Cost Time Resources Client Relations Employee Development Safety Cost Time Resources Client Relations Employee Development Safety Compared to shop welding, field welding is: Less safe More expensive More time-consuming Less efficient with resources workforce, materials, and energy

9. John Haymaker, CEE 214, 2009 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? Research Question Problem: The narrative structure is not formalized or managed. Result: AEC Projects are not achieving sustainable balance.

10. John Haymaker, CEE 214, 2009 Multidisciplinary, Constructive, Iterative, Unique The narrative structure of AEC projects narrative: “An account of a series of events, facts, etc., … with the establishing of connections between them.” (The Oxford English Dictionary)

11. John Haymaker, CEE 214, 2009 Narrative AEC professionals could benefit from a methodology to: Representation Reasoning Define task-specific representations. Define the dependency between these representations. Control the integration of these Narratives.
