Building Information Modeling, commonly known as BIM, was first introduced as a term in 2002 to describe building information technology. It was coined by Philip Bernstein, then Vice President of Autodesk in the United States. Bernstein viewed BIM as a groundbreaking innovation in building design and construction processes, aimed at creating and utilizing coordinated, internally consistent, and computable information throughout project design and construction phases.
The Wutong Tree Building in Hengqin, Zhuhai, began construction in 2015. The project covers a total area of 172,528.89 square meters with a height of 188.8 meters. Its structural system combines a frame shear wall with an open web cantilever scaffold. The seismic fortification intensity is rated at 7 degrees, and the basement holds a Grade I fire resistance rating.
China Construction Third Engineering Bureau utilized Luban BIM for distributed modeling of various underground specialties, identifying issues in the drawings and compiling them into comprehensive review documents. BIM visualization was used to precisely locate reserved voids within the concrete and perform clash detection on pipelines from multiple mechanical and electrical disciplines, enabling timely coordination and collaborative modifications among all parties.
Engineering quantity data was submitted in real time based on construction progress, allowing comparison of actual material usage against model-based standard quantities. This facilitated effective tracking and cost control of materials. During construction, BIM-enabled mobile devices collected on-site data, detected design drawing errors, and compared them in real-time against BIM cloud models to monitor project progress, quality, and manage design changes.
Through BIM application in both design and construction phases, 55 issues and 5 structural design problems were identified in the basement drawings. Additionally, BIM’s multi-disciplinary integrated net height inspection revealed 49 net height deficiencies, greatly reducing rework and enhancing project quality. Twelve change records were promptly coordinated and updated.
Project data was stored and managed in the cloud, supporting future operation and maintenance efforts. Furthermore, this project serves as an exemplary case for BIM application training.
