DURAARK - Durable Architectural Knowledge




Long-term preservation of architectural building data is crucial to guarantee the legal abilities of allstakeholders (e.g. designer, engineers), to provide the ability to retrofit legacy buildings, to preserve cultural heritage, to ensure security precautions, and to enable knowledge-reuse of design and engineering solutions.

With the recent paradigm shift in architecture and construction from analog 2D plans and scale models to digital 3D building models, long-term preservation efforts must turn their attention to this new type of data. Currently, no existing approach is able to provide a secure and efficient long-term preservation solution covering the broad spectrum of 3D architectural data, while at the same time taking into account the demands of institutional collectors like architecture libraries and archives as well as those of the private sector including building industry SMEs, owners and operators.

DURAARK is to tackle these challenges by developing long-term preservation tools that are tailored to the requirements of 3D content. Persistent and future-proof data usage will be ensured by automated generation of consistent metadata. Thereby, DURAARK will be the first long-term preservation project coveringthe whole spectrum of 3D architectural content ranging from raw point clouds up to extensively annotated 3D BIM (Building Information Modeling) models.

University of Bonn Tasks

Within DURAARK, the Computer Graphics group's tasks include the following:

  • documenting the changing state of built architecture
  • registration of low-level point cloud scans and high-level BIM models to enable the transfer of structure and semantics
  • recognition of meaningful shapes and structures in legacy building representations
  • development of point cloud compression that or compliant with long-term archival
