On Wednesday, January 6, 2021, the U.S. Capitol building was the target of an attack that left it ransacked and vandalized. The destruction of many irreplaceable historical wooden artifacts and objects, including doors, intricate millwork, moldings, desks, and podiums, was extensive.
Engineering News-Record recently featured Forest Products Laboratory’s (FPL) materials research engineer, Laura Hasburgh and her expert consultation on the Ascent construction project in Milwaukee. At 25 stories, the Ascent building is making history as the soon-to-be tallest timber building in the world. And because of its unprecedented height and exposed mass timber interior, Hasburgh was contacted to lend her fire testing expertise.
The top eighteen floors of the Ascent will be framed in mass timber and the interior architectural design features exposed glued-laminated timber (glulam) framing and cross-laminated timber (CLT) slabs to showcase the natural beauty of the wood. But with these design and material choices, the Ascent’s fire safety planning needed to be carefully considered.
Forest Products Laboratory’s (FPL)Brian Brashaw was featured in an National Public Radio (NPR) segment about the soon-to-be world’s tallest timber building currently under construction in Milwaukee, Wisconsin. The Ascent building will boast 25 stories, 18 of which will be framed in mass timber. The upscale apartment complex is slated for completion in 2022. Right now, the cement foundation is being laid. Brashaw anticipates the Cross Laminated Timber (CLT) “to start flying,” or rather, construction crane hoisted pre-fabricated mass timber sections to begin installation in early summer 2021.
FPL is excited about its participation in helping the Ascent rise among the tallest modern wood structures in the world.
If you live in Wisconsin, chances are that you at least know of Eagle Tower. More likely, you—along with thousands of visitors from around the world—have had indelible experiences of taking in spectacular views of Lake Michigan, the surrounding islands, and Michigan’s Upper Peninsula. Eagle tower offered a captivating and much beloved panorama of Peninsula State Park.
Our nation’s bridges have been under an every-two-year mandated inspection for nearly 50 years. The current method of inspecting bridges is accomplished largely by visual assessment often using costly snooper trucks. Wacker describes this approach as “a passive approach that has provided subjective and unreliable data.”
