Completing daily plant inspections and reporting maintenance requirements

service information and supervisor instructions
Assisting the wider crew with hands‐on civil construction duties when the excavator is not operating
Following SWMS, excavation permits, environmental controls and project procedures
Maintaining safe separation from underground and overhead services
Supporting day, night and emergency works when required

Watermain renewal or water-service repair experience
Pipe‐laying experience
HR or MR driver licence
Confined Space, Working at Heights and Gas Test Atmospheres qualifications
Dogging, lifting or other relevant plant tickets
Experience operating different excavator sizes and attachments
What We Offer
Full-time, ongoing employment
