Pre-Fabrication
One standard, many builders, built off-site.
Every board is pre-fabricated in the factory to a single non-proprietary Siemens standard, so appearance, layout and functionality stay consistent regardless of which JV manufacturer builds it. This multi-manufacturer production model lets large programs be distributed across the JV without stretching labour or blowing out delivery times, while off-site assembly removes work from the critical path and reduces on-site risk and time.
- Factory build to a single, non-proprietary Siemens standard
- Multi-manufacturer production model for consistency at scale
- Off-site assembly that reduces site risk and compresses program time
- Warehousing concept for the 5–10 most common board types
Manufacturing
Shared capacity, single standard, serious scale.
The JV draws on a 190+ workforce across four Victorian plants, enabling rapid scaling, workload balancing and resource sharing so no project stalls waiting on a single line. Every board is built on the Siemens SIVACON platform with SENTRON 3WA breakers, assembled from Australian BlueScope steel to the highest Australian standards. Backed by the JV’s combined 350 staff and $345m revenue, this model delivers rapid, consistent and repeatable output for stage-based data-centre programs where volume reliability matters.

By engineering, manufacturing, integrating and testing critical systems in a controlled factory environment, Q4 shifts complexity away from site and into production. This parallel approach allows manufacturing to progress alongside site preparation, reducing onsite labour and installation requirements while improving quality control, program certainty and speed to deployment. Standardised, repeatable architecture also provides greater predictability across multi-stage and multi-site data centre programs.
Built in Australia for Australian conditions, Q4’s prefabricated solutions are designed around scalability, rapid deployment, reliability and operational certainty. Capacity can be deployed when and where it is required, enabling operators to respond to changing technology and increasing compute demands without overbuilding infrastructure from day one. The result is a more agile pathway to critical capacity — engineered for today, and ready for tomorrow.
The joint venture has been expanded to include large scale capability in the building of prefabricated assemblies with existing relationships with Hamilton Marino and MAZ Group. Both builders provide design, manufacture and assembly of high end, technological and structurally compliant prefabricated switchrooms and skids specifically for the Australian datacentre market. Q4 work closely with the data centre owners to provide turn-key solutions to meet the clients specifications.
Backing Australian manufacturing and local supply
Q4 is committed to Australian manufacturing and local supply, keeping capability, jobs and quality control here in Australia. This commitment runs through our Q4 Power Distribution capability, where switchboards and assemblies are manufactured locally. By sourcing and building domestically, we deliver equipment our clients can trust — with the traceability and accountability that local manufacture provides
Prefabricated Assembly
One standard, many builders, built off-site.
With existing experience in building switchrooms within the group, Q4 have expanded the room capability to include two trusted builders, to provide the defined skillset and scale to manufacture high volume assemblies. Building switchrooms and skids to detailed specifications in controlled environments, provides untold benefits, including:
Procurement
Shared capacity, single standard, serious scale.
The Q4 team work closely with the design a turn-key solution to the complete switchroom and skid delivery. With ease of business in mind, Q4 provide flexibility and the client supplied free-issue- equipment to keep margin costs to a minimum and provide a cost-effective product for the data centre market. The Q4 team have existing relationships with all suppliers including:
