INTRODUCTION 1.1 Background Industrialized Building System (IBS) is identified by the built and environment industry and government in Malaysia to represent the development of construction industrialisation and the use of pre-fabrication of components in building construction. IBS is a construction method in which components are manufactured in a controlled environment (on or off site), transported, placed and combined into a structure with minimal additional site work.
There are five components in IBS system mainly popular apply in building construction, which are column, beam, slab, wall and roof truss. In Malaysia, market of IBS manufacturers are growing due to the government requirement of 70% of IBS components must be used in government projects which cost more than RM 10 million. It is to achieve the effectiveness in building industry sector.
1.2 Type of IBS system in Malaysia − Precast concrete system − Timber framing system − Innovative system − Blockwork system − Steel framing system − Reusable formwork system 1.3
Advantages and disadvantages of IBS System Advantages of using IBS system: − Controlled quality − Higher productivity − Cost saving − Reduced maintenance requirements − Time consuming less than traditional construction − Reduction of unskilled worker − Safer working environment − Reduce wastage − Less relying on foreign human resource Disadvantages of IBS system: − Improper planning within corporations will lead to failure − Inflexibility to renovate after building completion − Limited skilled worker − Transportation fee is higher

APPLICATION OF IBS SYSTEM For this assignment, we were required to design an 100m2 apartment which applying IBS system to construct. Our group chose to use the following systems to achieve our IBS scoring: 1. Precast Concrete Column & Beam System 2. Blockwork For External Walls 3. Precast Concrete panel for internal walls 4. Precast Concrete Slab System - Hollow Core Slab 5. Precast staircase 6. Steel truss system
The aims of using IBS system as above are to construct an effective and low budget apartment. The advantages of having these systems improve the flexibility on space and facade design.
2.1
Precast Concrete Beams & Columns
Precast concrete beams are made in several standard shapes. The projecting ledgers on the L-Shaped beams and inverted tee provides direct support for precast slab elements. They conserve headroom in the building by supporting slabs near the bottom of the beams, compared to rectangular beams without ledgers, where slab elements must rest on. Precast concrete columns are usually square or rectangular in section and may be prestressed or simply reinforced.
2.2
Wall System 2.2.1 External wall - Concrete Block Work Bricks and blocks are components of durable masonry construction in which uniformly shaped individual units are laid in courses with mortar as the bed and binding material. They consist of high mass materials with good compressive strength formed into units that can be lifted and handled by a single worker. Solid brick or blockwork walls deliver good load bearing capacity along with substantial thermal mass to provide a unique combination of structural, thermal and aesthetic benefits.
2.2.2
Internal wall - Precast Concrete Wall Panel
The precast concrete units provide an easy & cost effective alternative to a shuttered or block wall reducing the predictability of time on site. The controlled factory environment ensures accurate dimension with quality appearance. Cast in sockets can be provided at the ends of the units in situations where panels are being clipped to the supporting steelwork. An interlocking tongue and groove helps distribute the load across a number of panels.
2.3
Precast Concrete Slab System - Hollow Core Slab
The most fully standardized precast concrete elements are those used for making floor and roof slabs. These may be supported by bearing walls, masonry, frames of steel, sitecast concrete or precast concrete. Four kinds of precast concrete slab elements are produced. For short spans and minimum depth, solid slabs are appropriate. For longer spans, deeper elements must be used, and precast solid slabs, like their sitecast counterparts become inefficient because they contain too much dead weight of non-working concrete. The hollow-core precast concrete slabs were chosen to be used in our project for its ability to run mechanical and electrical appliances through the cores (voids) while eliminating ductwork in which would save cost and time. The basic fundamentals of a hollow-core precast concrete slab is its characteristics of combining the compressive strength of concrete with the high tensile strength of steel strand.
2.4
Precast Staircase
Precast concrete staircase is ideal solution for similar and repetition concrete staircase construction in high-rise building. It forms well as suspended concrete floor systems with either beam and block or precast concrete floors . Precast staircase is a dry construction manufactured in factory then transport to site. Having precast concrete as part of building has follow advantages: High quality finish gives a longer life span, less maintenance Excellent acoustic characteristic addressing sound transfer comparing to steel and timber staircases Best choice as fire escape staircase During the construction phases, it as safe access to subsequent floors Easy to be installed and less messy framing.
Besides, there are two way to install precast concrete staircase, which are dry joint and wet joint.
2.5
Steel Roof Truss System
A standard truss is a series of triangles - a stable geometric shape that is difficult to distort under load. Regardless of its overall size and shape, all the chords and webs of a truss form triangles. These triangles combine to distribute the load across each of the other members, resulting in a light structure that is stronger than the sum of the strength of its individual components. Most roof trusses have webs that run at an angle between top and bottom chords. The gable-end truss must be supported along the entire length, and stabilized at the truss/wall intersection. There are a number of truss types that leave space for attic storage or living area. In any roof truss, however, attic or living space comes at a price. The bottom chord of the attac truss also acts as a floor joist and must be sized to accommodate a live load.

CONCLUSION
On a final note, we understand the importance of learning and being aware that the IBS systems are very profitable especially in the case where the project involves rapid construction and limited construction period. In lieu to that, based on the calculations of the IBS Score , in order to get a high IBS Score, a couple of things are to be taken into consideration; 1. Design shall be modular coordinated, compliant to MS1064 (Utilisation of Standardized Components) 2. Developers & Contractors are to plan for the use of IBS from the beginning including any simplified construction method. 3. Prefabrications where possible 4. Minimize labour intensive works where possible; Eg; 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.
