On March 201, Plaintiff C awarded a contract to E for the construction of new housing units on the ground of Seosan City, Seosan-si, and E subcontracted the construction of temporary materials, wood construction, and reinforced concrete construction among the construction of new housing units to the Defendant. However, the Defendant again subcontracted the wooden construction to F, and the Defendant re-subcontracted the reinforced concrete construction to the Plaintiff.

Therefore, since the Plaintiff completed reinforced concrete construction from April 23, 201 to May 28, 2011, the Defendant is obligated to pay KRW 14.7 million, which the Plaintiff did not receive, out of the agreed construction cost.

B. Since the Defendant’s reinforced concrete construction work built by the Plaintiff was subcontracted to F, the Defendant did not have any obligation to pay the construction cost to the Plaintiff.
