CPB Contractors

CPB Contractors is the CIMIC Group’s construction company, with a team of around 23,000 people working at operations across Australia, New Zealand, Papua New Guinea, Asia and India.

CPB Contractors combines the construction expertise and track record of two leading companies:

  • The former Leighton Contractors, which was the founding company of the CIMIC Group in 1949.
  • Thiess, formed in 1934 and now operating as the mining company of the CIMIC Group.

CPB Contractors delivers major projects across all key sectors of the construction industry, including roads, rail, tunnelling, defence and building.

Working closely with clients and partners, its projects connect communities, play a key role in urban and rural development, help drive economic growth and provide vital, long-term infrastructure.

Its work covers a range of delivery models, including design and construct, construct only, construction management, Alliances and Joint Ventures, and Public Private Partnerships (PPPs) in conjunction with CIMIC’s Pacific Partnerships.
