Augmented Reality Applied to Building Assessment with Building Information Model Visualization

Abstract

AR (augmented reality) is a technology that adds information to the real world adding virtual elements to its visualization in real time. AR used in AECO (architectural, engineering, construction and operations) can contribute in augmenting visualization during design, construction and operation of the buildings. This article presents a study that applies AR to building assessment with BIM (building information) model visualization. The use of AR on existing applications for smart phones and tablets is validated. AR proposed an adaptation of the method of POE (post-occupancy evaluation) subsidized. Traditional POE process model involves three phases: planning, conducting and applying. In order to incorporate AR, it is proposed a total restructuring of the planning phase, developing the research instruments in three steps: 3D modeling, model treatment and AR application development. It was observed that for POE studies, the 3D models are in large scale and need to be detailed for precise comparison. BIM models for facility management, representing building use situation, are of the highest level of detail. A balanced point between simplicity and representativeness was the solution adopted in this experiment for uploading and downloading performance issues. This article presents and discusses findings for the new proposition for the activity of research instruments development for the planning phase of POE with AR as well as initial tests with first results and difficulties faced.
