Connecting Clients: Degnan
Building Tomorrow Together: 45 Years of Infrastructure in Live Rail Environments
Degnan is an Australian-owned construction company with more than 45 years of specialist experience delivering infrastructure projects across rail, energy, renewables, waste, and commercial construction. Founded in 1979, the business has grown from its NSW roots into a national operation with offices in Sydney, Brisbane, and Melbourne – and a reputation built on decades of delivering in some of Australia’s most complex, live environments.
Where did it all start for Degnan?
Degnan’s story begins in 1979 – a family-owned construction business that grew steadily by doing the hard work well. From its headquarters in Mortdale, Sydney, the business has expanded over four and a half decades to become one of Australia’s most respected specialist contractors in rail and infrastructure, with offices now in Brisbane and Melbourne.
What has remained constant throughout that growth is the philosophy: work closely with clients, deliver safely, and build something that lasts. That approach has earned Degnan long-standing relationships with government rail agencies across NSW and Queensland, and an expanding pipeline of energy and renewables work as Australia transitions to a cleaner grid.
Today, Degnan holds ISO 9001, 14001 and 45001 certifications and is accredited across multiple industry bodies including Master Builders Australia, TrackSafe, NAWIC, QMCA, QBCC, Supply Nation and MATES in Construction.
What does Degnan do and what makes them unique?
Degnan specialises in infrastructure projects that others find complex, constrained, or simply too difficult. Their four core service areas are:
Rail Infrastructure – Over 45 years of continuous work in live rail environments, covering station upgrades and restorations, signalling, refurbishments, escalator and lift replacements, maintenance facilities, and new station construction. Degnan’s methodology is built around minimising disruption to commuters and staff while delivering to the highest standard.
Energy and Renewables – Growing capability in power infrastructure, including substation delivery and projects at the intersection of energy and transport. As Australia’s infrastructure pipeline increasingly intersects with the energy transition, Degnan is positioned to serve both sectors simultaneously.
Waste and Recycling – Partnering with government and private clients on waste infrastructure projects that support community sustainability goals.
Commercial and Transport Construction – From operations centres to commercial building upgrades, bringing the same collaborative, quality-focused approach to projects beyond rail.
Their ‘One Safe Workplace’ framework drives safety outcomes across every project, and a commitment to social responsibility – including a published Reconciliation Action Plan, active gender equity programs through NAWIC, and membership of MATES in Construction – runs through the business from leadership to site.
Can you tell us about a project you’re particularly proud of?
Degnan’s legacy of delivering accessible, community-focused infrastructure is perhaps best illustrated by twenty years of work in the NSW Southern Highlands. In 2005, they upgraded Bowral Station. In 2019, Mittagong. And in July 2025, they completed the Moss Vale Station and Stabling Yard Upgrade – celebrating its opening with the local community, a Highlands Pipes and Drums welcome, the Country Women’s Association serving scones, and a heritage Picnic Steam Train arriving to mark the occasion.
“We’re proud to continue leading the way in making rail travel more inclusive for everyone. Thanks to every one of you – on site and behind the scenes – who helped make this project and event such a success.”
– Chris Degnan
That trifecta of Southern Highlands projects speaks to something deeper than construction capability: a contractor that builds lasting relationships with the communities and agencies they serve, and comes back to continue that work across decades.
Beyond rail accessibility, Degnan’s Como Station upgrade remains one of their most recognised achievements – winning both the NSW Banksia Foundation Clean Technology Award in 2021 and the National Banksia Clean Technology Award in 2022 for integrating renewable energy into station infrastructure in a way that set a new industry benchmark.

How can Degnan play an integral part for businesses across the infrastructure industry?
For contractors and government agencies navigating complex, regulated infrastructure environments, Degnan brings something rare: a contractor that genuinely understands the operational constraints of live environments, and has the track record to prove it.
Their Early Contractor Involvement (ECI) model is central to this. By bringing Degnan into a project during the planning and design phase – before contracts are fixed and programmes locked – clients benefit from decades of live-environment experience informing decisions that would otherwise be made in isolation. ECI reduces risk, improves buildability, and creates the kind of collaborative partnership that keeps complex projects on time and on budget.
Safety performance is another differentiator. Degnan’s ‘One Safe Workplace’ culture has been recognised nationally – including through the Australian Institute of Health and Safety, multiple RISSB commendations, and ongoing investment in mental health and wellbeing through MATES in Construction – and provides clients with confidence that their projects will be delivered to the highest safety standards in Australia’s most demanding work environments.
What’s next for Degnan?
Degnan’s focus for the next phase of growth is clear: deepen national presence, expand into energy and renewables, and continue building the people and systems that make complex delivery possible.
Queensland and Victoria are key growth markets. The Brisbane office is well positioned to capitalise on significant infrastructure investment flowing into the state ahead of the 2032 Olympics. The Melbourne office brings Degnan’s rail and transport expertise into a market with substantial station upgrade and network investment underway.
The energy sector represents a major opportunity. As Australia accelerates its transition to renewable energy, the intersection of rail and energy infrastructure – substations, power systems, electrification – is where Degnan’s experience in complex, regulated environments is directly transferable.
What won’t change is the approach – or the values. Every project, for Degnan, is a chance to build something that endures: for clients, for communities, and for the future.
