efficient construction methods. 31
