Abstract

N-dimensional building information and augmented reality modeling (nD BIM +AR) is the use of integrated multi-disciplinary performance models of design, construction, and operation to support project delivery objectives. This talk introduces the fundamental theories and methods of generating and representing nD BIM +AR models, and includes specific case studies of models, precise objectives, as well as detailed suggestions on how to implement them in practice. Particularly, four main aspects of these models for improving delivery of both building and civil infrastructure projects will be introduced and discussed: (1) model integration: how all project participants can access shared data, and a change in one component can change the dependent aspects of the integrated models; (2) multi-disciplinary coordination and collaboration: how these models facilitate coordination and collaboration among Architecture, Engineering, Construction, and Facility Management (AEC/FM) experts; and (3) performance models: how project performance (physical progress, quality, productivity, safety, and environmental impacts) can be sensed and analyzed using BIM and daily site photo/video logs; and finally (4) integrated visualization: how the expected and measured performance in relationship to stated project performance objectives can be represented and visualized in 4-dimensional augmented reality environments. The process of generating these models, and their perceived and actual benefits and limitations in improving business performance will be discussed in detail.
