The book "Public Works Execution Agreement" constitutes an article interpretation and case law of the Public Works Code. With Law 4412/2016, a comprehensive legislative framework is established for public contracts in general and not only for public works, as is the case after Law 4782/2021. The interpretation is based on existing case law, which is quoted with its most significant thoughts either intact or slightly altered, while in cases where there is no case law, the author's opinion is presented. The work is simple and easy to understand in its structure, use, and comprehension, and it serves as an effective aid in approaching and deepening the legislation of public works.
