Abstract
The real-time monitoring of particulate matter (PM) at construction sites is essential for the health of workers and nearby residents. Several sensor-based systems have been developed for real-time PM monitoring. However, because construction sites are complex and large, there are limitations in installation areas and system costs. However, to overcome such limitations, the possibility of estimating PM using only emission factors, without direct measurement, has been confirmed. Nevertheless, most studies to date have evaluated the impact of PM outside the construction site, and the potential to monitor PM inside construction sites is still unclear. To bridge these knowledge gaps, this study estimated the PM inside a construction site with the application of emission factors and compared the estimated PM with that measured by the sensor at three actual construction sites. The comparison results showed that the Pearson's correlation coefficients ranged between 0.516 and 0.882, which varied according to the different site conditions and equipment used, and all had a positive correlation. Thus, the possibility of real-time on-site PM monitoring using emission factors is confirmed. In addition, the deviation in the comparison results presents improvement opportunities for practical use. The proposed monitoring system will contribute to the construction industry by supporting sustainable and safe construction environments.
