Changes that BIM - Building Information Modeling, has brought in construction industry are much
bigger as compared to the transformation that CAD brought about in traditional
drawing practices. While CAD got introduced as a tool for producing engineering
drawings, BIM has been putting information at the heart of construction
projects, empowering every stakeholder who utilizes that information, transform
the project environment at large.
CAD
to BIM transformation
CAD – Computer Aided
design process had unpredictable ways and means of coordinating data across the
construction projects. To eliminate the hassles and leverage BIM benefits to
its fullest, CAD clubbed with Autodesk Revit and VectorWorks, were introduced;
and became favorite of tens of hundreds in no time. This new avatar of CAD
facilitates more prominent data management in throughout the construction
project environment.
BIM the new way of
processing and collaborating information with data weaved in the 3D model;
enables the merging of specific models created by various disciplines to offer
a complete overview of the project. Information is added straight to the model clubbed
with materials, size, functions, time and other related data. Earlier, the design
process in the construction industry highly depended on the efficiency of
drawings and particulars to temporary workers, from concept design to final
construction and beyond. However with BIM, it is all about
bringing the information and various elements together, so as to frame a
logical arrangement of data.
For a few years, each
foundation had its own meaning of BIM; i.e., the UK BIM Task Group characterized BIM as “value-creating
collaboration through the entire life-cycle of an asset, underpinned by the
creation, collation and exchange of shared 3D models and intelligent,
structured data attached to them”. So if put simply, BIM places data
administration and information trade at the heart of the design procedure.
With the increase in the
site or the building, the amount of information also increased alike, leading
the engineers and contractors to handover information overload to clients, this
was no good. Ideally the client is supposed to receive the right amount of
information with right data. Addressing this challenge by introducing two new
roles with newer project management responsibilities was not a big task for
those working on BIM modeling.

walking in, integrating BIM across the project lifecycle and ensuring everyone
involved in the project are following the protocols, was implemented. Secondly
BIM model managers ensured that all models are logically shared by all those
involved in the construction project, and coordinated throughout the project
lifecycle.
Intellectuals it seems had
predicted the kind of penetration BIM would have in the AEC industry and this
would have lead them to announce in a report way back in 2011, government
stated its objective that by 2016 it would need collaborative 3D BIM on all
government projects. The statement was the part of Government’s plan to
modernize the construction industry, with the absolute aim of achieving a 20%
cost cutting in construction and operation of new building. Significant to
attaining this goal is the employment of Building Information Modeling to
generate more effectual construction sector.
Conclusion
Like any new procedure,
change requires significant investment, particularly in an industry as divided
as building construction. The streamlined and savvy BIM process offers cost impoverishment
and change in the quality of construction. The sooner that building
construction companies focus on BIM, the more noteworthy the advantages will
be.
