IT rarely on Government construction agenda

2002 first time ICT seen as a cross-cutting issue(Accelerating Change)

2008 House of Commons Business & EnterpriseCttee: Construction Matters (but IT doesn't)

… Despite strong push from industry, eg: Constructing Excellence Construction Commitments National Platform for the Built Environment

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)

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)

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)

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)

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)

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!

BIM libraries

(some offering IFC objects)

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.”

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

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

33

The four levels of “BIM-wash”

confusion – inexperience – exaggeration – illusion

Bilal Succar (2011) Understanding BIM-wash
