“…The authors state that their approach will improve the quality of the final manufactured products by reducing the offset distances and ensuring that are within the tolerance levels. Fazel and Izadi (2018) presented an AR system that supports construction workers to construct complex double-curved brick walls. The presented system uses a marker-based approach, in which a camera tracks two markers, one located on the floor and another one on the worker's HMD.…”

Augmented and virtual reality have the potential to provide a step-change in productivity in the construction sector; however, the level of adoption is very low. This paper presents a systematic study of the factors that limit and drive adoption in the construction sectorspecific context. A mixed research method was employed, combining qualitative and quantitative data collection and analysis. Eight focus groups with 54 experts and an online questionnaire were conducted. Forty-two limiting and driving factors were identified and ranked. Principal Component Analysis was conducted to group the identified factors into a smaller number of factors based on correlations. Four types of limiting factors and four types of driving factors were identified. The main limitation of adoption is that AR and VR technologies are regarded as expensive and immature technologies that are not suitable for engineering and construction. The main drivers are that AR and VR enable improvements in project delivery and provision of new and better services. This study provides valuable insights to stakeholders to devise actions that mitigate the limiting factors, and that boosts the driving factors. This is one of the first systematic studies that presents a detailed analysis of the factors that limit and drive adoption of AR and VR in the construction industry. The main contribution to knowledge of this study is that it grouped and characterized a myriad of limiting and driving factors into easily understandable categories; so that, the limiting factors can be effectively mitigated, and the driving factors potentiated. Also, a roadmap with specific short term and medium-term actions for improving adoption has been outlined.

“…In this sense, improving the recognition of markers through image pre-processing should be considered (Kwon et al, 2014). Also, the calibration of the camera must be precise, to obtain the alignment in the images (Fazel & Izadi, 2018). Figure 4 presents a comparative analysis of the most used tracking technologies: Table 4 and Figure 4 present the technologies applied in the investigations conducted between 2008 and 2018.…”

The need for systematic data collection and processing to generate real-time building site progress information is critical. Building Information Modelling (BIM) provides the benefit of aggregating information about the building site on a single platform. Augmented reality (AR) emerges to enhance BIM concerning visualization of the building site, through processing and automatic absorption of information. This work aims to analyse the potential of AR association to BIM, by adopting an approach based on literature review. Trends in contemporary research are checked by categorizing applied research methods, areas of expertise, and AR technologies. Publications produced between 2008 and 2018 from journals of architecture, engineering, and construction areas in databases Web of Science, SciSearch, SCOPUS, INSPEC, Google Scholar, Academic OneFile, EBSCO, OCLC, VINITI, SCImago, and ProQuest were investigated. As main results, it was found that the case study approach was adopted in 41% of the publications analysed. The building site inspection was the research object in 48% of papers. Fiducial markers, GIS/GPS, laser scanners, and photogrammetry emerged as main options for automatic data capture on the progress of the building site. Integration between AR and BIM has the potential to solve information processing problems and improving construction management.

“…Already in the mid 90´s researcher visualized invisible infrastructure like load bearing columns and their structural analysis using a head worn display [14]. In more recent research, Fazel and Izadi used a head mounted display to guide the manual construction of complex architectural freeform modules [15]. Object interaction and projection-based AR was used to design and robotically transform a seemingly random material system out of melting wax [16].…”

In this paper, we present a set of enabling technologies developed for the KUKA Innovation Award to facilitate Human Robot collaboration targeted for the architecture, engineering and construction (AEC) sector. Critically, little progress has been made in the usability of user interfaces for industrial robots [1]. We targeted our investigation explicitly towards human-robot collaboration (HRC) in wood based prefabrication production. Although wood is a sustainable material with abundant processing possibilities, it is also a material system where process knowledge remains critically important, making highly automated workflows unfeasible and inefficient. We propose an interactive fabrication process where a user such as a construction worker could wear an augmented reality head mounted display (ARHMD) as an interface to plan robotic trajectories, influence production sequencing, and view superimposed diagnostic feedback. We describe necessary system components including a robotic workcell consisting of a KUKA LBR iiwa, flexFELLOW mobile platform, a Robotiq 2-finger gripper and a custom platform and material feeding station. In addition, we describe a communication framework and set of protocols connecting a CAD digital design environment, a user interface (UI) for Microsoft HoloLens, a ROS server for backend path planning and coordination, and a 3D graphical web interface for downstream visualization of construction status. We conclude with an outlook on enabling technologies for human-robot collaboration in construction, and the importance of increasing digital integration and accessibility in characteristic production workflows through accessible and intuitive digital interfaces.
