Falls are the primary safety hazard in construction, with traditional manual inspections being inefficient and error-prone, and existing computer vision methods lacking generalization in complex scenarios. This paper presents the Construction Safety Vision-Language Model (CS-VLM), a framework for construction site fall hazard identification and automated captioning, which integrates ModelScope Swift (MS-Swift) adapters and Low-Rank Adaptation (LoRA) technology for efficient fine-tuning of the Qwen2.5-7B-Instruct model. To support model training, a standardized image-text dataset for fall hazards is constructed using a Bidirectional Encoder Representations from Transformers (BERT) -based natural language conversion method. Experimental results demonstrate that CS-VLM achieves a Consensus-based Image Description Evaluation (CIDEr) score of 1.324, Semantic Propositional Image Caption Evaluation (SPICE) score of 0.391, and hazard identification F1-score of 90.2%, outperforming state-of-the-art methods in complex scenario adaptability while reducing computational costs. This research enables precise, standardized hazard description generation, facilitating proactive safety management and accident prevention in construction environments.

坠落是建筑施工中的主要安全隐患，传统的人工检查效率低下且容易出错，现有的计算机视觉方法在复杂场景下缺乏通用性。本文提出了建筑安全视觉语言模型（CS-VLM），这是一个用于建筑现场坠落危险识别和自动字幕的框架，它集成了ModelScope Swift （MS-Swift）适配器和低秩自适应（LoRA）技术，用于对qwen2.5 - 7b - directive模型进行有效微调。为了支持模型训练，使用基于变形金刚双向编码器表示（BERT）的自然语言转换方法构建了跌倒危险的标准化图像-文本数据集。实验结果表明，CS-VLM在基于共识的图像描述评价（CIDEr）得分为1.324，语义命题图像标题评价（SPICE）得分为0.391，危害识别f1得分为90.2%，在降低计算成本的同时，在复杂场景适应性方面优于现有方法。这项研究使精确、标准化的危险描述生成，促进建筑环境中的主动安全管理和事故预防。

As a critical indicator for evaluating road compaction quality, the Intelligent Compaction Measurement Value (ICMV) still suffers from significant scene dependency and the absence of a unified material-structure coupled evaluation framework, particularly in cross-layer compaction assessment. This paper develops a multi-domain analytical framework that integrates vibration signal time, frequency, and time-frequency features based on field data collected from typical road structures, including soil subgrade, cement-stabilized base layer, and asphalt layers. Rolling pass tracking, compactness prediction modeling, and Shapley additive explanations (SHAP) are employed to identify the generic ICMV applicable to pavement structural layers. Furthermore, comparative analyses are conducted to examine the numerical characteristics and vibration response behaviors of the generic ICMV across various structural layers. Finally, a statistically driven stepwise method is applied to determine the engineering ranges of the generic ICMV, thereby establishing a theoretical paradigm for multi-layer intelligent compaction standards and contributing to the digital transformation of pavement engineering.

作为评价道路压实质量的重要指标，智能压实测量值（ICMV）存在着严重的场景依赖性和缺乏统一的材料-结构耦合评价框架的问题，特别是在跨层压实评价中。本文开发了一个多域分析框架，该框架基于从典型道路结构（包括土壤路基、水泥稳定基层和沥青层）收集的现场数据，集成了振动信号的时间、频率和时频特征。采用滚道跟踪、密实度预测模型和Shapley加性解释（SHAP）等方法，确定了适用于路面结构层的通用ICMV。在此基础上，对通用ICMV在不同结构层间的数值特性和振动响应行为进行了对比分析。最后，采用统计驱动的逐步方法确定通用ICMV的工程范围，从而建立多层智能压实标准的理论范式，为路面工程的数字化转型做出贡献。

Infrared imaging is effective for pavement-crack detection under low-illumination conditions, but the scarcity of infrared datasets hinders its broader adoption. This paper proposes a Physics-Informed Diffusion Model to convert readily available visible-light crack images into physically consistent infrared images. The model integrates physical constraints within a Latent Diffusion Model and employs a Channel-Adaptive Dynamic Gamma Correction (CDGC) method to enhance thermally relevant feature representation. Experiments on a ground-truth infrared test set demonstrate that synthetic data generated by the proposed method substantially improves segmentation performance, achieving Pixel Accuracy (PA) of 0.9678 and Frequency-Weighted IoU (FW-IoU) of 0.9459. By obviating the costly, labor-intensive process of infrared dataset collection, the proposed approach facilitates the widespread adoption of infrared machine vision and visible–infrared fusion systems.

