A comprehensive electrical solution for a high-performance, Green Star industrial development was the brief given to DGE for PFI’s Stage 3 development at Springs Road.
Partnering with Haydn & Rollett Construction, sustainability, performance and future scalability were front of mind for this site.
A key component of the project was the design and installation of a new high-voltage network and transformer infrastructure to power two buildings from a single source. As a result the site required a robust electrical backbone capable of supporting heavy manufacturing equipment, solar integration, and long-term operational demands.
With sustainability, performance, and future scalability front of mind, the site required a robust electrical backbone capable of supporting heavy manufacturing equipment, solar integration, and long-term operational demands.
The Challenge
Powering Two Buildings from One Transformer
The most technically demanding aspect of the project was the design and build of the high-voltage system engineered to power performance at scale. DGE took ownership of the design and build which included:
• Installation of a new 1000kVA transformer
• Integrating the transformer into an existing on-site high-voltage network
• Supplying power to two separate buildings from a single transformer
• Installing dedicated circuit breakers for each building within the transformer
Running two main switchboards back to a single transformer required significant coordination and extensive cabling infrastructure. While not standard practice across development projects, this engineered solution ensured efficiency, cost-effectiveness, and long-term flexibility for the site.
Low-Level Cable Tray Installation
MiTek’s specialised machinery required cable trays to be installed at approximately six metres high, significantly lower than typical warehouse tray installations.
With roof structures extending much higher, DGE engineered:
• Custom hanging systems
• Extended seismic bracing solutions
• Structural coordination to ensure compliance with seismic requirements
All seismic restraints were designed and delivered in-house, ensuring the installation would perform safely during an earthquake while protecting the infrastructure and machinery below.
Tight Programme & Coordination
The project was delivered within a compressed timeframe and required close coordination with:
• Main contractor (Haydn & Rollett)
• Green Star compliance requirements
• Solar installation integration
• Multiple trades operating simultaneously onsite
Early planning and proactive communication were critical to maintaining programme certainty.
Our Solution
DGE is always looking for smarter, more efficient ways to improve outcomes and this project was no different.
They delivered an integrated electrical package, combining high-voltage expertise with full building fit-out capability
High Voltage – Design & Build
• Designed the HV infrastructure in-house
• Installed and commissioned a 1000kVA transformer
• Connected to the existing site HV network
• Installed protection systems and building-specific breakers
• Ensured safe, compliant commissioning
Running two buildings from a single transformer required careful engineering and coordination, but the result was an efficient, scalable solution tailored specifically to the site’s needs.
Proactive Programme Management
Timelines were tight, and transformer lead times can often be a critical risk on projects of this scale.
To ensure the programme remained on track, DGE:
• Procured the transformer early to avoid supply delays
• Maintained clear, consistent communication with the main contractor
• Coordinated works to align with other trades
• Planned staging works to allow early commissioning of the building
Always looking for a better way, DGE poured a dedicated slab early for the main switchboard installation. This enabled the switchboard to be positioned and power brought on sooner than would typically be possible, supporting programme milestones and giving other trades access to temporary and permanent power earlier in the build.
This forward-thinking approach ensured smooth delivery despite the tight timeframe.
Full Electrical Fit-Out
• Main switchboard installations
• Distribution throughout both buildings
• Machine power supplies tailored to MiTek’s operational needs
• Data infrastructure
• Solar system integration
• Green Star-aligned installation practices
Sustainability & Green Star
In line with PFI’s development standards, the project was delivered to Green Star requirements, including:
• Solar panel systems installed on both buildings
• Energy-conscious electrical design
• Compliance with sustainability-driven specifications
Working as One Team
This project reflects DGE’s full-service capability in action.
Rather than separating high-voltage, fit-out, and compliance into multiple contractors, DGE provided a unified solution:
Design. Build. Deliver.
This reduced coordination risk, streamlined communication, and ensured accountability across the entire electrical scope.
The Outcome
Despite a tight timeframe and the technical complexity of delivering high-voltage infrastructure to power two buildings from a single transformer, DGE delivered a seamless result.
• Early commissioning was achieved through strategic planning and the early installation of the switchboard slab
• Transformer procured ahead of schedule, eliminating supply-chain risk
• Fully commissioned 1000kVA high-voltage infrastructure
• Efficient dual-building power solution designed for long-term scalability
• Solar-integrated, Green Star–aligned facility
• Delivered safely, compliantly, and within programme
By proactively pouring the switchboard slab and securing the transformer early, DGE removed two of the biggest potential programme risks before they became problems. This enabled earlier access to power for follow-on trades and supported construction momentum across the site.
Clear communication with Haydn & Rollett and disciplined coordination across trades ensured the project moved forward without disruption.
The result is a future-ready industrial facility with a robust electrical backbone, designed not just to meet today’s operational requirements, but to support MiTek’s growth for years to come.
One team. One solution. Delivered with confidence.
