The first question was on how many halls and hangars we have. We have three sites for construction in Halifax. Two of them are in Dartmouth, and they're focused on steel fabrication. Those parts are brought across the harbour into our main construction hall, which has two areas: an assembly hall and a module hall. Then the completed large modules go out onto the land level.
That is roughly how the construction process works at Irving Shipbuilding. It was designed with the assistance of a lot of international experts about 10 years ago.
The other questions were related to steel. I'm sorry, could you please repeat those?
