The Project Control Framework
This framework sets out how we, together with the Department for Transport, manage and deliver major road improvement projects.
Public Sector Comparator and Contingent Schemes
Public Sector Comparator
For each DBFO project, the Agency needs to decide whether the proposed contract offers value for money compared with conventional procurement. To assist in this decision the Agency prepares a Public Sector Comparator (PSC), which is calculated by costing what the public sector would have had to pay to procure the construction of the relevant schemes and the operation and maintenance of the project road over 30 years by traditional means. The calculation includes an assessment of the risk resting with the Agency under conventional procurement.
The Agency prepares an assessment of Net Present Value (NPV) of the PSC, and compares this with the NPV of the projected payment under the DBFO contract (although the Agency has also to take into account other value for money considerations which may not be quantifiable but may be significant, for example, environmental considerations or other policy objectives).
Taking into account all these considerations, the Agency's Accounting Officer (the Agency's Chief Executive, who is answerable to Parliament for the Agency's commitments) needs to be satisfied that value for money is best achieved by means of the DBFO contract.
