Submission for buildingSMART International «openBIM Award 2023»
Located in Shenzhen city, the Shenzhen Qianhai Xinhua Life Building Project consists of a super high-rise office tower house and a three-story commercial podium. The building is mainly used for office, business, catering, community services, and underground parking.
As a designed general contracting mode, the project adopts forward BIM design and delivers all professional design documents at the same time. The BIM model is built in strict accordance with the standard and selected as a pilot project of Shenzhen BIM digital standards. Architectural and structural models are edited in cooperation with building code checking.
Therefore, BIM research team of Tsinghua University Software School proposed the solution to develop a standard compilation tool(Knowledge Base) and a BIM viewing and checking tool (CBIMS Manager), and at the same time, combining the standards with local needs.
The model records a large amount of 3D semantic information of design results. In order to deal with problems such as model isolated data island, model quality control, model approval, and model-based collaboration in BIM application, this project has practiced model merging, exporting, model quality checking, building code checking, collaboration and optimization, lightweight display by investigation, analysis, refinement on international & national standards in the design phase.
On Knowledge Base, view SJG Standard for Building Information Modeling Semantic Dictionary, and add object identifiers as required.
On Knowledge Base, view SJG Standard for Engineering MVD for code checking of Building Information Modeling (Building Construction Project Planning Approval Fascicule), and add object identifiers, download digital rules accordingly.
On Knowledge Base, view Building Construction Project Planning Approval and related SNLs, download digital rules.
Revit end conversion plug-in ensures complete model export. It exports the material texture and optimizes the file size to make the IFC model smaller, prettier, and better.
The model quality requirements for subsequent application scenarios (e.g. building code checking) are converted into MVD rules. Run model quality checking to the example IFC model and the inspection results are detailed.
SNL rules can be formed by digitizing related building codes. After running the building code checker to the example IFC model, the detailed checking results are listed.
Covert results from Model Quality Checking and Building Code Checking to bcf files，open with design softwares for collaboration and optimization.
