                         pesquisa, foi selecionado o edif{\'{\i}}cio da Cl{\'{\i}}nica 
                         Escola da Terapia Ocupacional \− CETO \− localizado 
                         no Campus da Universidade Federal do Paran{\'a} (UFPR) em 
                         Curitiba, Brasil. A metodologia desenvolvida neste trabalho aborda 
                         o processamento das nuvens de pontos prim{\'a}rias para serem 
                         integradas entre si, gerando cinco modelos de nuvens de pontos do 
                         edif{\'{\i}}cio, sendo eles: (i) ALS +TLS; (ii) ALS + 
                         Fotogrametria de fachada; (iii) TLS + Fotogrametria de telhado; 
                         (iv) Fotogrametria de telhado e fachada; (v) h{\'{\i}}brido 
                         m{\'u}ltiplo - ALS + TLS + Fotogrametria de telhado e fachada. A 
                         partir dos modelos de nuvens de pontos, foram gerados outros cinco 
                         modelos as-is BIM do edif{\'{\i}}cio em LoD3. Os dados ALS foram 
                         processados na plataforma computacional LASTools. As varreduras 
                         TLS foram registradas no software Faro Scene e segmentadas no 
                         software CloudCompare. As nuvens de pontos fotogram{\'e}tricas 
                         foram obtidas por Fotogrametria no software Agisoft PhotoScan. As 
                         integra{\c{c}}{\~o}es das nuvens prim{\'a}rias foram realizadas 
                         com o software CloudCompare empregando o m{\'e}todo de registro 
                         {"}Ponto Mais Pr{\'o}ximo Iterativo{"} (Iterative Closest Point 
                         \− ICP). As modelagens as-is BIM foram realizadas no 
                         software Autodesk Revit. A qualidade das modelagens realizadas foi 
                         verificada por m{\'e}todos de inspe{\c{c}}{\~a}o visual e 
                         compara{\c{c}}{\~o}es com as medi{\c{c}}{\~o}es realizadas em 
                         campo. A integra{\c{c}}{\~a}o das nuvens de pontos 
                         prim{\'a}rias alcan{\c{c}}ou desvios padr{\~a}o inferiores a 15 
                         cm, compat{\'{\i}}vel com a literatura. Os modelos 3D de 
                         edifica{\c{c}}{\~o}es, obtidos de nuvens de pontos baseados em 
                         TLS apresentaram as melhores acur{\'a}cias. O modelo 
                         h{\'{\i}}brido m{\'u}ltiplo as-is BIM n{\~a}o apresentou 
                         car{\^e}ncia de dados, representando adequadamente o 
                         edif{\'{\i}}cio de estudo em LoD3. ABSTRACT: 3D Remote Sensing 
                         techniques contribute to an efficient registration and updating of 
                         constructed buildings through the digital acquisition and 
                         representation of relevant data throughout their life cycle, a 
                         process known as Building Information Modeling (BIM). This work 
                         evaluates different categories of point clouds, obtained from 
                         Light Detection and Ranging (LiDAR) and photogrammetric platforms, 
                         for the construction of as-is BIM models at a level of detail 
                         (LoD) 3 by means of multiple data fusion approaches. LiDAR data 
                         were obtained by Terrestrial Laser Scanning (TLS) and Aerial Laser 
                         Scanning (ALS) platforms, while photogrammetric data by a Remote 
                         Piloted Aircraft (ARP). Data acquisition was carried out for the 
                         Occupational Therapy Clinic School building, located on the Campus 
                         of the Federal University of Paran{\'a} (UFPR) in Curitiba, 
                         Brazil. The building has different blocks with distinct heights, 
                         facade retreats and extended rounded slabs on some of its facades. 
                         All these characteristics in addition to the uneven terrain and 
                         trees in the building surroundings made it difficult to obtain 
                         facade data. The methodology included the processing of primary 
                         point clouds to be integrated with each other, generating five 
                         models of building point clouds: (i) ALS + TLS; (ii) ALS + facade 
                         photogrammetry; (iii) TLS + roof photogrammetry; (iv) roof 
                         photogrammetry + facade photogrammetry; (v) multiple hybrid model 
                         - ALS + TLS + roof and facade photogrammetry. Based on the point 
                         cloud models, five as-is BIM models of the in LoD3 were generated. 
                         ALS data were processed in the LASTools platform. TLS were 
                         registered in Faro Scene and segmented in the CloudCompare 
                         software. Photogrammetric point clouds were obtained by Structure 
                         from Motion (SfM) in Agisoft PhotoScan. Data integration was 
                         performed using CloudCompare tools and the Iterative Closest Point 
                         (ICP) registration method. The as-is BIM modeling was performed 
                         using Autodesk Revit software. The results quality assessment was 
                         verified by means of visual inspection, physical measurements and 
                         deviation analyses. The primary integration point cloud showed 
                         deviations less than 15 cm, compatible with the literature. 
                         TLS-based point cloud models reached the best accuracy. On the 
                         other hand, as-is BIM models solely based on photogrammetry 
                         presented the smallest differences in relation to point cloud 
                         models. The multiple hybrid model-based as-is BIM did not 
                         experience lack of data, and hence, properly represented the 
                         studied building in LoD3.",
