Construction & Major Projects

More and higher quality infrastructure remains an urgent priority in Australia as the population continues to increase.

The industry has a relatively small window in which to deliver nationally significant projects while balancing quality and cost.

How we can help

Sponsors, investors, contractors, developers, operators of infrastructure assets and all levels of Government come to us for advice across the lifecycle of major projects.

Helping you manage the process and deliver the outcomes you want

Complex multiparty projects call for a business partner with the right mix of technical skills, sector experience and industry insight.

Providing you with confidence and certainty for one of a kind transactions

Unique transactions call for renowned market leaders who can support you across the lifecycle of an asset, from origination to end of life.


The right market intelligence to deliver fast outcomes

Bringing deep insight drawn from cutting edge transactions, delivered by our stable team that retains and builds asset knowledge over the long term.


From procurement design, probity and tendering, through to delivery advisory services and dispute resolution. We have the necessary technical expertise, experience and industry knowledge to assist across all stages of the construction cycle and across all procurement methodologies, including:

  • traditional procurement (eg D&C, EPC, Build-Only and BOOT) and public-private partnerships;
  • unsolicited and market-led proposals;
  • operator-led infrastructure delivery and services outsourcing (eg O&M, WOM, services contracts and concessions); and
