Although nominated subcontractor system in which an employer nominates a specialist contractor is widely used all across the world, it does not exist in Korea as separated construction procurement system in which electrical works and communication works are separately nominated is widely used.
 The purpose of this study is to clarify the structure of separated construction procurement system and coordination problems that can arise through analysis of legislations related to separated construction procurement in Korea. As the result, this study elucidated that though Korea made it mandatory to separately employ electrical works and communication works to guarantee the quality of specialized works from 1970s, standards of related legal articles are different from one another. Second, the study made clear the principal agents of design work, supervision work and construction work. Lastly, study revealed the contradiction that while responsible supervision is conducted in the coordination regarding design work, supervision work and construction work for public works, general contractors conduct construction coordination in private works.
