The Rehabilitation of the Old Medina of Bejaad, Morocco: a Technological Approach (BIM) to Enhance the Built Heritage

Objective: This study proposes a process of revitalization and regeneration of the old medina of Bejaad, as well as a methodology for the technical analysis of its urban fabric and traditional structures, while respecting the inherent values of its constructions. Through data related to the location of each building and a more in-depth investigation, a global relationship with its environment and history is established. Theoretical Framework: The old medina of Bejaad, through its ancient fabric and its potential social and economic wealth, should be leveraged for the development of this spiritual city. This built heritage is characterized by buildings that, for the most part, have preserved an uncommon restraint, maintaining the art of past construction and the secrets of local housing. Its housing is composed of two types of built fabric: traditional and more recent structures. These two types of buildings are connected by a network of public spaces that bring the inhabitants together. Method: Creation of specific Building Information Modelling (BIM) object libraries, derived from three-dimensional models created by 3D scanning using Lidar technology. Results and Discussion: The results of this investigation highlight the need to identify new methodologies for studying the built environment, which no longer focus solely on individual building types, but encompass the broader scale of the fabric, within which it is possible to assess the constructive relationships between the elements composing the block. This is achieved through a process of adopting measures for the protection, rehabilitation, and appropriation of their living environment. Originality/Value: The study proposes a practical evaluation approach by providing precise data to improve the preservation of the built heritage of the old medina of Bejaad, with the aim of establishing an architectural, urban, and landscape charter for the city and its components.
