  1. Narratives Narrative Reasoning Representation Narratives : A simple, formal methodology for achieving sustainable balance John Haymaker, PhD, AIA, LEED cp Collaborators: Martin Fischer, John Kunz, Ben Suter M.A. Mortenson, Walt Disney Imagineering, CCC, Gehry Partners, William McDonough Partners, CSIRO

  2. A William McDonough Partners design process Define regulatory requirements Analyze Productivity and Absenteeism Analyze first cost Analyze daylight Analyze energy Propose traditional Analyze life-cycle cost Define client requirements Propose atrium Define site Decide on Atrium

  3. A William McDonough Partners design process Define regulatory requirements Analyze Productivity and Reliability Analyze first cost Analyze daylight Analyze energy Propose traditional Analyze life-cycle cost Define client requirements Propose atrium Define site Decide on Atrium Analyze Define Goals Propose Options Perform Analyses Evaluate Goals

  4. Did WMP achieve sustainable balance? WMP found it difficult to explicitly: Propose many options Analyze these options Compare their analyses to their goals Clearly communicate this design process Quickly integrate this design process

  5. A Walt Disney Concert Hall design & construction process

  6. This process was time-consuming and error-prone.

  7. SI-13 This process was iterative.

  8. Did the WDCH team achieve sustainable balance? Safety Cost Safety Cost Employee Development Time Employee Development Time Client Relations Resources Client Relations Resources Compared to shop welding, field welding is: Less safe More expensive More time-consuming Less efficient with resources workforce, materials, and energy

  9. Research Question Problem: The narrative structure is not formalized or managed. Result: AEC Projects are not achieving sustainable balance. What is a methodology that enables AEC professionals to formalize the dependencies among their representations, and control the integration of these representations as the project progresses?

  10. The narrative structure of AEC projects Multidisciplinary, Constructive, Iterative, Unique narrative: “An account of a series of events, facts, etc., … with the establishing of connections between them.” (The Oxford English Dictionary)

  11. Reasoning Reasoning Reasoning Reasoning Representation Narrative Define task-specific representations. Define the dependency between these representations. Control the integration of these Narratives. AEC professionals could benefit from a methodology to:

  12. Reasoning (automated) Reasoning (manual) Representation dependency Representation data Narrative data relationship Narratives

  13. POD: AEC project model frameworks COMBINE (Augenbroe, 1995) EDM-2 (Eastman et al 1999), Graphisoft (Sawyer, 2004) Bentley Managed Environment (Hollings, 2003) No formalization of distributed and narrative process

  14. Prevalent approach Narrative approach POD: AEC project model frameworks

  15. POD: Representation formalisms Representation IFC STEP gbXML Revit Reasoning No formalization of the process or dependency

  16. Energy Simulation (Riuska) Comfort Simulation (Riuska) Construction Simulation (Commonpoint) Structural Simulation (SAP2000) Space Analysis (Solibri) Steel Detailing (Tekla) Egress (Pan et al 2004) Life Cycle Analysis (CRC) Cost Analysis (Tocoman) Daylight Simulation (Radiance) Reasoning No formalization of the process or dependencies Representation POD: Reasoning

  17. POD: Process models Reasoning No formalization of representations or reasoning Representation

  18. Narratives: Building on Points of Departure Reasoning Representation Narratives Process
