John F. Duntemann

Senior Principal


John Duntemann specializes in the assessment and repair of structural distress and serviceability problems in buildings, bridges, and other structures. In his forty-year career, he has performed a variety of consulting activities related to new and existing construction, including bridge and transportation structures, civic and commercial buildings, industrial buildings and facilities, stadiums and arenas, parking structures, storage tanks and temporary structures.

He has published more than forty papers and lectured extensively on the performance and assessment of structures, structural failures, structural rehabilitation, and design and construction codes and standards. He is a contributing author to the Handbook of Temporary Structures in Construction (1996, 2012) and the Forensic Structural Engineering Handbook (2000, 2010). He also authored a state-of-the-art standard, Guide Design Specification for Bridge Temporary Works (1995, 2015), adopted by the American Association of State Highway and Transportation Officials.

Mr. Duntemann is a Fellow of the Structural Engineering Institute (SEI) and International Association for Bridge and Structural Engineering (IABSE). He is past president of the Structural Engineering Association of Illinois (2013–2014) and served on the Illinois State Task Force on School Plan Review and Inspection (2006). He is also a former member of the National Council of Examiners for Engineering and Surveying Structural Exam Committee (2004–2010) and a member of the ASCE/SEI 7 Standards Committee, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, since 1995.
