2. The parties' assertion

A. Although the Plaintiff took the form of accepting a subcontract for the instant construction project from the Plaintiff Multiurfy, in fact the Plaintiff concluded the instant construction contract directly with the Defendant under the name of Multiurfy, and completed the instant building.

The construction cost under the instant construction contract was KRW 1.1 billion (excluding value-added tax), but the additional determined construction cost was additionally required for the construction cost during the construction project, and the total construction cost was KRW 1.29,984,00 (excluding value-added tax) agreed with the defendant as additional construction cost, and the additional construction cost was KRW 9,9840,000 (excluding value-added tax).

The Defendant’s frequent demand for change of design led to the period of completion of the instant construction until December 31, 2014. While the Plaintiff completed the instant building before the said period, the Plaintiff is limited to KRW 1,429,824,00, out of the total construction cost of KRW 129,984,00 (= KRW 129,984,000), the Plaintiff’s total construction cost of KRW 129,984,00,000.
