We design the systems
that keep your plant running.
PLC, SCADA and HMI engineering for water, manufacturing, renewables and marine sites — built by a senior controls engineer, with direct access to the person doing the work.
Engineering across the full control system lifecycle
From a single control philosophy document to a fully commissioned panel — scoped and delivered by the engineer you spoke to.
PLC Programming
Ladder logic, structured text and function block programming for Allen-Bradley, Siemens and Schneider platforms — written to be handed over, not just to work.
HMI & SCADA Design
Operator interfaces and supervisory systems that give your team clear visibility of the process, from a single skid to a full site.
Control Panel Design
Panel layout, schematics and documentation aligned to AS/NZS 3000 and 61439, ready for build or panel-shop handover.
Commissioning & Site Support
FAT, SAT, loop checks and start-up support on site — plus troubleshooting when something needs to keep running today.
Systems Integration
Bringing new drives, VSDs, instrumentation and equipment into existing control architecture without disrupting production.
Upgrades & Migrations
Obsolete PLC and SCADA replacement, migrated across with minimal downtime and full as-built documentation left behind.
How a project actually runs
Five stages, the same engineer from first site visit to final handover.
Assess
Site visit, P&ID and process review, understand what the system needs to do and what constraints it's working within.
Design
Control philosophy, panel design and software architecture, documented before anything is built.
Build & Program
Panel build coordination, PLC and HMI programming, factory acceptance testing against the agreed spec.
Commission
Site acceptance testing, loop checks and start-up support, working around your production schedule.
Support
Ongoing maintenance, callout and optimisation once the system is in service.
Sectors we build for
Water & Utilities
Treatment plants, pump stations and network monitoring control systems.
Manufacturing
Process lines, packaging and material handling automation.
Renewables
Solar and battery site control, monitoring and grid interface systems.
Marine
Vessel and port-side control systems, from propulsion support to shore power.
Senior engineering, without the overhead of a big firm
UHD Controls was founded by Arsalan Junaid, a senior controls systems engineer, to give water, manufacturing, renewables and marine clients direct access to experienced engineering — without the account layers of a large integrator.
Every project is scoped, designed and delivered by the same engineer, from first site visit through to commissioning and support. [Edit this paragraph with your specific background, certifications and notable projects.]
