“…For instance, Ali et al [45] proposed a project management approach to identify the cost overruns associated with waste components. In a similar vein, Rivera et al [46] conducted a study on 25 non-value-adding structural engineering companies (SECs) in Chile to identify waste and suggest productivity strategies for improvement. This study aims to explore the categorization of sub-activities further using the variables VA, ENVA, and NVA.…”

Construction is a crucial industry that drives a nation's economic growth, yet it often faces inherent challenges related to productivity and waste generation. Lean Construction (LC) has emerged as a promising approach to address these challenges. However, despite its success in various construction projects, some gaps in the practical adoption of LC hinder its widespread practitioner uptake. Therefore, to close the gap, the objective of this study is threefold: identify waste factors of construction activities, determine suitable lean tools for project performance improvement, and assess the impacts of the implementation of lean tools on project completion time and costs. A toll road project in Indonesia was investigated as the case study. A combined research method was employed by administering a questionnaire survey to pertinent project participants, conducting in-depth interviews, and analyzing relevant documents to achieve these objectives. This study discovered 15 non-value-added (NVA) activities that can be eliminated to enhance overall project performance. Most of these activities can be accommodated using coordination and collaboration, while some require a more comprehensive approach, including standardization, the Five S, crash programs, and overlapping techniques. Implementing lean tools resulted in a 19.17% reduction in project completion time, although it contributed to a 5.33% decrease in organizational profit compared to traditional approaches. The findings of this study hold the potential to benefit those facing similar issues, not only in emerging countries but also in developed economies grappling with similar contexts.

“…Architecture, engineering, and construction industry projects consider a series of stages, where different professionals and work teams interact at other time stages. This process is characterized by strong fragmentation, communication difficulties, and integration problems throughout the projects [1]. Geotechnical inspections and works are key in the early stages of projects in the construction sector.…”

Virtual Reality Training for Occupational Risk Prevention: Application Case in Geotechnical Drilling Works

The construction industry is considered one of the most dangerous industries globally. The construction site is a complex environment where diverse teams of people interact with large machinery. In addition, the lack of safety culture on the job site and deficiencies in safety training increase these problems. Within the construction works, geotechnical drilling worksites involve high-powered machinery, and workers are exposed to different risks when using them. Despite these risks, safety training courses on these topics are not specialized. Most of the training courses are generic in occupational hazards, failing to address in detail the work dynamics and risks associated with geotechnical work, where heavy machinery is a fundamental factor. There is a lack of adequate learning content specific to drilling works, meaning the heavy machinery, how to use it and how to prevent accidents due to these drilling tasks are poorly understood. This research investigates the risks associated with geotechnical drilling work and explores the potential of virtual reality (VR) to simulate immersive work environments, focusing on interaction with drilling machinery. A geotechnical drilling machine modelled 3D and integrated into a realistic VR environment. The machinery motions and the different tasks of the work team were modelled. The simulation allows a worker to interact in a working environment, identify risks and prevent accidents, and, moreover, be trained in best practices for machinery usage, according to previous real-world experiences from senior workers.

“…Indeed, the construction industry is simultaneously dynamic and vulnerable, and highly affected by environmental and geographical factors [ 16 , 17 ]. Nevertheless, the interaction between professionals from different disciplines, companies, and countries generates a heterogeneous environment affecting accident rates [ 18 , 19 , 20 ]. Moreover, indicators such as working with heavy equipment, working at heights, falling objects, noise, and vibrations act cumulative to the increase of frequency and severity of accidents on construction sites [ 17 , 21 ].…”

Occupational injuries are one of the main causes of Emergency Department visits and represent a substantial source of disability or even death. However, the published studies and reports on construction–occupational accidents in Switzerland are limited. We aimed to investigate the epidemiology of fatal and non-fatal injuries among construction workers older than 16 years of age over a 5-year period. Data were gathered from the emergency department (ED) of Bern University Hospital. A retrospective design was chosen to allow analysis of changes in construction accidents between 2016–2020. A total of 397 patients were enrolled. Compared to studies in other countries, we also showed that the upper extremity and falling from height is the most common injured body part and mechanism of injury. Furthermore, we were able to show that the most common age group representing was 26–35 years and the second common body part injured was the head, which is a difference from studies in other countries. Wound lacerations were the most common type of injury, followed by joint distortions. By stratifying according to the season, occupational injuries among construction workers were found to be significant higher during summer and autumn. As work-related injuries among construction workers are becoming more common, prevention strategies and safety instructions must be optimized.
