Major projects authority MPA
The Major Projects Authority was established by the government to '...bring about the successful delivery of major projects across central Government by working with departments to ensure the fitness and quality of major projects throughout their life' (ref HM Treasury, Major project approval and assurance guidance).
- It requires HM Treasury approval.
- It could lead to a breach in departmental expenditure limits.
- It involves significant levels of unplanned spending.
- It could set an expensive precedent.
 Major projects procedures
Projects will generally be reviewed at the following stages:
- Starting gate review. A starting gate review is commissioned by submitting a Risk Potential Assessment (RPA) to the Major Projects Authority.
- Strategic outline case, before any public commitments are made (this may be preceded by OGC gateway review 1 or some other project assessment review (PAR)).
- Outline business case, before OJEU notices are placed (this may be preceded by OGC gateway review 2 or some other project assessment review (PAR)).
- Full business case, before contracts are finalised (this may be preceded by OGC gateway review 3 or some other project assessment review).
- Further project assessment reviews depending on the nature of the specific project. These may follow OGC gateway reviews.
- Consequential reviews for projects that are in difficulty.
- Major Projects Review Group (MPRG).
- Treasury Approval Point with panel meeting.
- Treasury Approval Point without panel meeting.
