1.0 INTRODUCTION
1.1 AIM AND OBJECTIVE
This project which is related to the topic of Industrialised Building System (IBS), is carried out in a group of 5-6 members, each group are required to:
1. Design a 3-storey apartment block using mainly IBS components.
2. Construct a physical model of the apartment block to show the IBS components in detail.
This project is carried out in order to:
1. Develop our understanding in different types of IBS construction method.
2. Build up our capability in applying appropriate IBS construction method in the production of a model for an apartment building.
1.2 HISTORICAL BACKGROUND OF INDUSTRIAL BUILDING SYSTEM (IBS)
The concept of IBS where blocks are divided into a manageable sizes for easier and faster transportation was first introduced by UK in early 1600s. In that period, wood panel transportation was happening from England to North America. One of
the well-known project that used IBS system was the Crystal Palace. It tooks only four months to complete using light structure etc : Glass, wood and steels.
In 1963, Malaysian architects from the Public Works Department(PWD) discovered IBS system in Europe when the Ministry of Housing and Local Government in Europe were focusing on improving house development quality. In that period,
Public Works Department(PWD) sent severals Architects to Germany, Denmark and France for exploring new construction techniques in different countries.
After the successful discover on IBS system, government in Malaysia adopted the concept and apply it into several major projects, but all of the projects shares the same objective which IBS can totally provide, time-saving, affordable and can be
build in substantial quality. There are few well-known structural that makes Malaysia iconic such as the Petronas Twin Tower., which only use 6 years to build up to 88 storeys.
However, IBS system can be apply only on simple designs in the early discoversation on this construction technique,to overcome the issues caused by IBS technology, there a different authorities who’s responsible for implementing strategies and
introducing breakthroughs to improve the performance and quality. In the same time, to reduce uses of foreign labour to avoid overwhelming workforce that take over local industry.

1.0 INTRODUCTION
1.3 TYPES OF INDUSTRIALISED BUILDING SYSTEM (IBS)
There are generally six main types used in Malaysia to make an employing conventional technology transform to the IBS which is more systematic and mechanized.
1. Precast Concrete Framing
It includes precast concrete walls, slabs, columns, beams, 3D Components such as balconies, staircase, toilets, lift chambers, refuse chamber, lightweight precast concrete, and permanent concrete formworks.
2. Steel Formwork System
The least prefabricated among the IBS. It is made up of tunnel forms, beams and columns moulding forms, and permanent steel formwork. It involves site casting. These products provide a high quality finishes,high quality control and fast
construction with less site labour and demand for materials.
3. Steel Framing System
This system frequently used with precast concrete slabs, steel columns and beams and steel framing systems. Besides, it is popularly used for light steel trusses formed channels and steel portal frame systems as alternatives to the heavier
traditional hot-rolled sections. This system is widely used in fast-track construction of skyscrapers, large factories or exhibition hall that need wide areas.
4. Timber Framing System
It involves prefabricated timber truss, beams, and columns. It is widely used in chalets for resorts based on its high aesthetic values and attractive designs.
5. Blockwork System
This system includes of interlocking of masonry units (CMU) and lightweight concrete blocks. It is mainly used for non-structural walls as an alternative to conventional brick and plaster.
6. Innovative System
This is the latest IBS type which incorporates various “green” elements. Therefore, new materials are being introduced at the fabrication stage such as gypsum, wood wool, polymer, fiberglass and aluminum-based IBS components. For
example, it mixes polystyrene and concrete to produce IBS components of a wall which has better heat insulation properties.

1.0 INTRODUCTION
1.4 ADVANTAGES OF INDUSTRIALISED BUILDING SYSTEM (IBS)
According to CIDB (2003), the IBS has more advantages compared to conventional construction method:
1. Less construction time.
IBS requires less construction time because casting of precast element at factory and foundation work at site can occur simultaneously and the work at site is only the erection of IBS components.
2. Considerable cost savings.
The formwork of IBS components are made of materials that allows for repetitive use.
3. Saving in labour.
When the IBS components are produced in factory, higher degree of utilisation of machine is permitted and the use of labour will be reduced.
4. Less labour at site.
The use of IBS will reduce the construction process at site and consequently reduce the number of labour required at site.
5. Reduce material wastage.
The utilisation of machine during the production of IBS components lead to higher degree of precision and accuracy in the production.
6. Higher quality and better finishes due to careful selection of materials, use of advanced technology.
Production in factory is under sheltered environment produced better and strict quality assurance control.
7. Faster project completion due to rapid all weather construction.
The effects of weather on construction operation are less due to the fabrication of IBS components is done in factory while at site is only erection of the components.
8. Flexibility.
IBS provides flexibility in the design of precast element so that different systems may produce their own unique prefabrication construction methods.
9. Increase site safety.
Utilisation of IBS components leads to less construction process especially wet work at site. This will lead to the neater site condition and increase safety.
10. Environmental friendly.
The use of IBS will decrease the using of timber formwork on construction projects.

