People hear "riser management" and picture a telecom closet. On a campus, the riser leaves the building entirely. It runs under lawns and parking lots, through duct banks and handholes, between buildings that each assume someone else is watching it. That below-grade layer is where governance matters most, precisely because nobody can see it.
Underground systems are interconnected systems
Inside a building, infrastructure at least has an address. A riser room has a door you can control and walls you can point at. Underground, everything shares everything. One duct bank carries pathways for multiple buildings. One handhole sits in the path of every carrier feed on that side of campus. Amenity A/V, EV charging, irrigation controls, carrier laterals, and building networks all cross the same few trenches.
That interconnection cuts both ways. It is what makes a campus efficient, and it is what makes an undocumented change dangerous. A contractor who opens a handhole to fix one thing is standing on top of six other systems, none of which are labeled for his benefit. Nobody watches a lawn the way they watch a lobby. If the building side of the discipline is weak, the underground side is usually nonexistent: no records of what runs where, no control over who opens what, and no way to know a pathway was disturbed until something three buildings away stops working.
What governance looks like below grade
The discipline is the same one that governs a riser room, extended to spaces that happen to have sod on top:
- Document the pathways. Every duct bank, conduit, handhole, and vault, with what runs through it and who owns each cable. Field-verified, not inherited from decades-old drawings.
- Treat access points as controlled spaces. A manhole is a telecom room with a heavier door. Opening one is an access event that deserves a request, a purpose, and a record.
- Put excavation inside change management. Trenching, boring, and landscaping projects near documented pathways get reviewed before the shovel arrives, not after the cut.
- Keep records owner-controlled. Underground knowledge is the easiest to lose, because it walks away with whichever contractor buried it. The property must own the record.
Design-stage governance pays twice
On new campus work, the highest-return decision is invisible: engineering conduit capacity and documentation for phases that have not been built yet. Do it well and the next phase lights up without tearing up the ground a second time; every project after the first starts from a known map instead of exploratory digging. That is infrastructure governance in one sentence. You document what exists, you control how it changes, and future work gets faster and cheaper instead of starting from zero.
This is not theory for us. GDS engineered exactly this approach for a $40 million campus redevelopment in Carmel, Indiana, from the underground conduit network to a dedicated campus amenity network, and our Midwest operations center now sits on that campus. The full story is in the GDS Technology case studies.
Not just a campus problem
Single buildings have outside plant too. The entrance conduits under your sidewalk, the handhole at the curb, the carrier vault in the alley: they carry every service in your building through spaces you rarely think about. A 60,000-square-foot office has the same governance need as a twelve-building campus; the map is just shorter. If your infrastructure records stop at the property line, or at the closet door, an assessment will show you what is unaccounted for in between.
