I believe that 20% was in reference to the decommissioning process. We are approximately 40% decommissioned. We're on track to finish those decommissioning activities in an August 2019 time frame, with a view of being able to transition the building back from parliamentary partners to PSPC, and then a very rapid turnover to our construction manager, who will take over custody of the site and stand up the construction site.
There are key elements that need to come out of the building. We've moved quite a bit of the moveable assets, things like artifacts and furniture, especially those to support parliamentary operations, but there are residual assets in the building and some pretty important artifacts. A good example are the war paintings in the Senate chamber. Two of the six are down, and the remaining six will be moved by a mid-June time frame.
Most importantly, on the House of Commons side, is the decommissioning of the IT infrastructure in the building. That is ongoing as we speak and is well in progress, but has to be completed, as well as some of the activities to isolate the building, so it can be taken essentially off the grid.
