Transport Construction Authority

The Transport Construction Authority (TCA), formerly Transport Infrastructure Development Corporation (TIDC) prior to July 2010, was an agency of the Government of New South Wales that was responsible for new railway projects in the city of Sydney, Australia. On 1 November 2011 the Transport Construction Authority was subsumed into the newly-formed Transport for NSW.

History
The Transport Infrastructure Development Corporation (TIDC) was formed as part of the Transport portfolio and was charged with delivering a number of major public transport, in particular commuter rail, construction projects across the greater Sydney metropolitan area. The authority oversaw the process of planning, design, regulatory approval and community relations for its projects. Construction was performed by private-sector construction companies. When built, the infrastructure was turned over for management by CityRail.

The former chairman of TIDC was Ron Finlay, who served the role for 5 years. In 2006-2007 the TIDC was responsible for 11 projects under construction, collectively worth over A$3.2 billion, with another nine projects in the planning phase. Project expenditure for the year totaled A$629 million.

The TIDC was renamed the Transport Construction Authority on 1 July 2010. On 1 November 2011, the Transport Construction Authority was abolished and subsumed into Transport for NSW.
