presentation by Paul Wilkinson to CIMCIG BIM conference, Building Centre, London WC1 on Wednesday 25 April 2012.
Presentation explains what BIM is (and isn't), and outlines why it has become important in 2012, as the UK construction industry looks to meet a UK Government BIM deadline by 2016.
5. Online AEC collaboration (c. 2000s)
Online file management
Single central repository
Fewer interoperability issues
Less paper
Latest information
Complete project record
Full information audit trail
Greater re-use of information
But ...
nearly all still 2D
email often used instead

6. IT rarely on Government construction agenda
2002 first time ICT seen as a cross-cutting issue
(Accelerating Change)
2008 House of Commons Business & Enterprise
Cttee: Construction Matters (but IT doesn't)
… Despite strong push from industry, eg:
Constructing Excellence
Construction Commitments
National Platform for the Built Environment

7. BIM is not CAD
“CAD helps people to draw. BIM helps people to
construct.” (Richard Saxon, Ecobuild, February 2009)
“BIM is not CAD. BIM was never meant to be CAD.
CAD is a replacement for pen and paper, a
documentation tool. By comparison, BIM programs
are design applications in which the
documentation flows from and is a derivative of the
process, from schematic design to construction to
facility management.” (Pete Zyskowski, Cadalyst)
“Drawing is Dead – Long Live Modelling” (CPIC)

8. BIM is not ...
BIM is not
… new
… just an IT issue... or just software
… 3D
… something designers do
… just about project delivery
… a short-lived fad
… irrelevant to small projects
… “the silver bullet” or “Holy Grail”
… optional?

9. What is BIM?
Building Information Modelling is digital representation of
physical and functional characteristics of a facility
creating a shared knowledge resource for information
about it forming a reliable basis for decisions during its
life cycle, from earliest conception to demolition.
(definition: CPIC)

10. What is BIM?
Building Information Modelling
Building Information Model
Building Information Management
Hence BIM(M)

11. What is BIM?
Building Information Modelling is
… a business process for generating and leveraging
building data to design, construct and operate the
building during its lifecycle.
(NB: not just buildings, infrastructure, etc too)
11
12. What is BIM?
A Building Information Model is
... the output of the business process resulting in a digital
prototype, a virtual computer model of a project which
holds selected structured data about the asset (design,
quantity, time, cost, as-built, etc).
3D + time (4D) + cost (5D) + .... (nD)
12
13. What is BIM?
Building Information Management is
... the organisation and control of the business process
using the digital prototype to effect the sharing of
information over the entire lifecycle of an asset.
(NB: whole life approach)

14. Why is BIM important now?
2009
“... I need no
persuading [of] the
enormous potential that
lies in more intelligent
use of ICT...”
“... on my agenda … to
encourage the take-up
of existing and future
ICT tools...”
(ExtranetEvolution, December 2009)

27. OPEN BIM
launched March 2012
collaborative design, realisation and operation of
buildings based on open standards and workflows
founding partners
buildingSMART International (bSI)
vendors (eg: Tekla, Nemetschek, Graphisoft);
backed in UK by Constructing Excellence
using the open buildingSMART Data Model, IFCs
Poor interoperability cost US AEC industry $15.8bn
per annum (NIST, 2004) – mainly borne by owners!

29. What can we deliver with BIM?
UK Government aspiration:
“... reducing capital cost and the carbon
burden from the construction and operation of the
built environment by 20% ...
… the adoption of … technologies, process and
collaborative behaviours that will unlock new
more efficient ways of working at all stages of
the project life-cycle.”
29
30. What can we deliver with BIM?
Higher quality, more reliable design information
greater client certainty/predictability (time, cost,
quality) earlier
better visualisation
better multi-disciplinary collaboration
quicker, more consistent and easier coordination of
design documentation
earlier, accurate, complete procurement data
('smart' BoQs); elimination of waste and rework
better construction and project management ('build it
once virtually, then build it for real')
better 'as-built', whole-life information for O&M
30
31. What can we deliver with BIM?
Fully computable, reliable information
no checking or re-keying of data
automated compliance checking (Singapore)
“The end-to-end stream of BIM data will help
unify the industry's supply chains, freeing
construction from its craft origins, transforming it
into a modern, sophisticated branch of the
manufacturing industry.”
Ray Crotty (2011) The Impact of Building Information Modelling

32. Beware “BIM-wash”
Avoid inflated or deceptive claims of using or
delivering BIM services or products, eg:
BIM competency (individual, team, organisation) as
designers or contractors
BIM knowledge among IT implementation or
consultants and/or trainers
functionality/interoperability in BIM software
speed/capacity of hardware/comms used for BIM
quality of BIM library objects
BIM capabilities/needs as owner/operator
32
33. The four levels of “BIM-wash”
confusion – inexperience – exaggeration – illusion

BIM allows all stakeholders to have access to the same information at the same time through interoperability between technology platforms. The benefits include centralised and visual communication, early exploration of options, sustainability, efficient design, integration of disciplines, site control, as built documentation, etc. – effectively developing an asset lifecycle process and model from conception to final retirement.
