Experimental Study on Using Synthetic Images as a Portion of Training Dataset for Object Recognition in Construction Site

The application of Artificial Intelligence (AI) across various industries necessitates the acquisition of relevant environmental data and the implementation of AI recognition learning based on this data. However, the data available in real-world environments are limited and difficult to obtain. Construction sites represent dynamic and hazardous environments with a significant workforce, making data acquisition challenging and labor-intensive. To address these issues, this experimental study explored the potential of generating synthetic data to overcome the challenges of obtaining data from hazardous construction sites. Additionally, this research investigated the feasibility of hybrid dataset in securing construction-site data by creating synthetic data for scaffolding, which has a high incidence of falls but low object recognition rates due to its linear object characteristics. We generated a dataset by superimposing scaffolding objects, from which the backgrounds were removed, onto various construction site background images. Using this dataset, we produced a hybrid dataset to assess the feasibility of synthetic data for construction sites and to evaluate improvements in object recognition performance. By finding the optimal composition ratio with real data and conducting model training, the highest accuracy was achieved at an 8:2 ratio, with a construction object recognition accuracy of 0.886. Therefore, this study aims to reduce the risk and labor associated with direct data collection at construction sites through a hybrid dataset, achieving data generation at a low cost and high efficiency. By generating synthetic data to find the optimal ratio and constructing a hybrid dataset, this research demonstrates the potential to address the problems of data scarcity and data quality on construction sites. The improvement in recognition accuracy of the construction safety management system is anticipated, suggesting that the creation of synthetic data for constructing a hybrid dataset can reduce construction safety-accident issues.

How to reduce construction risks in rural areas: an evolutionary game analysis

PurposeThe construction industry is widely recognized as one of the most hazardous sectors in the world. Despite extensive research on safety management, a critical issue remains that insufficient attention is devoted to safety practices in rural areas. Notably, accidents frequently occur during the construction of rural self-built houses (RSH) in China. Safety management tends to be overlooked due to the perceived simplicity of the construction process. Furthermore, it is essential to acknowledge that China currently lacks comprehensive laws and regulations governing safety management in RSH construction. This paper aims to analyze the behavior of key stakeholders (including households, workmen, rural village committee and the government) and propose recommendations to mitigate safety risks associated with RSH construction.Design/methodology/approachThis paper applies evolutionary game theory to analyze the symbiotic evolution among households, workmen and rural village committee, in situations with or without government participation. Additionally, numerical simulation is utilized to examine the outcomes of various strategies implemented by the government.FindingsWithout government participation, households, workmen, and rural village committee tend to prioritize maximizing apparent benefits, often overlooking the potential safety risks. Numerical simulations reveal that while government involvement can guide these parties towards safer decisions, achieving the desired outcomes necessitates the adoption of reasonable and effective strategies. Thus, the government needs to offer targeted subsidies to these stakeholders.Originality/valueConsidering that during the construction phase, stakeholders are the main administrators accountable for safety management. However, there exists insufficient research examining the impact of stakeholder behavior on RSH construction safety. This study aims to analyze the behavior of stakeholders about how to reduce the safety risks in building RSH. Thus, the authors intend to contribute to knowledge in this area by establishing evolutionary game model. Firstly, this study carried out a theoretical by using tripartite evolutionary game to reveal the reasons for the high safety risk during building RSH. Practically, this research points out the important role of households, workmen and rural village committee in improving safety management in rural areas. Besides, some suggestions are proposed to the government about how to reduce construction safety risks in rural areas.

The relationship between construction workers’ emotional intelligence and safety performance

