A successful construction project hinges on the effective and efficient management of human resources. The stress of human resources is directly related with work performance, and as such, should be managed to improve work performance. This study aims to perform a comparative analysis of job stress levels after a survey on the job stress of field managers and workers. Through the analysis, it is found that the stress levels of field managers are different from those of the workers and construction field managers and workers get job stress scores less than average scores of Korean male workers. In addition, different personal factors affect the field managers and the workers differently. Therefore, understanding by which factor the other parties become stressed is expected to improve efficiency in the management of human resources.

The success of construction projects is heavily dependent on the work ability of the field managers who manage the execution of projects. The work ability of field managers is influenced by various elements such as job stress and individual characteristics. The purpose of this study is to reveal the factors influencing the work ability of construction field managers in Korea. Work ability is evaluated bases on the Work Ability Index(WAI) developed by the Finnish Institute of Occupational Health, while job stress is measured using the Korean Occupational Stress Questionnaire Short Form developed by the Korean Occupational Safety & Health Agency. The results showed that field managers under higher job stress have lower work abilities. In addition, it is revealed that exercise or religious practice have a positive influence on work ability. This study will help to increase the work ability and enable the efficient management of organization at building construction sites.
