Integrated testing of plumbing and passive fire systems provides a greater understanding of how components perform together within a building system.

It's not enough to erect fire-resistant walls and floors; we need an integrated system that accommodates all building services, plumbing, electrical cables, HVAC and drainage while preventing vertical fire spread, maintaining integrity under seismic or thermal movement, and preserving life-safety performance.

Post-tensioned concrete slabs, with their associated steel tendons, are a common construction technique in New Zealand for elevated slabs, residential buildings, and warehouses. These flooring systems, along with the building's other structural elements and services, can penetrate the slabs and fire cells, so each penetration needs to be treated to stop the spread of fire.

A thorough passive fire survey is essential. Identifying non-compliant penetrations allows for planned, rather than reactive, remediation.

Ten frequently asked questions that can help with general understanding and challenges that are regularly faced in the New Zealand construction industry.

Selecting product suppliers that offer integrated system solutions can avoid receiving conflicting information that occurs when suppliers work in fragmented categories.

Elements that improve structural performance during seismic events also introduce significant fire safety vulnerabilities in a building’s fire compartmentation strategy. Gaps created for movement can act as open pathways for smoke and flame. Careful selection and specification of fire-resistant materials can mitigate this risk.

Understanding and applying Test Standard AS1530.4 — Section 10.12 Permissible Variations to projects can dramatically increase the availability of passive fire stopping solutions.

As new pipe types emerge in the market, it is crucial to maintain up-to-date testing to address the unique requirements each type presents.

Opting for NZ made, tested and appraised passive fire solutions gives a level of assurance that other suppliers using offshore manufacturing are unable to provide.
