I'm not sure what you're talking about specifically. Major projects is one of those.
The Privy Council Office tries to oversee all government priorities through the functioning of cabinet and the coordination of departments. On any government priority, whether it's related to major projects or something else, the Privy Council Office will work to ensure that cabinet discussions support this, that DM committees are put in place to support those priorities and that there's up-to-date tracking of progress on those priorities for the Prime Minister.
