David Barber, principal for Arup, presented “Fire Safety and Code Challenges for Mass Timber in Curtain Wall Systems: Negotiating Codes for a Sustainable Design,” on behalf of his co-authors, HOK senior associate John Neary and FTI ambassador of innovation and collaboration Mic [more]
As labor shortages hang over the construction industry, suppliers and contractors ponder how they might use the latest technologies to replace human functions. Five years ago, around 20% of builders reported they had begun to tinker with technologies such as drones and 3D printers. Since then, robots have surfaced doing everything from installing studs, drywall and tile to laying bricks at a rate of 1,000 per hour. Now, engineers at Carnegie Mellon University are taking [more]
Ronald Olson, a former vice president and deputy operation manager for Turner Construction Co., pleaded guilty to charges of evading taxes on more than $1.5 million in bribes he received from subcontractors in exchange for being awarded contracts for Bloomberg projects.

Safety, security and acoustic performance—all are benefits of laminated glass. But what happens when someone in hurricane-prone Miami, for example, in a busy high-rise neighborhood, wants glazing that combines sound control with the required hurricane performance? That’s somewhat of a challenge, according to Steve Bennison, a technology fellow with Kuraray, who discussed a new laminated glass technology for combining both hurricane and acoustic glazing technologies. Bennison explained that the polymer requirements are different for each [more]
The U.S. has reimposed a 10% tariff on non-alloyed unwrought aluminum imported from Canada, citing a substantial increase in imports over the period from June 2019 through May 2020. The tariff will take effect August 16, 2020.

The Facade Tectonics Institute’s 2020 World Congress began this week with paper presentations from glass industry experts from around the world. Paper presentations are split into different topic groupings.
In the European Façade Network: Safety and Structure group, professor Jens Schneider with the Technical University Darmstadt, presented his paper, “Innovations With Glass.” Schneider explored various projects in which glass has pushed the limits of design in the past 15 years, such as the glass boxes at [more]
