We really do understand that cost is a critical factor in determining and informing the decisions along with other key aspects like, as you indicated earlier, the heritage interventions and things like that. We would never ask parliamentarians to make decisions without understanding those cost details.
In terms of the functional programming, we are here to start the engagement process to see if we have those options right in terms of their functional capabilities to support parliamentary operations. From there we are happy to re-engage and come back to provide you cost ranges on what that might mean. We are at step one of a further discussion about cost to help inform the decision-making process.
The other aspect is the comprehensive assessment program. It's also a key factor in what we learned about the building and what that will involve in terms of modernization. The combination of the functional program and the base-building modernization ultimately inform a building scope, and it's only from there that you can baseline your cost scope and schedule. As you can imagine, there's a very big difference, just to take the chamber, for example, between remaining within the existing chamber versus completely deconstructing a very significant portion of the building and rebuilding it.
We are really not trying to not provide those details, and we're happy to come back with that information. We just need to know and get a better sense, as part of the initial engagement, as to whether the hard work we've done at the staff level with the House of Commons administration is landing in terms of options that make sense operationally for Parliament.
