Monitoring of air quality and meteorological parameters on the construction site

Abstract

The construction industry is one of the main producers of dust, greenhouse gases and air pollutants. Effective
operation and management of construction site operations can significantly reduce the project’s carbon footprint and other
environmental impacts. Through the cooperation of scientific and research institution and construction company, real-time
monitoring of air quality at the construction site was implemented using IoT technologies. An IoT-based system framework that
integrates a distributed sensor network to collect real-time data and demonstrate air quality at a construction site was implemented.
Different types of sensors were used to collect data related to NO2 and PM2.5, PM10 particles, as well as meteorological
parameters – wind speed and direction, humidity, pressure and temperature. The results of real-time measurements provide a
picture of the state of air pollution at the construction site and the connection with construction activities that can be managed in
order to reduce the concentration of polluting gases and suspended particles. Through on-site monitoring of construction site in Belgrade City, this study found that the dust level of construction activities is relatively high. Comparing the wind direction and PM concentrations, it can be concluded that the construction activity had a significant impact on the air quality around the construction surrounding areas. Regarding the main factors affecting the building construction dust emission, the correlations show that building construction dust emission was not significantly correlated with meteorological factors.
