Framework for shared visualization and real-Time information flow to the construction site

The aim of this paper is to develop a framework for shared visualization between design office and construction office using augmented reality as a platform with a focus on the security of Building Information Model. The current paper is part of an ongoing study aimed at creating a real-Time bi-directional information flow between the construction office and site and focuses on a shared visualisation context. A framework architecture for enabling shared visualisation with a stress on the security of Building Information Model is discussed. A prototype application based on the framework was deployed on an Android device in a controlled environment for testing. The application augmented Building Information objects dynamically to the real-world without any latency. Salient features of the prototype include dynamic loading of Building Information content during the runtime, data encapsulation based on user privileges, deployability on portable low-end computing devices etc. Using shared visualization would empower the construction engineers with real-Time models updates with access to many near-optimal management solutions. This enables the engineers to narrow in on the best solution under given constraints.
