In the search for sustainable building solutions, concrete floor slabs are a key challenge due to their high carbon footprint. Harnessing digital fabrication tools, a research team has explored a novel 3D printed plastic formwork to produce optimised ribbed floor slabs in an efficient manner. The new approach uses 40 percent less concrete, while offering the same structural performance. Credit: ETH Zürich #3dprinting #research #engineering | Wevolver.com

Hey, just a reminder about the Burdick Expressway bridge closure later tonight. The bridge will be closed to traffic at 8 p.m. tonight until 6 a.m. tomorrow morning, and again on Tuesday night at 8 p.m. to 6 a.m. the following morning. Crews will be foam jacking the approach slabs. Work will be done on the west end of the bridge one night, and on the east end the other night. There’s an easy way around the construction zone for those two nights: Take Valley Street and then 9th Street SE to get b
