3.1 The process used to assess the "PPP ability" of the proposed scheme is as follows:
• An initial assessment looking at 'Internal Factors' covering organisational, financial and other aspects known to have a major influence on participants when considering which schemes to bid for.
• A secondary detailed qualitative 'External Factors' assessment of the scheme to match it against well-proven parameters needs to be undertaken. The assessment uses a range of broad categories to examine the potential for a successful PPP solution. These factors are scored and weighted to give an overall qualitative assessment of PPP potential.
• Assuming the project is appropriate for PPP a subsequent quantitative assessment will also be undertaken. In cases where the qualitative assessment indicates that there is significant scope for the project to attract private sector interest but where the OBC indicates that scheme affordability is likely to be a key determinant in securing approval shadow bid affordability modelling will be required.
3.2 This tool has been developed based on a review of recent PPP schemes, coupled with in-depth knowledge from working with a number of major contractors and taking account of their preparation and assessment of factors in considering which schemes to bid for.
