Labor productivity at construction sites during the pandemic: Causes and solutions

Abstract

This study aims to identify and analyze the factors that affect labor productivity in construction projects in Vietnam, particularly in the context of the COVID-19 pandemic. A total of 220 survey forms were distributed to people with knowledge and experience in the construction field, of which 203 valid forms were used for analysis. The collected data included information on project level, function, task, total investment, working time, expertise, type of unit, and working position of participants. The results of the descriptive statistical analysis showed that factors related to project management and operations, human resources, epidemic prevention and safety, material supply chain, and support policies have a significant impact on labor productivity. Based on these results, the study proposed five key groups of solutions: (1) improving project management capacity, (2) maintaining and developing human resources, (3) ensuring safety and health at construction sites, (4) diversifying the supply chain, and (5) perfecting the State's support mechanisms and policies. The research results provide important scientific and practical foundations, enabling construction enterprises to effectively respond to the epidemic crisis and enhance labor productivity, while contributing to the orientation of further research on risk management and sustainable development in the construction industry.
