smartBridge Hamburg - prototypische Pilotierung eines digitalen Zwillings

smartBridge Hamburg - prototypical piloting a digital twin Cyclic inspections by hand according to DIN 1076 are the basis for planning maintenance and repair measures for our engineering structures. The calculation of condition ratings is performed based on detected deficiencies. The documentation of the inspection is done primarily within the program system SIB-BW. The system offers a comparably uniform rating standard and enables a limited retrospective and prospective view for maintenance planning. New developments like BIM or continuous, sensor-based monitoring, which is established in other branches, are not yet conceptually integrated. In light of the digital transformation the question arises how the well established manual and the digital assessment as well as BIM generated data can be unified within one continuous process chain and which benefits can by created by doing so. Therefore, the Hamburg Port Authority (HPA) has initiated the smartBridge Hamburg project which prototypically tests the concept of the digital twin using the Koehlbrandbruecke in Hamburg. The digital twin is used to conceptually unify the BI-model as well as analogue and electronic assessment data and to provide aggregated data in a form that meets the needs of different user groups. This paper presents premises and basic considerations prior to project initiation.
