At the end of the 8-month problem detection and research-development process, it was decided to use new generation technologies to solve the identified problems. It has been understood that the most accurate way to measure user benefit is to examine projects from the user’s point of view. It was decided to carry out a full-scale examination in 3D areas instead of checking from 2D screens. In this context, studies on the use and integration of virtual reality technologies within the institution have started. At this point, Turkey’s largest transportation network operator company preferred CorpLine CorpSide solutions.

It was decided to develop integrated virtual reality applications using C# software language and graphics engines. The systems are planned to work in integration with Autodesk Revit, the world’s most advanced software used for BIM solutions. The developments of all project units were gathered on Revit and it was decided to make instant control effortlessly with both structural progress and virtual reality solutions working in integration with this field.

The systems to be developed should be easily used by all teams (structural, architectural, mechanical, field). Integrated software must have suitable working conditions for large files. An average metro project station is x5 times the size of an average residential construction project. The ability to handle and display this heavy load needs to be improved. Material costs should be reduced by reducing equipment and resource needs. Devices with lower features and capacities should be able to be used. Everything must be mobilised. It should be accessible to all teams working in different buildings and campuses of the institution. It should be used in executive presentations and evaluation meetings. It should be open to different scenarios and simulations. Multiple station integration must be possible. It should be available to the public for testing and presentation processes.

At the end of all analysis and research-development processes, more than one virtual reality software was created. Various simulations have been tested. A decision was made on the option that most appealed to the needs of the institution. Project evaluations were made from the user’s point of view by using the system in architectural evaluation meetings. Up to 15% structural change was achieved within the station. Thus, the harmony between the intended materials and the station to be built has been achieved. Unnecessary construction and demolition-rebuild costs are avoided. The projects developed by the teams were integrated instantly and their working together was controlled, thus accelerating the project development process. Station presentations were made to the senior management of the institution during the project design phase, and the opportunity for high level control and appreciation was gained. The comments and feedbacks of the public on the stations were collected by making presentations at international fairs and organizations.
