It is used as a reference during exchanges. This clarity limits misunderstandings and reinforces the coherence of the project.

Difference with contract documents

It is important to distinguish between specifications and legal documents. Compromise, lease or authentic act legally bind the parties. The specifications are drawn up front. It prepares these documents without replacing them. This distinction avoids confusion and secures the real estate journey.
