5.3.1 General Principles 

As PFI/PPP contracts tend to be at least 25 years in duration, it is inevitable that there will be a need for some form of change to the Facility and/or Services over time.

Section 5.2 above highlights the value to both the Authority and Contractor of well documented change control procedures for changes initiated by the Authority. There also need to be similar processes in place for changes initiated by the Contractor.
