The construction sector is a rapidly evolving sector where dealing with important technology issues is essential for their survival. These technologies are Virtual Reality and Augmented Reality We have used these two techniques as auxiliary tools for the development of BIM, where the design errors are discovered and processed at an early stage, in addition, we can preview the real-size spaces (sizes, spaces, heights) And provide the comfort and trust with the customer as it enhances the viewer as well as its benefits in marketing. Using the VR technique, the 3D model was transformed from a 3D model within a two-dimensional screen to a real three-dimensional display in virtual reality using VR technology. The use of Augmented Reality technology allows us to integrate the existing model in the computer with the reality we live in, such as to see through the mobile camera the image of the room in addition to imaginary furniture, and Augmented Reality allows the ability to recognize the three-dimensional models through two-dimensional schemes And interact with them.