PurposeConstruction enterprises are achieving the goal of production safety by increasingly focusing on the critical factor of “human” and the impact of individual characteristics on safety performance. Emotional intelligence is categorized into three models: skill-based, trait-based and emotional learning systems. However, the mechanism of action and the internal relationship between emotional intelligence and safety performance must be further studied. This study intends to examine the internal mechanism of emotional intelligence on safety performance in construction projects, which would contribute to the safety management of construction enterprises.Design/methodology/approachA structural equation model exploring the relationship between emotional intelligence and safety performance is developed, with political skill introduced as an independent dimension, situational awareness presented as a mediator, and management safety commitment introduced as a moderator. Data were collected by a random questionnaire and analyzed by SPSS 24.0 and AMOS 26.0. The structural equation model tested the mediation hypothesis, and the PROCESS macro program tested the moderated mediation hypothesis.FindingsThe results showed that construction workers' emotional intelligence directly correlates with safety performance, and situational awareness plays a mediating role in the relationship between emotional intelligence and the safety performance of construction workers. Management safety commitment weakens the positive predictive relationships between emotional intelligence and situational awareness and between emotional intelligence and safety performance.Originality/valueThis research reveals a possible impact of emotional intelligence on safety performance. Adding political skills to the skill-based model of emotional intelligence received a test pass. Political skill measures the sincere and cooperative skills of construction workers. Using people as a critical element plays a role in the benign mechanism of “Emotional Intelligence – Situational Awareness – Safety Performance.” Improving emotional intelligence skills through training, enhancing situational awareness, understanding, anticipation and coordination and activating management environment factors can improve safety performance. Construction enterprises should evaluate and train workers' emotional intelligence to improve workers' situational awareness and safety performance.

Establishment of Safety Management Measures for Major Construction Workers through the Association Rule Mining Analysis of the Data on Construction Accidents in Korea

Despite increasing industrial advancements, fatal and severe accidents, such as “Falls”, “Struck-by”, “Hit by an object”, “Be crushed”, and “Caught-in/between” accidents, persist in developed countries, including Korea. Various methods, including risk assessment, monitoring systems, technology improvements, and safety education, are being implemented to reduce accidents. However, only a few studies have revealed the causes of accidents and their interrelationships; these studies are based on limited data. Korea recently published accident data using national statistical systems, including the construction safety management integrated information (CSI), enabling the analyses of major accident types. Here, we selected various representative accident cases to minimize the duplication of the data published from 2019 to 2023 and applied the Material, Method, Machine, or Man (4M) analysis method, a risk assessment technique, to perform an accident-type-based association rule mining (ARM) analysis of the accident factors. Through the ARM analysis, we quantitatively identified complex correlations for major accidents. Based on the 4M factors derived through this analysis, we improved a 2–4 model for accident causation and proposed safety management measures for each construction entity.

Near-Miss Detection Metrics: An Approach to Enable Sensing Technologies for Proactive Construction Safety Management

One in every five occupational deaths occurs in the construction sector. A proactive approach for improving on-site safety is identifying and analyzing accident precursors, such as near-misses, that provide early warnings of accidents. Despite the importance of near-misses, they are frequently left unreported and unrecorded in the construction sector. The adoption of modern technologies can prevent accidents by automated data collection and analysis. This study aims to develop near-miss detection metrics to facilitate the automated detection of near-misses through sensors. The study adopted a mixed method approach including both qualitative and quantitative approaches. First, a quantifiable definition of near-misses was developed from the literature. Hazards, accidents, and the causes of accidents were identified. Through empirical and statistical analyses of accidents from the OSHA repository, combinations of unsafe acts and conditions responsible for a near-miss were identified. The identified factors were analyzed using a frequency analysis, correlation, and a lambda analysis. The results revealed twelve significant near-misses, such as A1—approach to restricted areas and C2—unguarded floor/roof openings, A5—equipment and tool inspection was incomplete and C8—unsafely positioned ladders and scaffolds, A2—no or improper use of PPE and C2—unguarded floor or roof openings, etc. Lastly, measurable data required by sensors for autonomous detection of near-misses were determined. The developed metric set the basis for automating near-miss reporting and documentation using modern sensing technology to improve construction safety. This study contributes to improving construction safety by addressing the underreporting of near-miss events. Overall, the developed metrics lay the groundwork for enhancing construction safety through automated near-miss reporting and documentation. Furthermore, it helps for the establishment of safety management schemes in the construction industry, specifically in identifying near-misses. This research offers valuable insight into developing guidelines for safety managers to improve near-miss reporting and detection on construction sites. In sum, the findings can be valuable for other industries also looking to establish or assess their own safety management systems.

