The Impact

Construction noise is an integral part of urban social noise. Construction workers are more directly and significantly affected by construction noise. Therefore, the construction noise situation within construction sites, the acoustic environment experience of construction workers, and the impact of noise on them are highly worthy of attention. This research conducted a 7-month noise level (LAeq) measurement on a construction site of a reinforced concrete structure high-rise residential building in northern China. The noise conditions within the site in different spatial areas and temporal stages was analyzed. Binaural recording of 10 typical construction noises, including earthwork machinery, concrete machinery, and hand-held machinery, were performed. The physical acoustics and psychoacoustic characteristics were analyzed with the aid of a sound quality analysis software. A total of 133 construction workers performing 12 types of tasks were asked about their subjective evaluation of the typical noises and given a survey on their noise experience on the construction site. This was done to explore the acoustic environment on the construction site, the environmental experience of construction workers, the impact of noise on hearing and on-site communications, and the corresponding influencing factors. This research showed that the noise situation on construction sites is not optimistic, and the construction workers have been affected to varying degrees in terms of psychological experience, hearing ability, and on-site communications. Partial correlation analysis showed that the construction workers’ perception of noise, their hearing, and their on-site communications were affected by the noise environment, which were correlated to varying degrees with the individual’s post-specific noise, demand for on-site communications, and age, respectively. Correlation analysis and cluster analysis both showed that the annoyance caused by typical construction noise was correlated to its physical and psychoacoustic characteristics. To maintain the physical and mental health of construction workers, there is a need to improve on the fronts of site management, noise reduction, equipment and facility optimization, and occupational protection.

Grey Correlation Analysis

This paper proposes an improved evaluation model combining grey correlation analysis and AHP method that measures the safety performance of construction site. The safety assessment index system was established relating the actual condition of construction site. The weight of each assessment index was calculated through AHP model which use in grey correlation analysis for breaking through the limitations of conventional method. Then, the grey correlation degree was obtained through calculating the weighted means of grey correlation coefficient, and then, the rank of safety performance level of construction sites was determined. Through this improvement, the assessment results can be more scientific and functional. The effectiveness of our methodology was verified with an empirical study. The results show that this method can be an effective tool to predict the safety performance of construction projects sites, which is useful to reduce the occurrence of the construction safety misadventure.

Mode Of Transmission

Construction sites generate high levels of dust typically from concrete, silica, asbestos, cement, wood, stone, and sand. Workers who are exposed to the said environment are faced with the risk of inhaling particulate materials that might lead to adverse respiratory problems. The lack of publication on the awareness of construction workers on the risk associated with silica dust exposure was the basis of the study. This study assessed the level of awareness of construction workers on the risk associated with silica dust exposure and the safety practices to minimize it. Purposive sampling was used in the selection of 65 respondents from different construction sites located in Baguio City, Philippines. A survey questionnaire containing four point Likert scales were used to determine the level of awareness on the health effects, mode of transmission, and sources of silica dust. The study further assessed the level of safety practices in mitigating the effects of silica dust exposure. The respondents were moderately aware (M=2.52) of the health effects, moderately aware (M=2.69) of the mode of transmission, and moderately aware (M=3.08) of the sources of silica dust. The results further showed that the respondents moderately practiced (M=2.84) activities to mitigate the health effects of silica dust exposure and moderately practiced (M=3.17) the use of personal protective equipment in the construction site. The results suggest that construction workers must be made more aware of the health effects of silica dust exposure and, mitigation activities and utilization of personal protective equipment must be strictly imposed in the construction site.

Recently, efforts to effectively reduce particulate matter by identifying its sources and trends have become necessary due to the sustained damage it has caused in East Asia. In the case of South Korea, damage due to fugitive dust generated at construction sites in densely populated downtown areas is significant, and particulate matter in such fugitive dust directly influences the health of nearby residents and construction workers. Accordingly, the purpose of the present study was to develop a method for calculating emission factors for PM10 and PM2.5 emission amounts in the fugitive dust generated in construction sites and to derive emission amount trends for major variables to predict the amounts of generated particulate matter. To this end, South Korean emission factors for PM10 and PM2.5 for different construction equipment and activities that generate fugitive dust were derived and a method for calculating the amount of particulate matter using the derived emission factors was proposed. In addition, the calculated total emissions using these factors were compared to those calculated using construction site fugitive dust equations developed for the United States, Europe, and South Korea, and the trend analysis of total emissions according to the major emission factor variables was conducted.

