# Designing a Large-Scale Immersive Visit in Architecture, Engineering, and Construction
### Applications in Architecture, Engineering, and Construction  
Extended reality is a significant modality for the Architecture, Engineering, and Construction (AEC) sectors, because the constructed world is inextricably linked to three-dimensional space and because AEC professionals depend significantly on imagery for communication.  
Six broad use cases have been identified:  
* Stakeholder engagement: Extended reality may be used to engage potential clients or the general public in order to create a more realistic version of a developed asset and to generate more relevant or informed feedback. It may also be quite beneficial in the real estate industry. The system will give professionals and their clients a complete picture of the project, reducing the risk of errors and unpleasant surprises. It will let potential clients inspect homes without physically being present.
* Design support: With the help of extended reality, designers may be able to see how their decisions will affect the final products and learn more about them.

* Design review: VR assist in the transmission of design intent, allowing for more efficient design review; problems can be spotted more easily, and sign-off can be completed more rapidly.
* Construction support: There are four areas where extended reality may be used to help with construction. The first is construction planning. In this field, the major goals of AR and VR are to predict future difficulties and enhance delivery. Virtual Reality (VR) focuses on generating immersive construction simulations, whereas Augmented Reality (AR) focuses on seeing virtual objects that can be built on-site. Tracking construction progress: This is vital because the early detection of schedule delays is essential for on-time delivery. In construction safety, VR can help to create safer working environments by assisting with danger detection and inspection. In the construction industry, when virtual reality is used for training, it reduces the risks that workers face and improves operations. The last area of involvement is operational assistance: VR provides tools on construction equipment teleoperation.
* Building operations and management: As AR may offer important information to site employees who run and maintain buildings, VR might allow for remote operation of the facility in an immersive environment. Both technologies may be used together to help field and remote office employees and increase cooperation.
* Training: Virtual reality may create realistic situations in which users gain knowledge and skills by simulating real-world actions. By mimicking the usage of expensive equipment, modeling risky locations, decreasing travel expenses, and increasing health and safety, both AR and VR technologies may minimize the cost of training.  
Extended reality technologies, however, are not yet stable and dependable enough to meet real industrial requirements. One of the main factors limiting acceptance in the dynamic and severe environment of the construction industry is technical restrictions. One of them is when consumers have negative reactions to VR surroundings as a result of a misalignment between what they see and what they perceive. Another problem is cost. In fact, despite the fact that the cost of establishing VR systems has fallen, considerable financial investments are still required.
