A. The Plaintiff asserted that the construction cost of the instant construction project provided by the Defendant was calculated as KRW 338,40,00,000, and the contract for the instant construction project was concluded through a tendering procedure with the construction cost of KRW 292,747,400, which is 86.5% of the said amount as the construction cost. The said design was excluded from some types of construction, such as the installation of a two lines necessary for performing the instant construction project, or the volume of other types of construction has been reduced. Thus, the Plaintiff had no choice but to increase the construction cost on a more inevitable basis than the reduced construction cost.