1.5 DISADVANTAGES OF INDUSTRIALISED BUILDING SYSTEM (IBS)
1. High initial capital costs
At the initial stage, it involves all costs from the construction of factories, the casting of beds and the acquisition of support machinery.
2. Jointing problems between components
Malaysia is a country with an equatorial climate, often experience heavy rainfall and this may leads the leakage problems. When a leakage manifests, it may other problems such as dampness and corrosion.
3. Site Accessibility
Site facility and accessibility is one of the most important factors in the implementation of the IBS. IBS requires enough access to transport all the components from the factory to the construction sites. If delay due to transportation
process, the installation of the components also will be affected and this result in a delay in the overall construction.
4. Large Working Area
Construction projects involve IBS require large work areas for the plants, trailers, tower cranes and storage for the IBS components. However, most construction sites especially those in cities are often crowded and cannot provide the
required area.

3.2.3 BEAM TO COLUMN CONNECTION
The I beams are made of high-performance concrete pre-cast into multi-section metal formworks, vibrated at high frequency and quickly cured by an appropriate thermal cycle. Concerning pre-stressed beams, the prestressing process is
performed by stretching each single-strand and then anchoring the latter on the stretching heads. When the necessary concrete resistance is achieved, strands are released and then cut. The whole production cycle is complete within one
day. Post-stressed beams or sliding-cables beams, before casting concrete into the formworks, standard reinforcement and sheaths is arrange.
These latter serve as accommodation for pre-stressing cables which carry special anchorages at their edges. The concrete is compacted by high frequency vibration. Once also the curing process is complete, the cables are inserted into
the sheaths and the stressing is performed by specific stressing machinery.
Precast I beams have length of 500mm, height from 610mm, casting thickness from 170 mm; prestressing up to 1.800 ton. The beams when assembled can be positioned side by side or spaced. They are joined together by an on-site
additional casting forming a slab to better distributes loads crosswise. The beams are set on bearing pads on column corbels. Steel angles are welded to metal plate cast into the beam and columns and the joint is grouted solid

3.2.4 COLUMN TO COLUMN CONNECTION
Precast concrete columns are connected together through bolting, the top of a
lower-floor column contains threaded bolts projecting out, while the bottom of an
upper-floor column has an embedded base plate containing holes to engage the
bolts. The block-outs in the column above the holes are grouted after the
connection has been made to protect it from corrosion.

Ties between slab
Connections between hollow-core slabs and supporting members are made using
site-cast concrete fill and reinforcing steel. In addition to the concrete fill used for
connections, a site-cast concrete topping is used over the slabs.
The hollow core keyways can be
grouted at the same time as the
columns and beams when using
a grouting bucket.
This method can also avoid
the use of a concrete pump
truck.
The grout will only go inside the
hollow core slabs a few centimeters.
The hollow core slabs are provided
with plugs at the end of the cores to
prevent grout from flowing inside.
Hollow core slabs are set on bearing pads on
precast I beam. Steel reinforcing bars are inserted
into slab keyways to span the joint then grouted
solid. Precast hollow core slabs connected at their
ends to a “I” precast beam by steel ties.
Grouting
The topping provides structural integration of slab units and increases the floor’s
fire resistance and sound insulation. It also functions as a leveling bed, particularly
with units with uneven camber. Topping, used is about 2 inches thick and
reinforced with welded wire reinforcement

