## 4 Case Study
### Integration of Case Study
#### 4.2.1 Implementation Process in Xiong'an New Area  
In the context of Xiong'an's projects, the application of this methodology encompasses several pivotal facets. From the micro to meso dimension, the standardization of model file formats is of utmost significance. Given the extensive range of fields implicated in Xiong'an's planning and construction endeavors, a multiplicity of BIM software is deployed. Through the utilization of format conversion plug-ins, diverse format models (such as the RVT format from Autodesk Revit in the architectural realm and the DGN format from MicroStation in municipal engineering) are transmuted into the XDB format, thereby streamlining the unified management of individual project models. For illustrative purposes, a municipal road and its adjacent building project can be integrated and analyzed on a single platform subsequent to format conversion.  
The unification of data standards is equally indispensable. Xiong'an has promulgated BIM data coding guidelines and associated standards, spanning multiple domains. In the main venue project, the component coding within the building structure model is meticulously defined. This empowers the construction unit to accurately extract control data, including room area, building height, and wall characteristics, thus laying a robust foundation for project management.  
With respect to contract constraints, the local management committee has been proactive in bolstering BIM application. During the bidding phase, pertinent regulations accentuate the significance of BIM, inducing bidders to embed it within contract provisions. Contracts meticulously delineate the scope and responsibilities of BIM application, ensuring the adherence of all parties and fostering collaborative efforts. For instance, contractors are mandated to simulate construction progress using BIM and submit periodic reports.  
From the meso to macro perspective, model analysis is actualized via the SuperMap platform. By amalgamating BIM and GIS models, Xiong'an undertakes in-depth analysis of XDB files, extracting semantic and geometric information and effectuating coordinate transformations to engender UDB models. This integration facilitates government departments in discerning the spatial relationships between buildings and the surrounding environment, thereby enhancing urban planning precision. In a particular area's planning process, potential conflicts between building designs and underground pipe galleries were detected and rectified through model analysis.

Data integration harnesses the UDB engine to coalesce spatial and attribute data. On the SuperMap platform, the fusion of BIM-GIS data enables the extraction and computation of macro control data, such as plot ratio and building density. In the planning of a residential community, the initially excessive building density was optimized through data integration analysis.  
Institutional safeguards are furnished by a suite of regulations in Xiong'an. These regulations unambiguously demarcate the BIM responsibilities of each unit, ensuring its efficacious implementation throughout all project phases and enabling seamless collaborative management between the committee and construction entities. For example, planner units are required to employ BIM for the generation of accurate planning models and the conduct of multi-plan comparisons.
