The Chair of Construction Heritage and Preservation is working on the set-up of a digital building components archive. The aim is to systematically collect and record essential construction details and building components on a long-term basis in order to provide support for measures for the repair and maintenance/restoration of structurally challenging or highly complex objects, while at the same time tracing the history of changes in construction. Both historical and contemporary details will be investigated and visualized. This digital archive allows to be linked to more comprehensive information and existing component catalogues, as well as directly to the ETH Material Hub and thus to the nationwide network
