“…These markers are recognized in real-time and used as a reference object to precisely superimpose virtual 3D content onto the camera's live view. The fiducial markers are rectangular 2D markers with a fixed structure and distinctive black border that can be easily and very robustly detected and tracked (KOCH et al, 2014). The picture marker is an arbitrary borderless image (containing enough visual content) that can be robustly detected and tracked.…”

Abstracthis article presents the development of an Augmented Reality (AR) application to assist in the assembly of a precast wood-frame wall, based on the BIM model of the wall execution sequence. The research study used the Design Science Research approach and its aim was to develop an AR application named "montAR" (version 2.0). This application offers a tutorial that combines a wall model visualized in AR in actual scale, followed by an audio with step-by-step instructions of the assembly process. Its applicability was simulated in a laboratory with the participation of volunteers (architecture and engineering students). Two visualization gadgets were used and compared: smartphones and smart glasses. The potentialities and difficulties of the use of the AR system were assessed through a questionnaire answered by the participants and through direct observation and result analysis by the researchers. The results demonstrated the potential of using AR for precast wall assembly. From a technological innovation perspective, this study emphasizes the potential use of AR as a technology suitable for training and for construction quality control.Keywords: Augmented Reality.

ABSTRACT:Today technological developments in the Architecture Engineering and Construction (AEC) industry provides opportunities to build huge and complex buildings and facilities. In order to operate these facilities and to meet the requirements of the occupants and also to manage energy, waste and to keep all facility services operational, several Facility Management (FM) solutions were developed. This paper starts by presenting a state of art review of research related to Indoor Facility Management Systems. Later, a textual analysis focused to identify the research trends in this field is presented in the paper. The result of the literature review and textual analysis indicates that current research in Indoor FM Systems is underestimating the role of Geoinformation, Geoinformation models and systems.

“…One of the most interesting and important progress is given by the introduction of the Augmented Reality (AR) in the asset management world: software companies [19][20][21] and researchers [13,[22][23][24] developed various software and plugins to allow maintenance operators to interact with the building with tablets, smartphones, or even smart glasses. These solutions enable users to query, identify, and enrich objects, by remotely modifying the BIM model contained in a server.…”

A National Institute of Standards and Technology (NIST) study shows that all stakeholders in the capital facilities industry waste a huge amount of money looking for, validating, and/or recreating facility information that should be readily available. The total cost of these activities within the capital facilities industries in the United States was conservatively estimated at $15.8 billion in 2002, with two-thirds of that cost occurring during the facilities' operations and maintenance phase. This is confirmed by the International Facility Management Association (IFMA) Maintenance Survey in 2009, which states that the loss of information generates an added cost of 12.4% of total annual mean O&M costs. Nowadays, standards and specifications have been developed about availability, integrity, and transfer of data and information during the operational phase of an asset life. PAS 1192-3, among these, suggests the use of Building Information Modeling (BIM) models to store and access facility information, but the turning point is the ability to provide different stakeholders with different data, which should be targeted to them, easily accessible, readable, and updatable (and up to date). This research started with the collection of asset managers' needs and then the definition of new procedures for assets and facility management in a BIM-based workflow focusing on how to allow users to access, use, and update facility data stored in a BIM model without a BIM authoring tool. Examples are shown for: (1) management of rooms occupancy; (2) management of mechanical equipment status; (3) qualitative condition assessment of buildings; and (4) appraisal of the service life of building components and systems according to ISO 15686-8. These four tools allow to compute and control some key indicators of the asset, with also the possibility to compare them inside a portfolio. This paper presents the four tools, paying also attention to the workflows to be followed and to the different data needs of the stakeholders involved.
