Reliable Control Systems for Critical Infrastructure
SCADA, PLC, and OT platforms for water authorities, energy operators, councils, and industrial sites where downtime is not an option.
Engineering standards we hold ourselves to
Twelve disciplines. One accountable delivery team.
Most projects fail at the handover between disciplines — the electrical designer who never sees the PLC code, the integrator who leaves before commissioning. We keep it under one roof.
SCADA Systems
Plant and network-wide supervisory control built for the alarm philosophy your operators actually need.
PLC Programming
Structured, documented logic across Rockwell, Siemens, Beckhoff, and CODESYS runtimes.
HMI Development
ISA-101 informed operator screens designed to reduce alarm fatigue, not add to it.
RTU Integration
Remote terminal unit deployment for sites with intermittent power and connectivity.
Telemetry Systems
Wide-area monitoring for assets spread across hundreds of kilometres of network.
OT Cybersecurity
IEC 62443-aligned network segmentation, hardening, and monitoring for control networks.
MES Solutions
Production tracking, traceability, and OEE reporting connected directly to the plant floor.
Cloud Integration
Historian and edge-to-cloud pipelines that don't compromise the control network's isolation.
Infrastructure that Australia doesn't get to switch off.
Every sector we work in shares the same constraint: the system has to keep running while you upgrade it.
Renewable Energy
BESS, wind, and solar plant control systems.
Utilities
Zone substations and distribution automation.
Water & Wastewater
Treatment plant and network-wide telemetry.
Local Government
Stormwater, flood, and civil asset monitoring.
Mining
Process control, MES, and safety interlocks.
Manufacturing
Line control, PLC and HMI modernisation.
Food & Beverage
Batch control, traceability, and MES.
Transport Infrastructure
Tunnel, rail, and ITS control systems.
Platform-agnostic by design.
We don't sell you a platform we happen to be certified in. We select the runtime that matches your risk profile, lifecycle, and existing asset base.
Ignition
Unlimited licensing, web-native deployment, and a fast path from SCADA to MES on one platform.
Siemens
TIA Portal, S7-1500 controllers, and WinCC for plants standardised on the Siemens ecosystem.
Rockwell Automation
Studio 5000, ControlLogix, and PlantPAx for process plants that live on the Rockwell stack.
Beckhoff
TwinCAT and EtherCAT for high-speed, deterministic machine control on standard PC hardware.
CODESYS
Vendor-independent IEC 61131-3 engineering for OEM and multi-vendor machine fleets.
Not sure which fits?
We audit the existing asset base before recommending a platform — not the other way around.
The same five stages, every project, no shortcuts.
Assessment & Scoping
Site audit, existing asset review, risk register, and a scope of work that names every I/O point before a line of code is written.
Design
Electrical drawings, control philosophy, network architecture, and a documented I/O schedule reviewed with your operations team before build.
Build & Configuration
PLC logic, HMI screens, and SCADA configuration built and factory-tested against the design before it reaches site.
Commissioning
Staged cutover, loop testing, and operator sign-off — planned around your outage windows, not ours.
Handover & Support
As-built documentation, operator training, and a support agreement that doesn't expire when the invoice is paid.
Three projects, three sectors, the same standard.
Regional Telemetry Network Modernisation
214 remote sites migrated from a 20-year-old RTU network to Ignition-based telemetry.
Grid-Scale Battery Storage Control System
Siemens-based control and protection integration for a 100MW/200MWh BESS in regional NSW.
Road Tunnel Ventilation & SCADA Upgrade
Rockwell PlantPAx and OT hardening for a live tunnel operating 24/7 throughout the works.
Four things every client tells us mattered most.
Not marketing pillars — the reasons clients give when they're asked why they came back for the next project.
Precision Engineering
Every I/O point documented, every control loop tested against a written philosophy — not tribal knowledge in someone's head.
Total Visibility
Your operators see what's actually happening in the plant, in real time, from wherever they're standing.
Infrastructure-Grade Resilience
Redundancy and cybersecurity built in from the design stage, not bolted on after an audit finding.
Full Lifecycle Ownership
One team from electrical design through to commissioning and support — one number to call when something needs attention.
"I've spent 12 years as a senior controls engineer across renewable energy, utilities, manufacturing, and large-scale SCADA work — usually called in when a live plant needed to change, upgrade, or migrate without stopping production. UHD Controls is that same standard, run as its own practice: one accountable engineer on your project, not a name added to a subcontractor list."
UHD Controls is a new company. The experience isn't.
These numbers reflect the founder's career to date, carried into this practice — not a client track record we're claiming after a few months in business.