红外成像对于低照度条件下的路面裂缝检测是有效的，但红外数据集的稀缺性阻碍了其广泛应用。本文提出了一种物理信息扩散模型，将现成的可见光裂纹图像转换为物理一致的红外图像。该模型在潜在扩散模型中集成了物理约束，并采用通道自适应动态伽玛校正（CDGC）方法来增强热相关特征表示。在红外地面真值测试集上的实验表明，该方法生成的合成数据显著提高了分割性能，像素精度（PA）达到0.9678，频率加权IoU （FW-IoU）达到0.9459。通过避免昂贵、劳动密集型的红外数据集收集过程，该方法促进了红外机器视觉和可见-红外融合系统的广泛采用。

Although digital technologies are increasingly studied in construction, their specific impacts on productivity remain partially understood. This review aims to investigates the relationship between digital technologies and construction productivity. The methodology comprises a bibliometric analysis and a systematic literature review of studies published over the past decade. Scopus was selected as the primary database for data retrieval, with 346 publications across 16 journals being identified and analyzed. The bibliometric analysis reveals publication trends and technology interrelations, highlighting AI and optimization as central to a cohesive ecosystem involving BIM, digital twins, sensors, and robotics. The systematic literature review is structured around categorising the use of technology for productivity into four dimensions: measurement, estimation, optimisation, and enhancement. Despite this qualitative synthesis being influenced by the authors' judgement and subjectivity, it highlights the practical benefits such as improved prediction and automation, alongside challenges including data standardization, integration, and workforce adaptation.

This paper integrates AI image recognition and BIM technology to develop a prototype system that achieves automation and visualization of construction progress control. The system supports using a BIM model for planning deployment of multiple surveillance cameras to encompass the entire construction site. The real-time images captured by these cameras are processed using object detection technology to locate all actively constructed objects in the images and identify their respective construction phases. By integrating the perspectives of these cameras into the BIM model, the AI detection results from each camera image are automatically inputted into corresponding components of the BIM model. Subsequently, the real-time site progress information stored in the BIM model is compared with the planned schedule, and the comparative results are visually presented on the BIM model components in different colors. Through visualization, this approach enables management personnel to control progress in a specific and intuitive manner in real-time.

Previous research on mining dumper activity recognition has rarely explored edge devices for classifying processed vibration signals from deployed Convolutional Neural Network (CNN) models. Most studies have relied on remote or cloud-based platforms, limiting applicability in mines due to unreliable connectivity. This paper introduces an on-device classification approach for dumper activities from processed vibration signals by deploying trained CNN models on edge devices. Vibration signals collected were processed using signal processing methods to extract distinct features for classification and validated through SHAP 3D surface visualization. Among tested models, the combination of ResNet50 with DWT-GT achieved optimal performance, delivering 99.23% accuracy with low computational complexity. Deployment on resource-constrained devices demonstrated feasibility of edge-based computation, where BeagleBone AI-64 achieved 67.46% lower CPU time. These findings establish the feasibility of edge devices for real-time dumper activity recognition, eliminating dependency on external platforms and enhancing operational efficiency in mining environments.

以往关于矿用自卸车活动识别的研究很少探索利用卷积神经网络（CNN）模型对处理后的振动信号进行分类的边缘设备。大多数研究都依赖于远程或基于云的平台，由于连接不可靠，限制了在矿山中的适用性。本文介绍了一种通过在边缘设备上部署训练好的CNN模型，从处理过的振动信号中对翻车机活动进行设备上分类的方法。采用信号处理方法对采集到的振动信号进行处理，提取明显特征进行分类，并通过SHAP三维表面可视化进行验证。在测试的模型中，ResNet50与DWT-GT的组合获得了最佳性能，准确率达到99.23%，计算复杂度较低。在资源受限设备上的部署证明了边缘计算的可行性，其中BeagleBone AI-64的CPU时间降低了67.46%。这些发现确定了边缘设备用于实时卸料器活动识别的可行性，消除了对外部平台的依赖，提高了采矿环境中的操作效率。

Effective reuse of creative ideas from value engineering (VE) workshops is crucial for cost-effective, innovative design. Conventional methods like post-project reviews and keyword searches often lack context, real-time availability, and semantic relevance, limiting the practical reuse of past insights. This paper addresses the fundamental question of how knowledge generated during VE workshops can be effectively captured and reused to support future idea generations. To solve this, it proposes an integrated methodology combining BIM-based live capture with a hybrid retrieval system. This system uses structured attributes and Bidirectional Encoder Representations from Transformers (BERT) based semantic similarity to ensure context-aware reuse. A prototype Revit plug-in was developed for structured capture and semantic search. Evaluation demonstrated strong performance, superiority over baseline methods, and high user acceptance. This paper provides a practical framework and tool for structured documentation and intelligent knowledge reuse, thereby enhancing creativity support for construction VE practices.

