Authorities procuring projects through PFI/PPP must comply with the Public Sector Directive 2004/18 (implemented by the Public Contracts (Scotland) Regulations 2006).
Authorities may also be required to submit reports ("Key Stage Reviews") to the Scottish Executive at certain points prior to commencement and during the formal procurement process. The submission of these reports is not a statutory requirement, but designed to ensure that the Scottish Executive is kept up to date with the progress of the project, and to encourage authorities to consider certain key issues early in the development of the project.
