How does the law define project implementation for termination purposes?

The full explanation

For the purposes of applying termination rules, "Implementation" is legally defined as the developer taking possession of the construction site. Furthermore, it requires the commencement of construction works in accordance with the design plans that were approved by the Competent Entities. Levelling works and the completion of infrastructure are also deemed as the start of project implementation. These definitions prevent developers from claiming construction has started when only minimal or non-structural work has been performed on the land.
