OMSTTN integrates a hybrid Transformer offline model with a parallel embedding layer to process diverse monitoring attributes and employs a Spatial-Temporal Transformer block to capture complex spatiotemporal correlations. An online learning mechanism enables dynamic adaptation to evolving conditions, enhancing prediction accuracy. Validated on a real-world XuZhou Rail Transit project, OMSTTN achieves strong prediction performance (MAE: 0.0461, RMSE: 0.0699, R<ce:sup loc=\"post\">2</ce:sup>: 0.9441). Comparative experiments demonstrate its effectiveness in handling multi-attribute data, dynamic changes, and spatiotemporal patterns. In short, OMSTTN narrows the research gap by providing a spatiotemporal framework for accurate risk prediction, offering significant potential for early risk detection and proactive management in excavation engineering.","PeriodicalId":8660,"journal":{"name":"Automation in Construction","volume":"55 1","pages":""},"PeriodicalIF":10.3,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dynamic programming is applied to allocate adjustments between tamping and fine-tuning. Experiments reveal that reducing 10 m and 5/30 m chord offset limits to 0.4 times improves dynamic performance over manual schemes.

This paper presents a method for assessing shield-tunnel segment quality using a copula model with numerical simulation. A two-dimensional joint probability-distribution model is developed to model influencing factors, establishing a reliability-based evaluation system for segment assembly quality. Key steps include tunnel section division, marginal and copula function selection, and reliability assessment, focusing on a large submarine-shield tunnel. A Monte Carlo simulation examines the impact of various copula models on reliability estimates, validating the proposed method. Key findings show that (1) the selection of marginal and copula functions significantly affects segment assembly quality and reliability, with the commonly used Gaussian copula not always being optimal, and (2) failure probabilities can vary by up to 84 times due to differing construction conditions and geological factors across tunnel sections.","PeriodicalId":8660,"journal":{"name":"Automation in Construction","volume":"96 1","pages":""},"PeriodicalIF":10.3,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanical models of the cable-driven and rotatable joints were established, and the relationship between motor input torque and end force was determined. The experimental results show that the climbing robot designed in this paper exhibits strong adaptivity on a variety of different materials and different shapes of climbing surfaces, and has strong climbing stability.

While deep learning presents a promising solution, existing research often relies on limited real-world labeled data. This paper introduces a framework to train a deep learning model for on-site rebar instance segmentation without human labeling. Synthetic data are generated from BIM models, creating a Synthetic On-site Rebar Dataset (SORD) with 25,287 labeled images. Domain adaptation is incorporated to bridge the gap between synthetic and real-world non-labeled data. This approach eliminates the need for human labeling. It significantly enhances model performance, achieving a threefold improvement in Average Precision (AP) metrics compared to models trained on limited real-world data. Additionally, the proposed method demonstrates superior performance across various on-site rebar images collected online, underscoring its generalizability and practical applications.","PeriodicalId":8660,"journal":{"name":"Automation in Construction","volume":"8 1","pages":""},"PeriodicalIF":10.3,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142987833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the low level of automation and insufficient adaption of the flight path in response to environmental obstacles, a method of automatic planning UAV inspection mission based on the Geometric Digital Twin (GDT) model and Voxelized Obstacle Information (VOI) is proposed. First, a method for shifting the Field of View (FOV) centroids in parallel is proposed to efficiently generate inspection waypoints. Second, a waypoints adjustment method based on environmental VOI of 3D point clouds is proposed to address the safety issues. Third, a method combining Genetic Algorithm (GA) with A* based on VOI is proposed for optimizing UAV flight path to avoid real-world obstacles.

The diversity in the topologies and behaviors of structural components further presents considerable obstacles to effective machine learning applications in design. This paper introduces an approach using heterogeneous graph neural networks (HetGNNs) to automate and optimize the dimensioning of frame components. This method captures the distinct frame topologies by developing a precisely tailored heterogeneous graph node representation. Leveraging a unique dataset derived from engineering drawings, the HetGNN model learns to size the component sections accurately. It is demonstrated that this method offers a transformative improvement in the efficiency, accuracy, and cost-effectiveness of structural design while adhering to design standards. The size design of RC frame structures can be completed in under one second, with an average size deviation of around 50 mm (one module) compared to those designed by engineers.","PeriodicalId":8660,"journal":{"name":"Automation in Construction","volume":"30 1","pages":""},"PeriodicalIF":10.3,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142987829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improperly selecting operational parameters may result in excessive wear and reduced cutting performance, leading to longer project duration and increased costs. Furthermore, it is still challenging to balance cutter wear and cutting performance. To address these issues, a multi-objective optimization (MOO) framework based on the Light Gradient Boosting Machine (LightGBM) algorithm and the enhanced non-dominated sorting genetic-II (NSGA-II) algorithm is proposed to predict and optimize the cutter wear and cutting performance. To validate this framework, a shield tunneling project in China is presented.
