GNI BIM Dataset

224 anonymized IFC building models from student coursework at the TUM Georg Nemetschek Institute – AI for the Built World / Chair of Computing in Civil and Building Engineering, Technical University of Munich, released with the authors' consent under CC BY 4.0. 2025_BIMfundamentals/ — 208 single-discipline models from the BIM Fundamentals master course (Summerterm 2025). Each model was created individually by a student in a commercial BIM tool. 2026_BIMprojects/ — 16 models from 9 teams in the BIM Project master course (Winterterm 2025/26). 7 of 9 teams produced paired architectural + structural models of the same building. Identifying information (author names, organizations, addresses, project metadata) was removed from all IFC files. Anonymization scripts are available at https://github.com/ZijianWang-ZW/GNI-BIM-Dataset. Across 223 parsed models, the dataset contains 290,877 element instances spanning 42 IfcElement subclasses (walls, slabs, beams, columns, doors, windows, structural framing, MEP, furnishings, and more). Models use IFC2x3 and IFC4 schemas. A CSV file with links to 35 other online IFC model collections is included.本数据集包含224个经过匿名化处理的工业基础类（Industry Foundation Classes，IFC）建筑模型，源自慕尼黑工业大学（Technical University of Munich, TUM）格奥尔格·内梅切克研究所——建筑领域人工智能方向/土木与建筑工程计算教研室的学生课程作业，经作者同意后以知识共享署名4.0（CC BY 4.0）许可协议发布。 2025_BIMfundamentals/ — 包含2025年夏季学期《BIM基础》硕士课程中的208个单专业建筑信息模型（Building Information Modeling，BIM）模型，所有模型均由学生使用商用BIM软件独立创建。 2026_BIMprojects/ — 包含2025/26年冬季学期《BIM项目》硕士课程中9个团队的16个模型，其中7个团队分别完成了同一建筑的成对建筑专业与结构专业模型。 所有IFC文件均已移除标识信息（包括作者姓名、所属机构、地址及项目元数据），匿名化脚本可通过https://github.com/ZijianWang-ZW/GNI-BIM-Dataset获取。 在已解析的223个模型中，本数据集共包含290,877个构件实例，涵盖42个IFC元素（IfcElement）子类，包括墙体、楼板、梁、柱、门、窗、结构构架、机电工程（Mechanical, Electrical, Plumbing，MEP）、陈设家具等。所有模型采用IFC2x3与IFC4标准数据架构。 本数据集附带一个逗号分隔值（Comma-Separated Values，CSV）文件，其中包含指向35个其他在线IFC模型数据集的链接。
