The majority of these tests has in common, that fresh concrete is subjected to some kind of defined flow process on a standardized table-like platform and that the geometrical properties of the material after the flow has ceased is determined by simple means such as measuring the flow cake diameter or its sag. The paper at hand proposes a novel image-based approach for an automatic derivation of concrete properties as part of the flow table test. The image-based method enables a digital evaluation of concrete properties. By combining digital image analysis and deep learning methods, not only the consistency but also an abundance of additional concrete properties can be derived from image data. In this way, the quality control of the fresh concrete can be expanded to include a large number of additional parameters, currently not available to the producer nor to the construction site. This data can be integrated into a digital control loop, with which communication between the concrete producer and the construction site can be automated using highly precise real-time data.","PeriodicalId":100248,"journal":{"name":"Civil Engineering Design","volume":"6 3","pages":"96-105"},"PeriodicalIF":0.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cend.202410011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142429804","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}

This can create safety concerns, particularly with regard to critical components. Detailed documentation and tracking of product characteristics are necessary, as well as outlining the related obligations of the parties involved. Currently, this problem is often addressed by numerous contracts and paper-based building documentation. Blockchain technology could prove to be a future-oriented solution to such use cases. Additionally, so-called Smart Contracts, which are custom-designed applications running on the given Blockchain platform, can be an appropriate way for documentation in the construction and facility management process since they allow distribution of their execution to the entirety of the involved Blockchain participants. Based on this approach, this paper presents a platform solution that provides up-to-date product information on various components. The outcome is a system that facilitates digital documentation on a secure legal foundation, with an interface tailored to the specific terms and conditions of each partner involved in the construction and maintenance process.","PeriodicalId":100248,"journal":{"name":"Civil Engineering Design","volume":"6 3","pages":"84-95"},"PeriodicalIF":0.0,"publicationDate":"2024-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cend.202400022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142430340","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}

Predicting pre-grouting requirements is challenging and relies heavily on the expertise of on-site personnel for decision-making. This paper explores using supervised machine learning (ML) to create a data-driven pre-grouting decision process, aiming to predict “grouting time” and “total grout take.” Tree-based regression models were developed using data from a Norwegian railway project, including typical tunneling data. These models showed limited predictive performance, with R2 scores of 0.40, though a significant relationship was observed. The limited performance highlights the need to identify parameters that significantly impact grouting outcomes rather than indicating the unsuitability of tree-based models. Future research should consider a larger data set and additional parameters, such as more data on rock mass quality, hydrogeological conditions ahead of the face, and human, organizational, and contractual factors. Despite initial findings, supervised ML shows promise in enhancing data-driven decision-making in pre-grouting by using appropriate input features and target variables.","PeriodicalId":100248,"journal":{"name":"Civil Engineering Design","volume":"6 3","pages":"63-73"},"PeriodicalIF":0.0,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cend.202400012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142430230","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 potentials are many, especially in the life cycle phase “operation.” There, the digital twin bridge can serve as an efficient tool in terms of analyses, predictions, control, and monitoring. The goal is optimized maintenance, the importance of which continues to grow in view of the current challenges for civil engineering structures. It is therefore particularly important that relevant stakeholders with their needs and requirements are involved in the conception of the digital twin bridge at an early stage. This approach is being pursued by the German Federal Highway Research Institute (BASt) in various research projects that already cover partial aspects of the digital twin and is also being continued in an ongoing project to develop an overall concept for the digital twin bridge. Possible use cases were collected and assigned to the topics of “operational processes,” “maintenance planning and implementation,” and “strategic life cycle management.” In a workshop, the use cases were discussed and initially ranked by and with stakeholders. The results form an important basis for the elaboration of the modular overall concept of the digital twin bridge and the way into practice.","PeriodicalId":100248,"journal":{"name":"Civil Engineering Design","volume":"6 2","pages":"33-40"},"PeriodicalIF":0.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cend.202400010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141002191","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}
