We had four candidate plots for an edge node and no way to compare them. The site matrix came back with power capacity, access roads, and distance to the trunk line side by side. The council stopped arguing about the land and started asking about the substation, which was the real constraint all along.

Our board wanted a redundant ring immediately. The capacity model showed we could serve the first three districts on a single path and leave empty ducts for the rest. Splitting it into phases kept the civil works budget within what we could actually operate.

The first dossier we submitted got sent back twice for missing servitude documents. The second version had the permits, the survey notes, and the phased budget in one place. Committee review took a single session.

What helped most was the assumptions note. Every figure in the model had a source or a flag saying it still needed field confirmation. Nobody had to guess which numbers were solid and which were placeholders.

We expected a vendor pitch and got a survey schedule instead. Equipment specs listed two compatible options per node with the trade-offs written out, so our procurement team could run its own comparison.

The phased schedule named the milestones that would trigger the next tranche of work. When adoption in the first segment ran slower than projected, we paused phase two without renegotiating the whole plan.
