There are many questionnaire surveys
are carrying out related to BIM, by the under graduate students who are
studying the quantity surveying, building economics, construction management…
etc. These questionnaire surveys I used to received from ‘LinkedIn’, but I do
not have any idea about BIM. I have got an article about BIM, which is prepared
by RICS. The same I shared here and I hope this will be a useful document to
all.
Before, there are some sentences
about RICS.
Royal Institute of Charted Surveyors
(RICS)
RICS is the
world's leading qualification when it comes to professional standards in land,
property and construction.
In a world
where more and more people, governments, banks and commercial organizations
demand greater certainty of professional standards and ethics, attaining RICS
status is the recognized mark of property professionalism.
Over 100,000
property professionals working in the major established and emerging economies
of the world have already recognized the importance of securing RICS status by
becoming members.
RICS is an
independent professional body originally established in the UK by Royal
Charter. Since 1868, RICS has been committed to setting and upholding the
highest standards of excellence and integrity - providing impartial,
authoritative advice on key issues affecting businesses and society. RICS is a
regulator of both its individual members and firms enabling it to maintain the
highest standards and providing the basis for unparalleled client confidence in
the sector.

Building Information Modeling (BIM)
Building Information Modeling (BIM)
is both a new technology and a new way of working. BIM is a term that has been
around for a while in manufacturing and engineering industries, and is now beginning
to make an impact in the construction sector. At a strategic level, BIM offers
the capacity to address many of the industries failings including waste reduction,
value creation and improved productivity.
The process of implementing BIM moves
away from using conventional word-processing and CAD into the increased use of
common standards and product orientated representations. BIM changes the
emphasis by making the model the primary tool for documentation, from which an
increasing number of documents, or more accurately “reports”, such as plans, schedules
and bills of quantities may be derived.
BIM involves much more than simply
implementing new software. It is a different way of thinking. This requires a
move away from the traditional workflow, with all parties (including
architects, surveyors and contractors) sharing, and effectively working on, a
common information pool. This is a substantial shift from the more traditional
convention where parties often work on separate information pools using several
different (and usually incompatible) software packages. In essence, BIM
involves building a digital prototype of the model and simulating it in a
digital world.
Essentially, BIM combines technology
with new working practices to improve the quality of the delivered product and
also improve the reliability, timeliness and consistency of the process. It is equally
applicable to asset and facilities management as it is to construction. In its
purest form, BIM provides a common single and coordinated source of structured
information to support all parties involved in the delivery process, whether
that be to design, construct, and/or operate. Because all parties involved with
a BIM project have access to the same data, the information loss associated with
handing a project over from design team to construction team and to building
owner/operator is kept to a minimum.
A BIM model contains representations
of the actual parts and pieces being used to construct a building along with
geometry, spatial relationships, geographic information, quantities and properties
of building components (for example manufacturers’ details). BIM can be used to
demonstrate the entire building lifecycle from construction through to facility
operation.
Often (mistakenly) referred to as 3D,
4D or nD, BIM should not be confused with the number of dimensions used to
represent a building. At its simplest level, BIM provides a common environment for
all information defining a building, facility or asset, together with its
common parts and activities.
This includes building shape, design
and construction time, costs, physical performance, logistics and more. More
importantly, the information relates to the intended objects (components) and processes,
rather than relating to the appearance and presentation of documents and
drawings. More traditional 2D or 3D drawings may well be outputs of BIM, however,
instead of generating in the conventional way ie. as individual drawings, could
all be produced directly from the model as a “view” of the required
information. BIM changes the traditional process by making the model the primary
tool for the whole project team. This ensures that all the designers,
contractors and sub contractors maintain their common basis for design, and
that the detailed relationships between systems can be explored and fully detailed.
Working with BIM will require new skills and these will have to be learned from
practice.
BIM is not a panacea – it remains
just as possible to produce a poor model, in terms of its functionality, its
constructability or its value, as it is to produce poor drawings, schedules or
any other, more traditional, form of information. Also, in the absence of any
pro-active collaborative management effort, models may end up being prepared to
suit the originator as opposed to being structured and presented with all
parties to the design and construction team in mind. Ensuring that there is an
agreed structure and exchange protocol in place to suit all parties will
improve certainty, confidence and consistency. By moving to a shared
information model environment, project failures and cost overruns become less
likely. BIM certainly means having a better understanding and control of costs
and schedules as well as being able to ensure that the right information is
available at the right time to reduce requests for information, manage change
and limit (or even eliminate) unforeseen costs, delays and claims.
Clients are often in the best
position to lead the introduction of BIM. Understanding the value of building
information and its impact on the clients own business is leading many clients
to require BIM to specify the standards and methods to be used in its adoption.
Clients can also provide clear requirements for facilities management
information to be handed over at project completion more easily with BIM. Some
international clients are even now going so far as to penalise lack of information
(or the lack of its provision at established points in the construction
process).
More recent experience indicates a
trend in large clients and government agencies across the globe to mandate the
use of BIM, not only for delivery of the building, but also as a tool to manage
operationally. BIM is equally applicable to support FM and asset management as
it is to design and construction. Indeed, the output of the design model may
well replace the need for traditional O&M manuals. Being able to interrogate
an intelligent model, as opposed to searching through outdated manuals, perhaps
linked to interactive guidance on the repair and/or maintenance process has obvious
advantages.
However, the largest single barrier
to exploiting BIM is the lack of awareness. Clients are frequently unaware that
they can have a major influence on the deliverables from a project.
BIM has the potential to impact every
aspect of the Surveying Profession. It has applications for those involved with
Property, FM, Building Surveying, Civil as well as traditional building construction,
and should be seen as an opportunity to deliver new service streams and to
extend our professional reach into new areas spanning the complete asset life
cycle. BIM is not going to go away, and so we must, therefore, learn to adapt
and embrace or risk the threat of losing ground to others.
I will share one more article about BIM (
BIM
is key to future of QS profession).
