VR Empowers Smart Construction: Digital–Physical Integration Boosts Quality and Efficiency in Building Projects

To advance the digital and precision‑driven transformation of construction operations and address longstanding challenges in traditional MEP installation, the Jinrun Branch of the Group has successfully implemented VR‑based virtual construction technology on the Jotun Coatings (Zhangjiagang) Co., Ltd. relocation and expansion R&D center project. By leveraging a mixed‑reality, visualized workflow, this approach enables precise control over construction details and optimized project planning, providing robust technical support for high‑quality project delivery.

For a long time, building MEP installation projects have faced industry‑wide challenges, including complex pipeline layouts, extensive interdisciplinary coordination, and difficulties in verifying concealed works. Traditional construction relies on 2D CAD drawings for design and review, heavily depending on the individual expertise of engineers and struggling to comprehensively anticipate issues such as pipe clashes, improper elevation discrepancies, and spatial conflicts. Design errors in most concealed pipelines are often detected only during later stages—such as ceiling construction or pipeline installation—resulting in schedule delays, material waste, cost overruns, and compromised overall construction quality. These shortcomings represent a critical bottleneck that hinders efforts to improve both the quality and efficiency of building projects.

To address the aforementioned challenges, this project has actively integrated VR virtual reality technology, breaking through the visual limitations of 2D drawings and establishing a visualization‑based construction verification system that combines real‑world scenes with 3D models. During construction, technical personnel use VR augmented reality to precisely project a mature BIM‑based 3D building model into the physical construction workspace, overlaying virtual 3D representations of various concealed pipelines—such as ventilation, plumbing, electrical and low‑voltage cable trays, and fire‑protection systems—onto the actual building structure in distinct colors. Specifically, green, purple, yellow, and red models correspond to ventilation, plumbing, cable trays, and fire‑protection pipelines, respectively. Key parameters—including installation locations, routing, elevations, and spacing—are presented clearly and intuitively, making even hidden works “visible, traceable, and verifiable.”

Leveraging VR‑based virtual‑reality comparison technology, the project has achieved proactive construction management and precise verification. Project managers can conduct immersive reviews of critical construction elements—such as pipeline layouts, support‑structure installation, and clearances—identifying potential interferences and conflicts among ductwork, piping, and electrical cable trays well in advance. This enables optimization of design solutions prior to formal construction, thereby preventing rework and rectification at the source and ensuring rigorous control over construction accuracy and overall project quality.

“The application of VR technology not only enhances the precision of single-discipline construction but also breaks down communication barriers in multidisciplinary collaborative projects,” explained Zhu Xianglei, the project’s on-site technical lead. Electrical, piping, HVAC, fire protection, and other construction teams can now leverage a unified mixed-reality environment to conduct site meetings, align design solutions, and carry out detailed technical briefings, thereby standardizing construction practices, clarifying scope boundaries, significantly reducing cross-disciplinary communication errors, effectively minimizing construction changes, and delivering tangible cost reductions and efficiency gains.
