Project Overview
Known as the Oswald Bond Store, this iconic heritage building was originally constructed in 1892 and has recently undergone a major refurbishment to transform it into 5,488 m² of premium office space spread across five levels. The redevelopment was carefully designed to preserve and showcase the building’s historic character while seamlessly integrating modern building services and amenities. The result is a workspace that celebrates Sydney’s architectural heritage while meeting the functional and sustainability standards of contemporary office environments.
Challenges
- The refurbishment involved a heritage-listed building, requiring modern services to be installed without compromising existing
- structures or aesthetics.
- The HVAC system featured 80-100mm insulated copper pipes, which needed to maintain their R-value while meeting fire-stopping requirements
- Traditional fire collars or wraps were unsuitable due to tight service penetrations and the need to preserve pipe insulation continuity.
- The system had to achieve up to a -/120/120 FRL in accordance with AS1530.4 to ensure compliance with modern building standards.
Solution
Understanding the complexities of working within a heritage structure, Trafalgar Fire’s engineers and system specialists provided dedicated on-site support to ensure compliance and installation accuracy:
- Coordination and Collaboration: Trafalgar Fire worked closely with the contractor, Australian Passive Fire, to review service penetrations and insulation continuity requirements. This collaborative approach ensured that both fire rating and thermal performance objectives were achieved without compromising the building’s heritage features.
- Project Specific Solution: Detailed instructions were issued outlining how to seal weak points in the lagging using Armaflex adhesive and vapour seal tape, minimising condensation risk and ensuring full system integrity through fire-rated barriers.
- Installation Inspections: Trafalgar Fire’s technical support provided follow-up support and inspections during installation to confirm correct application and compliance with AS 1530.4 testing standards.
The Trafalgar Approach
System
ArmaFlex Protect
Armaflex Protect is an all-in-one flexible pipe lagging with intumescent technology for fire barrier penetrations of hot and chilled-water services. Armaflex Protect allows pipes to pass through fire barriers without loss of thermal efficiencies, or risks of condensation caused by typical fire stopping systems which may require lagging to be stripped through fire barrier penetrations.
System
FyreBATT
Trafalgar FyreBATT’s are a coated mineral fibre product, designed for use as a fire seal for service penetrations. Consisting of a high-density fibrous lamella core, sealed on both sides with a flexible fire rated ablative coating, FyreBATT’s offer a high fire protection, along with an effective smoke and acoustic seal.
