Accordingly, the Defendant is obligated to pay the Plaintiff KRW 62,002,595, excluding KRW 30,000,000, which was paid at KRW 92,604,670. Accordingly, the Defendant’s assertion that the Defendant did not provide detailed explanation about the modified design drawings, and the Defendant’s signing of the modified design drawings is merely limited to the purport that the Plaintiff changed the length to 1,700 meters, and since the Plaintiff voluntarily performed the construction work based on the modified design drawings, the construction cost should be based on the initial design drawings of the instant construction project.

B. Whether to consent to the modification of the design drawing, 1, 3, 5, and 2.
