(1) Manual Control. Manual control is primarily managed by the project manager and on-site construction personnel. By integrating BIM and VR technologies, managers can enhance work efficiency and gain a deeper understanding of project quality. Unlike traditional CAD technology, BIM offers a significant advancement with 3D modeling capabilities, enabling project managers to anticipate and manage technical aspects in advance. Potential construction issues can be identified early, allowing frontline workers to be trained before actual construction begins, thereby minimizing errors. The efficiency of frontline workers plays a vital role in the success of engineering projects. Incorporating VR within BIM simulates on-site construction procedures, helping workers visualize key construction stages clearly. This reduces quality issues caused by oversight, provides guidance on critical tasks, improves overall project quality, and decreases major mistakes made by construction personnel.
(2) Mechanical Control. BIM+VR technology can simulate the on-site layout of construction teams, enabling a precise division of labor for each group. It helps plan the construction sequence, timing, and the movement of machinery efficiently. For example, it can optimize the placement of the concrete mixing plant and cleaning equipment at site entry and exit points. By coordinating different teams effectively, the entire construction site operates more smoothly and efficiently, ultimately accelerating the overall construction progress.
(3) Material Management Control. Construction materials are typically commercial products that are processed remotely and delivered to the site. Since these materials directly impact the quality of the project, managing incoming supplies is critical. BIM technology, combined with a virtual project model, helps create an accurate on-site material supply plan aligned with construction progress. It determines the types and quantities of materials needed within specific timeframes, ensuring sufficiency and quality throughout usage. The recorded data within the model serves as a reference for future projects, guiding material preservation and usage. BIM+VR also provides real-time tracking of materials used in each project and displays merchant information within the project’s information model, allowing comprehensive analysis of suppliers and materials.
(4) Method Control. BIM+VR technology enables project managers to simulate various construction plans and select the optimal one through comparison. By building a virtual reality scene based on a 3D building model, a simulated environment is created where the model gains dynamic characteristics. Results from VR virtual assembly allow modification of construction plans through human-machine interaction in a visual environment. This method ensures that the construction process follows the most efficient plan. Applying BIM+VR virtual construction concepts to specific processes allows designers, contractors, and owners to understand project details during planning and design phases—before any physical construction—without wasting materials or labor, preventing unnecessary rework.
(5) Environmental Control. Introducing BIM+VR technology places the project model within a virtual reality environment that incorporates meteorological, geographical, and other site-specific characteristics. This enables preliminary simulations of environmental conditions during construction, allowing early analysis and problem solving. Potential challenges caused by unfavorable factors can be visualized as three-dimensional physical structures, helping project managers identify and address issues proactively.
