Honest scope
A target sector, described as one.
Where we are
Data centres are a sector JCGAU is building towards, not one in which the company holds a completed project record. What we bring today is comprehensive fitout, services coordination and commissioning discipline, which is directly applicable to comms rooms, edge and equipment facilities, and to the building works around critical infrastructure. Hyperscale construction is not within our current capacity and we would tell you so at the first conversation rather than at the tender interview.
We would rather set that out plainly on the page than have a buyer discover it during due diligence. It is also the honest reading of what a $20 million single-contract capacity means in a sector where individual facilities run to far more than that.
The constraint
In a critical facility the building is the smallest part of the cost.
Power, cooling, redundancy and the commissioning that proves them are the project. The structure is what holds them up.
A comms room or edge facility is a services problem with a building wrapped around it. The power path from the supply through switchgear, uninterruptible supply and distribution has to be designed for a redundancy topology, and the cooling has to be designed for a heat density that no ordinary commercial space produces.
Every one of those systems has to be proved to work, and proved to keep working when a component is taken out. That proof is a staged process that runs from the factory to a live load test, and it belongs in the programme as a work package with its own duration.
Redundancy
What you are buying when you buy resilience.
Redundancy is not a rating you select. It is a decision about how much of the system can be lost, or taken out for maintenance, while the load keeps running.
The three arrangements below cover most of what a small technical facility will consider. What separates them is not the number of components but whether the path is shared. A spare unit on a common board protects against a component failure and not against a board failure, which is the distinction that decides whether the room can be maintained without a shutdown.
Three redundancy topologies compared. Under N there is a single path from supply through switchboard and uninterruptible supply to the load, so any component failure takes the load down and maintenance requires a shutdown. Under N plus one there is a spare component on a shared path, so a single failure is survivable but the path itself is still common. Under 2N there are two entirely separate paths to a dual-corded load, so a whole path can be lost or maintained with the load still running. The cost rises with each step and so does what can be maintained without a shutdown.

Diagram of the staged commissioning process used on critical facilities: factory testing of equipment, site acceptance on delivery, component-level testing once installed, integrated systems testing across systems, and finally a load test that simulates real conditions and failure. Each stage has to pass before the next begins.

On a critical facility the building is not finished when it is built. It is finished when it has been proved, including proved to behave correctly when something fails. Commissioning is a work package, not a week at the end.
Where we add value now
The work we can genuinely do today.
- Comms rooms and equipment rooms
- Within commercial and industrial buildings. High-density cooling, dedicated power, containment, fire suppression interfaces and access control. A common requirement in every workplace and industrial project we deliver.
- Edge and small technical facilities
- Where the scale sits inside our capacity and the discipline required is services coordination and commissioning rather than hyperscale construction management.
- Shell, base build and enabling works
- Slab, structure, envelope, hardstand and site services around critical infrastructure, coordinated to a specialist fitout contractor’s requirements.
- Upgrades in operating facilities
- Works alongside live equipment, where isolation planning, permit discipline and communication with the operations team are the whole job.
- Client-side support
- Where a client is procuring a specialist and wants builder-grade estimating, buildability and programme interrogation on their side of the table.
A critical facility is not finished when it is built. It is finished when it has been proved.

Questions
Have you built a data centre?
Not under the JCGAU entity. We say so plainly. What we do hold is comprehensive fitout and services coordination capability that applies directly to comms rooms, equipment rooms and edge facilities, and we are open about the boundary.
Would you tender for a hyperscale facility?
No. It sits outside our current capacity, and taking it on would not serve you.
Can you build the base building for a specialist fitout contractor?
Yes. Shell, structure, envelope and site services coordinated to their requirements is work we are well suited to.
Can you build a comms room inside our office project?
Yes, and it is a normal inclusion in the workplace projects we deliver.
Other sectors
Ask us where the boundary is.
We will tell you which parts of a critical facilities project we are the right builder for, and which parts we are not.
