Dari Meja Pengarang
IBS Digest kali ini memberi sedikit fokus
terhadap penggunaan aplikasi IT di dalam
industri pembinaan. Wujud dan jayanya
sesuatu projek IBS adalah bermula dari
peringkat awal iaitu peringkat reka bentuk.
Inovasi ini akan dapat meningkatkan kualiti dan produktiviti, keberkesanan dari segi
kos, tempoh penyiapan projek lebih cepat
di samping keberkesanannya terhadap
pengurusan projek yang lebih efisien.
Pihak pengarang cuba memperkenalkan satu kolum baru khas berkaitan Kordinasi Modular (Modular Coordination–MC).
MC bukanlah satu sistem pembinaan tetapi
ianya adalah satu konsep dimensi komponen dan ruang yang berasaskan kepada
Piawaian Malaysia MS 1064. Sememang sejak tahun 1998 lagi pihak CIDB mengambil
inisiatif mempromosikan MC seiring dengan IBS. Salah satu jentera penggerak MC
adalah Jawatankuasa Pakar MC yang terdiri
daripada arkitek dan jurutera serta para
akademik dari universiti.
Di dalam Ucapan Bajet 2006 juga Perdana Menteri ada menegaskan bahawa
kerajaan akan memastikan komponen IBS
yang digunakan mematuhi Piawaian Malaysia MS 1064. Piawaian ini akan memastikan kualiti dan mengawal kos pembinaan.
Konsep Just-In- Time (JIT) di dalam
pengurusan pembinaan memberi kesan
yang besar terhadap pengurusan logistik
di tapak pembinaan. Walaupun konsep JIT
lebih berjaya di sektor pembuatan, kini sektor pembinaan telah mula memberi perhatian terhadap konsep ini melalui IBS.
Di sepanjang tahun 2005, banyak program telah di anjurkan oleh pihak CIDB
dalam mempromosikan IBS. Selain itu CIDB
juga mengadakan program usahasama
ataupun berceramah secara jemputan oleh
pelbagai agensi kerajaan dan juga institusi
Pihak Kumpulan Pengarang amat mengalu-alukan sebarang komen dan juga
sumbangan artikel agar ilmu yang disebarkan melalui IBS Digest ini dapat dicernakan
bersama pembaca-pembaca majalah ini.

IBS: For technology
to integrate the
The industrialisation of construction changes how the
industry will look and work. It is nothing less than a
paradigm shift. And it is one that will add to the portfolio of
builders the roles manufacturers and logistics managers.
Industrialisation of construction has the
distinctive feature of moving expensive
activities from site to the workshop environment. In a factory, there are greater opportunities for control over quality as compared with the construction site.
Subsequently, the quality of the building project will be improved, costs will be
reduced and time to completion will be
shortened. In addition, modular construction and site logistics are also expected to
be more efficient.
However, to achieve these benefits,
builders have to learn new roles i.e., integrating the manufacturing and assembly
process with traditional site construction.
New processes introduced by IBS also impose changes on how site logistics and
construction will work.
Software makers like Autodesk came up
with solutions that could make these roles
more easily assumed, to reduce wastage
in time and resources, as well as improve
productivity. The Building information
modelling (BIM) approach that Autodesk
has been advocating allows this during the
design phase. Designers can build, analyze
and plan the building project on the computer. Thus allows further effectiveness in
reducing unnecessary on site rectification.
Design and data creation take
on added importance
Using offsite factory based production
means that new methods in planning for
construction is needed. In addition there
is need to take into consideration the control over the production as well as on-site
assembly processes. Builders now come
face-to-face with new supply chain relationships.
Design is made more prominent in the
process because it matters for safe construction and for the reduction in mistakes in the
manufacturing of components. Design is
the first and arguable the most important
step in creating data that is shared during
the entire building life cycle management
(from design, manufacturing, assembly and
construction, and property management).
Information captured in design phase
provides details of types of components
needed, material for that component, the
amount of that component, and subsequently the cost. The availability of details
like these in a uniform format for multi-party users makes supply chain management
more effective, thereby reducing wastage
in time and resources.
Central to this is the concept of building information modelling (BIM).
What is BIM?
Building information modeling is an approach to building design, construction,
and management. It supports the continuous and immediate availability of project
design scope, schedule, and cost information that is high quality, reliable, integrated,
and fully coordinated. Though it is not itself
a technology, it is supported to varying degrees by different technologies.
Building information modeling is, essentially, the intersection of two critical ideas:
• Keeping critical design information in
digital form makes it easier to update
and share and more valuable to the
firms creating and using it.
• Creating real-time, consistent
relationships between digital design
data—with innovative parametric
building modeling technology—can
save significant amounts of time and
money and increase project productivity
Technologies for building
Although building information modeling is
an approach and not a technology, it does
require suitable technology to be implemented effectively. Examples of some of
these technologies, in increasing order of
• Object CAD
• Parametric building modeling
Figure 1. Technologies for BIM
Parametric Building Modeling
The orange line on the chart represents
parametric building modeling technology.
Parametric building modeling is analogous
to the decision support systems used in
the financial community. These systems
combine a data model (geometry and
data) with a behavioral model (change
management) that gives meaning to the
data through relationships. This provides
an integrated system that can be used to
simulate the behavior of a real-world system—in this case, a building. Examples of
the most advanced features of this kind of
system are real-time self-coordination of
the information in every view, and the assurance of the quality of the information
coming from the system.