Ethnographic Fieldwork

Argentine enterprises subsume Paraguayan migrant workers into the construction industry in the Buenos Aires metropolitan area, subordinating them to the demands of production by temporarily housing them on the construction sites themselves. Ethnographic fieldwork carried out on various construction sites between 2006 and 2015 shows how this practice overlaps with wider processes of global transformation in labor relations. The lodging of workers on construction sites is an increasingly widespread strategy for capitalist entrepreneurs to exploit the migrant workforce even further. Las empresas argentinas han incorporado a los trabajadores migrantes paraguayos a la industria de la construcción en el área metropolitana de Buenos Aires y los han subordinado a las exigencias de la producción, alojándolos temporalmente en las obras mismas. Un trabajo de campo etnográfico realizado en varias obras entre 2006 y 2015 muestra cómo dicha práctica se entrelaza con procesos más amplios en la transformación de las relaciones laborales a nivel global. El alojamiento de los trabajadores en las obras es una estrategia cada vez más extendida para que los empresarios capitalistas puedan explotar la mano de obra migrante aún más de lo que ya hacen.

This paper proposes a hybrid evaluation approach combining fuzzy comprehensive assessment method and AHP that measures the safety performance of construction site. The weight of each index was calculated through AHP model which use in fuzzy comprehensive assessment, and then the safety level of construction sites was determined by multi-layer fuzzy comprehensive assessment technique. In order to find out the main causes of safety level of construction site’ changes, the grey correlation analysis was used to quantify the influence degree of each factor of safety level of construction site. The effectiveness of our methodology was verified with an empirical study by using the data of 3 construction sites we investigated. The results show that this approach can be an effective tool to predict the safety performance of construction projects sites, which is useful to provide a scientific basis for the management and decisions of accident prevention.

Construction Safety Management

Purpose The purpose of this paper is to improve the safety of construction workers by understanding their behaviors on construction sites using spatio-temporal (ST) trajectories. Design/methodology/approach A review of construction safety management literature and international occupational health and safety statistics shows that the major reasons for fatalities on construction sites are mobility-related issues, such as unsafe human behaviors, difficult site conditions, and workers falling from heights and striking against or being struck by moving objects. Consequently, literature has been reviewed to find possible technological solutions to track the mobility of construction workers to reduce fatalities. This examination has suggested that location acquisition systems, such as Global Positioning System (GPS), have been widely used for real-time monitoring and tracking of workers on construction sites for hazard prevention. However, the raw data captured from GPS devices are generally available as discrete points and do not hold enough information to understand the workers’ mobility. As a solution, an application to transform raw GPS data into ST trajectories using different preprocessing algorithms is proposed for enhancing worker safety on construction sites. Findings The proposed system preprocesses raw GPS data for stay point detection, trajectory segmentation and intersection of multiple trajectories to find significant places and movements of workers on a construction site to enhance the information available to H&S managers for decision-making processes. In addition, it reduces the size of trajectory data for future analyses. Originality/value Application of location acquisition systems for construction safety management is very well addressed in the existing literature. However, a significant gap has been found: the usage of preprocessed ST trajectories is still missing in workers’ safety monitoring scenarios in the area of construction management. To address this research gap, the proposed system uses preprocessed ST trajectories to monitor workers’ movements on a construction site to identify potentially unsafe behaviors.

Building Process

Construction site monitoring is currently performed through visual inspections and costly selective measurements. Due to the small overhead in construction projects, additional resources are scarce to frequently conduct a metric quality assessment of the constructed objects. However, contradictory, construction projects are characterised by high failure costs which are often caused by erroneously constructed structural objects. With the upcoming use of periodic remote sensing during the different phases of the building process, new possibilities arise to advance from a selective quality analysis to an in-depth assessment of the full construction site. In this work, a novel methodology is presented to rapidly evaluate a large number of built objects on a construction site. Given a point cloud and a set of as-design BIM elements, our method evaluates the deviations between both datasets and computes the positioning errors of each object. Unlike the current state of the art, our method computes the error vectors regardless of drift, noise, clutter and (geo)referencing errors, leading to a better detection rate. The main contributions are the efficient matching of both datasets, the drift invariant metric evaluation and the intuitive visualisation of the results. The proposed analysis facilitates the identification of construction errors early on in the process, hence significantly lowering the failure costs. The application is embedded in native BIM software and visualises the objects by a simple color code, providing an intuitive indicator for the positioning accuracy of the built objects.

In recent years, the number of foreign workers employed on construction sites in Korea has been on the rise, and industrial accidents involving foreign workers have become a social issue. Yet despite this fact, the interest in safety education for foreign workers has still been relatively low. For this reason, the purpose of this study is to analyze the current state of safety education for foreign construction workers. To conduct an analysis of the current status, we surveyed foreign construction workers currently working at construction sites. Based on the results of this survey, we have derived an outline for an improvement plan founded on an awareness of and problems in safety education for foreign workers.
