The management of complex information flow can be a crucial aspect of Facility Management (FM). Because of the increasing complexity of the present-day building projects, FM activities, for example, maintaining a building facility or a system, normally involve enormous human multitasking across different knowledge domains. Lessons learned from the present successful FM instances manifest that the FM teams are increasingly interested in applying more viable technologies to achieve the effective management of massive information. Building Information Modelling (BIM) technology is one of the promising approaches, as it forms a platform for the users to manage the information of a facility and leverages virtual digital representations as a reliable basis for decisions during its life-cycle. Nevertheless, the fully immersive environments produced by BIM still lack the capability of mapping a virtual world into a real world, or vice versa. Augmented Reality (AR) is emerging as an advanced visualization which is possible to bridge the gap. It enables the demonstration of BIM context into the real world, and is envisaged to effectively improve the way of how information is displayed. Meanwhile, the virtuality-toreality changeover from BIM to AR is conductive to a better understanding of information about a facility from the human perception perspective. The objective of the study is to explore that the merging of AR with BIM is a way for improving the information search and management in FM applications. This chapter firstly brief what is FM and how it is generally implemented. Followed by the state-of-the-art review of BIM/AR aided FM research, the chapter then proposes the viability of integrating BIM and AR and demonstrates its efficacy of processing complex onsite information based on four BIM+AR case studies. Finally, the chapter discusses the technological transferability issues in terms of deploying more and more BIM+AR scenarios in the prospective FM process.

“…Benbelkacem et al [16] focused on synchronous and remote collaboration between technicians and experts to complete maintenance and repair tasks by giving augmented information on the user's field of view. Two principal concepts are treated and developed: remote collaboration based on Web Services and virtual objects transfer.…”

Product maintenance is a knowledge intensive task. With the increasing complexity of modern large scale products, the maintenance process usually is carried out collaboratively by onsite technicians and remote experts. Augmented reality provides a novel interactive way for collaborative maintenance work. In an augmented instruction scene, the real maintenance product is combined with visual information and thus helps the technician to understand the process, which will be more efficient than traditional maintenance manual or oral words. In order to reduce the data quantity transferred between the local technician site and remote expert site, a framework of augmented reality based collaborative maintenance real-time instruction platform under network environment is proposed to achieve efficiently guidance from remote expert. The augmented information for maintenance process instruction is classified and their visualization methods are realized. During the collaborative maintenance process, the instruction information is shared based on different patterns. A prototyping system is developed for onsite technician and remote expert. The augmented collaborative maintenance process instruction is illustrated by replacing an air filter of an auto engine.

“…There are currently several works in the literature that use this technology for that purpose (e.g. [2], [3], [4]). However, the main output of those works is usually one prototype that is used in one case only which implies a lack of a reusable general purpose Augmented Reality-based maintenance system which is usually required in industrial environments [5].…”

A New Flexible Augmented Reality Platform for Development of Maintenance and Educational Applications

Augmented Reality (AR) is a technology that has gained an increasing interest during last years. Several fields (e.g. maintenance and education) have already started to integrate AR systems in their procedures. The preliminary results obtained from those works show a promising future for the technology. However, the number of tools that allow non-programmers to create new applications is still limited. Moreover, the great majority of these tools have still some limitations in terms of flexibility and reusability. The purpose of the platform presented in this paper is to face those problems and provide new means of AR application development. The main target of the platform is to serve as a unified system for aiding operators in the maintenance procedures in large scientific facilities. However, an important goal is that the platform can be flexible enough so it can be adapted to other fields. In order to demonstrate this flexibility, the platform has been also used to develop educational applications and a commercial educational platform.