Some other important characteristics
of software based on parametric building
modeling technology include:
OKTOBER – DISEMBER 2005
• Information about the entire building
and a complete set of design documents
are stored in an integrated database.
All of the information is parametric and
therefore completely interconnected.
• Any change to the relationships among
objects is always instantly reflected
throughout the rest of the project—in
all representations of the project.
• All relationships within the model
are available for user definition—not
just relationships (such as a window
hosted by a wall) that have been
preprogrammed by the developers.
This includes graphical definition by the
end user of parametric objects.
Just as a spreadsheet is a tool for thinking
about numbers, software built on parametric building modeling technology is a tool
for thinking about buildings. And just as a
change made anywhere in a spreadsheet
is expected to update everywhere with
no further intervention from the user, so
a change made anywhere in a parametric
building modeler is immediately reflected
Current file-based CAD and object CAD
tools may be used to some degree to support building information modeling, but
require myriad supporting technologies
and the aggregation of information across
diverse, independent applications. Only a
purpose-built integrated data architecture
built around a parametric building model
can provide the immediate and fully coordinated representation of a project across
all views, drawing sheets and schedules
that is necessary to eliminate errors and
provide clarity and confidence in decision
Autodesk offers products based on
all three building design and documentation technologies, and fully understands
the pros and cons of each. As shown on
the chart, parametric building modeling
technology is uniquely suited to supporting the highest level of building information modeling effectiveness at the lowest
level of effort. Parametric building modeling uniquely offers the concurrent and immediate availability of all of the important
information about the building that results
in higher quality work, greater speed and
productivity, and decreased costs.
However, as also shown on the chart,
this technology requires the wholesale
adoption of building information modeling
to put it to use. There is no way to use this
technology in a traditional, non-building
information modeling environment. Using
this technology can deliver tremendous
business benefits, but doing so requires a
departure from traditional ways of working.
Moving from CAD-based technology to object CAD technology can be an incremental or evolutionary change, but moving to
parametric building modeling technology
for building information modeling requires
a new way of working.
Autodesk® Revit® software is an example of parametric building technology. It is
purposebuilt for building industry professionals ready for a new way of working and
the correspondingly high level of building
information modeling benefits that go with
it. Unlike the evolutionary path of Autodesk
Architectural Desktop, Revit is inherently a
building information modeler, and there is
no effective way to use Revit in any other
way. It delivers only a fully integrated, selfcoordinating building information model.
Autodesk® Revit® worksharing
for multi-user collaboration
facilitates IBS communication.
The construction industry has borne no
light criticism for its inertia in adopting IT
to boost productivity. Wastages happen
as change in data are not communicated
clearly and promptly before building mistakes commence. In industrialised building
systems, the layers of communication are
expanded. There is now need for the feeding of design information to the factory,
which will communicate upstream about
volume, type and cost of raw materials.
Add to that feedback from factory to the
drawing board and the outcome of that
communication to parties responsible for
other parts of the building life cycle- logistics between factory and construction site,
construction site logistics and the actual
Autodesk Revit Worksharing distributes the power of the Revit parametric
building modeling environment across the
project team. Worksharing provides a complete range of collaboration modes from
entirely on-the-fly, simultaneous access
to the shared model, through the formal
division of the project into discrete shared
units, to complete separation of project
elements or systems into individually managed linked models. Worksharing allows
the team to choose the best way to collaborate and interact based on their workflow
and the project requirements.
Starting your first multi-user
On many building projects, designers work
in teams with each assigned a specific func-
tional task. This involves simultaneously
working on and saving different portions
of the project. This document will give you
important information to ensure your success on large ®industry
specific projects on
the Autodesk Revit platform for building
information modeling system with many
Autodesk® Revit® Worksets
Autodesk Revit projects can be subdivided
into Worksets. A Workset is a collection of
building elements (such as walls, doors,
floors, stairs, etc.) in the building. In the
Autodesk Revit project, users have the
option of checking out entire Worksets or
individual elements in a Workset. All other
team member may view these elements or
Worksets, but are unable to change them,
preventing possible conflicts in the project.
In this manner, Worksets function similarly®
to External References (xrefs) in AutoCAD
software, but with the additional ability
to propagate and coordinate changes between users.
Team members adding and changing
elements in Worksets can save their work
to a local file on the network or their own
hard drive, and publish work to a central
file whenever they choose. They can update their local files at any time with the
latest changes other team members have
published. This ability to ‘reload,’ to see
changes, is similar to the xref workflow.
Things to Think About When
Creating New Worksets
As a project evolves, it may be necessary
to add worksets in order to provide the
maximum flexibility in usage and minimize
interference between members of the project team. Worksets can be created at any
time using the New option of the Worksets
dialog. They will become available to the
project team as soon as the user who created them makes a Save to Central. In the
Autodesk Revit project, with the ability to
make elements editable, it may seem unnecessary to make more than one workset
at all, but there are still several compelling
reasons listed below.
Decisions made when sharing a project and
setting up its Worksets can have long-lasting effects on the project team. AutoCAD
users will recognize some of these implications from setting up xref structures for
projects. In general, when setting up Work-
