2.1 More accurate estimates of installation costs

Preparing the site installation is essential and must be carried out with the utmost care.

In fact, it conditions the entire future execution of the project, and is accompanied by not inconsiderable costs that can weigh heavily on the installation cost budget.

Preparing the site installation also takes a relatively long time, and the launch schedule must take this into account.
