The difference between an executive project and a legalization project is that an executive project for installations can be drawn up without the need to legalize the installation. This project serves for the promoter to have all the execution items listed and to be able to tender the work more easily.
The legalization project is intended exclusively to justify the regulations and provide the necessary information for the industry and the inspector to issue the favorable control report. When the promoter requests the executive and the installation also needs to be legalized, the project goes through the tendering phase and once the work is completed, it goes to the legalization phase.
In the legalization project, the execution items are not detailed in such detail.
