BIM – What is it??

• Process

• Data plus 3d model

• Different Levels of BIM

BIM – What is it good for?

• Clash Detection– One of the most important aspects of BIM– Final model a composite of different disciplines

http://www.thenbs.com/

BIM – What is it good for?

• Clash Detection

• 8D????– Standard 3D– Time– Money– Facilities Management– Sustainability– Occupational Safety & Health

BIM – What is it good for?

• Clash Detection

• 8D????

• Cost saving– £40 million is spent on Centrally Funded Public buildings

• 30% construction process is rework• 60% of labour effort is wasted• 10% loss due to wasted materials• 3-5% construction turnover lost due to non-interoperability

– Early demonstrations projects achieved• 20% saving during construction• 33% saving over life of building

– Lower Insurance Premiums

BIM – What is it good for?

• Clash Detection

• 8D????

• Cost saving

• Energy– Energy tags eg circuit loadings etc can be applied to families– Works with several energy analysis packages eg Green Building Studio,

eQUEST, Ecotect Analysis, CFdesign

BIM – What is it good for?

• Clash Detection

• 8D????

• Cost saving

• Energy

• Intelligence behind the model– Geometry & data adjustable within building & within families– Geometry can be linked or attached to each other– Can be linked to schedules within the model.

BIM – The Nasty Bits

• Cost– Licence – updates yearly– Hardware– Training

BIM – Opinions

• Experience from an Architect– 100% projects done with BIM– Less labour intensive– Model owned & maintained by Architect– Only responsible for own content

– Cost & training– Quick to get to where advance training needed– Software & implementation moves quickly– Back saving to earlier version– Scheduling

• COBie• Many stalling due to cost & general confusion• Visualisations were main driver – real time rendering a big sell.

BIM – Who is using it?

• Heathrow Terminal 2B

• Companies involved– Balfour Beatty– WSP– Mott McDonald– Grimshaw Architects LLP– One Point Design– Parsons Brinkerhoff– Exova Warrington

• Software used– AutoCAD Architecture Design– Revit Structures 2011– CADduct 2012– Navisworks– Primavera

Institute of Civil Engineers – Heathrow Terminal 2Bhttp://www.ice.org.uk/topics/BIM/Case-studies/Heathrow-Terminal-2B

BIM – Future

• BIM Level 3– A fully open process and data integration enabled by common readable

formats managed by a collaborative model server. This could be regarded as iBIM (intuitive BIM) or integrated BIM potentially employing concurrent engineering processes.

BIM – Future – but right now

• Standards – asset management, COBie etc– PAS 1192-2: Specification for information management for the

capital / delivery phase of construction projects using building information management

– PAS 1192-3:Specification for information management for the operational phase of assets using building information management

– Definitions• EIR – employers information requirements• CDE – common data environment• AIM – asset information model• PIM – project information model• PLQ – plain language questions

BIM – Future – but right now

• Standards – asset management, COBie etc

• Definitions are changing

BIM – Future – but right now

• Don’t kid yourself– Level 0 – 3%– Level 1 – 15%– Level 2 – 60%– Level 3 – 22%

BIM – Future – but right now

• Looking past 2016 to Government Construction 2025 Strategy.– 33% lower costs– 50% faster delivery– 50% lower emissions– 50% improvements in exports

BIM – Future – but right now

• Looking past 2016 to Government Construction 2025 Strategy.

• BIM Level 2 Certification schemes
