IBS SYSTEM
Industrial Building System (IBS) is a construction process or system which uses standardized building components that are mass-
produced in a controlled environment. The building components are then transported and assembled into a building structure using
appropriate machinery and equipment with minimal workers on site. Building components which are often used in the IBS projects
include panels, slabs, beams and staircase units and roof structures. There are five main types of IBS system categories that are
used in Malaysia :

The IBS systems that we applied to our building design is the precast system for the columns, beams, slabs, panel and stairs. Steel
framing is used for our roof structure and toilet pod structure, There are many advantages by using IBS system which including
reduction of site labour, minimal wastage, faster project completion and lower construction cost On top of that, this system promotes
sustainability, improves site safety, quality and productivity in the construction environment.

This IBS is made up of tunnel forms, beams and columns moulding forms, and permanent steel
formworks. This system is the least pre-fabricated among the IBS, as it normally involves site casting.
Therefore, it is subject to structural quality control, high-quality finishes and fast construction with less site
labour and material requirement.
This IBS is commonly used with precast concrete slabs, steel columns/beams and steel framing systems,
and is used extensively in the fast-track construction of skyscrapers. Apart from that, it is extensively
used for light steel trusses consisting of cost-effective profiled coldformed channels and steel portal frame
systems as alternatives to the heavier traditional hot-rolled sections.
It includes of interlocking concrete masonry units (CMU) and lightweight concrete blocks. The block
system is mainly used for non-structural wall as an alternative to conventional brick and plaster
It consists of timber building frames and timber roof trusses. Although the latter is more common, timber
building frame systems also offer interesting designs from simple dwelling units to buildings such as
chalets for resorts.
This IBS consists of precast concrete columns, beams, slabs, walls, 3D components (e.g. balconies,
staircases, toilets, lift chambers, refuse chambers), lightweight precast concrete and permanent concrete
formworks. This system produces precast concrete components by casting concrete in a reusable mold
which is then cured in a controlled environment, transported to the construction site and lifted into place .

CASTINGPROCESS
SITE CLEARING,
STRIPPING AND
LEVELLING 
The site is cleared of
rubble, and weed and also
ensured that there is no
water stagnation. 
SETTING OUT AND
EXCAVATION 
The building is set out from
the boundary line based on
guidelines from the local
authority. 
FORMWORK
The formwork for each
separate pad footing is
constructed and positioned
based on building plans in
the excavated trenches.
 
PLACEMENT OF REBAR
Reinforcement bars that
have been spaced properly
are placed into the
formwork.
 
CONCRETING 
Concrete mix is prepared
and poured into the
formwork to form the pad
footings, and then
compacted with a vibrator.
CURING
After concreting, curing is
immediately done with the
formwork locking in the
moisture and controlling the
temperature.
JOINTING TO COLUMN
The reinforced concrete pad footing
is connected to the foundation
columns by steel brackets welded to
a steel plate and secured with steel
anchor bolts.
BACKFILL AND DUMP
PROOFING
The excavated trench is then
backfilled with the excavated soil,
which is then compacted in layers
for structural integrity.

COLUMN-FOUNDATION CONNECTION
A bolted column connection is secured with anchor bolts where it can
also be used to create a column to column splice, which is impossible to do
with a socket method or with starter bars.
The column is cast into the foundation using a template as it transfer
directly tension, compression and shear forces to the reinforced concrete
base structure and is moment-resisting. Whereas the bold counterparts
known as column shoes are cast into the column at the precast
factory.
A moment-resisting connection is made quickly by lowering the column in
place and tightening the nuts to specified torque with readily available hand
tools. The installation process takes on average 20 minutes per column and
requires only a crane operator and two people on the ground. The
connection is finalized by grouting the anchor bolt recesses and joint
underneath the column with non-shrink grout.
INSTALLATION PROCESS
1. Fix the foundation anchor bolts to the PPL template.
2. Position the PPL template with anchor bolts to the foundation and cast.
3. Remove the PPL template and level the nuts.
4. Erected and lower the column.
5. Tighten the upper nuts and check the verticality.
6. Release the crane.
7. Grout the join and the column pockets.

COLUMN TO COLUMN CONNECTION
Precast concrete columns are connected together
through bolting, where the top of a lower-floor column
consists threaded bolts projecting outs, while the
bottom of an upper-floor column has a fixed base plate
containing holes to hold the bolts.
Then, the gaps are grouted afterwards with concrete
to prevent metal components from fire and corrosion.
COLUMN TO BEAM CONNECTION
The beams are set on bearing pads on the column corbels.
Next, steel angle angles are then welded to the metal plates cast
into the beams and columns and the joint will be grouted solid.

