However, point clouds acquired from real construction sites commonly suffer from high labeling costs, severe occlusion, and unstable data distributions. Existing public datasets remain insufficient in terms of scale, component coverage, and annotation consistency, limiting their suitability for data-driven approaches. To address these challenges, this paper constructs and releases a BIM-derived synthetic construction scene point cloud dataset, termed the Synthetic Point Cloud (SPC), targeting component-level point cloud semantic segmentation and related research tasks.The dataset is generated from publicly available BIM models through physics-based virtual LiDAR scanning, producing multi-view and multi-density three-dimensional point clouds while automatically inheriting component-level semantic labels from BIM without any manual intervention. The SPC dataset comprises 132 virtual scanning scenes, with an overall scale of approximately 8.75\u00d7109 points, covering typical construction components such as walls, columns, beams, and slabs. By systematically configuring scanning viewpoints, sampling densities, and occlusion conditions, the dataset introduces rich geometric and spatial distribution diversity. This paper presents a comprehensive description of the SPC data generation pipeline, semantic mapping strategy, virtual scanning configurations, and data organization scheme, followed by statistical analysis and technical validation in terms of point cloud scale evolution, spatial coverage characteristics, and component-wise semantic distributions. Furthermore, baseline experiments on component-level point cloud semantic segmentation are provided. The results demonstrate that models trained solely on the SPC dataset can achieve stable and engineering-meaningful component-level predictions on real construction point clouds, validating the dataset\u2019s usability in virtual-to-real research scenarios. As a scalable and reproducible BIM-derived point cloud resource, the SPC dataset offers a unified data foundation and experimental support for research on construction scene point cloud semantic segmentation, virtual-to-real transfer learning, scan-to-BIM updating, and intelligent construction monitoring.<\/jats:p>","DOI":"10.3390\/data11010016","type":"journal-article","created":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T08:17:32Z","timestamp":1768292252000},"page":"16","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A BIM-Derived Synthetic Point Cloud (SPC) Dataset for Construction Scene Component Segmentation"],"prefix":"10.3390","volume":"11","author":[{"given":"Yiquan","family":"Zou","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Architecture and Environment, Hubei University of Technology, 28 Nanli Road, Wuhan 430068, China"}]},{"given":"Tianxiang","family":"Liang","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Architecture and Environment, Hubei University of Technology, 28 Nanli Road, Wuhan 430068, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6906-9370","authenticated-orcid":false,"given":"Wenxuan","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Architecture and Environment, Hubei University of Technology, 28 Nanli Road, Wuhan 430068, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5876-9568","authenticated-orcid":false,"given":"Zhixiang","family":"Ren","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Architecture and Environment, Hubei University of Technology, 28 Nanli Road, Wuhan 430068, China"}]},{"given":"Yuhan","family":"Wen","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Architecture and Environment, Hubei University of Technology, 28 Nanli Road, Wuhan 430068, China"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"100319","DOI":"10.1016\/j.chbr.2023.100319","article-title":"Towards Human-Centered Artificial Intelligence (AI) in Architecture, Engineering, and Construction (AEC) Industry","volume":"11","author":"Nabizadeh","year":"2023","journal-title":"Comput.
