A Proposed Circular Economy Readiness Framework for the Rail Sector, A Literature Review and Conceptual Framework

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The circular economy (CE) offers a transformative approach to addressing global sustainability challenges, yet few frameworks integrate it with business strategy, systems thinking (ST) and asset management (AM), especially within critical infrastructure sectors like rail. This paper conducts a comprehensive literature review to assess existing

Digital documentation of railway tunnel inspection in Austria

open access: yesCivil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.
Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.

Rock Mass Anomaly Detection with a Variational Autoencoder in Tunnel Boring Machine Data

open access: yesCivil Engineering Design, EarlyView.
Abstract This study presents an unsupervised machine learning approach to rock mass anomaly detection in tunnel boring machine operational data using a Variational Autoencoder combined with bidirectional Long Short‐Term Memory cells. The model was trained on TBM data from the Brenner Base Tunnel project, with minor faults and geotechnically relevant ...

In‐situ installation safety of post‐installed anchorages—Investigations on construction sites

open access: yesCivil Engineering Design, EarlyView.
Abstract The sensitivity to reduced installation effort of post‐installed fastening systems is determined during the product qualification through robustness tests conducted under controlled laboratory conditions. Using the concept of required α‐factors, the installation safety factor γinst is determined and provided as an essential characteristic in ...
