Our approach
Smart, Transparent Service You Can Trust
Our maintenance is delivered on a fixed schedule using leading-edge workflow software. This ensures every required inspection happens on time and is fully documented.
GPS technology lets us provide accurate, time-stamped reporting, so you know exactly when and where checks were completed. All reports and certificates are stored for at least two years—meeting Building Act requirements and giving you a reliable paper trail.
What you need to know
Your Responsibilities Under the Building Act
As a commercial building owner, you must meet the Building Act 2004 requirements to maintain specific systems. Your compliance schedule, issued by your local council, details the systems you need to maintain—like SS9 mechanical ventilation.
Each year, you're required to have an updated, signed Building Warrant of Fitness (BWOF) displayed in the location specified on your schedule. This certificate must be visible for authorised personnel, including fire service staff, council inspectors and IQP personnel.
You’re also required to keep inspection reports and test certificates with your compliance schedule for a minimum of two years.
