3.36 It is important, therefore, that the CPAM is presented in a clear format and that any changes since OBC stage are fully explained.
3.37 The presentation of the CPAM should include the contents indicated in the Scottish Capital Investment Manual Business Case Guide and the Treasury Taskforce Technical Note No. 4. The CPAM should fully detail:
• the design solution on which the CPAM is based;
• the way in which the CPAM has developed over the life of the procurement process, and why; and
• the detailed assumptions on which the cost of the CPAM is based.
3.38 It is important that the NHS body details and explains any differences between the CPAM and PPP solutions. The CPAM section should summarise the functional specifications of each option (in terms of bed numbers, area, design solution, etc) and fully explain any differences.
3.39 Finally, the CPAM section should discuss the qualitative features of the PPP and CPAM schemes and make clear their respective advantages/disadvantages. These could be assessed by means of a weighting and scoring analysis.
