不确定性感知隧道状态评估博士生

100%, Zurich, fixed-term print The Chair of Infrastructure Management, led by Professor Dr. Bryan T. Adey within the Institute of Construction and Infrastructure Management of the Department of Civil, Environmental and Geomatic Engineering, has an opening for a doctoral student. This position focuses on transforming heterogeneous inspection and monitoring evidence into uncertainty-aware condition indicators for tunnel structures and mechanical, electrical, and plumbing systems within a digital twin. This position is part of an interdisciplinary SNSF project in collaboration with the Free University of Bozen-Bolzano, the Hagerbach Test Gallery, and the EuroTube Foundation. The preferred starting date is 1 February 2027, although other dates are negotiable. Project background Tunnels are critical links in transport networks, and many Swiss road and rail tunnels are ageing while being subject to increasing traffic loads, climate-related stressors, and evolving safety requirements. Their maintenance involves two interdependent asset domains, namely structural elements, such as lining, portals, and drainage, and mechanical, electrical, and plumbing systems, such as ventilation, lighting, and fire detection. In current practice, these domains are managed largely in isolation, inspections remain heavily manual, and evidence from different campaigns, sensors, and specialists is fragmented across separate reports and databases. Interventions are therefore often planned using disjointed evidence and conservative heuristics, even where substantial data exist. The project Predictive, Resilient, Integrated Systems for Management of Tunnel (PRISM-T), funded by the SNSF, addresses this challenge through an integrated digital twin workflow for tunnel maintenance decision support. Heterogeneous inspection and monitoring evidence is transformed into uncertainty-aware condition indicators, which are used to update risk, to assess whether additional information is worth collecting, and to derive executable intervention programs. Extended reality (XR) is used to validate decisions and to guide inspection and maintenance work on site. The workflow is developed and validated in the Tunnel Digitalisation Centre of the Hagerbach Test Gallery in Flums, and its transferability is tested at the DemoTube facility of the EuroTube Foundation in Dübendorf. Regular field work at both sites and close collaboration with the partner team in Bolzano form an integral part of the doctoral research. Within this project, the doctoral position addresses the evidence layer of the workflow, in which inspection images, 3D laser scans, and sensor data are transformed into condition indicators that form the basis for the risk updating and intervention planning carried out in a companion doctoral position. Job description The successful candidate will develop methods to extract defect and deterioration indicators from inspection images, video, sensor data, and periodic 3D laser scans, including domain adaptation for tunnel environments and time-lapse change detection. Evidence from multiple sources will be fused into asset-level condition indicators using a hierarchical Bayesian framework, and uncertainty models and evidence quality flags will be developed for each source. The candidate will contribute to defining the condition indicator types in the digital asset model, to integrating the indicators into the digital twin prototype, and to inspection and validation campaigns at the Hagerbach Test Gallery and the EuroTube Foundation.
