Committee C15 on Manufactured Masonry Units presented the 2004 Alan H. Yorkdale Award to Jeff Greenwald, P.E.; Dennis W. Graber, P.E.; and Marcus Cherundolo for their paper, "Research Evaluation of Single Lift Grouting in Concrete Masonry Wall Panels." Committee C15 established the award in 1987 to recognize the author or authors of the best paper each year concerning clay shale, concrete, or sand-lime masonry.

The coauthors work for the National Concrete Masonry Association (NCMA) in Herndon, Va., where Greenwald, who lives in Annandale, Va., is vice president of research and development; Graber, who lives in Haymarket, Va., is director of technical publications; and Cherundolo, who lives in Reston, Va., is a research engineer.

Greenwald, an ASTM International member since 1996, works on Committees A01 on Steel, Stainless Steel and Related Alloys, C12 on Mortars and Grouts for Unit Masonry, C15, E05 on Fire Standards, and F33 on Detention and Correctional Facilities, and he is chair of C12.07 on Laboratory Accreditation and C15.07 on Standards for Laboratory Accreditation. Outside ASTM International, Greenwald is a member of the American Society of Civil Engineers, the Masonry Society, and the National Society of Professional Engineers.

In his position at NCMA, Greenwald focuses on structural engineering and masonry design and testing. He joined the NCMA staff in 1995 as director of codes and standards and assumed his current position in 2001. Greenwald is a graduate of the University of Maine with a B.S.C.E. in structural engineering, and he holds an M.C.E. in civil engineering from the University of Delaware.

Marcus Cherundolo, who joined the staff of NCMA in January 2004, does research and development of concrete masonry systems for the organization. A member of the American Society of Civil Engineers and the Masonry Society, Cherundolo has previous experience in highway and bridge construction as an estimator and as a construction inspector. Cherundolo earned his B.S. in civil engineering and his M.S. in structural engineering from the Virginia Polytechnic Institute and State University in Blacksburg.

A former first lieutenant in the U.S. Army Corps of Engineers, Graber worked as a project engineer with various consultants and as a structural field engineer for the Portland Cement Association in Florida, then as director of engineering for the Florida Concrete and Products Association in Orlando, Fla., before assuming his position at NCMA in 1998. In his career, he has focused on civil engineering with a structural specialty. Graber graduated from Freeman Junior College, Freeman, S.D., with an A.A. in pre-engineering and earned his B.S. in civil engineering from the South Dakota State University at Brookings.
