IPART will commence a targeted assessment of construction costs for priority stormwater detention basins and associated soil disposal costs in Blacktown City Council's Contribution Plans No. 20 Riverstone and Alex Avenue (CP20) and No. 21 Marsden Park (CP21). In our prior reviews we recommended removing $140 million of soil disposal costs from the cost of essential works for CP20 and $95 million of stormwater infrastructure costs from CP21.
This is a limited review of reasonableness of the construction costs for priority stormwater detention basins and associated soil disposal costs only.
We will provide our final assessment and recommendations to the Minister.
