Our structure

Established in 1949, Leighton Contractors is a wholly owned subsidiary of Australian publicly listed company CIMIC Group Limited (ASX: CIM).

Leighton Contractors became the CIMIC Group’s construction company following a strategic review announced by its parent company (at that time known as Leighton Holdings Limited) in June 2014.

Our company combines the construction expertise and track record of three former leading companies:

  • The original 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
  • Leighton Asia, established in 1975 and headquartered in Hong Kong

Leighton Contractors includes the fully-owned subsidiary Broad, a national construction management company, with diverse capabilities backed by an experienced and passionate team.

The CIMIC Group’s Code of Business Conduct, including information on our confidential Ethics Line, has been introduced to allow our people to report in good faith any concerns about an actual or potential breach of the Code.
