Passive Fire Systems Design

Ensuring buildings achieve the required fire resistance, life safety and regulatory compliance — across commercial, residential, industrial, healthcare and infrastructure projects.

Our design solutions are developed in accordance with the requirements of AS 1530.4-2014, AS 4072.1 and the National Construction Code (NCC), including Clause C4D15 — ensuring that fire-resisting building elements and service penetrations maintain their required Fire Resistance Level (FRL).

Our Passive Fire Design Services

Passive Fire System Design

Designs that preserve the integrity of fire-rated walls, floors, shafts and other fire-resisting building elements — including service penetrations, construction joints, movement joints and fire-stopping.

Fire Penetration & Joint Sealing Design

Engineered solutions for the fire protection of mechanical, electrical, hydraulic, communications and building services penetrations, using tested and approved systems.

NCC Compliance Assessment

Review of project designs and construction details against NCC requirements, including Clause C4D15, to verify passive fire protection performance.

Design Documentation & Specification

Detailed passive fire protection drawings, specifications, schedules and compliance documentation to support approvals, construction and certification.

Construction & Certification Support

Working closely with architects, engineers, builders, contractors and certifiers to ensure passive fire systems are correctly designed, installed and documented.
