0:00 - The ceilings are going to be exposed.
0:02 - Nice.
0:03 - Wow.
0:04 - I am overjoyed, having worked so long teaching architects,
0:07 - engineers, and builders how to build large-scale structures
0:11 - out of wood, always pointing to precedent in Europe
0:14 - and in Canada.
0:15 - And now UMass is leading the way in how
0:18 - to create beautiful structures like the Design Building.
0:21 - The columns, the beams, the floors,
0:24 - they're all made out of a new type of wood
0:27 - called cross-laminated timber and glulam.
0:29 - And they're intentionally engineered
0:31 - to replace steel I-beams and concrete slabs.
0:35 - Seeing the structure go up, we blink and a column is up,
0:38 - and everybody seems to be happy on the site.
0:41 - We've actually seen people hugging columns already
0:44 - and so that's a special thing.
0:46 - There are a lot of technologically advanced ideas
0:49 - used in this building.
0:51 - We have concrete connected to the wood
0:53 - floors through a pulled steel mesh.
0:56 - We helped develop that connector here at UMass.
0:58 - And by doing that, you almost quadruple the stiffness,
1:02 - so it feels very rigid.
1:03 - And we have 1/8 inch tolerance for the pins
1:07 - to fit through the holes from a wood
1:09 - to steel interface, which is astounding.
1:12 - Eventually, we get a facade on the building, but not to worry,
1:15 - all of that wood will remain exposed on the inside
1:18 - so you can walk up to it and you can touch it.
1:21 - It is a demonstration structure to show the right way
1:24 - to design sustainably with wood, so I'm very excited.
