Additional Thickness & Upgrade Works
Additional fireproofing thickness works where required by project specifications, inspections or revised requirements.
Additional Thickness & Upgrade Works across Sydney & NSW
Where inspections, revised fire engineering or updated specifications call for additional fireproofing thickness, A&D Warner can prepare and apply additional material to bring elements up to the required fire-resistance level. We undertake upgrade works on both new construction and existing buildings across NSW.
What's included
- Additional thickness application to existing fireproofing
- Upgrade works following inspections or revised fire engineering
- Thickness testing to specified fire-resistance levels
- Photographic and project QA documentation
For project pricing, please send through drawings, specifications, quantities and any relevant fire engineering requirements where available.

Common questions about additional thickness & upgrade works on commercial construction projects across Sydney and NSW.
What fire resistance level (FRL) do you deliver?
We work to the FRLs nominated in your project specifications and fire engineering report — commonly -/60/60, -/120/120, -/180/180 and -/240/240 for structural steel members. Our crews apply to specified thickness and verify throughout the works.
Do you service areas outside Sydney?
Yes. We service Sydney metro and projects state-wide across NSW — including Newcastle, Wollongong, Central Coast, Parramatta, Penrith, Liverpool, Campbelltown, Blacktown and North Sydney.
What information do you need for a project quote?
Drawings (PDF or DWG), project specifications, quantities (m² of structural steel or ductwork) and any fire engineering report. We can often give an indicative price from marked-up drawings, with a final figure after a site visit.
Do you provide QA documentation and thickness checks?
Yes. Every project includes thickness checks against the specified FRL, photographic records during application, and project-specific QA documentation suitable for handover to builders, fire engineers and certifiers.
