Government and defence projects set the bar for facade procurement in Australia. The compliance expectations are thorough, the documentation standards are exacting, and the buildings are designed to remain in service for decades. These are not projects where assumptions or shortcuts survive the approval process.
Valmond & Gibson has supplied aluminium facade systems to a range of government and defence projects — from naval base upgrades in Canberra and Western Australia to civic buildings across the ACT. This is a practical guide to what makes facade procurement different in this sector, why Australian-made matters, and which systems suit which project types.
What makes government and defence facade procurement different?
Government construction procurement operates under the Commonwealth Procurement Rules (CPRs), which were updated in November 2025. These rules require value for money as the core principle, but value for money in a government context means more than lowest price. It includes fitness for purpose, whole-of-life cost, compliance certainty, and — increasingly — Australian industry participation.
For procurements above $20 million, Commonwealth Australian Industry Participation (CAIP) requirements apply. These require that Australian businesses are given full, fair and reasonable opportunity to supply goods and services on the project. Defence construction procurements valued at $7.5 million or more trigger additional local industry participation obligations under the Defence Policy for Industry Participation. Contractors must submit a Local Industry Capability Plan and report on its implementation.
In practical terms, this means government projects actively assess whether specified products and materials can be sourced from Australian manufacturers and supply chains. A facade system that is designed, extruded, or fabricated in Australia has a tangible advantage over one that is entirely imported.
Defence projects add further layers. Base access for construction personnel requires security clearances — typically Baseline clearances at a minimum, with higher levels for sensitive facilities. This applies not just to the construction phase but to any future maintenance or replacement work. A facade that needs regular specialist maintenance by personnel who each require security vetting and escorted base access is a cost and logistics problem that compounds over the life of the building.
Compliance documentation is scrutinised more carefully on government projects than on almost any other building type. Government certifiers and project managers expect complete, product-specific compliance packs — not generic material data sheets. Test reports must be from NATA-accredited laboratories, and every claim must be traceable to a specific standard and report number.
Why does Australian-made content matter for these projects?
Australian content is not a soft preference on government projects. It is a formal assessment criterion embedded in procurement frameworks at both Commonwealth and state levels.
The 165CW unitised curtain wall system is designed, engineered, and extruded in Australia. The extrusion alloys — 6060-T6 for primary framing, 6060-T5 for secondary framing, and 6005A-T6 for structural members — are produced domestically through Capral, Australia’s largest aluminium extruder. The LogiKal software database is purpose-built for the system. This is not a rebadged import. It is an Australian-designed system manufactured on Australian extrusion lines.
For interloQ interlocking rainscreen panels, extrusion dies exist both in China and with Capral in Australia. This gives project teams the option to source interloQ profiles domestically when Australian content is a contractual requirement — without changing the product specification or performance characteristics.
This distinction matters. When a head contractor is completing an Australian Industry Participation plan and needs to demonstrate local content in the facade package, being able to point to Australian-designed, Australian-extruded aluminium systems is a straightforward answer to a question that other suppliers may struggle with.
Which systems suit government and defence projects?
Government buildings range from high-security defence facilities to civic libraries, and the facade requirements vary accordingly. Here is how Valmond & Gibson’s systems map to common project types in this sector.
165CW unitised curtain wall — headquarters, administrative buildings, and civic precincts
Large government buildings — departmental headquarters, civic centres, courts, and administrative complexes — typically feature significant glazed facades. These buildings need natural light for workplace amenity, thermal performance for energy efficiency under NCC Section J, and a facade system that can handle the structural loads and movement demands of multi-storey construction.
The 165CW system is well suited to these applications. It accommodates insulated glass units from 24mm to 40mm, includes thermally broken glazing adaptors with polyamide strips, and provides integrated horizontal and vertical sunshade brackets for solar control. The unitised panel format — fabricated off-site and hung on-site — reduces on-site construction time, which matters on government projects where program certainty is a contractual obligation.
Valmond & Gibson supplied the 165CW system for the Land 400 School of Armour at Puckapunyal in Victoria — a Defence training facility that required both curtain wall performance and compliance with Defence estate standards.
interloQ interlocking rainscreen — barracks, accommodation, and base buildings
Defence base buildings — accommodation blocks, mess halls, training facilities, and support buildings — need durable, low-maintenance facades that perform reliably in environments where routine maintenance access is constrained by security requirements. interloQ panels are non-combustible (tested to AS1530.1 by CSIRO, Report FNC12595), weather-tested to AS/NZS 4284:2008 at 1500Pa serviceability limit state, and available in powder coat, anodised, and woodgrain finishes.
