That's a very good question. When the fire tests are conducted at NRC, for example, even though the building, when it's built six storeys and above, is required to have sprinkler systems, we don't conduct our test with sprinkler systems. We're already assuming there is no sprinkler protection in that building. We're testing it, and it's withstanding two, three, or four hours depending on what we're testing it for. It withstands that fire for that duration of time.
The sprinkler system is just an added benefit. It's an additional precautionary measure to keep the fire from starting. Let's assume the sprinkler fails, and the fire has started. We still have other measures in that building to protect us. There are multiple redundancies built into this system.
If I can go back to the six-storey building, the National Building Code used to allow four storeys. You can build a four-storey, stick-timber construction with no sprinklers, and it is no problem, you were fine. We went to six storeys. We went with mass timber. We went with sprinklers. We went with wider corridors, less flame fed. We built the Cadillac version for six storeys, which is actually safer than the four-storey building.
That's the premise we're taking with the 12-storey building. We built in multiple redundancies because we want it very safe. We don't want people getting injured or firefighters getting injured in the building. As it starts getting built and we have more data, we start ratcheting back, or we start adjusting those requirements as we go forward.
