Huge progress has been made on 'Augmented Reality' (AR) techniques such as registration, tracking, and display hardware. However, a construction AR system should be more convenient and combined with in-use applications to support multi-disciplinary users throughout construction lifecycle. This paper presents a video-based on-line AR environment and a pilot cloud framework. The contribution lies in two aspects: firstly, an environment utilizing web3D is demonstrated, in which on-site images are rendered to box nodes and registered with virtual objects through a three-step method; secondly, it is further extended to be "cloud" through federation of BIM (building information modeling) and BSNS (business social networking services). Technical solutions to key issues such as authoring, publishing, and composition are designed. The proposed environment is seamlessly integrated into in-use information systems and therefore enjoys greater usability. Implementations demonstrate how this framework and environment work. Although preliminary, it is conclusive for proof of concept. © 2012 Elsevier B.V.

The capabilities of applying smart information management systems for facility management (FM) in oil refining context have not yet been fully exploited. This paper presents a study that investigates the applicability of integrating advanced technologies such as augmented virtuality (AV), augmented reality (AR), and server-sustained information modeling (IM) in facilitating FM activities for a petroleum refinery. The paper starts with a thorough review on previous work in which multiple information processing technologies are applied to aid FM. The following section presents the conceivable merits when the novel visualization is formulated to enhance the conventional IM application. It then proposes a novel system framework based on technological feasibility and further describes the development of a system prototype that boosts immersive and interactive experiences to FM toward a multitude of electrical components. It is noted that this paper focuses on the method for the technological realization of the system. With the successful development of the system, it is able to deal with the management of complex information flows, support the users' navigation in geo-coordinates, and enables a succinct smart IM interface with switchable AV/AR scenes. In view that IM has been proved suitable in supporting real-time communication and information management while AV/AR can be effectively used to improve the way how information is exhibited into real workspaces, the system proves the concept of IM+AV/AR in the context of FM in a refinery. Future work will be conducted on the evaluation of system effectiveness and system optimization, with the aim of functional improvement and performing a feasibility study. © 2013 IEEE.

The problem of data integration throughout the lifecycle of a construction project among multiple collaborative enterprises remains unsolved due to the dynamics and fragmented nature of the construction industry. This study presents a novel cloud approach that, focusing on China's special construction requirements, proposes a series of as-built BIM (building information modeling) tools and a self-organised application model that correlates project engineering data and project management data through a seamless BIM and BSNS (business social networking services) federation. To achieve a logically centralised single-source data structure, a unified data model is constructed that integrates two categories of heterogeneous databases through the adoption of handlers. Based on these models, key technical mechanisms that are critical to the successful management of large amounts of data are proposed and implemented, including permission, data manipulation and file version control. Specifically, a dynamic Generalised List series is proposed to address the sophisticated construction file versioning issue. The proposed cloud has been successfully used in real applications in China. This research work can enable data sharing not only by individuals and project teams but also by enterprises in a consistent and sustainable way throughout the life of a construction project. This system will reduce costs for construction firms by providing effective and efficient means and guides to complex project management, and by facilitating the conversion of project data into enterprise-owned properties.© 2012 Elsevier Ltd.

This review focuses on identifying the impacts and future development trends for current structural design practice in integration of building information modelling (BIM) technologies. BIM technologies, as novel information management schemes they are, are changing the conventional structure design processes. Currently, utilising BIM technologies for reshaping structural design has been widely acknowledged and embraced by both academic and industry circles. In this research, the current status and issues of the structural design processes (including modelling, analysis, and optimisation of structures) are fully investigated with emphases on specific design stages. The research put efforts on surveying the benefits of BIM in facilitating current structural design, such as systematic modelling processes, powerful interactive visualization platform, and standardised exchanging data interfaces. Impacts of personnel involvement in structural design when adopting BIM have also been identified in detail. Finally, a predicted cross-functional flowchart of BIM-enabled structural design for the near future is proposed, which shows future developing trends in improving structural design quality and addressing current issues. © 2014, CIMNE, Barcelona, Spain.
