Engineers first. Everything else follows from that.
UHD Controls is a Melbourne-based industrial automation specialist — built to give infrastructure operators a single, accountable partner for SCADA, PLC, and OT engineering — from first site audit through to long-term support.
The gap between the drawing and the plant floor
Most control system problems aren't caused by bad hardware. They're caused by a handover gap — the electrical designer who never spoke to the person writing the PLC logic, the integrator who left site the day after commissioning, the documentation that described the system as it was designed rather than as it was actually built.
UHD Controls was set up to close that gap. We hold electrical design, controls engineering, commissioning, and documentation under one team, so the person who designs the system is accountable for how it runs three years later — not just how it looks in the proposal.
Four commitments that shape every project
We document everything as we build it
As-built drawings, tag lists, and network diagrams are updated at each stage — not reconstructed from memory at handover.
We scope before we quote
A site audit and I/O count come before a price. We don't estimate off a floor plan and a phone call.
We plan cutovers around your outage windows
Commissioning is scheduled to your operational constraints, with a rollback plan for every staged cutover.
We stay accountable after handover
Support arrangements are scoped at project start, not negotiated after something breaks.
A small team of senior engineers, not a bench of juniors
Every project is led by an engineer who has done the specific type of work before — not a project manager relaying instructions to a subcontractor.
Controls Engineering
PLC, HMI, and SCADA design and configuration across all five platforms we support.
Electrical Design
Switchboard, panel, and network design to AS/NZS 61439 and AS/NZS 3000.
OT Cybersecurity
Network segmentation, hardening, and monitoring aligned to IEC 62443.
Commissioning & Field
Loop testing, cutover management, and operator training on site.
What we hold ourselves accountable to
AS/NZS 61439
Low-voltage switchgear and controlgear assemblies — applied to every switchboard we design or modify.
IEC 62443
Our reference framework for OT network segmentation, access control, and security lifecycle management.
AS/NZS 3000
Wiring rules applied across all electrical design and installation work we scope or deliver.
ISA-101
HMI design philosophy — alarm rationalisation and operator interface standards baked into every screen we build.
AS 4806 / Functional Safety
Applied wherever safety instrumented functions form part of the control system scope.
ISO 9001-aligned QA
Factory acceptance testing, version control, and change management procedures on every project.
We're building the engineering team one senior hire at a time.
