IPART has completed 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.
Council has provided IPART with proposed revised costs for the priority stormwater basins in CP20 and CP21. This is a limited review of reasonableness of the construction costs for priority stormwater detention basins and associated soil disposal costs only.
We released a Draft Report on 8 January 2024 covering the terms of reference. Submissions closed on 26 January 2024.
IPART presented the Final Report to the Minister for Planning and Public Spaces on 26 February 2024.
