Comments
This article seems to need some revision: The Management Contracting and Construction Management procurement methods appear to be the wrong way round.
Construction Management is far higher risk than Management Contracting for the client.
The end of the article also doesn't seem to be consistent with the 'suitable for' and 'not suitable for'.
So change it - its a wiki site.
