tv105,

The progress report outlined some good working examples which give I wouldn't class as 'blind faith' or 'scepticism'.

"Infrastructure costs are currently running at $16m under budget compared to pre-development costing studies. Highly proficient management of assets, and innovative development methods, are resulting in considerable time and costs savings throughout the project.
By way of example, the use of large scrapers for removal and storing of organic and top soil for later use in rehabilitation, is costing an average of approximately $1.10 per Bank Cubic Metre (BCM), compared to pre-development estimates of $3.50 per BCM. The Project currently has two teams of 3 Scrapper each, moving a total of 16,000 BCM’s per day.
The Diversion Channel was estimated at $8.50 per BCM in pre-development studies, and is currently averaging just $3.50 per BCM."
