Mobile Automation delivered the complete electrical and communications services for a food producer's Melbourne facility, working to the builder's phase 2 construction program.
Tray and mains routes set out first
The backbone went in before anything could follow it.
- Suspended brackets cut from threaded rod and strut, hung from a roof six metres up
- Brackets levelled and squared before any tray was bolted down
- Fixings into sandwich-panel roofing silicone-sealed
- Waterfall and tee pieces so runs turn and branch without disturbing finished sections
- An 18 m run of 600 mm tray carried into the freezer
- Runs laser-measured before mains were pulled to each distribution board
Temporary supplies out, permanent supplies in
The work was sequenced to the builder's program.
- Temporary power and lighting feeding the site sheds and office workstations
- Temporary services removed area by area as each ceiling was closed
- Permanent luminaires, sensors and emergency fittings installed behind them
- Mains prepped and tied at DB2 and DB4 ahead of a weekend shutdown
- Main board and generator isolated and locked out and a redundant board removed
- New control panel and generator supply fitted off, then the site re-energised and tested
Cold rooms, ovens and door systems
Each production area set its own electrical requirement.
- Two floor-heating cables laid to the room layout diagram using heat-resistant tape
- Corrugated conduit protecting only the cold section through the floor
- A spare temperature probe run beside the working one
- Door heaters on dedicated isolators and transformers
- Ovens fed by 16 mm circuits to 80 A isolators set clear of the range hood
- Three robotic sliding doors supplied with power and push-button control
- Heat-trace, roller doors, cool room and high-care lighting as areas were released
The results
- Cat 6 to the office and time clocks, terminated into patch panels and labelled by category and number
- Plans recorded against the runs as installed
- Coordinated sub-mains serving the air-conditioning, fire, security and hydraulic switchboards
- Exit and emergency fittings labelled against the emergency plans and tested
- RCDs proven and board labels checked circuit by circuit against the outlets they feed
- Equipment stocktake compiled for the safety certificate
