Evaluating the feasibility of smartwatches for allocating workers' time into workspaces on jobsites

Traditional data collection methods for progress and productivity monitoring on construction sites have mostly remained manual, involving verbal communication, routine job site walking rounds, and techniques such as work sampling (WS) studies.Such methods are costly and timeconsuming for construction companies.This study investigates the viability of employing smartwatches to monitor and allocate workers on construction sites, focusing on understanding productivity bottlenecks.Conducted through a case study in Fredericia, Denmark, the research highlights the potential of smartwatches in capturing real-time data on workers' activities and spatial distribution.It emphasizes the efficacy of this technology in enhancing data collection to comprehend factors influencing productivity.The findings underscore the significance of rigorous data collection, cleaning, and processing protocols to ensure the accuracy and reliability of the collected data sets.Overall, the study advocates the integration of wearable sensors, particularly smartwatches, as a promising avenue for improving productivity monitoring and management in construction projects.
