“…The surveying integrated 3D laser scans with a high level of detail (0.5 × 0.5 cm) and the photographic images in order to have very accurate information about the dimensions and the state of conservation of the architectural masses. The next stage of data processing was necessary because surveying data are not selective, and sometimes it is not possible to have all the necessary information [30][31][32]. Moreover, the construction of libraries of digital objects presupposes the inevitable comparison with the variability and uniqueness of the built environment, especially when it has ancient origins, or is the result of the stratification of different interventions, or is found in a poor state of preservation.…”

BIM (Building Information Modeling) processes are the most effective way to know existing architectural structures, integrating the most advanced potentials of 3D modeling and the structured storage of heterogeneous information. Many HBIM (Heritage Building Information Modeling) applications lead to the systematization of survey data, even though a univocal working method is not yet clearly defined. This research considers the decomposition of architecture, based on structured criteria, and its reconstruction, through ideal models, as the main moments of the HBIM process. This hypothesis is verified through a procedure that links the survey 3D data with the characteristics of the ideal HBIM model, which allows a continuous comparison between the project model and as-built. The research provides for the setting up of a general methodology that, according to a growing approach to the complexity of the analyzed buildings, compares the process followed on two architectural structures. The study analyzes some important HBIM issues: The relationship between the semantic modeling and the surfaces' continuity of architectural heritage; the relationship between the elements standardization, geometric irregularities, and material heterogeneity; the reliability of the built models; and the evaluation of the gap between an ideal model and the objective accuracy of surveying.

Building information modeling (BIM) has received significant research attention in the field of built heritage. As-built BIM refers to a BIM representation of the "as-is" conditions of built heritage at the time of a survey. Determining the level of development (LoD) is crucial for as-built BIM owing to its relevance to model effects and modeling efforts. This study addresses this issue from the viewpoint of a brick structure based on a case study of a fifteenth-century ruin in Nanjing, China. Three LoDs are proposed based on the combined use of a commercial platform and auxiliary tools: A host model linked with raster images composed using orthoimage and relief maps (LoD 1), an as-built volume with semantic skins (LoD 2), and a brick-by-brick model with custom industry foundation class parameters at local areas (LoD 3). The results reveal that LoD 1 caters to an efficient web-based workflow for brick-damage annotations; as-built dimensions can be extracted from LoD 2; and LoD 3 enables attributes, such as damage types, to be attached at the brick level. In future studies, the detection of brick shapes is expected to automate the process of as-built surface mapping.

“…These critical aspects are probably due to the closeness with the release of the last Freecad version; as a consequence some complementary addons have not been adapted to new libraries yet but this gap is presumable/desirable that it can be shortly filled. The state of art concerning studies focusing on Freecad BIM features is limited and often related to themes not strictly linked to the 4D BIM Modelling (Falck et al, 2012, Logothetis et al, 2017a, Logothetis et al, 2017b, Logothetis et al, 2018.…”

Abstract. The paper aims to investigate the potential inherent in a FOSS (Free and Open Source Software) approach for the 4D BIM modelling using Freecad. In order to reach this goal it shows a comparison of Freecad features with those of commercial software, considering the evaluation of the effective application of this Open Source software in the professional environment, and highlighting the progress in the FOSS BIM area, that still represents an unexplored study field if compared to the vast publications related to BIM modelling that occurred in the last two decades. To this end, the study has been carried out on a singular case study, a steel canopy which has been designed for the urban renewal of a public space in Teramo. Despite its size, the canopy required the definition of complex details. Its structural system has addressed the study to compare Freecad with some software dedicated to steel structures or particularly suitable for the modelling of this specific structural typology: Tekla Structures and Sketchup. Starting from a concise historical reconstruction of the FOSS spread, the paper introduces a brief overview of the potential of Freecad in terms of BIM modelling - also proposing an operational modality to facilitate the drawing of BIM elements within the software - and finally reaching to the examination of three simulations which has been carried. This comparison can be useful to establish the current state of development of Freecad in the field of 4D BIM.
