A quick update on remediation costs

Yesterday 24/8 I mentioned the proposed footprint of the hospital is about 2 ha, yet when we apply a simple logic to the proposals, the footprind could be 10 times that.     If we presume a linear relationship between volume of soil to be removed and treated and the cost then the estimated cost of $200m will be 10 times that.     As the clay layer slopes towards the Torrens then thwe larger the area the greater the depth of soil to be removed so the cost would be more than 10 times the estimate.     If that is so then the $2bn remediation added to the original published estimate of $1.7bn gets nearer to the estimate claimed by Isobel Redmond of more than $3bn.       We might as well build an Adelaide Oval with the small change!!     So Messres Rann, Foley Conlon and Hill where do the actual costs lie?
