나. 피고의 주장에 관한 판단 ⑴ 미시공 공사대금 공제 주장 ㈎ 피고는, 원고가 이 사건 공사 중 1층 기초 부분 보강공사, 계단실 기둥 2개 RC 보강공사와 4층 보 2개 RC 보강공사를 하지 않아 피고가 직접 15,694,000원의 비용을 들여 공사 마무리를 하였으므로, 위 금액은 피고가 지급하여야 할 공사대금에서 공제하여야 한다고 주장한다.

㈏ 살피건대, 을 제1, 2, 3호증의 각 기재만으로는 피고가 주장하는 위 미시공 공사 부분이 원고와 피고 사이의 이 사건 공사계약에 따른 공사 범위에 속한다고 인정하기에 부족하고, 달리 이를 인정할 만한 증거가 없다.
