“…While the matrix is developed based on the PSP experts and is specific to the integration of AR with PSP, some of the interactions can be observed in previous research work where authors developed applications to illustrate the use of AR in the construction industry. For instance, the research of (Chalhoub and Ayer 2017) demonstrated that the ability of AR to remove intermediary steps to look through 2D drawings and manuals to find needed data enables better communication between project professionals and more efficiency to assemble prefabricated electrical conduit.…”

The Production Strategy Process (PSP) is an integral part of production planning and control as it defines how production processes are structured and designed and outlines how production will be executed. PSP involves massive information transfer and communication among project participants. While BIM can improve the flow of information, the paradox of designing 3D models in 2D space remains. This paradox indicates that new visualization technologies are needed to leverage the use of information in the PSP. As Industry 4.0, the fourth industrial revolution, continues to evolve, it is imperative that construction firms seek, find, and adopt new technologies. This research employed Augmented Reality (AR) as a new user interface in the PSP. The current state of practice of PSP was investigated and current challenges are identified. The opportunities to integrate AR were defined, and an AR-enabled future state was proposed. Next, an AR-enabled PSP prototype using the Microsoft HoloLens was implemented and validated on a real-world healthcare project. Usability testing was then conducted using a one-on-one protocol to validate the prototype with 20 participants. Surveys were the deployed to qualitatively assess the impact of integrating AR into PSP. The difference between the traditional PSP and the AR-enabled PSP was tested through a series of hypotheses comparing both processes. The results demonstrate that the AR-enabled PSP offers significant benefits over the Traditional PSP: improved collaboration, reduced miscommunication, increased quality and detection of errors, enhanced decision-making, better documentation, better information access, improved information flow, increased input accuracy, and increased integration of safety considerations. Additionally, the technology, software, and hardware were also evaluated, and, on average, the findings demonstrated the potential of AR in production planning.

“…The researchers have previously compared the performance of experienced practitioners completing a conduit assembly task (Chalhoub and Ayer, 2017) and an electrical point layout task Ayer, 2019a, 2019b) using AR and using traditional construction plans. While this current paper explores the same tasks, it uses a different sample set of participants without the experience levels possessed by participants in prior papers.…”

The construction industry is facing a severe labor shortage that is threatening the performance of projects around the world. Advanced technologies may be able to alleviate the effects of this labor cliff. Specifically, Augmented Reality (AR) has been shown to enhance the performance of current industry professionals completing different construction tasks and is also being explored as a learning tool for students and technicians alike. This research studies if AR can be used as a tool to enable untrained individuals to complete construction tasks. Three groups were identified for this research: construction professionals, construction students, and individuals with no construction experience. All three groups completed two construction tasks with AR, including the assembly of prefabricated electrical conduit and the layout of electrical devices in a room. The results show that all three groups completed the task in statistically similar times; however, the work of individuals with no construction experience had significantly lower accuracy during the electrical device layout task. These results suggest that construction companies may be able to leverage untrained individuals to perform certain construction tasks with AR, enabling trained and experienced professionals to focus on more challenging tasks.

“…Chryssolouris et al [9] evaluated the use of AR assembly instructions in manufacturing and found that they contributed to reduced product development times and cost savings while simultaneously improving first-time quality and market response time. An experiment conducted by Chalhoub et al [10] showed that MR can be effective for communicating design for electrical prefabrication.…”

The construction industry often falls short of other industries in terms of innovation; overall productivity within the construction industry has remained nearly flat for fifty years. As such, the industry is frequently exploring new technologies with the potential to increase its work efficiency as well as productivity. Mixed Reality (MR), which allows for the blending of real and virtual worlds, is one such technology that has a capability to improve productivity. The aim of this research study is to test MR's potential as an onsite assembly tool in construction. The study more specifically determined if holographic BIM models, spatially anchored in 1:1 ratio over active construction sites, could provide trades' sufficient information to assemble and install their work without using paper plans. A controlled experiment was designed to test if the electrical and plumbing components of a mock-bathroom could be installed only with MR. A total of 5 sub-groups, each consisting of two participants, took part in this experiment and the time is taken by each sub-group (i.e. the MR group) to complete the assembly was recorded. This was then compared with the time taken by a similar number of sub-groups (i.e. the Control group) to complete the same assembly using paper plans only. The analysis indicates that on average the MR group took approximately 9% less time as compared to the Control group. Qualitative analysis via a post-exercise questionnaire found several technological limitations that the MR must overcome before it sees widespread implementation as a tool for guiding construction assembly. The post-exercise questionnaire also gathered participants' perceptions about MR potential in construction. This paper highlights the benefits and limitations of the MR technology in construction along with recommendations for improvement as well as future research.
