Another topic we started to closely is the use of virtual reality and augmented reality in construction, VR and AR. The primary difference between augmented reality and virtual reality is that AR Adds virtual elements to an existing environment. In other words, a screen will add more components to the environment then that are actually there. You can see that actually in the game Pokemon GO. Also AR Open-ended reality requires that that user has a virtual, a scan of the site to then input the built aspects into it. But on another hand, virtual reality, VR immerses the user in an entirely different environment. By shutting the user out of the physical world. By means of VR, users can get transported into a totally new environment, such as a construction site or a new building. Now, there are many benefits of using both augmented reality and virtual reality in our industry, such as saving on costs. This can happen by providing access to the site without having to travel. Also Increase the productivity and enhance coordination between a project teams. For example, it helps owners to envision the outcome of the project during the design phase. And facilitates better and individuals. Communication between owners designers and contractors, so that all parties can have access to the same model without being in the same place at once. Now if you think about it, it will also help in the area of conflict and distribution. Augmented reality and virtual reality provides a universal visual language, that is also capable of being understood by professionals in different fields. That technology enables the design phase to be as coherent as possible. And thus enable the design in general to be as close to the desired idea as we can. By doing so, customer expectations are met, or sometimes even exceeded, which will then lead in reducing any potential conflict between all different partiesiIn the project. One pricing topic that is worth also mentioning here, especially with the use of virtual reality VR is the rise of virtual training. An area I'm personally heavily interested in. Examples can be on how to use certain construction equipment. You enter into a simulated environment to train you and the workers and the engineers on how to use specific construction equipments. Before you actually get into inside the equipment. I tried it myself It was really outstanding. Also training workers and engineers and staff on some exercises that are related to increase safety practices before you join the project. In general, there are many startups in this area that worth mentioning. Such as open space, our Struction site, and I believe also portal vendors. Another rising area that currently is getting more and more attention is digital twins. It's definitely an area worth mentioning here. My team did deeper into this area from conducting comprehensive literature review about what's happening with digital twin in construction. So what is digital twin? Digital twin is a digital representation of a physical asset. But when, when it got supported by the Internet of things, IOT, and artificial intelligence AI as well as ML machine learning, in addition, it went can then automatically get updated. According to adjustments made in the real world. Or at the actual physical twin. So this digital twins are up to date copies of the physical twin, that delivered information on the project, properties and status. Of course the type of information collected and it transferred between the physical twin and digital twin can vary and include physical orientation. Such as shape, position or even motion as well as inside Into other status, interactions and updates about the physical object or that physical twin. So to add to this digital twins, align the reward with the virtual world. And help either we need the impact that the environment has on a given physical assets. So when several integrated technologies such as that Internet of Things IOT, artificial intelligence, AI, and machine learning, all come together. Additionally twin is able then to learn from these multiple sources and information input by gathering real feed back of data and information. And automatically adjust to accurately represent the status, condition and position and position of its real world counterpart. Now, a dish that a twin in our industry can be used in many ways, such as visualization, documentation, modeling, analysis and planning. Let me highlight examples of a more specific applications. One. Additionally, twin can assist a facility manager to know how a building is performing in real time, which enables them later to optimize efficiency of the building. Also, such data can be used for planning and designing of future building. Digital twins can also help to predict potential failures in systems like HVAC, water and electrical. This can save on time and expensive shutdowns of these services and systems. Also, last but not least, a digital twin, Provide a project team with access to [INAUDIBLE] Designed models which are constantly synced in real time. Now this allows the team to continuously monitor progress against the 4D building information modeling model or the BIM model.
