B. The defendant's assertion 1) The defendant asserts that the plaintiff cannot respond to the plaintiff's claim for construction cost until the plaintiff completes the repair of defects, such as equal heat between the office building and the factory finishing party, and omission of the shock network of office windows.

B) The Defendant asserts to the effect that the Plaintiff cannot accept the Plaintiff’s claim for the construction cost until the payment of the security deposit for repairing defects under the instant contract is made. (2) The Defendant’s argument as to the Plaintiff’s claim is examined, and there is no evidence to acknowledge that there was any defect identical to the Defendant’s assertion on the newly constructed factory building. (b) The Defendant’s argument is without merit.) The Defendant agreed to pay or submit the security deposit for repairing defects of KRW 20,262,00 (=675,400,000 x 3%) in cash or letter of guarantee until the Plaintiff is paid the construction cost. Therefore, the Plaintiff’s obligation to pay the security deposit for repairing defects remains.
