Tribute to Roger S. Johnston

Mr. Johnston, a Nebraska native, was a graduate of the University of Nebraska, earning his degree in Civil Engineering. Roger was involved in the construction engineering industry for over 50 years, starting his career with Hensel Phelps, McNamara, and Kiewit. Mr. Johnston also held engineering management positions over the years with Aluma Systems, Patent Construction Systems, and Harsco Infrastructure. Roger retired from Harsco in 2012, ending his 13 year service as Director of Engineering. Mr. Johnston was a licensed civil engineer in several states, and was an American Concrete Institute (ACI) Fellow, serving as Member and Chairman of the ACI Committee 347: Formwork for Concrete, which is responsible for publishing the “SP-004: Formwork for Concrete” considered the definitive source for all things concrete formwork and falsework related. As an ASCE member, Roger also served as a member of the ASCE Standards Committee “Design Loads on Structures During Construction” which publishes ASCE Standard 37.

We want to pay tribute to Roger Johnston, not only for his many years of service and contribution to the Construction Engineering Industry, but also for the 8 years he generously gave to Crimson Engineering as a colleague and mentor. It was an honor to have him be a part of our team, and he will be deeply missed. Crimson Engineering is also honored to sponsor an undergraduate engineering scholarship in Roger's name through the ACI Foundation. CEA will match all scholarship donations up to $5,000 per year. Donations can be made directly to the fund through the ACI Foundation website.
