1. The parties' assertion

A. The Plaintiff’s assertion entered into a contract with Defendant B to contract the construction work of the Plaintiff’s Logistics Center (hereinafter “instant construction work”) at KRW 495,00,00 (including value added tax) for the construction work price of the Plaintiff at KRW 495,00,00,00 (including value added tax). Defendant B did not have a comprehensive construction license and entered into a contract with Defendant B as a contracting party to a contract for the instant construction work. Although the Plaintiff paid KRW 51,060,000 in excess of the agreed construction cost due to delay of construction, the Defendants demanded the Plaintiff to pay the construction cost, and thus the Defendants demanded confirmation of the absence of the obligation to pay the construction cost of the instant construction.

B. As to the instant construction project, the Plaintiff’s assertion by the Defendants entered into a contract with the Defendant Company for the construction cost of KRW 330,000,000, and paid only KRW 230,000 out of the said construction cost to the Defendant Company. Defendant B, in accordance with the agreement with the Plaintiff, paid only KRW 363,00,000 in relation to the instant construction project. The Plaintiff paid only KRW 280,000 out of the said cost to the Defendant Company B. As such, the Plaintiff is obligated to pay the unpaid construction cost of KRW 100,000, KRW 83,000,000 to the Defendant Company, and each delay damages therefrom.
