公共工程契約，一般而言，大都定性在承攬契約，有債務不履行之適用。本文所論述，係對於公共工程契約損害賠償的方式，有不同的請求權基礎，再輔以其他國家之法令及實務，對於我國公共工程契約損害賠償之多元化，不再以狹義之承攬契約做為唯一討論之依據。並且對於賠償的方法及範圍，本文亦有詳細之論述，因公共工程之複雜程度，比起一般契約還要廣泛許多，常發生逾期完工、情事變更、品質不良及是否應依物價調整之爭議，攸關當事人權利義務，要如何界定其合理範圍及損害賠償，亦為難事，而為本文探討之重點。本文首先論述公共工程契約的特色，再剖析損害賠償的責任成立，其次探討責任範圍及損害賠償計算問題；並且對因果關係及違約金也加以討論；文末則對公共工程契約的風險合理分配及違約損害賠償責任提出本文觀點及建議供法學界、工程界及政府採購機關參考，使工程實務與民法債務不履行之損害賠償理論結合。

Public construction contract damages, in general, mostly are applied interpretation of the contract of hire of works, there is still breach of contract. The basis of a different right to request of breach of contract are discussed in this article and supplemented by the insights of other countries.

This paper first discusses the characteristics of public construction contract and the responsibility for damages established, and secondly to explore the scope of responsibility and damages calculation; discussed causation and penalties. The end of this paper suggested rational allocation of risks and damages for breach to public construction contract to put forward ideas for jurisprudence, engineering sector, and government procurement authorities.
