According to the evidence evidence Nos. 1, 1, and 13 of the instant construction contract, Article 13 and 14 of the General Conditions of the instant construction contract provide that the Plaintiff, the contractor, is obligated to subscribe to industrial accident insurance and employment insurance. The Defendant can recognize the fact that the Defendant paid the total amount of KRW 1,527,160 with the industrial accident insurance premium, KRW 1,527,160 with the employment insurance premium, KRW 5,575,640 with the industrial accident insurance premium, and thus, the Defendant’s above assertion has merit.

The plaintiff asserted that since the defendant agreed to pay the industrial accident insurance premium and the employment insurance premium at the time of implementing the construction contract of this case, the above insurance premium paid by the defendant should not be deducted from the construction cost, but the plaintiff's assertion is not accepted since there is no evidence to acknowledge the above assertion
