However, quantifying BMS in urban areas with scarce material data remains challenging. This paper addresses this challenge by proposing a “parametric archetype” method, which integrates similarity measures in BMS modelling. The similarity in material content between buildings is quantified using an Euclidean distance measure based on multidimensional building feature parameters. By mapping material data to similar buildings, a cohesive dataset can be formed and further enriched, enabling incremental larger-scale BMS aggregation. This model is trained using a dataset with 52 Singapore buildings, achieving a 20.24% error rate in material predictions for all urban buildings. The finding highlights the feasibility of conducting BMS aggregation with quantifiable accuracy even with limited material data points.

Three-dimensional (3D) point clouds from LiDAR or photogrammetry can facilitate these inspections, but are difficult to leverage without automatically identifying individual structural elements. Existing research focuses on semantic segmentation, which classifies points into broader categories rather than identifying each element instance. A major bottleneck is the difficulty of producing instance-level annotations. To address this gap, the paper proposes and evaluates three synthetic data generation approaches to produce automatically labeled point clouds of bridges with element instance-level annotations. An occlusion technique is introduced to increase realism. The synthetic data is then evaluated for training Mask3D transformer model for instance segmentation of field-collected point clouds, achieving mean Average Precision (mAP) scores of 91.7 % on LiDAR data and 63.8 % on photogrammetry.
