BIM – What is it??
• Process
• Data plus 3d model
http://www.microcad.co.uk
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 – The Nasty Bits
• Cost
• Personnel
• Saving backward– Versions– Maintenance & upkeep– Maintenance on long projects
BIM – The Nasty Bits
• Cost
• Personnel
• Saving backward
• Confusion– Driving force– Responsibility– Ownership
BIM – The Nasty Bits
• Cost
• Personnel
• Saving backward
• Confusion
• No protection– Watermark– Add company name– Materials
BIM – The Nasty Bits
• Cost
• Personnel
• Saving backward
• Confusion
• No protection
• COBie– Construction Operation Building information exchange– BIG spreadsheet– IFC– Incorporated in BS 1192

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 – 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

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
