BIM Definition4
2011; Government Construction Strategy2.32 Government will require fullycollaborative 3D BIM (with allproject and asset information,documentation and data beingelectronic) as a minimum by 2016A staged plan was published withmandated milestones showingmeasurable progress at the end ofeach year
5
The first BIM definition?“BIM as a modelling technology andassociated set of processes to produce,communicate, and analyse buildingmodels.”§ Building components§ Components that include data that
describe how they behave§ Consistent and non-redundant data§ Coordinated data
6
2011; Government Construction Client Group§ What is BIM?§ BIM is a managed approach to
the collection and exploitationof information across a project.At its heart is a computer-generated model containinggraphical and tabularinformation about the design,construction and operation ofthe asset

2014; Royal Institution of Chartered Surveyors
§ Building informationmodelling (BIM) getspeople and informationworking togethereffectively and efficientlythrough defined processesand technology
8
2015; Digital Built Britain§ ‘What is Building information
modelling?’§ Building Information Modelling
(BIM) is a collaborative way ofworking, underpinned by thedigital technologies whichunlock more efficient methodsof designing, delivering andmaintaining physical built assets
9
2016; BSI - British Standards InstitutionIn, created a BIM website to assistthe industry and defined BIM as“Building Information Modelling(BIM) is a collaborative way ofworking underpinned by digitaltechnologies. These technologiesallow for more efficient methods ofdesigning, delivering andmaintaining physical built assetsthroughout their entire lifecycle”.[5]
10
2016; National Building Specification§ BIM or Building Information
Modelling is a process forcreating and managinginformation on a constructionproject across the projectlifecycle
11
2017; EU BIM HandbookProbably the most recent, widely published,definition of BIM has come from the EU BIMHandbook
BIM is a digital form of construction and assetoperations. It brings together technology, processimprovements and digital information to radicallyimprove client and project outcomes and assetoperations. BIM is a strategic enabler for improvingdecision making for both buildings and publicinfrastructure assets across the whole lifecycle. Itapplies to new build projects; and crucially, BIMsupports the renovation, refurbishment andmaintenance of the built environment – the largestshare of the sector.

§ This standard is the bedrock of Level 1 andcovers two main areas§ Collaboration Management Processes§ Naming of Containers

We need todesign a frame
The framesolution is –
steel, concrete....
Do we build orrefurbish?

Traditional approach to analysis & design
A New Approach – Why is TSD different ?§ Fully 3D – not 2.5D, allowing users
to visualize and work with themodel in 2D horizontal (Floors)and 2D vertical (Frames)
§ Actual physical modelling ofmembers. E.g. Beams, Columns,Braces, Composite, Non-composite elements
§ This is important because?

Why standardised data?▪ Create data once, use it multiple times▪ Agree what data is really important when, and why▪ Define these requirements in the BIM procedures▪ Increase outreach for BIM as transformation from human
readable documents to machine readable structured data(informa on produc on → informa on consump on via CDE)
▪ Accelerate efforts on promoting and supportingimplementation of MVDxml and MVDs to support smoothworkflow in real projects
