Dnata Perth Control System Upgrade 

Scope of Work

Upgrade and replace the controls system supporting Dnata’s refrigeration and mechanical services, while keeping critical refrigeration running throughout. Works were staged to maintain continuous operation for an active airport catering facility.

Project Details

Controls System Replacement 

Replace ageing control gear with updated controls equipment to improve reliability and ongoing supportability. The upgrade was delivered in a way that kept refrigeration and associated mechanical systems operating. 

 

New Automation Hardware and Panel Rework 

Install new automation hardware and rework existing panel layouts to improve clarity and serviceability. The finished setup was organised, clearly arranged, and built for more dependable day-to-day operation. 

 

Staged Cutover, Testing, and Commissioning 

Plan and execute each changeover step-by-step to avoid downtime. Each stage was checked and tested before moving to the next, keeping the site online while the controls upgrade was completed.

 

Project Challenges and Solutions 

 

Maintaining Refrigeration with Zero Downtime 

Refrigeration was required to remain online throughout. The team staged cutovers carefully and verified each stage before proceeding to keep systems running continuously. 

 

Working within Live Airport Catering Operations 

The facility needed to stay productive while works progressed. Strong communication, coordination, and tidy work practices kept the upgrade on track without disrupting operations. 

 

Client Response 

The client was relieved the refrigeration and mechanical systems stayed online throughout, with no interruption to catering output. They also appreciated the cleaner panel layout and the improved visibility and control the upgraded system provides for daily operations.
