"in recognition of his unsurpassed leadership and dedication to the Institute, and for his unstinting gifts of time, talent, and expertise"

George C. Hoff is President of Hoff Consulting, LLC, Clinton, MS. He has over 40 years' experience working with concrete materials and structures.

An ACI member since 1962, Hoff became a Fellow in 1976 and has received the Henry L. Kennedy Award, 1983; the Wason Medal for Materials Research, 1984; the Chapter Activities Award, 1987; the Wason Medal for Most Meritorious Paper, 1994; and the Cedric Willson Award, 1995.

Hoff is the founder, first president, and a current member of ACI's Mid-South Chapter and Managing Director of the Concrete Innovations Appraisal Service (CIAS) of the Strategic Development Council (SDC) of ConREF. Currently, he is a member of ACI Committees 223, Shrinkage-Compensating Concrete; 335, Composite and Hybrid Structures; 357, Offshore and Marine Concrete Structures; 523, Cellular Concrete; 544, Fiber Reinforced Concrete; and 548, Polymers in Concrete. Other memberships include the Reinforced Concrete Research Council (RCRC); the Technical Activities Committee's High-Performance Concrete Committee, the International Conference Steering Committee, and the ISO TC-71 Advisory Committee. He is a Past President of ACI (1993-1994) and a past member of the Board of Direction.

Hoff received a BS degree in civil engineering in 1961, an MS degree in theoretical and applied mechanics in 1968 from the University of Illinois at Urbana-Champaign, and a PhD in civil engineering in 1981 from Texas A&M University, College Station, TX. He has been a registered professional engineer in the State of Mississippi since 1965.

George F. Leyh

"in recognition of his many years of leadership as Executive Vice President during which he stabilized the financial foundation of the Institute and promoted new directions for the membership"

George F. Leyh, ACI's former Executive Vice President, retired in 1998 after nearly 23 years in the position. Some highlights of Leyh's tenure at ACI include the implementation of Long-Range Planning (now Strategic Planning); expansion of technical and educational activities; and the initiation of a series of ACI certification programs aimed at improving construction quality. He also supervised the launch of Concrete International in 1979 and the pioneering of two separate ACI Journals - the ACI Structural Journal and the ACI Materials Journal. After a successful fundraising effort, a new ACI headquarters building was constructed in Farmington Hills, MI, and dedicated in 1996.

Under Leyh's direction, ACI increased its focus on international activities, with the Institute assuming the secretariat position of ISO Committee TC-71 on concrete. Leyh served as Chairman of this committee until his retirement. The Concrete Research and Development Council (ConREF) was also established to further the Institute's efforts in research and education, and Leyh was instrumental in the formation of the Strategic Development Council (SDC) under ConREF to encourage practical research within the concrete industry.

As the Institute's chief staff officer, Leyh was an Ex-Officio Member of both the Board of Direction and the Executive Committee. He also served as President of ConREF and ACI's for-profit subsidiary, Association Concepts Ltd., which was created to provide management services to other organizations. Until recently, he served on the Board of the American National Standards Institute (ANSI) and the American Society for Concrete Construction (ASCC).

Prior to becoming an ACI staff member, Leyh served as member and Chairman to various ACI technical committees, including Committee 318, Structural Concrete Building Code. An ACI Fellow, Leyh received the Delmar L. Bloem Distinguished Service Award in 1972 for his contributions on Committee 318 and other ACI committees, and the Henry C. Turner Medal in 2000 "for his leadership in administration and technical activities of ACI over many years."

A native of upstate New York, he received his BCE and MS in structural engineering from Cornell University, Ithaca, NY. His career history prior to joining ACI includes work with engineering firms in Syracuse, NY, and Chicago, IL; the Portland Cement Association; and the Concrete Reinforcing Steel Institute.

Bertold E. Weinberg

"for his long and dedicated service to the Institute and with special recognition of his outstanding efforts supporting and expanding the scholarship program"

Bertold E. Weinberg, retired, has 44 years' experience as a structural and construction engineer. He has worked for engineering firms, contractors, developers, and government agencies in Albany and Delmar, NY; Pittsburgh, PA;and Chicago, IL. He was involved in the design and construction of numerous facilities, including Marina City (1959-1963), which were the world's tallest concrete buildings at that time (588 ft.). For the Dormitory Authority of the State of New York, he was responsible for the rehabilitation of dormitories on 29 state university campuses. In addition, he formulated and implemented agency-wide policies that impacted the design and construction of all of the agency's various structures.

After fleeing Nazi Germany, Weinberg came to the U.S. in 1940. He served in the military in World War II and retired as a Colonel from the Army Reserve, Corps of Engineers, in 1981.

He is currently Chairman of the Scholarship Council and ACI Committee C 630, Construction Inspector Certification. He is also a member and former Chairman of ACI Committees 311, Inspection of Concrete; 362, Parking Structures; C 620, Laboratory Technician Certification; C 630-T, Concrete Transportation Construction Inspector Certification; the Responsibility in Concrete Construction Committee; and is a Trustee of the Concrete Research and Education Foundation (ConREF). He has served on the ACI Board of Direction, the Financial Advisory Committee (FAC), and the Certification Programs Committee, and is a past member and Chairman of Committee 348, Structural Safety, and Past President of ACI's Eastern New York Chapter. In 1977, he was awarded the Henry L. Kennedy Award.

Weinberg received his BCE from Rensselaer Polytechnic Institute in Troy, NY, and his Master of Public Administration from the State University of New York in Albany.
