2. On November 201, 201, the Plaintiff asserted that the contract amount of KRW 1.1 billion was entered into with Defendant A regarding the instant construction work. Defendant A demanded not only the instant construction work but also the purchase agency for the materials inside the postnatal care center and changed the contract amount to KRW 1.43 billion (including value-added tax).

Defendant A entered into a contract for the Plaintiff and the instant construction work with the amount of construction cost of KRW 880 million (including value-added tax) on the following grounds: (a) the Defendant would directly purchase the materials inside the postnatal care center and would have tried to reduce the scale of the construction due to lack of investment funds.

Since then, the Plaintiff’s content of the instant construction project has been modified and its scope has been expanded, and finally, on August 30, 2012, the construction amount of the instant construction project with Defendant B and the instant construction project shall be KRW 1 billion (value-added tax separate).
