BUILDING and construction projects that are in the pipeline and valued at more than $20 million are set to be fast-tracked under a South Australian Government initiative to support the construction sector.

Premier Jay Weatherill last week announced the initiative to intensively case manage projects to fruition in an effort to support the construction industry through a difficult period, adding there is a sense of urgency about the circumstances of the building and construction sector.

Mr Weatherill will ask the Economic Development Board, Urban Renewal Authority and Department of Planning, Transport and Infrastructure to prepare an assessment of shovel-ready construction projects valued at more than $20 million that are currently seeking approvals.

"Where additional work is required for approval to be granted, we will appoint a case manager for each project to help expedite the relevant approvals," Mr Weatherill said.

"This won't alter our existing planning, environmental and safety approvals system, which is the best in the nation."

Mr Weatherill said the State Government took a number of decisions in this year's Budget to respond to the critical situation facing the construction sector.

"Given the choice of retaining the AAA credit rating or continuing to invest in major infrastructure, we chose infrastructure to help sustain the level of activity within the economy – for example the Riverbank precinct, Adelaide Oval, Royal Adelaide Hospital and Southern Expressway duplication," Mr Weatherill said.

"The initiative we are announcing today is another step in supporting the building and construction sector."
