Ductwork for Government Buildings & Public Infrastructure
Ducting That Keeps Public Infrastructure Running Smoothly
- 50+ Years Australian Experience
- AS 4254.2 Certified
- Guaranteed On-Time Delivery
- Fully Insured

In government buildings, facilities of local authorities, and public infrastructure, getting the air right isn’t optional. Offices, libraries, stations, and community hubs all need reliable airflow, steady temperatures, and systems that can take the load without cutting corners or driving up energy costs.
At Kavanagh Industries, we build ductwork that does the job properly. It moves air where it needs to go, keeps pressure balanced, handles heat and contaminants, and stays compliant with the standards that matter. We offer well-built systems made for public spaces.

Our Ductwork Range
We build ductwork that’s made to fit public buildings and infrastructure jobs. No guesswork, no off-the-shelf shortcuts. Just solid gear, made to spec, with durable components, and ready to go:
Ductwork Applications for Government Buildings & Public Infrastructure
We supply fabricated duct systems built to handle the everyday demands of public buildings. From civic centres to transport terminals, we deliver ductwork that works where it’s needed and holds up over time:

Offices, Chambers, and Admin Buildings
We build ductwork that keeps public offices, council chambers, and service centres comfortable and quiet. You’ll get steady airflow, proper zoning, and reliable temperature control across open-plan workspaces and private rooms, including space heating where needed.

Libraries, Community Centres, and Public Halls
These spaces see high foot traffic and changing loads throughout the day. Our ductwork manages airflow and temperature evenly, ensuring staff and visitors alike enjoy clean air and a comfortable environment.

Toilets, Change Rooms, and Amenities
We supply exhaust systems that handle odours and humidity without fuss. Designed to meet code and air change requirements, these systems keep restrooms, parents’ rooms, and end-of-trip facilities clean and operational.

Transport Hubs, Depots, and Carparks
From bus depots to train stations and underground parking, we build ducting that handles fume extraction, smoke control, and air exchange. Built to take long runs, full load demand, high pressure, and meet AS 1668.1 where required.

Mechanical Plant Areas & Risers
We supply ducting for plant rooms, air handlers, fans, and vertical risers that keep HVAC systems running properly. Everything’s made for access, airflow, and easy integration with control systems.

Custom Fit-Outs for Public Spaces
Got a courtroom with strict acoustic needs? A museum with humidity control? A civic centre with odd ceiling heights? We design and build ductwork to suit the space. If it needs air, we’ll get it sorted.
Why Government Contractors Work With Kavanagh
When you’re delivering a public project, things need to run on time, meet code, and stand up to years of service. That includes the ductwork. At Kavanagh Industries, we know how these jobs operate, and we build systems that fit the brief and get the job done.
Here’s how we approach ductwork for government and public infrastructure:
Public budgets need to go the distance. We help by offering:
- Clear, Detailed Quotes: We work directly with your mechanical contractor or services team to supply a line-by-line breakdown. You’ll know what’s included, where it goes, and how it fits into the project scope.
- Made to Support Energy Efficiency: Our ducting systems help minimise pressure losses, improve heating and air conditioning, reduce energy consumption, and deliver long-term energy savings across public facilities. They also integrate well with modern heat pumps to support sustainable climate control.
- Materials Built to Last: We use high-grade galvanised steel, Bluescope stainless, fire-rated insulation, and low-VOC sealants. It’s all made to stand up to heavy use and changing loads over time.
Timelines on government builds are tight, and delays cost more than money. We’re set up to deliver on time and in full.
- Fast, Reliable Turnarounds: With serious manufacturing capacity and a tight production line, we hit delivery targets and can fast-track urgent orders in 24 hours when needed.
- Ready to Install: We supply ductwork that’s sealed, colour-coded, and delivered with matching drawings to streamline installation.
- Delivery That Works for You: Our in-house fleet is GPS-tracked and handled by drivers who know how to work around busy sites. We plan drop-offs to match install phases or public access hours if you’re working on a live site with safety constraints.
In government buildings and public infrastructure, heat transfer and air conditioning systems need to work as they should. We can help with that.
- Consistent Climate Across Large Areas: Our ductwork is designed to deliver even temperatures and reliable cooling and airflow across all corners of a building.
- Cleaner, Healthier Air: Good ventilation make a big difference in high-traffic public spaces. Our ventilation systems help move stale air out and fresh air in, supporting better indoor air quality that’s easier to maintain over time.
- Noise-Controlled and Neat: We build sealed systems that reduce vibration and improve flow without noise. If ductwork is visible in ceilings or public-facing areas, we can supply round, oval or spiral profiles that deliver conditioned air without disrupting the design.
These projects need certainty, not surprises. That’s why clients stick with us.
- Fully Compliant and Ready to Go: Every system we build is compliant with AS 4254.2 and other relevant codes. We’re also fully insured, and our documentation is clear and complete from the outset.
- Built on Experience: We’ve been manufacturing ductwork in Australia for over 50 years. Our team knows how to deliver systems that meet the practical demands of government projects and HVAC equipment, no matter how large, small, or complex.
- We’ll Work With You: From early quoting through to site delivery, we stay responsive. If you need advice on materials, lead times, creating custom solutions, or coordination with other trades and keeping operations running smoothly on site, our team can help.
