2. Determination

A. As to the claim for construction price for B-related construction works, the Plaintiff asserted that: (a) while performing the relevant construction works, the Plaintiff was not paid the remainder of KRW 6,645,00,000 among the total construction cost of KRW 24,579,00,000, despite the completion of all of the construction works on December 2, 2013, while performing both underground parking lot painting construction, interior interior interior interior interior interior painting of second-class performance halls; and (b) galloning construction works.

However, in order to recognize the obligation to pay the additional construction cost to the contractor, there is a separate agreement between the contractor and the contractor on the execution of the additional construction and the payment of the additional construction cost. The written evidence Nos. 1 through 4, and No. 6 alone is insufficient to recognize that there is a separate agreement to implement the additional construction work and to receive the additional construction cost exceeding KRW 17,934,00, which is the construction cost paid by the Plaintiff and the Defendant between the Plaintiff and the Defendant. This part of the construction cost is due to domestic affairs.
