One campus. Several tenants. Who owns the spare capacity?
The next tenant can expose a conflict that has been present since the master plan: available capacity, reserved capacity and capacity promised by a date are not the same thing.
INSIGHTS / CAPACITY & PHASING
A campus can have enough ultimate capacity and still be unable to honor its next commitment.
Capacity is a promise with a location, a service condition and a delivery date. Two tenants can appear to fit the master plan while relying on the same unbuilt upgrade or the same operating reserve. Phasing turns a static capacity total into a sequence of obligations.
The conflict to find early
Separate capacity that exists, capacity reserved for a tenant, operational reserve and capacity dependent on future works. Do not make a commercial commitment against a total that combines all four. A tenant’s ramp profile, redundancy requirement or cooling change can alter the allocation even if its headline IT load stays constant.
The expansion is also an operating decision
The next phase may need access through an occupied area, a connection to a live system or temporary use of a corridor reserved for operations. The design can be buildable while the construction sequence is unacceptable to the existing tenant. Ask what must be isolated, who can approve the change and which access remains available before releasing the package.
How we would address it
We would reconcile the tenant commitments with the current infrastructure record, identify competing dependencies and bring the owner explicit choices: allocate, resize, accelerate an upgrade or rephase a commitment. The appointed technical and operating teams establish safe change requirements. Sitebraid carries the agreed cross-campus actions through to accepted closure.
The result to require
The next phase should start with a capacity allocation that reconciles to physical assets, documented assumptions for future capacity and an approved interface with existing operations. Completion of one phase should update that record, not leave the next team to reconstruct it.

The next phase starts inside someone else’s operating environment.
A campus can have land and funding for expansion but no acceptable way to build it around its first tenant. Protect the next phase before the first one opens.
