Before its collapse, Walter Construction had two divisions: "Construction and Civil", and "Mining". While the mining division was profitable and expanding, the construction division had been losing money since 2000. By the company's collapse, 18 of its 21 contracts were
cash flow negative. During this period the company heavily relied on its parent company for financial support, however Walter Bau was also experiencing financial difficulties and both companies were placed into liquidation on 3 February 2005.
KordaMentha was appointed the
administrator, and proceeded to liquidate the remaining assets of the company by 2018. During their investigation, it was also revealed that Walter Construction had
traded while insolvent. Prior to the collapse,
John Holland Group had a bid to acquire Walter Construction, however the deal fell through in 2002. ==Notable projects==
