Solution · Data centres & AI factories
Data centre & AI factory steel structures – built at the speed of compute
Long-span data halls, roof plant platforms, MEP support steel, generator and power yards – engineered for the loads of liquid-cooled AI racks, fabricated in parallel and delivered in sequence so your capacity comes online in months, not years.
- ~120 kW
- Per liquid-cooled AI rack many times a traditional IT rack
- > 1 t
- Per AI compute rack heavier floors, slabs and supports
- Parallel
- Fabrication & delivery frames, plant steel and MEP racks at once
- EXC3 · CC3
- Certified fabrication EN 1090-2 · AS/NZS 5131
Why AI changes the building
A data centre is a building wrapped around power and cooling. AI changes both: liquid-cooled GPU racks draw in the order of 120 kW each and weigh well over a tonne, coolant runs to every rack, and the heat-rejection plant on the roof or in the yard grows with every megawatt.
That puts more steel above the floor – heavier roof plant, dense racks of cable trays, busways and chilled-water pipes, platforms for generators, transformers and switchgear – and it puts the schedule under pressure. Steel is the material that keeps up: designed around the equipment loads, fabricated in parallel while the slab is poured, and erected bay by bay so fit-out can follow immediately.

Loads & performance
Designed around the equipment, not a rule of thumb
We take loads from the equipment schedule – chillers and dry coolers on the roof, hanging cable trays, busways and coolant pipes, and rack and CDU weights on the floor – and design frames, hangers and platforms for them, with deflection limits that protect containment, sprinklers and busway joints.
Where the owner requires a higher risk category or importance level, seismic restraint or vibration criteria, they are built into the design basis from the first approval drawing.
Speed
Parallel fabrication, sequenced delivery
Data centre programmes are measured in megawatts per month. Primary frames, roof plant steel, MEP racks and generator platforms are fabricated in parallel in our factory, trial-assembled where needed, and shipped in erection sequence – so the steel arrives in the order the crane needs it.
Approved standard details for hangers, racks and platforms are reused across halls and phases, cutting design and approval time for every phase after the first.
Roof & yard
Plant platforms that are safe to maintain
Chillers, dry coolers and generators need maintenance for decades. Our platforms come with grating floors, guardrails, toe boards, stairs and ladders detailed to the access standard of your market, and with dunnage designed so plant can be replaced without cutting steel.
Galvanising or a coating system for the exposure, and clear marking of every member, keep the plant steel serviceable for the life of the campus.

Preguntas frecuentes
What steel does a data centre need besides the building frame?
Roof plant and chiller platforms, MEP and cable tray support racks, generator skids and e-house platforms, pipe racks and bridges, stairs, ladders and walkways – often as much engineering effort as the main frame.
How do AI racks affect the structure?
Liquid-cooled AI racks are far heavier and more power-dense than traditional IT racks, and they bring coolant distribution and more heat-rejection plant. Floors, hanging MEP loads and roof plant all increase – we design to the equipment data in the owner's design basis.
Can you meet a fast-track programme?
Yes – frames, plant steel and MEP racks are fabricated in parallel and shipped in erection sequence, and standard details are reused across halls and phases.
Do you design for seismic regions?
Yes. Seismic design to AISC 341, AS 1170.4 or Eurocode 8 is included where the site and the owner's risk category require it, including restraint of MEP support steel.
Do you coordinate with MEP designers?
Yes. We work from a 3D structural model coordinated with MEP and architecture, so hangers, penetrations and platforms are agreed before approval.
