What the Tier 1s do, what specialist civil contractors do, and the six questions that tell you which one your project needs.
The market
Civil construction in Australia runs in tiers. At the top are the Tier 1 head contractors such as CPB Contractors, John Holland, Acciona, Fulton Hogan, Laing O’Rourke and McConnell Dowell. They win the largest road, rail, tunnel and utilities programmes, carry the risk and manage the programme. Below them sit the Tier 2 contractors, and below those the specialists.
Underneath them sits the layer that actually moves the dirt, lays the pipe and pours the concrete: specialist civil contractors who self perform defined packages with their own crews and plant. That is where Quality Civil Solutions sits. QCS was founded in 2024 by leaders with more than 25 years of Tier 1 infrastructure delivery between them, to bring that discipline to civil packages of every size.
This page explains the difference plainly so you can choose the right kind of contractor for your project.
Compared
| What matters | Tier 1 head contractor | Specialist civil contractor (QCS) |
|---|---|---|
| Typical engagement | Head contract on programmes from hundreds of millions to billions of dollars | Civil packages from a single culvert or earthworks stage to the full civil scope of a subdivision, precinct or transport works package |
| Who does the work | Largely subcontracted to specialist contractors, managed by the Tier 1 | The QCS team and the QCS fleet. One accountable team |
| Systems and safety | Tier 1 management systems | Proven systems from leaders with Tier 1 infrastructure experience |
| Scale | National programmes | Civil packages, from a single structure to a full development |
| Best fit | State significant infrastructure programmes with design and delivery risk to carry | A defined civil package that needs to be delivered properly, on time, by one team |
| Where | National | Victoria, South Australia and Queensland from Essendon Fields, Gilman and Stapylton |
| Disciplines | Everything, through the supply chain | Earthworks, road and rail, drainage and underground services, structural and civil concrete, subdivisions, NDD and plant hire |
How to choose

What QCS delivers
The Tier 1 group includes CPB Contractors, John Holland, Acciona, Fulton Hogan, Laing O’Rourke and McConnell Dowell. They are the head contractors on the largest road, rail, tunnel and utilities programmes, and much of the work on those programmes is delivered by specialist civil contractors.
A Tier 1 holds the head contract, carries the balance sheet and manages the whole programme. A specialist civil contractor like QCS self performs defined packages: earthworks, drainage, concrete, pavements and NDD. The specialist is the team on the ground doing the work.
A programme with design and delivery risk to carry across hundreds of millions of dollars needs a head contractor. A defined civil package needs a contractor who will self perform it and answer for the result.
Ask where the leadership learned its systems, ask about safety and quality processes, ask what plant they run, and ask who will be on site running the job.
QCS was founded in 2024 by industry leaders with extensive Tier 1 infrastructure experience. The leadership team has successfully delivered some of Australia’s most complex civil and transport infrastructure projects.