03 PRECAST REINFORCED CONCRETE BEAM
BEAM
SUITABILITY
The precast concrete beams are flexible and configuration.
They have broad capabilities to custom produce concrete
plank spans to your required specifications.
Precast concrete beams we used in our building are L and
T beams. These beams are designed according to the
shape of column. It conforms the column as a slotting
method.

JOINT DETAIL
BEAM TO BEAM CONNECTION
The secondary structure (beam)
sits on the primary beam. It is
connected by the slotting method
with the help of neoprene, steel
plates, anchor rods, tubes and
sockets.
SLAB TO BEAM CONNECTION
Hollow core slabs are set on bearing pads on the precast beams. Then, steel
reinforcing bars are inserted into the slab keyways to span the joint and increase
tensile strength. These reinforced precast concrete beams for composite slabs
are completed with a concrete topping slab and concrete infill at beam ends and
column caps.
1. The hollow core slab is set on the precast beam.
2. Steel reinforced bars are inserted into the slab keyways to span the joint.
3. The join is grouted solid.
4. The slab may remain bare or topped with few inches of cast in place concrete.

04 PRECAST HOLLOW CORE CONCRETE SLAB
SLAB
SUITABILITY
The precast concrete hollow core slab is suitable for our
building as the tubular voids significantly reduces the weight
of the slabs while maintaining the strength as compared to a
solid concrete floor slab of the same size. This results in an
efficient lightweight unit that is suitable for resisting the
bending moment from loads in a multi-storey building. The
long-span capability is ideal for multistory buildings.
The slab we use for our building is the precast hollow core
concrete slab, which is a precast prestressed concrete
element with tubular voids extending the full length of the
slab. It consist of prestressing tendons within the elements
to provide a predetermined force needed to resist external
loadings and cracks. There is freedom in length of units,
and splays and notches can readily be accommodated.

FABRICATION PROCESS
The dry casting process which is mainly used for hollow core wall panels and slabs is
used for fabricating our precast hollow core slab.
PREPARATION OF BASE
MOULD
This process is to ensure that
the base mould is free from
debris and old mortar and
ready for the new mortar.
APPLICATION OF FORM
RELEASE AGENT
And anti-rust form release
agent is applied over the
strands and mould to ease
removal of the dried mortar.
PRESTRESSING STRAND
HAULING AND TENSIONING
The strand spacing and
pattern is manually regulated
to ensure evenness.
CONCRETING
Mortar that has been concrete
grade approved is poured into
the mould and compacted with
a clamp on vibrator.
CURING
Curing begins immediately
after concreting by protecting
the panels with tarpaulin to
maintain the moisture and
temperature.
DETENSIONING OF
STRANDS
The strands are detensioned
to release the dried concrete
panels from the mortar using
the hydraulic jacking method.
FINAL INSPECTION AND
TRANSFER
Inspections are done to check if
there are any major defects on the
concrete slabs and to ensure the
evenness of the tubular voids.

Thefloorslabsundergoaspecificsetofprocessesduringinstallationtoensurethat
theslabsareproperlyplacedandbonded.
INSTALLATIONPROCESS
ON SITE INSPECTION
The quality of all transported slabs
are verified prior to unloading it.
This is to make sure that the slabs
do not have damage that may be
caused by loading or transportation
events.
UNLOADING AND HOISTING
Unloading and hoisting of the slabs
are done with a hoisting traverse,
which consists of a lifting beam with
two hoisting grippers. The position
of hoisting grippers on lifting beam
is adapted to length of slab.
INSTALLATION
The hoisted slab is directed into
proper position directly above the
bearing surface, and the safety
chains are unhooked. The slab is
then lowered into planned position,
and unhooked from the crane.
ADJUSTMENT AND CURVATURE
EQUALIZATION
When mismatches in slab curvature
on the lower side of the floor exceed
the allowable size, the curvature will
equalized via help of adjustable
struts lifting the lowest slab.
POSITIONING AND
INSTALLATION OF TIES
Since the floor of our building
functions as a diaphragm, the ties
are installed with the longitudinal
walls.
GROUTING
The installation joints that are
between the slabs and also the ends
of slabs are filled with fine aggregate
concrete, then compacted using an
internal vibrator to strengthen the
bond between the slabs.

