[Ground of recognition] Facts without dispute, entry of evidence Nos. 1 and 4, purport of the whole pleadings

2. The Plaintiff asserted that the construction was completed under the instant construction contract. The Plaintiff sought payment for the accounts payable for the construction cost from November 2012 to April 2013, and payment for the oil price and the total sum paid by the Plaintiff on behalf of the Defendant, KRW 85,622,48, and damages for delay.

On July 29, 2014, the Defendant settled with the Plaintiff on July 29, 2014 after the annual test. Since the design price of the instant construction works has been partially changed and the total construction price has been reduced by using heavy equipment, not human resources, the Defendant still remains 72,934,00,00, which deducts the total of KRW 121,740,343 of the construction cost first demanded by the Plaintiff from the annual test cost of KRW 115,885,27 of the reduced construction cost to be returned to the Defendant by the Plaintiff, and the total of KRW 6,580,000 of the annual test cost paid by the Defendant on behalf of the Plaintiff, 122,465,27.
