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​ ​100m​2​​ ​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.

IBS​ ​SCORE​ ​CALCULATION


5.0

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.
