Thank you for that question.
There's a wide range of activity in the department, so that speaks to some of the high numbers. In particular, in areas like construction, as you can appreciate, when a building is designed—take the parliamentary precinct project—we don't have in-house architects or designers who would do that work. We do that on contract.
We spoke earlier about ship retrofit and repair. Again, those are contracted services. We have other maintenance services for our real property portfolio.
There's a wide range of activity that we, over many years, have done through contracts and not through the in-house activities of government. That's the main reason you'll see PSPC as having generally a pretty high number of professional services contracts.
