The Work Team shall ensure that the cost and income analysis is based on actual and/or similar recent projects delivered under public procurement, taking into consideration the performance standards or service levels of an equivalent level as that of the Privatization option. If there is no data available on actual or similar projects delivered, then the Work Team shall obtain appropriate professional expertise in that specific asset area to compile the requisite costs.
The Work Team shall document the assumptions made and sources used to arrive at these costs and income, separately as an annex to the spreadsheet model. The assumptions shall be clearly explained and the sources referenced appropriately through source documents, links to data sources, etc. See Tables 5 and 6 (in the Templates below) for an example of how the assumptions should be set out for the PSC and the Privatization Option.
