建築受給人의 瑕疵擔保責任에 있어서 約定違反의 瑕疵

Abstract

For the nature of the liability being not defiend, many conflicts with a contractors liability on a defective work may arise in construction Works. Specially, the problem of the liability by reason of breach of contract or warranty is concurrent with the general non-performance liability or related with the problem of defect of sales. But this problem is based on the concept of ‘Defects’. This study concentrates upon the concept of defects, especially of independent contractor's works. When tries to observe comparison method-the study of Japan and French-about this problem, the breach of contract is included in the concept of Defects of independent contractor's works. Following the above observations, this study tries to make clear the possible standards of defective works. Historically traced, the understanding of the concepts has changed so much during a very long period, the breach of agreements Current defect liabilities have their roots in another Roman institution established and developed by official market regulators in the area of sale law. This study makes conclusion like this. I think that contractors' defect liabilities could be included the defect of independent contractor' liability. When there are promises, like as some kind of contents the both parties agree or the special quality which is guaranteed by independent contractor and the breach of above contract or promise, the contractor is liable to this breach of contract. Following this conclusion, Firstly, the party providing work has control over the performance process, but only has to use control for the other party's sake. Secondly, the objects of the work contract has been continuously spread all through the time. A defective work can be defined as failure of the work to meet the quality or quantity requirements expressed in or implied by the contract. Thus for the decision whether the defects exist in the that work offered by independent contractor, it need to be considered two steps of judgments whether the evident promise or warranty by contractor exist and if exist, whether the independent contractor can be liable to the breach of promise or warranty. That is to say, to each of them apply general theories of agreement interpretation. Looking ahead, in interpreting, an important role might be played by the specified documents expressively or impliedly reported or offered by both parties and supposed by the owner in the project contract.
