Alastair Gardner: BIM Overview

  1. 1. BUILDING INFORMATION MODELLINGConcepts and Reality, Implementation and RevitCCINW - Lancashire Construction Best Practice GroupAlistair Gardner ACIATASSOCIATE, senior architectural technician and cad managertaylor young|ty
  2. 2. Overview• Drivers For Change• BIM Overview• BIM Perspectives• BIM Enabled• Autodesk BIM & Revit Architecture• Revit Overview• ty examples – Oldham BSF / Preston College / West Notts’ College• BIM Future – iBIM/IPD• BIM- Implementation• Conclusions
  3. 3. Drivers For Change• 2D Environment / 3D world• Traditional problems• Sustainable design and energy performance compliance• Building performance regulation• Waste within construction• New technology• Best practice
  4. 4. BIM DefinitionsCharles (Chuck) Eastman, The BIM Handbook…“an intelligent simulation of architecture.” To enable us to achieve integrateddelivery, this simulation must exhibit six key characteristics. It must be:(a) Digital,(b) Spatial (3D),(c) Measurable (quantifiable, dimension-able, and query-able),(d) Comprehensive (encapsulating and communicating design intent, building performance, constructability, and include sequential and financial aspects of means and methods),(e) Accessible (to the entire AEC/owner team through and interoperable and intuitive interface, and(f) Durable (Usable through all phases of a facilities life).
  5. 5. BIM DefinitionsBS ISO 29481-1 2010 - Building information modelling - Information delivery manual“Shared digital representation of physical and functional characteristics of anybuilt object (including buildings, bridges, roads, etc.) which forms a reliable basisfor decisions” CPIC /RIBA – Proposed Definition “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.”

  9. 9. BIM OverviewAEC (UK) BIM Standards For Revit – Shared Environment
  10. 10. BIM Advantages - General Benefits• Enhanced Design• Greater Productivity• Improved Delivery
  11. 11. BIM Advantages – Designers• Conceptual design• Central Source of information• Multi-Discipline Integration• Early detection of conflict
  12. 12. BIM Advantages - Construction• Pre-construction assessment• Reduction in no. of RFIs• Fewer field coordination issues• Quantity/cost tracking improvements• Greater potential for off-site fabrication• Reduce Risk
  13. 13. BIM Advantages – FM Advantages• Asset management• Facility maintenance and operation• Life cycle of buildings• Single Source of Information• BIM virtual building and FM Software synchronisation
  14. 14. BIM -Reality• BIM seen as an obstacle not an enabler• We are adapting BIM to fit current practices• ‘My’ BIM• Varied Adoption• Software collaboration needs to Improve• Definition of BIM is not important it is about understanding what BIM Enabled Technology can do for you.• We need to understand BIM Better
  15. 15. BIM Enabled Technology – ‘Architecture’ BIMBIM technology is being developed by a range of major CAD vendorsbut is represented by three main staples for Architecture; Revit Suite NavisWorks Grahisoft Archicad Vecterworks All-Plan Microstation Bentley Architecture Many More BIM packages for Environmental and Structural analysis
  16. 16. BIM Enabled Technology – ChoiceNBS Survey 2010 – Current Primary Drawing Tools
  17. 17. BIM & Revit Architecture• Exhibits all the key attributes of BIM• Chosen BIM Package of ty• Core Product Split For Design Disciplines MANAGE • Revit Architecture CONCEPTUALISE • Revit Structures COLLABORATE • Revit MEP DESIGN ANALYSE• ty Implementation projects seeing the real benefits of BIM VISUALISE FABRICATE DOCUMENT SIMULATE

  19. 19. Project Examples – Preston CollegeAdvantages• Single Source of Information• Co-ordination with structural consultants.• Able to produce drawn information quickly at any point of the building• Phasing Options• Integrated Detailing• Links to Environmental AnalysisDisadvantages• Not all consultants were using BIM• Software specific learning curves • Drawing Co-ordinate – Project / Shared systems • Massing issues
  20. 20. Project Examples – Preston CollegeKey Advantages – In-built Phasing
  21. 21. Project Examples – Preston CollegeKey Advantage – Structural Frame Co-ordination
  22. 22. Project Examples – Preston CollegeKey Advantages – Linked Detailing

  24. 24. Project Examples – Oldham BSFAdvantages• BIM Implementation project• Single source of information – Co-ordination• Ability to adapt design during all stages• Able to produce drawn information quickly• Automated schedule / take off• Worksharing environment• Contractor using BIM for Co-ordinationDisadvantages• Consultants were not using BIM• Software specific learning curves • Object Level Assignment • Room object association
  25. 25. Project Examples – Oldham BSFAdvantages – 3D Environment & Rendering

  27. 27. Project Examples – West Notts CollegeAdvantages• BIM Refurbishment Implementation project• Single Source of Information• Phasing Option• Able to produce drawn information quickly at any point of the buildingDisadvantages• Consultants were not using BIM• Contractor not using BIM• Software specific learning curves • Phasing of objects

  29. 29. iBIM / Integrated Project DeliveryBIM DefinitionChuck Eastman, The BIM Handbook Circa…“an intelligent simulation of architecture.” To enable us to achieve integrateddelivery“BIM alone fails to achieve a truly Common Shared EnvironmentOnly when we have a proper working understanding of BIM will we be able tobegin the next step of integrated BIM (iBIM) and Integrated Project Delivery (IPD)
  30. 30. iBIM /IPD OverviewCPIC - Construction Project Information Committee –2010 BIM Workshop - Principles of CAD evolution Levels 0-3
  31. 31. Conclusion - Why use BIM?• Improve design quality• Improve communication• Single source of Information• Co-ordination• Increased collaboration with partners• Reduction in waste• Opportunities for re-use of data post construction• Future Possibilities
  32. 32. BIM – Implementation• Planning Implementation Is key • Develop a sound, comprehensive implementation strategy, • Assemble the right team, • Select a suitable starting project• Understand the learning curves• Understand Cost and Benefits to business• ROI –calculators• Hardware requirements
  33. 33. Conclusions• Industry needs to establish a clear best practice with BIM• More Open about current BIM adoption• BIM definition is not important it is about understanding the benefits of a BIM Enabled Environment• Once we are BIM enabled then we can move to Social and iBIM• Working procedures need to adapt to enable iBIM/IPD• Real risk that not having BIM experience could exclude you from future projectsThe introduction of BIM is not about the adoption of any software; it is probablythe most significant operational change process you will ever make
