The project involves the construction of a pressure tunnel connecting the Kühtai and Finstertal reservoirs, incorporating concrete linings with and without sealing membrane as well as steel linings. The sensors were accurately installed individually to each lining type, overcoming problem statements such as positioning sensors on unreinforced concrete without damaging the sealing foil or compromising the structural integrity. The monitoring system enables real-time data collection on strain and temperature variations during key phases, including concreting, prestressing, pressure, or filling tests. This approach illustrates the effectiveness of integrating fiber optic technology into hydropower infrastructure, offering enhanced monitoring accuracy and improved decision-making for maintenance and operational strategies.

This study assesses the generalization abilities of K-nearest neighbors, support vector regression, artificial neural networks, random forest, classification and regression trees, and extreme gradient boosting (XGBoost) for predicting penetration rate (PR) and explores the potential of incremental learning to enhance it. The datasets were collected from two tunnels (Line C and Line S) that were constructed in similar geological formation, with similar technology, in Porto, Portugal. In the first part, these models are trained using Line C data and applied to Line S for generalization assess under different splitting and scaling methods. XGBoost demonstrated superior performance in both accuracy and generalization, making it the base model for incremental learning. In the second part, the incremental learning, applied by continually updating the XGBoost model when new data becomes available, was evaluated across different PR ranges and different incremental sizes. Finally, the model trained using Line C data plus Line S data was compared to the model using Line S only to investigate the impact of including Line C data on generalization. Our findings show that for the imbalanced data of PR <125 mm/rpm, incremental learning show unstable generalization but exhibited improved generalization on PR < 25 mm/rpm. For the balanced data of PR <25 mm/rpm, incremental learning showed more stable and gradually improved generalization. Combining Line C data with Line S data for training improved generalization significantly. The study results provide important insights into developing generalization strategies, highlighting the benefits of pre-training with similar data and the challenges of dealing with imbalanced data in real-life projects.","PeriodicalId":100248,"journal":{"name":"Civil Engineering Design","volume":"7 2","pages":"63-84"},"PeriodicalIF":0.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cend.202400047","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144299645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ground consists of unconsolidated sand, and the conventional tunneling method will be used. Two main challenges need to be addressed: (1) The tunnel passes near wetlands inhabited by sensitive species and invaluable ecosystems, necessitating hydraulic and perimeter surveys to assess the potential impact of excavation on the environment. To mitigate these effects, the tunnel alignment was planned to avoid sensitive wetland areas. A waterproof structure was also designed, incorporating a 3D shell-spring analysis and reinforced bar placement at critical crossings. A Building/Construction Information Modeling, Management model was also developed for precise planning. (2) The tunnel portal is located near residential areas, requiring careful consideration of the surrounding environment. 3D simulations were conducted to evaluate noise levels in the temporary yard to manage noise pollution, and soundproofing measures were implemented. A 3D noise map was also created to facilitate clear communication with residents during explanatory meetings, ensuring transparency and minimizing disturbance. These solutions ensure the project progresses with minimal environmental and residential impact.","PeriodicalId":100248,"journal":{"name":"Civil Engineering Design","volume":"7 3","pages":"113-123"},"PeriodicalIF":0.0,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cend.202400037","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its implementation can potentially hold significant advantages for the built environment, particularly in manufacturing and building product usage aligned with Building Information Modeling (BIM). This paradigm shift toward decentralized transactions can foster security, reliability, and accountability. Hyperledger Fabric (HLF), an enterprise-grade distributed ledger, offers a modular, scalable, and confidential digital framework. This article introduces HLF-based workflows to address inefficiencies in BIM and fastener product lifecycle management, such as fragmented data handling and limited process automation. Leveraging chaincodes linked to BIM models, HLF simplifies, enhances transparency, and automates construction product lifecycle processes. Contract data and execution details are managed through a blockchain stored in a common data environment (CDE) and linked to chaincodes. The article presents the conceptualization and implementation of automated workflows, emphasizing efficiency and transparency. While showcasing successful deployments, it also highlights areas for future improvement and development. The proposed framework represents a pioneering step toward a decentralized cooperative environment in the construction industry, aligning with the transformative potential of blockchain technology.","PeriodicalId":100248,"journal":{"name":"Civil Engineering Design","volume":"7 1","pages":"9-22"},"PeriodicalIF":0.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cend.202400027","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of active learning in parallel with GWO significantly reduced the number of calls to the objective function and increased the accuracy of the algorithm's search in the problem space. The proposed approach was first evaluated on four benchmark problems, and its performance was validated against original GWO, particle swarm optimization (PSO), and genetic algorithm (GA) techniques. Then, by generating artificial damage scenarios on a real jacket platform in ABAQUS software, it was evaluated for the identification of damaged members. The results indicated high accuracy in estimation and an appropriate convergence rate in solving the high-dimensional and complicated problem of damage detection of jacketed platforms. In such a way that the error rate of damage severity estimation in scenarios 1 and 2 was, on average, 3% and 5%, respectively. Meanwhile, the damage position was correctly estimated, and the call rate of the function was reduced by 50%. The efficiency of the proposed approach shows that it can be used for further works on the reliability-based design of jacket structures.","PeriodicalId":100248,"journal":{"name":"Civil Engineering Design","volume":"7 1","pages":"36-48"},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cend.202400032","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. In rail networks, comprehensive preparations are necessary to be able to plan closures and required compensation measures. To optimize this process, a workflow for a digital inspection was generated to allow a rapid localization and a corresponding time advantage when conducting the activities on site. In doing so, a multitude of bases can be used, a standardization of damage patterns is carried out and a collaborative cooperation of multiple inspection personnel is possible. Depending on the data stock, digitized as-built models in the form of a plan, digital plan documents and existing or generated digital twins can be used. Making it possible to locate a damage already during the inspection and thus enable a comprehensible documentation and an automated generation of reports. The pre-set options for attribution of damages enables a time-optimized inspection on site—which enables a reduction of the required time, the associated restrictions on traffic routing and at the same time reduces the susceptibility to errors.

Accurate liquefaction assessment is vital for geotechnical engineering, as it informs the design and mitigation strategies needed to safeguard infrastructure and reduce the risk of catastrophic failures. To enhance the accuracy of classification problems associated with liquefaction, we employ ensemble methods, leveraging diverse machine learning techniques such as support vector machines, stochastic gradient descent, multi-layer perceptron neural networks, K-nearest neighbors, and decision trees. The research encompasses data exploration and a subsequent division for performance assessment, followed by hyperparameter tuning through GridSearchCV to optimize model effectiveness. Among the ensemble methods employed, AdaBoost stands out as the most accurate, achieving precision of 85%, recall of 84%, F1 score of 83%, Jaccard index of 72%, and overall accuracy of 84%. However, K-nearest neighbors and decision trees exhibit higher false negative values compared to other methods. Notably, both ensemble approaches provide acceptable estimations, with false negative values ranging from 0 to 1 and false positive values between 7 and 10. The decision tree, while predicting the lowest false positive rate, has a higher false negative count, rendering it less favorable for practical applications.","PeriodicalId":100248,"journal":{"name":"Civil Engineering Design","volume":"7 1","pages":"23-35"},"PeriodicalIF":0.0,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cend.202400024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
