By sharing and managing the database for a building model, Building Information Modeling (BIM) facilitates the design process at less cost. Some of BIM software has capabilities for acoustical analysis, but it is limited to noise level demonstration of MEP system in a building. Sophisticated acoustical analysis programs, such as EASE and CATT provide the useful parameters to determine the sound quality of a space with graphs, A/V systems, material database, and auralization. This research explores how BIM with discipline-specific data reinforced with acoustical information will be beneficial to both architects and acousticians, by allowing them to communicate efficiently. The design process for a performing arts hall is used to demonstrate how to interoperate between BIM system and acoustical analysis programs. Revit Architecture and EASE program are used as design and analysis tools for the project. A model is developed to improve the process of embedding acoustic information in BIM and sharing knowledge in an integrated delivery process.

The rapid development and adoption of AR applications creates numerous opportunities for integrating AR with BIM and improving conventional methods used in the fields of architecture, engineering, and construction (AEC). In this chapter, the current trends in the development of AR applications and the application of AR technologies in the fields of AEC are proposed. Also, the relation between AR application and BIM in the AEC industry with the benefits of this integration and possible issues is discussed. The related examples of BIM+AR are described during the literature review. The authors believe the papers presented in this document cover the latest research trends and developments in the use of AR and its combination with BIM for AEC applications. In the future, it is expected that AR applications will be further utilized in the AEC field to enhance productivity, safety, and efficiency.
