  1. Examples IBS Score Calculation

  2. Kaedah Penilaian IBS Content Scoring System (“IBS Score”) Jumlah keluasan pembinaan 1,000 m2 Keluasan penggunaan kaedah pasang siap (precast) beam/column/slab = 750m2 = 75% Keluasan penggunaan kaedah konvensional (insitu) = 250 m2 = 25% Table 1, for precast beam/column/slab, F = 1.0

  3. Kaedah Penilaian IBS Content Scoring System (“IBS Score”) Jumlah keluasan pembinaan 1,000 m2 Keluasan penggunaan kaedah pasang siap (precast) beam/column/slab = 750m2 = 75% Keluasan penggunaan kaedah konvensional (insitu) = 250 m2 = 25% Table 1, for precast beam/column/slab, F = 1.0 Table 1, for in-situ, F = 0

  4. Kaedah Penilaian IBS Content Scoring System (“IBS Score”) Jumlah keluasan pembinaan 1,000 m2 Keluasan penggunaan kaedah pasang siap (precast) beam/column/slab = 750m2 = 75% Area using in-situ = 250 m2 = 25% From Table 1, for precast beam/column/slab, F = 1.0 From Table 1, for in-situ, F = 0 Maka, bagi Part 1 (Structural System) IBS Score = ( (75% x 1.0) + (25% x 0) ) x 50% = 37.5 %

  5. Kaedah Penilaian IBS Content Scoring System (“IBS Score”) Jumlah panjang keseluruhan dinding ialah = 10,000 m run Panjang dinding panel pasangsiap (precast panel) = 7,500m = 75% Panjang dinding bata (brick) = 2,500 m = 25% Table 2, panel pasangsiap, F = 1.0 Table 2, dinding bata, F = 0

  6. Kaedah Penilaian IBS Content Scoring System (“IBS Score”) Jumlah panjang keseluruhan dinding ialah = 10,000 m run Panjang dinding panel pasangsiap (precast panel) = 7,500m = 75% Panjang dinding bata (brick) = 2,500 m = 25% Table 2, panel pasang siap, F = 1.0 Table 2, dinding bata, F = 0 Maka, jumlah score Part 2 (Wall System) = ( (75% x 1.0) + (25% x 0) ) x 20% = 15%

  7. IBS Score Calculation & EXAMPLE

  8. Example 1 2-storey Terrace House

  9. Say, from measurement taken from drawings: 1) Construction area i) Construction area ground floor = 117.0 m2 ii) Construction area 1st floor = 117.0 m2 iii) Construction roof area = 117.0 m2 Total construction area = 351.0 m2 2)Structural Systems i) Beams: Precast concrete beams ii) Columns : In-situ concrete using steel formworks iii) Floor slab: Precast half slabs floor iv) Roof truss: Prefabricated timber roof truss. 3) Wall System i) Internal wall: Precast concrete panel ii) External wall: Precast blockworks

  10. Other simplified construction solutions i) Beams: 60% complies to MS 1064 Columns: 100% complies to MS 1064 Walls and slabs: Less than 50% complies to MS 1064 Doors : 80% complies to MS 1064 Windows: 0% complies to MS 1064 ii) Horizontal repetition of structure = 100%

  11. ELEMENTS AREA (m2) or Length (m) IBS FACTOR(1) COVERAGE IBS SCORE Part 1: Structure Elements Precast beams + in-situ column with reusable formwork + precast concrete half slab floor. Ground floor area = 117.0m2 117.0m2 0.9 (117 / 351) =0.33 0.33 x 0.9 x 50 =14.9 Precast beams + in-situ column with reusable formwork (no floor) 1st floor area = 117.0m2 117.0 m2 0.6 (117 / 351) =0.33 0.33 x 0.6 x 50 =9.9 Roof truss using prefab roof truss Roof area = 117.0m2 117.0m2 1.0 (117/351) =0.33 0.33 x 1.0 x 50 =16.5 Total Part 1 351.0 m2 1.00 41.3 Part 2: Wall System External wall using precast concrete blockworks 87.8m 0.5 (87.8/167) =0.52 0.52 x 0.5 x 20 =5.2 Internal wall using precast concrete panel 79.5m 1.00 (79.5/167) =0.48 0.48 x 1.0 x 20 =9.6 14.8 Total Part 2 167.3m 1.00 Part 3: Other simplified construction solutions i) 60% beam sizes follow MS 1064 Part 10: 2001 2 60% ii) 100% of column sizing follow MS 1064 Part 10: 2001 100% 4 iii) 80% of door sizing follow MS 1064 Part 4: 2001 80% 4 iv) Horizontal repetition of structure = 100% 100% 6 Total Part 3 16 IBS CONTENTS SCORE OF PROJECT (Part 1 + Part 2 + Part 3) 72.1