05 PREFABRICATED STEEL TOILET POD
TOILET POD
SUITABILITY
Prefabricated Toilet Pods are suitable for our building as they
can be easily duplicated in production for multi storey units
that require repetition of modular components.
Prefabricated Toilet Pods are prefabricated modular
building components that include the interior finishes and
system components of a bathroom. Everything is
fabricated off site and it is ready to use once installed on
site along with the piping systems. The bathroom in pod is
framed with hollow core steel bars which are welded
together.

06 PRECAST R.C. STAIRS
STAIRCASE
SUITABILITY
The precast single unit concrete stair is suitable for our
building as unlike solid concrete steps, they are hollow,
lighter and less prone to settle over time. Even if settling
occurs, the remediation is an easy one as the lightness of the
stair unit allows them to be conveniently replaced. This makes
the stairs safe and suitable for multi storey buildings in the
long run.
The stair system we use for our building is the precast
single unit concrete stairs where every element of the
stair is prefabricated into a single unit. The flights are
extended to include the landings, which will only then be
jointed to the floor slabs.

FABRICATION PROCESS
The normal casting process used for precast reinforced concrete components are
used for our precast RC concrete stairs..
ASSEMBLY OF MOULD  
The mould is assembled
accurate to the dimensions of the
stairs within the specified
tolerances.
FIXING OF REBAR  
Rebars are correctly positioned
and spaced using a fabrication
rig, and then properly secured to
the mould.
CURING  
The concrete is cured to prevent
it from losing moisture too rapidly
and losing its strength. This is
done by leaving the formwork in
place to lock in moisture.
CONCRETING 
Concrete mix is added to the
mould and compacted using the
vibrator.
DEMOULDING

PRECAST CONCRETE SANDWICH PANEL
WALL
SUITABILITY
The precast concrete sandwich wall panel is suitable as the
insulated void significantly reduces the weight of the panels
while maintaining the strength as compared to a solid
concrete wall panel. This results in an efficient lightweight unit
that is suitable for resisting the bending moment from loads in
a multi-storey building. The panels can be produced with
almost any surface finish on both sides, the interior and
exterior. This eliminates the need for cladding.
The wall we use for our building is the precast concrete
sandwich wall panel, which comprises of two wythes of
precast reinforced concrete panels separated by a layer of
expanded polystyrene foam (EPS} as rigid insulation.

ROOF
SUITABILITY
Steel portal frame and roof trusses are suitable for our
building as they are insusceptible to shrinkage, termite
infestations, rotting and warping. Steel roofs can also be
installed in poor weather, eliminating expensive downtime.
Prefabricated metal roof structure also reduce costs and
labor time, as workers only take care of assembly.
The roof structure we used for our building are steel frame
and steel roof trusses. The components are prefabricated
and assembled in a factory and then installed on site.

The hoisted roof structure is directed into
proper position directly above the footing, then
lowered and bolted to the footing before being
unhooked from the crane.

GUSSET PLATE
Truss members are connected
by using gusset plate where
members of two different
angles are bolted as one
centre node. Bolting is one of
the preferred method of
connecting members on the site.
Staggered bolt layout allows
easier access for tightening with
a pneumatic wrench when a
connection is all bolted.
WELDING
Welding takes part as fabrication process which joins the
metals by causing act of fusion, which is distinct from lower
temperature metal-joining techniques such as brazing and
soldering. This process do not melt the base metal whereas it
joins the roof truss members at parts which readily available
connectors couldn’t be used.
Metal plate footings are bolted
onto the beams, then truss
members are attached onto
the metal plate footing using L
brackets

CONCLUSION
Industrial Building System (IBS) is gaining traction in Malaysia as more parties begin utilizing it. Because components are custom
built to exact requirements in a controlled, factory environment, quality can be closely monitored and standardised, reducing defects.
In projects with a high degree of repeatability, cost benefits appear as high-quality components can be replicated numerous times,
reducing the price per unit.
As for our proposed design, the IBS score is calculated as an overall assessment to the system applied for our proposed design in
each component. We had gained over 89.2%, which contributes to a good final outcome. In other words, we have managed to apply
IBS effectively in our construction process. Apart from that, we were able to demonstrate a comprehensive understanding of IBS
construction process through model making apart from just understanding them through theories.
