Comprehensive Analysis of Physical and Mental Workloads for Electronic Installation Workers Utilizing CVL and NASA-TLX at the Building X Construction

This research represents a crucial advancement in enhancing workplace safety within the construction sector.It investigates the evaluation of both physical and mental workloads among workers involved in electronic installations at the Building X construction site.The objective of the study was to evaluate physical workload using the Cardiovascular Load (CVL) method and to assess mental workload through interviews, along with the distribution of the National Aeronautics and Space Administration-Task Load Index (NASA-TLX) questionnaires.The findings show that ten employees aged between 21 and 45 recorded a %CVL value of under 30%, suggesting they did not encounter significant physical workload in their tasks.Nevertheless, the assessment of mental workload indicated that three employees faced a very high mental demand.According to the comparative analysis of the NASA-TLX categories, the effort is the most prominent factor, which underscores the necessity for intense focus and the capacity to meet established goals within this position.The primary three elements affecting mental workload are fatigue/saturation, the work environment, and air dust pollution.Recommendations for alleviating workload should be adhered to by referencing the Hierarchy of Risk Control in Occupational Safety and Health, in accordance with ISO 45001.
