2. The assertion and judgment

A. The Plaintiff’s summary of the Plaintiff’s assertion was directly paid KRW 130,790,00,000 for labor cost according to the agreement with the Defendant. The Plaintiff calculated the construction cost for the Defendant’s construction work. As such, the amount of KRW 691,716,50 for the materials, such as steel bars, ready-mixeds, and short heat, paid by the Plaintiff is KRW 372,00,000. The amount of the price for the materials paid by the Plaintiff exceeds KRW 319,62,626,50. Upon deducting the price for the above materials, the payment for the completed portion is KRW 319,716,506 (= KRW 691,716,506 – KRW 372,090,000). Accordingly, the amount of the payment for the completed portion is more than KRW 315,000,000 for the construction cost paid by the Plaintiff.

Therefore, 126,163,00 won remaining after deducting 4,626,506 won from 130,790,000 won directly paid by the Plaintiff constitutes an excessive construction cost.
