Edirisinghe, R and Gunathilake, L (2025) IoT-based smart vest for heat stress management in construction. International Journal of Construction Management, 25(16), pp. 2137-2149. ISSN 1562-3599

Abstract

Heat stress is a major challenge in construction, affecting workers' safety and productivity. However, existing systems often lack real-time monitoring capabilities, personalization features, and power efficiency, limiting their effectiveness. To overcome these limitations, this work presents an Internet of Things (IoT)-based smart vest, specifically designed for the construction sector. The experimental development of an IoT-based circuit followed rigorous circuit design guidelines and testing protocols. The components and sensors in the circuit were carefully designed, including IoT capabilities to cater for the construction sector's hostile work and environmental conditions. Workers' health status will be continuously monitored without disrupting regular work. The proposed system demonstrated strong performance, with an error range of −0.4 to 0.06 °C and continuous operation of data transmission. The developed IoT-based smart vest allows for seamless communication with cloud and local smart devices, enabling global access and effective real-time data visualization and warnings for workers and management. Temperature is used as the primary metric. Future research by the authors will incorporate heart rate variability, galvanic skin response, and humidity to enhance heat stress assessment. Sensor accuracy and reliability were validated with the potential for integration into construction safety protocols to enable a proactive response to heat stress management.

Descriptive scope: 3 PCT

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
