Cordell, in conjunction with the Housing Industry Association, have released a list of Australia's top 100 biggest civil construction companies. (See the full table at the bottom of the article).

For a breakdown of Tier 1, Tier 2 and Tier 3 contractors, check our our article here (it also has definitions of each tier).

The list outlines the top 100 largest construction companies in Australia across a variety of industry sectors. These include construction engineering, non-residential construction and many more.

Harley Dale, Chief Economist at Housing Industry Australia (HIA), said,

"Firms awarded contracts relating to the major transport infrastructure projects in New South Wales, Victoria, and South East Queensland have been the big winners in the latest HIA-Cordell Construction 100 list.

Biggest construction companies projects across Australia

Projects include WestConnex, Sydney's light rail network, significant upgrades to Melbourne's rail infrastructure including the level crossing removals, and the Toowoomba Second Range Crossing project."

CPB Contractors came out as the clear winner of Australia's top 100 construction firms, with a total of $13.59 billion worth of contracts won in the 2015-16 financial year. Most of CPB Contractors' work was around civil engineering projects, however, they've picked up plenty of mining and commercial construction work.

Lendlease picked up second place in the list of Australia's top 100 construction firms, with a significant margin between them and CPB Contractors. They pulled in $8.29 billion worth of work in the 2015-16 financial year.

Laing O'Rourke came in at a very respectable third. They won $5.3 billion worth of work over a successful year. In fourth place was Hutchinson Builders, who keep charging ahead in residential construction. Fifth place was taken by Probuild Constructions, who operate in a similar arena to Hutchies.

Many of the major firms that fill out the money end of Australia's top 100 construction firms have made a successful transition from high mining involvement to commercial and residential construction.

Continued growth for big civil contractors and engineering companies

The ongoing housing boom has made the transition easier. Harley Dale said:

"The buoyant conditions in the key east coast housing markets also saw a substantial increase in the number of property transactions. With state governments taking a clip on every transaction, stamp-duty revenue growth over the last couple of years exceeded even the most optimistic of forecasts."

"While finding a replacement to this highly inefficient tax is an obvious policy reform priority, this revenue windfall for state governments on the east coast has been instrumental in funding the growth in infrastructure investment evident in the order books of the nation's largest contractors. Hopefully, this could pave the way for a broader recovery in non-mining private sector investment in the next phase of the transition,"

The outlook for the 2016-17 financial year is already looking positive. Many of the incumbents in the list of Australia's top 100 construction firms have already been successful in securing more work. As NSW continues to ramp up infrastructure spending and the housing boom keeps charging along, most firms should be able to find big projects to keep them going.

With $13.591 billion in total contracts awarded during the year, the total value of contracts awarded to CPB was more than twice as large as the next company (Lendlease).

CPB Contractors mining arm Thiess also recorded $1.751 in won contracts, which would mean it alone would have been the 6th largest company on the list.
