Combined Application of 4D BIM Schedule and an Immersive Virtual Reality on a Modular Project: UNLV Solar Decathlon Case

The use of a 4D schedule as technological advancement has brought significant improvement to the planning and execution of construction projects, through visualizing step-wise construction progress, following a sequence of pre-planned activities, and finalizing a baseline schedule with necessary changes. Moreover, the application of immersive virtual reality (IVR) to create an interactive 4D BIM schedule of a planned structure has made it possible to create a detailed plan of any construction project. Because of these benefits, the use of 4D schedules and immersive virtual reality in the construction industry has increased, leading to improved planning and execution. However, past studies have given little attention to the applications of such technologies on modular projects. Thus, this research applied a 4D schedule, along with immersive virtual reality, on a modular project, and verified their benefits and effectiveness. The results showed that most of the participants who experienced a 4D BIM schedule, along with immersive virtual reality (4D/IVR), strongly agreed that it is an easy and straightforward way to visualize the project, understand the schedule, and find any errors. Moreover, while fewer than half of the participants scheduled the assembly sequence correctly with conventional schedule and 2D drawings, almost all of them sequenced the assembly successfully with 4D/IVR. Based on the findings, this research concludes that the implementation of a 4D BIM schedule, along with virtual reality technology, can enhance the fabrication and assembly performance of modules.

The Impact

Construction 4.0 (a concept of Industry 4.0) is an ongoing transformation that aims at digitalization and automation of traditional construction and industrial practices using modern smart technology. The technological development especially of the construction sector is of utmost importance to meet the requirements of rapid construction projects aiming at quality work, increased productivity, and cost savings. One such technology that has come to the limelight is Virtual Reality (VR), which is a computer-generated smart environment that is artificially created using various types of hardware and software. This smart environment is created to resemble a real-life structure that can be explored, visualized, and interacted with by users using electronic devices for better decisionmaking before actual construction. The purpose of this paper is to design a Virtual Reality model using Building Information Modelling (BIM) and to examine the impact and influence of Virtual Reality Technology in the Indian construction industry with the help of a questionnaire survey. This study provides necessary information for implementing Virtual Reality technology in the construction industry. The results of this study provide a research road map to researchers for their future efforts.

Construction Works

Construction Industry is evolving amid the fourth industrial revolution. Transportation, commerce, manufacturing and many other industries ripened the current technological advancement and are striving to utilise every development in the IT sector. The procurement of construction works is known to be very conventional and backward in the adoption of digitalisation. The construction industry's procurement and supply chain are blamed for the most inflated cost of construction projects, mainly attributed to a lack of transparency and trust between the industry stakeholders. This research explores the challenges of E-procurement adoption in the industry and identifies the potential opportunities for its usage. This investigation's data are acquired through interviews, and the data are analysed using qualitative content analysis. This study reveals compounding challenges (i.e., corruption and lack of commitment) that lead to the failure of such efforts in Nigeria and the potential prospects (i.e., transparency and efficiency). This study is essential in developing a more effective and transparent process of procurement so that the Nigerian construction industry is not be left behind in the fast-digitalising markets.

The Real

In recent years, immersive virtual reality technology (IVR) has seen a substantial improvement in its quality, affordability, and ability to simulate the real world. Virtual reality in psychology can be used for three basic purposes: immersion, simulation, and a combination of both. While the psychological implementations of IVR have been predominately used with adults, this review seeks to update our knowledge about the uses and effectiveness of IVR with children. Specifically, its use as a tool for pain distraction, neuropsychological assessment, and skills training. Results showed that IVR is a useful tool when it is used either for immersive or simulative purposes (e.g., pain distraction, neuropsychological assessment), but when its use requires both simulation (of the real world) and immersion (e.g., a vivid environment), it is trickier to implement effectively.
