Automated reconstruction of parametric BIM for bridge based on terrestrial laser scanning data
Qin, Guocheng; Zhou, Yin; Hu, Kaixin; Han, Daguang; Ying, Chunli (Advances in Civil Engineering;Volume 2021, Journal article; Peer reviewed, 2021-01-08)Building information modeling (BIM) in industrialized bridge construction is usually performed based on initial design information. Differences exist between the model of the structure and its actual geometric dimensions ... -
AUTOMATED REVERSE Modeling and examination of as-built steel truss based on point cloud data: Machine learning and bim
Selvakumaran, Eraikumaran (MABY;2021, Master thesis, 2021)Building Information Modeling (BIM) has improved the way structures are designed and constructed over the last decades. Although BIM implementation is an expected part of newer construction projects, the technology is ... -
Automatic BIM-model creation of bridge structure using 3D-laser scanning, algorithms and parametric modeling
Daven, Faryad; Ezati, Shahin (MABY;2022, Master thesis, 2022)Bridges have a crucial and huge role in the safety of the public. An important aspect in maintaining the safety of a bridge structure is to have access to a BIM-model that can be used in analysis and facility management. ... -
Automatic reverse modelling of box girder bridge from point cloud data
Knutsen, Torjus Berg; Vaksdal, Fridtjof (MABY;2020, Master thesis, 2020)Building Information Modelling (BIM) has over the last decades brought the physical- and digital worlds closer together. BIM implementation is now expected in construction projects, ensuring interdisciplinary cooperation ... -
