Bruce Suprenant, Technical Director, The Voice Newsletter, December 2020

You might not have met Jim yet, but you will. He has been assisting ASCC on developing company certification, especially related to the company certifications. And he is also involved in ACI committees for ASCC including: ACI 318A-General Concrete and Construction, ACI 134-Concrete Constructability and ACI/ASCC 117-Tolerances. Now Jim will also be answering the ASCC concrete construction hotline calls (800-331-0668) and emails (, taking over for me after 4 years. I took over from the King of the Hotline, Ward Malisch, who had answered it for almost 30 years.

Jim has a unique background with a Masters in Structural Engineering from the University of Maryland and involvement in both engineering and construction of concrete structures for more than 40 years. Jim started work with Miller & Long in Maryland, then moved on to KCE Structural Engineers in Washington, D.C., and off to California to work for Martin, Middlebrook & Associates that changed to Martin, Middlebrook & Louie, and then to John A. Martin & Associates, and finally spending almost 30 years at the Conco Companies, from where he recently retired.

Jim has spent time as a construction administrator, quality control manager, project engineer, estimator, and project manager. His experience includes parking lots, parking garages, hotels, BART facilities, office buildings, apartment and condominium buildings, podium structures, the Oakland Bay Bridge, university facilities, stadiums, and the Salesforce Tower. Jim also has considerable shotcrete experience on basement walls.

Jim is a member of the American Concrete Institute (ACI) and the American Society of Civil Engineers (ASCE). He is the co-author of three ACI publications including “Constructability of Embedded Steel Plates in Cast-in-Place Concrete”, which received the ACI Construction Practice Award in 2019. He is also published in ASCE, being a co-author of “Performance of Jointless Bridges” in the ASCE Journal of Performance of Constructed Facilities, 1988.
Jim looks forward to the questions that might arise on the ASCC concrete construction hotline. We hope you challenge him.
