Wet Fire Systems Design

Specialist design for reliable, coordinated and compliant fire protection — sprinklers, hydrants, hose reels, fire pumps and water storage.

A wet fire system must be carefully designed around the building's use, fire hazards, construction, water supply and approval requirements. Effective design is not simply a matter of placing sprinklers, hydrants or hose reels on a drawing — it requires a coordinated engineering approach that considers how the complete system will operate during a fire emergency.

We provide professional wet fire systems design consultancy for new buildings, refurbishments, alterations and upgrades to existing properties, undertaken with reference to the National Construction Code, relevant Australian Standards and project-specific documentation.
