“…That is, missing information regarding the accuracy of the estimated location for a particular tag at a specific time. Incorrect object locations might lead to false confidence that is typically counterproductive and sometimes dangerous [47]. For instance, a field crew might be struck by a truck because of the incorrect information regarding the location of the truck and the crew and consequently, the distance between them.…”

“…The current status of utility data is in need of some improvements. Previous researchers highlighted the lack of digital formats [2] and inaccuracy of as-built information [3]. The need for a shared geospatial platform is suggested to be key to handheld AR applications [4], especially with reference to mobile market hardware developments [5].…”

“…Other countries such as Singapore have begun to make their infrastructure data more accessible, where various benefits to procurement of such projects are being realized [9] with some direct benefits for quality assurance as well as facilitating visualization methods. Although with increased use of GPS technologies, data collection and storage are beginning to merge [3], interoperability and encapsulation of non-asset data remains a challenge and may affect excavation and space planning practices [10].…”

The process and product development phase of the research instrument for experiential action research is crucial in the success of the research. Due to time, space and resource limitations, fewer studies have concentrated on this development process. In this respect, research on Augmented Reality (AR) in the architecture, engineering and construction (AEC) industry is no exception. This is more evident in subsurface, urban utilities and infrastructure sector. Furthermore, a limited number of studies on AR/VR have utilized mobile devices as their enabling technologies. This paper sets out to contribute to the state-of-the-art in AR research for urban utilities and infrastructure by outlining a generic procedural workflow to be used for designing AR experiments for experiential research in this area. Given the fact that workflow development research in AR is still limited, this research presents a unique contribution in this area to date.

“…The next most common focus was general safety (34.8%), followed by falls (28.3%), and lastly, electrical hazards (13%). Talmaki et al [52] focused on the hazard of striking underground utilities and Lu and Davis [53] discussed the effects of noise on risk perception-the two publications are listed as "other" (4.3%). The categories of struck-by and caught-in are similar hazard types in that they are often caused by corresponding construction activities, especially the operation of heavy equipment such as cranes.…”

Over the last decade, researchers have used virtual-and mixed-reality (VR-MR) techniques for various safety-related applications such as training, hazard monitoring, and preconstruction planning. This paper reviews the recent trends in virtual-and mixed-reality applications in construction safety, explicitly focusing on virtual-reality and mixed-reality techniques as the two major types of computer-generated simulated experiences. Following a systematic literature assessment methodology, this study summarizes the results of articles that have been published over the last decade and illustrates the research trends of virtual-and mixed-reality applications in construction safety while focusing on the technological components of individual studies.Safety 2019, 5, 51 2 of 16 high refresh rates, accurate point-of-view tracking; these benefits are possible at lower costs than in the past, mainly because VR-MR systems are gaining traction in the mainstream gaming community [9]. Investment in VR-MR technology is increasing, and the VR-MR market is projected to increase from $2.67 billion in 2015 to $66.68 billion by 2022 [10].This study analyses the current trends in virtual-and mixed-reality applications in construction safety, particularly focusing on virtual-reality and mixed-reality platforms as the two major types of computer-generated simulated experiences. This study also focuses on the technological components of those VR-MR studies and discusses individual examples of research projects that implemented such technologies for construction safety application. A few scholars have published review articles of digital visualization techniques for safety applications. Zhou et al. [11] conducted a review of advanced technology for safety. Bhoir and Esmaeili [12] explored VR environments for safety; Guo et al. [13] looked at visualization technologies for safety. Li et al. [14] reviewed virtual and augmented reality systems for safety. Unlike other reviews, this study asks specific research questions through a systematic review technique and individually discusses the papers within the context of different safety applications, as well as their technological components. Moreover, by intentionally limiting the scope of the review to VR and MR, this study can highlight interactive safety interventions with detailed summaries of application areas, while separating VR and MR from the larger, general field of BIM (Building Information Modeling), 4D CAD (Computer-Aided Design), and other visualization technologies. The significance of this research lies in that it presents the application status of VR and MR in enhancing safety in the construction domain and brings more attention to these promising technologies and ultimately improves safety in the construction domain. The expected outcome of this content-analysis-based review can benefit both industry professional and researchers who find it necessary to design and develop an efficient application employing VR/MR technologies to enhance safety processes in the construction ...