A hybrid deep semantic mining method considering fuzzy expressions for the automatic recognition of construction safety hazard information

Safety hazards are a key consideration in construction management. The efficient recognition of safety hazard information can help managers formulate safety hazard management measures and improve the efficiency of construction safety management. However, construction site safety hazard data are stored in semistructured and unstructured text formats, which cannot be directly converted into understandable and usable information. Moreover, safety hazard text contains many fuzzy expressions, thereby increasing the difficulty of text semantic analysis; thus, how to accurately mine safety hazard information from complex and diverse text data is an urgent problem that must be solved. In consideration of this problem, we propose a bidirectional long short-term memory (BiLSTM) method with a fuzzy word vector and self-attention mechanism (FSABiLSTM) to automatically recognize safety hazard information. This method adopts TextRank and Word2vec to calculate the fuzzy word vector and process fuzzy expressions in safety hazard text. The safety hazard text semantic features are deeply extracted based on BiLSTM and a fuzzy word vector, and the extracted semantic features are analyzed via a self-attention mechanism. Actual construction safety hazard text is used to verify the reliability and applicability of the method, and the results indicate that the accuracy of this method, which outperforms existing machine learning methods, is 91.70%. In addition, the FSABiLSTM method can be used to automatically evaluate the risk degree of safety hazards; this use is beneficial to managing and controlling safety hazards. Concerning safety hazard text data, this study provides a new deep mining approach that can enhance safety management efficiency.

The construction industry faces safety management challenges that impact its reputation and workforce well-being. Despite existing safety regulations, safety violations persist, necessitating innovative solutions. This thesis explores the potential of Building Information Modeling (BIM) as a tool to improve safety practices throughout the project lifecycle. A literature review identifies key safety factors and BIM features, revealing their interconnections and potential for synergistic improvements. A questionnaire survey and semi-structured interviews with 55 construction professionals from diverse regions revealed that over 45% of respondents reported positive outcomes from BIM implementation in their projects. A comprehensive framework is developed to integrate BIM-based safety improvement strategies into various project phases, providing practical guidelines and recommendations for construction professionals to enhance safety practices effectively and efficiently. The research emphasizes the significance of BIM adoption in the construction industry, promoting better safety outcomes and elevating safety management practices. The proposed framework offers valuable insights for stakeholders, encouraging the widespread adoption of BIM technology and its seamless integration with safety practices for improved project safety and overall construction efficiency.

Perencanaan keselamatan, kontrol keselamatan dan kinerja keselamatan

Abstract: Despite the fact that lean construction (LC) has been shown to increase construction safety, little research has been done been carried out to investigate how LC technology can be applied to safety management. This the study aims to close this gap by developing a safety planning and control (SPC) process based on LC technology and evaluate it using a structural equation model. The process is based on the final planner system research framework (LPS) and consists of four sub-systems (ie, analysis layer, planning layer, control layer, and performance layer). Data was collected from 150 projects HSE employee at building construction in the Jakarta area. These findings will serve as a guide for construction stakeholders looking to improve efficiency safety management by incorporating some LC technology into the SPC process. And four subsystems work together to create a positive circulation system that aids long-term improvement construction safety management.

Head-Integrated Detecting Method for Workers under Complex Construction Scenarios

Real-time detection of workers is crucial in construction safety management. Deep learning-based detecting methods are valuable, but always challenged by the possibility of target missing or identity errors under complex scenarios. To address these limitations, previous research depended on re-training for new models or datasets, which are prohibitively time-consuming and incur high computing demands. However, we demonstrate that the better detecting model might not rely on more re-training of weights; instead, a training-free model can achieve even better performance by integrating head information. In this paper, a new head-detecting branch (55 MB) is added to the Keypoint Region-based Convolutional Network (Keypoint R-CNN, 226 MB) without altering its original weights, allowing for a less occluded head to aid in body detection. We also deployed motion information and anthropometric data through a post-processing module to calculate movement relationships. This study achieved an identity F1-score (IDF1) of 97.609%, recall (Rcll) of 98.173%, precision (Prcn) of 97.052%, and accuracy of 95.329% as a state-of-the-art (SOTA) method for worker detection. This exploration breaks the inertial attitudes of re-training dependency and accelerates the application of universal models, in addition to reducing the computational difficulty for most construction sites, especially in scenarios with an insufficient graphics processing unit (GPU). More importantly, this study can address occlusion challenges effectively in the worker detection field, making it of practical significance.

