Adopting BIM - An Architect's Perspective (07 May 2014)

  1. 1. 7 May 2014 London South Bank University An Architect’s Perspective Adopting BIM
  2. 2. Be Social #BIM #UKBIMcrew #Sustainability #Passivhaus @ElrondBurrell @ArchitypeUK @LSBU
  3. 3. Elrond Burrell Associate, Architype Ltd elrond.burrell@architype.co.uk
  4. 4. We design Life Enhancing" Genuinely Sustainable Architecture
  5. 5. Overview 1. The Context of BIM 2. Getting into BIM 3. BIM & Passivhaus
  6. 6. 1. The Context of BIM
  7. 7. BIM isn’t new!
  8. 8. Why now? 1. Software & Hardware capabilities 3d Modeling Structured Information Digital Collaboration
  9. 9. Why now? 2. Digital / Social Media ‘Tsunami’ Digital everything Social everything … will the construction industry catch up?
  10. 10. Why UK Gov + BIM?
  11. 11. EU Directive Energy Performance of Buildings Buildings consume 40% of energy in EU By 2018 All new public buildings “Nearly Zero-Energy” By 2020 All new buildings “Nearly Zero-Energy”
  12. 12. UK Gov Strategy
  13. 13. Mandated BIM
  14. 14. What is UK Gov BIM? “Building Information Modeling (BIM) is the process of generating and managing information about a built asset over its whole life.” Cabinet Office 2012
  15. 15. UK Gov Purpose 20% reduction in capital costs 20% reduction in CO2 emissions + reliable outcomes + predictable building (asset) performance
  16. 16. UK Gov BIM + GSL
  17. 17. BIM standards
  18. 18. BIM Protocols
  19. 19. 2. Getting into BIM
  20. 20. Observing Pre-BIM Duplicate working Designing in 3d, documenting in 2d CAD standards not always enforced
  21. 21. Proposing BIM Quick “proving exercise” Demonstration of key benefits Overcoming doubts & resistance to change
  22. 22. BIM Pilot Project Rules Small / Medium single storey Short duration Bland, not too creative Plan for pulling back to CAD
  23. 23. BIM Pilot Project Rules
  24. 24. Benefits Carefully manages risk, minimises potential losses Facilitate a gradual transition / learning Allows for easy comparison between projects
  25. 25. Risks No benefits of BIM gained No memorable experiences No mindset-shift
  26. 26. Following the Rules: “BIM is a RISK to be managed”
  27. 27. OR… No Rules? Large project, multi-storey Long duration Highly creative, challenging design Commit to BIM, no plan to pull back to CAD
  28. 28. Start! With a project that matters to your business
  29. 29. Benefits Maximises all available benefits of BIM Longer duration allows for learning & mistakes Exciting, interesting, engaging… the BIM mindset sticks
  30. 30. Risks Much more at stake that could go wrong High level of training & support needed Takes longer to see the results, harder to compare
  31. 31. No Rules “BIM is an OPPORTUNITY to be realised”
  32. 32. BIM vs CAD See: www.shoegnome.com/2012/10/15/how-bim-can-bankrupt-your-firm/
  33. 33. Don’t panic! See: www.shoegnome.com/2012/10/15/how-bim-can-bankrupt-your-firm/
  34. 34. Our Pilot Project
  35. 35. The Willows £17m / 6500sqm Lifelong learning campus Multiple clients Complex geometry 6 Phases, 10 Mineshafts
  36. 36. Ensuring Success Training / Support Project based bespoke training At desk training In-house expert (guess who?!)
  37. 37. Ensure Success The Team Tasks to suit abilities (not roles) Focus on LOD for outputs & outcomes Involve whole team in the real-world project
  38. 38. Results Stage D output in 4 weeks, reduced Stage E-F team 500+ drawing sheets,1355 unique views directly from the digital model Massive productivity gain Site RFI turn around in hours (not days!)
  39. 39. Bonus Results Unexpected use of the model Staff exceeding expectations Spread of BIM skills
  40. 40. 5 Stages of BIM 1.  Initial Excitement “Wow, Look what I can do with this thing!”
  41. 41. 5 Stages of BIM 2.  First Bump “Why won’t it do what I want? …It was easy in CAD!”
  42. 42. 5 Stages of BIM 3.  Creamy Middle “Things are going smoothly now”
  43. 43. 5 Stages of BIM 4.  WTF!? “Component Creation eats you up and spits you out”
  44. 44. 5 Stages of BIM 5.  Enlightenment “Things really click. You understand why things happen in the model, how to control them and how to avoid problems”
  45. 45. State of Mind vs Skill
  46. 46. State of Mind vs Skill
  47. 47. State of Mind vs Skill
  48. 48. Beyond the first project Internal uptake External demand The wider design team / Level 2 BIM
  49. 49. Bidding
  50. 50. LOD
  51. 51. Designing
  52. 52. Communicating
  53. 53. Almost Level 2
  54. 54. 3. BIM & Passivhaus
  55. 55. Passivhaus Standard “…the world’s leading standard in energy efficient design” Rigorous performance standard Quality assurance Optimal comfort (ISO 7730) Minimal energy Climate specific – works anywhere
  56. 56. PHPP: BIM or BEM? “simplified models, precise data” Accurate Open Parametric Instant
  57. 57. Data 4 QA Passivhaus can be seen as a quality assurance standard that ensure that the right information is used at the right point in the process to deliver reliable robust energy performance & comfort.
  58. 58. BIM + Passivhaus Process + Information + Model and test Not box ticking Not sexy graphics Not on site
  59. 59. BIM 4 Passivhaus Simple + Useful + Productive 1.  Visual interrogation 2.  Accurate Live Numerical Data
  60. 60. Visual Interrogation Design coordination / integration Thermal Continuity Heat Loss Envelope
  61. 61. Design Coordination
  62. 62. Design Coordination
  63. 63. Thermal Continuity
  64. 64. Thermal Bridges
  65. 65. Heat Loss Envelope
  66. 66. Accurate Live Data Treated Floor Area (TFA) Actual Volumes Ventilation Volumes Heat Loss Areas Window / Door Opening Areas
  67. 67. Areas and Volumes
  68. 68. Heat Loss Areas
  69. 69. Opening Areas
  70. 70. What does this deliver? 2 x 65kW Boilers for a 2200m2 School 25kW peak heat demand = 5x oversized! 90% reduction in gas consumption
  71. 71. Breathe easy!
  72. 72. “We feel that our children are more alert and attentive in lessons due to the amount of daylight in classrooms and the fresh air throughout the school ... learning has been enhanced” Sara Morris, Head Teacher Client Satisfaction
