President
Jeffrey Coleman
Jeffrey W. Coleman, FACI, is a licensed professional engineer, Attorney at Law, and Principal Partner of The Coleman Law Firm, LLC, Minneapolis, MN. He is a Fellow of ACI and has been an ACI member for 40 years. Coleman is the author of the book Legal Issues in Concrete Construction, published by ACI in 2004 (second edition published in 2014), and previously authored the “Concrete Legal Notes” section of Concrete International.
Coleman received both his BS in civil engineering in 1976 and MS in structural engineering in 1977 from Iowa State University, Ames, IA. He is also licensed as an engineer in Iowa, Minnesota, and Wisconsin. He is also licensed as a lawyer in Minnesota, Wisconsin, Iowa, and North Dakota. However, he practices regularly in other states through admission “Pro Hac Vice.” His master’s degree thesis work involved research funded by the Iowa Department of Transportation and studied fatigue behavior of air-entrained concrete. This led to his early involvement with ACI Committee 215, Fatigue of Concrete.
Coleman served as a member of the ACI Board of Direction from 2012-2015 and has served as a member of ACI Committee 301, Specifications for Structural Concrete. He has also served as a member of the ACI Construction Liaison Committee, TAC Specifications Committee, Financial Advisory Committee, and Conventions Committee and was Chair of the Responsibility in Concrete Construction Committee (now ACI Committee 132), where he continues as a member.
Additional accolades
After receiving his master’s degree in structural engineering, Coleman moved to Minneapolis/St. Paul, where he practiced as a Structural Engineer with Ellerbe Associates, Inc. After completing his law degree in 1984, Coleman served as general counsel for Ellerbe, Inc. (later Ellerbe Becket, Inc. and now part of AECOM). After spending 2 years with a Minneapolis-based boutique construction law firm, he started his own firm in 1991, which was quickly merged and renamed Coleman, Hull & van Vliet, PLLP. In 2013, he founded The Coleman Law Firm, LLC—committed to continuing his representation of engineers, architects, and the concrete construction industry, including concrete contractors and suppliers.
Coleman represents engineers, architects, concrete contractors and suppliers, and building owners in all aspects of construction. He is consistently recognized as a construction “Super Lawyer” by Thomson Reuters publications. Coleman is the Past President of the Minnesota Concrete Council (MCC) and a former Board member.