The rainscreen principle — panels fixed to a drained and ventilated cavity — provides inherent weather performance and allows moisture management behind the facade. Panels are individually interchangeable, meaning a damaged panel can be replaced without disturbing adjacent panels or requiring scaffold access to an entire elevation.
HMAS Harman in Canberra — the Royal Australian Navy’s communications station — features both interloQ and 165CW systems supplied by Valmond & Gibson. HMAS Stirling in Western Australia, the Navy’s primary fleet base on the west coast, is another defence project where Valmond & Gibson has supplied facade systems.
element13 solid aluminium panels — plant rooms, services, and secure zones
Government and defence buildings include functional areas — plant rooms, services enclosures, loading docks, and secure perimeter buildings — where a solid, non-combustible cladding panel is the right solution. element13 3mm solid aluminium panels are tested to AS1530.1 (non-combustible) and AS1530.3 (ignitability 0, heat 0, flame 0, smoke 1), with structural wind load testing to cyclonic standards (SLS 1875Pa, ULS 5559Pa). PVDF paint finishes provide long-term UV and corrosion resistance.
For secure zones on defence facilities, solid aluminium panels provide a robust external envelope with no gaps, joints, or ventilated cavities that could create surveillance or security concerns.
conneQt aluminium battens — screening, solar control, and facade features
Government buildings frequently incorporate external screening — whether for solar control on north and west facades, plant room ventilation screening, or architectural expression. conneQt aluminium battens and adaptors integrate with both interloQ and element13, providing a non-combustible screening system in vertical or horizontal configurations.
What do government certifiers expect from facade documentation?
Government certifiers are thorough. The documentation standard on a Commonwealth or state government project is typically higher than on a private commercial project, and for good reason — public money, public accountability, and buildings that are expected to last 50 years or more.
At a minimum, government projects require:
- AS1530.1 combustibility test reports from a NATA-accredited laboratory, specific to each product — not generic aluminium data
- AS/NZS 4284 weather performance test reports demonstrating the system has been tested as an assembly, not just individual components
- Structural assessments confirming wind load capacity for the specific site and building height
- Material certificates confirming alloy grade, temper, and coating specifications
- Warranty documentation that clearly states coverage, conditions, and duration
- Installation guidance that demonstrates the system is designed to be installed correctly and maintained over its service life
All Valmond & Gibson systems are supplied with product-specific compliance packs containing NATA-accredited test reports, technical manuals, and warranty documentation. These packs are designed to give certifiers exactly what they need — clear, traceable, product-specific evidence that the system meets the relevant NCC provisions.
Design life and whole-of-life performance
Government buildings are long-life assets. The Australian government’s design standards and state infrastructure guidelines typically require a minimum design life of 50 years for permanent buildings, and many government buildings remain in service well beyond that. Defence facilities, in particular, are strategic assets that are expected to operate for decades with minimal disruption.
Aluminium does not rot, rust, warp, or degrade under UV exposure. It is dimensionally stable across temperature extremes and does not support biological growth. With appropriate coating systems — PVDF for element13 panels, powder coat or anodise for interloQ and 165CW profiles — aluminium facades maintain their structural integrity and appearance for the full design life of the building.
This is particularly relevant on defence bases, where facade maintenance is not a matter of calling a contractor. Maintenance on a secure base involves security clearance checks, base access coordination, and potentially escorted access for all personnel. A facade system that performs reliably for 50 years with only periodic cleaning — mild detergent and water, no specialist treatments — removes a recurring logistical and security burden that other materials would impose.
Valmond & Gibson has supplied aluminium facade systems to government and defence projects across Australia, including HMAS Harman (ACT), HMAS Stirling (WA), the Land 400 School of Armour (Puckapunyal, VIC), and civic buildings throughout the ACT. Each of these projects required non-combustible performance, thorough compliance documentation, and products that could withstand the scrutiny of government procurement and certification processes. That is the standard Valmond & Gibson works to on every project.
