SIP Dataset: Sites in Pieces as Disaggregated Construction Phase 3D Scans

The SIP Dataset (Sites in Pieces) is a collection of single-scan 3D LiDAR point clouds captured in active construction environments using a FARO terrestrial laser scanner. Each scene includes the raw scan and detailed per-object annotations, enabling research on semantic segmentation and providing a foundation for broader analysis of construction scene understanding. The dataset provides construction-phase scans with XYZRGB, intensity, and normal information. Object categories include structural elements, temporary construction objects, and mechanical components, supporting fine-grained analysis of jobsite environments. Code, and detailed dataset structure are available on GitHub: https://github.com/syoi92/SIP_dataset/ Version notes:Zenodo-v3: License updated to CC BY-NC 4.0 to reflect institutional considerations.Zenodo-v4: Updated to SIP-Indoor-v1.3 with Z-axis offset correction.