Integration of BIM data and real-time game engine applications: Case studies in construction safety management

Building Information Modeling (BIM) has unique features that improve safety management in construction by visually identifying potential risks. Integrating BIM with a real-time game engine is a cutting-edge idea for more effective safety management. This study aims to conduct two case studies by integrating BIM data with game engines from two aspects: 1) Construction Safety Training and 2) Pre-construction Safety Management. A framework that covers techniques for extraction of safety ideas, managing the game engine, and character modeling tools and resources is used to carry out the case studies. In the first case study, a construction site was created by Revit, and a real-life scaffolding failure accident was simulated by Unity to warn workers to prevent similar future events. The second case study was conducted on the procedure of evacuation modeling in an emergency, integrating a BIM model and Unity following distinct pathways. This evacuation modeling can be used as a training platform for the occupants to acquaint themselves with the inside facility, show directions of the shortest evacuation path from specific points, and provide necessary information on emergency equipment. Finally, the study explains how the integration of the BIM model and game engine applications can be applied for effective, straightforward, and helpful safety management with the most efficient BIM data transition.

Review - Construction Safety Management using Deep Learning and Computer Vision

Abstract: SafeZone is a deep learning and computer vision model that is aimed at improving the safety of construction workers and reducing potential hazards at construction sites. Three aspects are taken into consideration while designing the model – whether workers are wearing safety gear, potential accident zones at the site, and check for the quality of materials given to the workers. This project is intended to automate the task of identifying lack of safety and potential hazards at construction sites and subsequent implementation of safety measures to eliminate the chance of accidents. A vast majority of industrial work-sites are often never automated - and instead, manually supervised with minor application of object-based sensor technology. The project will attempt to bridge this gap with the help of Convolutional Neural Networks - which allows for a streamlined, utilitarian and flexible suite of tools that help supervisors and on-site working personnel in keeping their heads on a swivel.

Analisis Profil Kecelakaan Konstruksi pada Proyek Bangunan Gedung di Indonesia

The construction sector is the highest contributor to construction accidents, which is 31.9% of the total construction accidents. One of the leading causes of accidents is the need for more awareness from workers and companies of the importance of implementing OHS at work. This situation arises due to the need for maximum planning and implementation of the Construction Safety Management System through the Minister of Public Works and Public Housing, and the Indonesian government has issued Regulation Number 10 of 2021 concerning construction safety guidelines. Data collection in this study is secondary data, namely construction accident reports by the Construction Safety Committee. The analysis used is archival analysis, where the report is mapped to produce statistics on construction accidents based on the type of project, time of occurrence, day of occurrence, the impact of the accident, and the cause of the accident. The results showed that the building became the first rank of construction project types with a percentage of 35% where the occurrence was in the morning before noon, namely 08.00-12.00, and on Tuesday became a day that often occurred construction accidents based on the construction safety committee. It was found that the cause of the accident was dominated by human factors and work equipment, which would impact the damage to the building itself with a percentage of 56%. The results of this study will be helpful for implementers/construction accident experts as guidelines for the future

Exploration of Construction Safety Management of Civil Engineering Civil Construction Project

With the acceleration of urbanization, more and more construction projects are appearing, and the modern building functions are increasing, while the requirements for project management are also getting higher and higher. In the construction of civil engineering construction, it is necessary to make full preparations, rationally deploy materials, equipment and other resources to ensure the full implementation of construction technology, and further enhance the overall effect of engineering construction. The development of the market economy has promoted the reform of the enterprise management system and the bidding and tendering system. Many projects have made new adjustments in the reform system, leading to a new trend in the management mode of construction projects. It has made significant breakthroughs in management concepts, management strategies and management methods. The new model must bring changes in management. In view of this, this paper focuses on the related problems of civil engineering to improve the current management efficiency. If the quality of the project is not reasonably controlled, it will have a great impact on the economic benefits of the whole project and the development of the construction enterprise.

Implementation of Construction Safety Plan in The Building Project

Data on work accidents in the construction industry in Indonesia is still relatively high, so the government issued a Construction Safety Management System (CSMS) regulation in 2021. However, many middle to lower-class contractors still need help compiling it. Contractors still use job safety analysis as a substitute for the Construction Safety Plan (CSP) with minimal analysis. Therefore, it is necessary to research the preparation of CSP, which is integrated with the project technique method. The research method used is to describe CSP implementation in selected project cases. The study results show that contractors already have good resources and commitment to carrying out CSP but have limitations in understanding the techniques for preparing CSP documents accompanied by sound risk management analysis.
