Over the past two years, our San Francisco office has partnered with Cristo Rey Network, a high school whose students work at WJE year-round, and the results have been gratifying for both the students and our company. https://ow.ly/VB4k50SIJYJ

To celebrate National Intern Day, our Chicago-area interns spent the day at our Northbrook (IL) headquarters campus. They toured our Janney Technical Center laboratories and participated in the "Ask the Structure Experience" (a hands-on, experiential showcase of our technical and testing capabilities and in-house research projects).

Happy National Intern Day! An enthusiastic thank you to our seventy-six interns who've immersed themselves in the WJE experience this summer, working side-by-side with our gurus, recent grads, and everyone in between. We're happy to share our expertise and passion for our work with the next generation of talented young professionals. #buildingblocks #nationalinternday

Metallurgy staff in our Janney Technical Center perform testing to determine the thickness and quality of the protective coating on a sample and to evaluate conformance of zinc or zinc-alloy coatings on iron and steel products using ASTM A90, Test Method for the Weight of Coating on Iron and Steel Articles with Zinc or Zinc-Alloy Coatings. The work involves initial weighing of the sample, followed by stripping the coating from the substrate, usually by chemical or electrolytic means, and then accurately measuring the weight loss that ensued. ASTM A90 provides sampling and testing procedures for zinc-coated sheet metal, zinc-coated wire, and zinc-coated articles other than sheet or wire. In general, a sample needs to be at least 2.25 inches square, as the standard requires this size to conduct the testing. More about our solutions: https://ow.ly/MQWZ50SCMu9

Missed our recent webinar on post-tensioned buildings? Engineers Timothy Gregor, S.E., P. E., Ralf Leistikow, and Tracy Naso explain what post-tensioning systems are, review indicators that these systems are not performing as intended, and describe various approaches to maintain and repair them. Viewers are eligible for 1 HSW Learning Unit. Learn more and register now: https://ow.ly/hlCL50Ss8my

This past spring, Daniel J. Lemieux, FAIA NCARB RIBA MRICS with the support of fellow members of the Georgia Institute of Technology School of Civil & Environmental Engineering CISE and Building Construction Advisory Boards, helped develop and lead a first-of-its-kind course called "Solving for ‘Why?’: Failures and Forensics in Our Built Environment." This three-credit course welcomed graduate and undergraduate students from the Georgia Tech School of Architecture, Georgia Tech College of Engineering, and Georgia Tech School of Building Construction and featured subject matter experts who investigated some of the most significant building failures of the past fifty years, from the Kansas City Hyatt Skywalk collapse over forty years ago to the more recent tragedy at Champlain Towers. For their term project, students selected a building or structural failure of interest to them, researched that failure, then interviewed the subject matter experts responsible for that investigation before preparing a final report and presentation to a jury of educators and practicing professionals. One student noted: "This has definitely been one of the most informative classes I've taken at Georgia Tech so far.” Special thanks to our students, Dr. Ece Erdogmus, PE, and Dr. Fred Meyer, PE for helping to make this course and lecture series a success. Thanks also to our colleagues, friends, educators, and practicing professionals at Georgia Institute of Technology; Wiss, Janney, Elstner Associates, Inc.; Simpson Gumpertz & Heger (SGH); RDH Building Science; Atkinson-Noland & Associates; and Degenkolb Engineers.

Power of Microscopy || Value of Petrography 63 I’d like to share images of secondary deposits in air voids of concrete and invite you to discuss how these deposits may (or may not) compromise the air-void system functionality. Air voids can be filled by secondary deposits, which may range from a thin layer to fully filled, packed either loosely or densely, consisting of ettringite, calcium hydroxide, carbonate, or a mixture of these. Please focus on: 1. The role and in-depth mechanisms of air void systems in mitigating cyclic freeze-thaw damage. 2. Whether and how secondary deposits in air voids affect their performance in freeze-thaw mitigation. If you have done recent research or know of good articles on this topic, please also provide full references. I'd love to hear your insights and experiences! (Notes: most circular features in these images are air voids; there are dozens of voids in a few images. They can be white, black, colorless, or colorful, depending on the lighting conditions and imaging modes.)