3.2.5 WALL TO SLAB CONNECTION
Bolted Connections
Bolted connections simplify and speed-up the erection operation, because the connection is positive immediately. Final alignment and adjustment can be made
later without tying up crane time. Bolting is in accordance with the erection drawings.
Welded Connections
Welded connections is used in the erection of precast concrete. These connections are structurally efficient and adjust easily to varying field conditions. The
connections are made by placing a loose plate between two structural steel plates that are embedded both in the cast-in-place or the precast concrete panel
and welded together. Welded connections is installed exactly as shown on the erection drawings and details.
Precast panels are connected to each others or to floor and roof elements by using metal plates and angels, they are fastened by welding or bolting. Connections may be projected or recessed to provide flush finishing
surface.
Temporary bracing for tilt-up panels
For the bracing and quick, secure adjustment of precast concrete elements and wall and column formwork. Each element must be supported by at least two push-pull props.

3.3 IBS CONSTRUCTION ADVANTAGES AND DISADVANTAGES
3.3.1.1 ADVANTAGES:
1. Precasting is great for producing large numbers of identical components.
2. The construction is done on the ground rather than at a height.
3. It can be done inside a climate-controlled structure, eliminating problems of rain, dust, cold, or heat.
4. Specialised formwork (moulds) can be built for doing many repetitions of the same component. Specialised equipment can be used to make, move, and pour the liquid concrete.
5. Curing of the concrete can be done in a controlled environment.
6. The quality of precast components can be very high.
7. Construction can be very quick since the components can be made beforehand.
3.3.1.2 DISADVANTAGES:
1. Since each piece is made separately, the structural frame or system is not monolithic or continuous like regular concrete construction. The joints between pieces create structural discontinuity. The forces of the building
will pass through these joints, so they have to be designed to transfer these forces safely and properly. Note that precast concrete can be used for non-structural members too.
2. As the building is made of discrete components, the joints between adjacent members have to be sealed with special sealants to make them waterproof.
3. Each precast component is usually large and heavy. This means that cranes are required to lift them in position; these cranes are required to operate over the entire building volume. Since there will only be a few cranes at
site, the time taken by the cranes to pick up a piece and shift it to its final position becomes critical in determining the building schedule.
3.3.2.1 ADVANTAGES:
1. It is light, and allows quick construction with no heavy tools or equipment. Every component can easily be carried by hand - a house essentially becomes a large carpentry job. The main tool is a handheld nail gun.
2. It is able to adapt itself to any geometric shape, and can be clad with a variety of materials.
3. There are a huge variety of products and systems tailored to this type of construction.
4. Timber framed construction allows for the use of semi skilled labour for the manufacture in factory controlled conditions.
5. Rapid completion on site is easily achieved with less wet trades involved.
6. The occupier of a timber framed dwelling benefits from the higher insulation which can easily be achieved. The use of low thermal capacity linings absorbs less heat than masonry walls making it is easier to reach the
required comfort temperature more quickly.
3.3.2.2 DISADVANTAGES:
1. It is not highly fireproof, as it is made of wood.
2. It is not strong enough to resist major wind events such as tornadoes and hurricanes.

5.0 CONCLUSION
In this project, we were able to identify and collected relevant research data relating to Industrialised building system (IBS) construction. For project 1, we were required to do a thorough report on the construction process using IBS
and develops our knowledge in the different varieties of IBS available in the current market. A set of architectural and documentation of an apartment is clearly explained in the report where IBS is used. By constructing an
apartment, with most of its materials prefabricated, we demonstrated our comprehensive understanding on IBS through model making that includes the related basic structural elements and structural documentation. It also enable
us to access and understand the method of calculating IBS score.
Through this module, we have understand and incorporate Industrialized building systems in our building where we learn that IBS requires less construction time because casting of precast element at factory and foundation work at
site can occur simultaneously and the work at site is only the erection of IBS components. This leads to earlier completion of the building. Less labour on site due to precast component done off site will reduce the construction
process on site and consequently reduce the number of labour required at site dramatically. We were able to fully optimised the use of material due to the utilisation of machine during the production of IBS components and
ultimately lead to a higher degree of precision and accuracy in the production and consequently reduce material wastage thus offer a much higher quality and better finishes. Other than that, the formwork of IBS components are
made of steel, aluminium or other materials that allows for repetitive use and this leads to considerable cost savings.
In conclusion, IBS construction is an efficient and cost effective construction system.
