    Parametric modelling approach to reconstructing architectural indoor spaces from point clouds
    (ISPRS, 30.06.2021) Wahbeh, Wissam; Wahbeh, Wissam [in: The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences]
    Abstract. In this paper, some outcomes of a research project which aims to introduce automation to speed up modelling of architectural spaces based on point clouds are presented. The main objective of the research is to replace some manual parametric modelling steps with automatic processes to obtain editable models in BIM-ready software and not to generate non-parametric IFC (Industry Foundation Classes) models. An approach of automation using visual programming for interior wall modelling based on point clouds is presented. The pipeline and the different concepts represented in this paper are applicable using different programming languages but here the use of Rhinoceros as a modelling software and its open-source visual programming extension "Grasshopper" is intentional as it is in common use for parametric modelling and generative design in architectural practice. In this research, it is assumed that there is a predominance of three mutually orthogonal directions of the walls in the interior spaces to be analysed, which is the case of most indoor spaces.

    Digital twinning of the built environment. An interdisciplinary topic for innovation in didactics
    (Copernicus, 03.08.2020) Wahbeh, Wissam; Kunz, Dominique; Hofmann, Joachim; Bereuter, Pia; Wahbeh, Wissam [in: ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences]
    The concept of a Digital Twin (DT) takes an increasingly important role in the construction industry and related research fields. It is a concept associated with Industry 4.0; however, the scientific literature does not provide a unique and clear definition of this concept. This paper aims to analyse the definitions of the digital twin to clarify this concept in the related fields of architecture, engineering and construction (AEC). Moreover, this work proposes and employs the concept of a Digital Twin as an objective for a project-based learning approach in a didactical setting. As an interdisciplinary approach, this work demonstrates the potential impact on the traditional didactical frameworks in the educational domain of construction and its value as an opportunity to introduce interdisciplinary expertise to all students in these fields. This work presents a use case applying the concept at the School of Architecture, Civil Engineering and Geomatics of FHNW.

    3D survey and digital models as the first documentation of hypogeum of S. Saba in Rome
    (Springer, 08.10.2018) Wahbeh, Wissam [in: Applied Geomatics]
    On the Aventine Minor, the oratory of Santa Silvia was home to a community of oriental monks, who, in the first half of the seventeenth century, created a typical Palestinian cemetery with a small monastery that expanded with the growing prestige of the community. The construction of the Basilica of San Saba, above the oratory, was by a group of monks, “the Benedettini di Montecassino,” who lived there in the middle of the tenth century. The substructure was only recovered in the early 1900s. The study of this architectural structure is particularly interesting because there were no complete surveys and the available documentation, as far as we know, was limited to a graphical plan and section. For this reason and due to the archeological significance, it has been selected as a national research project (PRIN 2010–2011). The research has requested detailed documentation through laser scanning and photographic-based documentation. The goal of the present work is to produce a documentation of the oratory from CAD model to the BIM construction.
