Since 2011, Wanda Commercial Real Estate has introduced three major innovations in project management: planned module information management, a turnkey general contracting management model, and a new project management approach based on full-process BIM information integration, currently under development. The foundation of this new model is the BIM (Building Information Modeling) technology, which plays a crucial role in providing technical support and integrating technology into management.
So, what exactly is the Wanda BIM model? The Wanda BIM experimental model is a collaborative BIM design project developed by the Wanda BIM R&D team along with numerous partners. It encompasses 12 specialized design disciplines, 48 electromechanical systems, and includes 304,447 component instances spread across 78 model files. The entire model occupies 8.41 GB of storage and features 2,826 columns, 12,356 beams, 67,069 square meters of air ducts, 139,045 meters of piping, 57,203 pipe fittings, 3,679 electromechanical devices, and 268 different materials. If these numbers alone don’t fully convey the depth of the BIM model, read on as Xiaowan reveals the details behind this remarkable technology.
Professional design coordination is carried out using the BIM models for each discipline. In the Wanda experimental project, collision detection was performed across different disciplines, uncovering design conflicts unrelated to individual specialties. These issues were resolved through design coordination meetings involving professional designers. Beyond the usual mechanical and electrical pipeline integrations, collision checks extended to landscaping, small municipal infrastructure, curtain walls, night lighting, interior decoration, and other related fields.
Following a thorough professional review, several design issues caused by the limitations of traditional two-dimensional design were identified and corrected, including:
- The entrance and exit roof protruded beyond the landscape platform. After discussions with designers, this portion of the roof was removed.
- Structural diagonal beams installed beneath cinema seats reduced the clear height in the cinema’s entrance aisle to less than 2400 mm. Structural engineers adjusted the beams to ensure adequate clearance.
- Previously, positioning interfaces between night lighting and curtain walls were often unclear. This time, the curtain wall team reserved dedicated slots for night lighting fixtures in advance, ensuring precise placement.
- Mechanical and electrical terminals frequently conflicted in positioning with interior decoration elements. In this project, these specialties coordinated using the 3D model to prevent equipment and maintenance access conflicts caused by misalignment.
Wanda’s experimental BIM model goes beyond serving as a construction drawing; it also supports cost estimation, planning, and quality supervision. For cost-based calculations, the model demands higher levels of detail and accuracy, surpassing the LOD 300 standard, with some components reaching LOD 400-500. Each discipline expanded the modeling scope and precision to meet cost estimation requirements, including elements like structural post-pouring strips, foundation cushions, equipment bases, fan connection brackets, suspended air conditioning spring hangers, layered landscape pavement structures, retaining wall levels, and specialized planting pools.
Wanda Group has developed an electronic sample material library to standardize material input. Every material in the library is assigned an electronic code and includes detailed information such as material name, color, texture images, applicable areas, process requirements, specifications, surface treatments, and construction techniques. The actual materials used in the Wanda experimental project were matched with data from this library and assigned to the BIM model components. Renderings produced with BIM software closely matched the electronic sample images, ensuring visual and material accuracy.
The ultimate aim of Wanda Group’s application of BIM technology for component classification coding is to enable integrated management of building information throughout the entire project lifecycle. This classification coding acts as a data bridge connecting design, cost estimation, planning, quality supervision, and operations management. By implementing this system, seamless data exchange and application across all stages are achieved. Consequently, all components in this project have been assigned classification codes aligned with assembly construction standards.
As a massive enterprise, Wanda has achieved multiple groundbreaking innovations over the years. Recently, the company has moved beyond traditional hand-drawn blueprints to develop this new project management model. Chairman Wang Jianlin described it as a “revolution in the history of global real estate development and construction.” The call for transformation has already been sounded. In 2016, to meet the growing demand for BIM models across various business lines, Wanda’s BIM experimental models will continue to advance, providing essential technical support for the company’s ongoing transformation and innovation in commercial real estate.
