“…In contrast to our previous work devoted to refining building models with underpasses (Wysocki et al, 2022a), in this paper we focus on detecting and reconstructing outstanding fac ¸ade openings, such as windows and doors. Moreover, our method refines point cloud segmentation by back-projecting classified conflicts onto the input point clouds.…”

“…These are back-projected to the point cloud, refining its segmentation accuracy. If the Bayesian network detects windows or doors, shape extraction is conducted (Section 3.7); otherwise, another module can be triggered, such as the underpass reconstruction (Wysocki et al, 2022a). Opening shape extraction is followed by shape generalization, which delineates fitting borders for 3D reconstruction (Section 3.7).…”

“…In the absence of beams, the net height requirement of the bridge under the bridge can be minimized so that it will reduce the volume of excavation. The bridge plate is then designed to be integrated with the pillars of the retaining sheet pile so that in this position the sheet pile will receive the load from the side soil pressure and will also receive and transmit the load from the bridge slab plate (Brehme et al, 2021;Jiang et al, 2022;Wysocki et al, 2022). Calculation of internal forces until the reinforcement design is obtained for both the sheet pile construction and the superstructure and substructure of the bridge will be carried out using SAP 2000 v.14 software.…”
