Every project to be carried out must be constituted by the memory which is formed by two clearly differentiated parts:
The descriptive memory or memory itself.
The annexes of the memory.
The description is an informative document that must contain the description and justification of the technical solutions adopted, with as many chapters and sections as divisions or subdivisions have been adopted for its realization. From the reading of the report, a clear idea of what the project represents must be clearly obtained without having to consult the remaining documents.
