They’re called nail laminated timber panels, NLT for short, and they helped make some construction history on Monday.
That’s when crews began laying the wooden panels on the cage of posts and beams at the Minneapolis site of what will eventually be the seven-story office building known as T3 (Timber, Technology and Transit). When it’s finished sometime in this fall, the building will be the first modern tall wood building in the United States.
Not everything in T3 — which was designed by Vancouver's Michael Green Architecture and Minneapolis' DLR Group and is being developed by the Houston-based Hines — will be made of wood, of course. The elevator core as well as the parking level and foundation of the structure, which sits across the rail lines from the Designers Guild Building and behind Dock Street Landing in the city’s North Loop neighborhood, are concrete. But atop that deck are large glue-laminated timber posts and beams that will be covered by the NLT panels to form the flooring and ceilings of the office building.
