1.84 The Input Value for Capital Expenditure for the PFI Option is assumed to be higher than the estimated costs under the Conventional Procurement Option. This reflects the fact that more cost and delay risk is transferred to the private sector under the PFI Option and that, typically, the PFI partner succeeds in passing many of these risks, albeit at a capped level, down to the construction contractor through sub-contract arrangements. The residual risk that remains with the PFI partner is reflected in the return on equity and senior debt required. Procuring Authorities should seek to test or tailor the Value to the requirements of the particular project being assessed. This might be achieved by, for example, Procuring Authorities studying the difference in construction prices per m2 between conventionally procured assets and/or services and the winning PFI bids for broadly similar projects.
