The requirement for reinstating structural integrity to the Holy Aedicule, for preservation of the values it represents and for achieving a sustainable rehabilitation in a demanding environment, demanded a multidisciplinary approach utilizing multispectral monitoring techniques of the successive phases of the Holy Aedicule, prior, during and after the completion of the rehabilitation interventions. Specifically, a thorough geometric documentation was realized involving laser scanning and photogrammetric techniques, in order to obtain a 3D textured model of the Holy Aedicule, prior to the initiation of the works. At this phase, in parallel a diagnostic study was implemented, regarding the building materials and their decay phenomena, utilizing non-destructive techniques that document the surface of the monument and its state of preservation, while providing prospection of its internal structural layers. This information was crucial for the design of the restoration materials and rehabilitation interventions. The next phase involved dismantling of the exterior stone slabs from the facades. The revealed masonry was geometrically documented, to record the morphology of this internal layer and to optimize the design of the required interventions. The geometrical products verified the non-destructive prospection of the Aedicule. During the strengthening interventions the Tomb of Christ was opened, along with an "observation window" within the Tomb Chamber; their interiors were digitally documented, including materials information. Upon completion of the strengthening interventions (grouting, titanium elements, etc.), the columns were reset and the stone facades were reinstalled, and the Aedicule was "freed" from the British metal frame installed seventy years earlier. The final phase involved an interdisciplinary documentation of the rehabilitated structure. |

Abstract | Links | BibTeX | Tags: 3D modelling, Ground penetrating radar (GPR), Holy aedicule @article{Agrafiotis2017b, An interdisciplinary team from the National Technical University of Athens is performing the restoration of the Holy Aedicule, which covers the Tomb of Christ within the Church of the Holy Sepulchre in Jerusalem. The first important task was to geometrically document the monument for the production of the necessary base material on which the structural and material prospection studies would be based. One task of this action was to assess the structural behavior of this edifice in order to support subsequent works. It was imperative that the internal composition of the construction be documented as reliably as possible. To this end several data acquisition techniques were employed, among them ground penetrating radar. Interpretation of these measurements revealed the position of the rock, remnants of the initial cave of the bunal of Christ. This paper reports on the methodology employed to construct the 3D model of the rock and introduce it into the 3D model of the whole building, thus enhancing the information about the structure. The conversion of the radargrams to horizontal sections of the rock is explained and the construction of the 3D model and its insertion into the 3D model of the Holy Aedicule is descnbed. |
