Using Pictographic Instructions Derived from a Virtual Prototype to Support Construction Tasks

Tanyel Bulbul



The virtual prototype, like its real-world counterpart, is ultimately a model.  Prototypes are used to evaluate physical form, design concepts, performance characteristics and manufacturability prior to, or in lieu of building a real-world product. Three-dimensional imagery derived from a building information model (BIM) based virtual prototype can be used to non-verbally communicate constructability information. This presentation describes a study that investigates BIM supported virtual prototyping in AEC as an approach for constructability analysis and a communicator of production’s means and methods. The research has been conducted in two phases: the first phase includes a pilot test for defining the format of assembly information that needs to be extracted from the virtual prototypes. The second phase benchmarks a level of efficacy in non-verbal assembly instruction to support construction procedures. Real world construction of a small scale mobile laboratory for the Building Envelope Systems Technology research group is used as a case study for the research. The structure was assembled by novice university student-labor utilizing industrialized building materials in an indoor environment. Project documentation along with the construction assembly observations conducted during the Lab’s assembly provide data for this research, and presents a unique opportunity for examination of its constructability through graphical instruction.
