I mentioned that there were previous buildings there. Depending on the age of the building, there could be some abatement work that is necessary in terms of removing potentially hazardous materials. We know that some construction material that was used in the past is obviously no longer used, and it can be dangerous if it's not properly disposed of. From an abatement perspective, that would have been part of the preparation for the demolition work that had to be undertaken by the NCC prior to the construction of it.
I also understand that there was soil contamination in some of the soil around the buildings. That needed to be remediated. Obviously, that would have to be considered and included as part of the expenditures for the new building.
Those activities were undertaken by the National Capital Commission as part of getting the site ready in order to be able to do the construction.