Stakeholder-centric whole-lifecycle framework for guiding the development and implementation of construction digital twins 以利益相关者为中心的全生命周期框架，用于指导建筑数字孪生的开发和实施

Construction Digital Twins (CDTs) are increasingly recognised for their potential to improve construction project management. However, successful implementation requires more than just deploying technology; it demands a stakeholder-centric, whole-system lifecycle approach. Existing frameworks are largely technocentric, focusing on technical demonstrations in isolated use cases and offering limited guidance on stakeholders' roles, interactions, and system lifecycle considerations. To address these gaps, this paper introduces a socio-technical CDT framework spanning five lifecycle stages: Define, Design, Deploy, Refine, and Decommission. Grounded in an eight-month longitudinal industrial case study and informed by a CDT triad taxonomy (applications, data, technologies), the framework guides CDT development and maps stakeholder engagement throughout its lifecycle. Stakeholders are categorised into four actor groups: Strategic, Advisory, Technical, and Operational, whose interdependencies are conceptualised through an actor role model. The framework extends CDT applicability beyond controlled demonstrations to real project contexts, while emphasising the need for validation across diverse organisational settings.

建筑数字孪生（CDTs）因其改善建筑项目管理的潜力而日益受到认可。然而，成功的实施需要的不仅仅是部署技术；它需要一个以涉众为中心的全系统生命周期方法。现有框架在很大程度上是以技术为中心的，关注于孤立用例中的技术演示，并提供有关涉众角色、交互和系统生命周期考虑的有限指导。为了解决这些差距，本文介绍了一个跨越五个生命周期阶段的社会技术CDT框架：定义、设计、部署、改进和退役。该框架以为期8个月的纵向工业案例研究为基础，并以CDT三元分类（应用程序、数据、技术）为依据，指导CDT开发，并在其整个生命周期中绘制涉众参与的地图。涉众被分为四个行动者组：战略、咨询、技术和运营，其相互依赖关系通过行动者角色模型概念化。该框架将CDT的适用性从受控的演示扩展到实际的项目环境，同时强调了跨不同组织设置进行验证的必要性。

This paper proposes a lightweight semantic segmentation framework utilizing 3D point cloud data to enable automatic and rapid construction progress monitoring in high-rise building projects. This study centers on developing an efficient L-PointNet++ model that integrates self-attention mechanisms and MobileNetV3 modules, significantly reducing computational complexity and achieving a 95.63 % reduction in total training time compared to traditional PointNet++. A dual-stage training strategy is adopted to effectively address class imbalance, resulting in high segmentation accuracy with mean Intersection over Union (mIoU) values of 0.9308 for edge points and 0.9300 for corner points. Experimental results indicate that the developed framework can significantly enhance the speed and adaptability of as-built BIM model reconstruction and provide substantial improvements in decision-making efficiency and project management through the implementation of a visualization-based progress monitoring and early-warning system. Overall, the proposed approach demonstrates notable advantages in 3D reconstruction accuracy, speed, and project control, providing a robust solution for real-time construction progress monitoring applications.

Experimental results indicate that the developed framework can significantly enhance the speed and adaptability of as-built BIM model reconstruction and provide substantial improvements in decision-making efficiency and project management through the implementation of a visualization-based progress monitoring and early-warning system. Overall, the proposed approach demonstrates notable advantages in 3D reconstruction accuracy, speed, and project control, providing a robust solution for real-time construction progress monitoring applications.</div></div>","PeriodicalId":8660,"journal":{"name":"Automation in Construction","volume":"183 ","pages":"Article 106765"},"PeriodicalIF":11.5,"publicationDate":"2026-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145995538","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}

Vibration monitoring of engineering infrastructures is indispensable for structural safety and scientific maintenance. Distributed acoustic sensing (DAS) has been increasingly adopted in engineering field, owing to its attractive characteristics over conventional point-based transducers, including high spatial resolution, spatial continuity, non-invasiveness and superior stability. These advantages align well with instrumentation requirements for long-term and widely-distributed vibration monitoring in large-scale infrastructures. Accordingly, this paper provides a systematic review of DAS technique with respect to sensing mechanisms, deployment strategies, signal analysis, and typical applications. This review is structured around a complete operational workflow that explicates what the technology is, how it works, and what it enables in practice. Furthermore, current challenges and promising directions are discussed to envisage the widespread implementation of DAS systems, with the ultimate goal of automated monitoring for infrastructures. This review also aims to provide an exhaustive reference for researchers, professionals or engineering inspectors seeking state-of-the-art in DAS research.
