Glulam falls down (possibly literally) in the jointing. The whole point of using green oak is that the joints tighten up as the wood seasons in the building, reducing to neglibility the need for joint maintenance. The system works, as can be seen in the large number of buildings that are approaching a millenium in age. In contrast, the oldest glulam building is not even 200 years old. The biggest argument against it, however, is that it wasn't done that way when ND was constructed.
