💡 A Word from JOBPLOY
Yoonsung Construction Co., Ltd. is a specialized company focusing on railway track and civil engineering construction, and work often takes place at public infrastructure sites. Since railway and civil engineering sites have very strict safety regulations and may involve night work or equipment cooperation, it is most important to strictly follow on-site safety rules and signaling systems. Learning basic construction safety Korean and technical terminology to clearly understand work drawings and instructions will be of great help in adapting to the site and performing job duties. JOBPLOY recommends this for your career.
