Arthur F. Hintze, 64, a former government attorney who was an official of the Associated General Contractors of America, died Saturday at Suburban Hospital after a heart attack.
He had been the A.G.C.A.'s director of government relations and open shop services since joining the trade organization 25 years ago.
Mr. Hintze was a native of Falls, Pa., and came to Washington in 1938 to work as a technician for the F.B.I. and to attend George Washington University's law school.
From 1943 to 1951 he was an attorney with the Labor Department, then joined the U.S. Chamber of Commerce where he worked until joining the A.G.C.A.
Mr. Hintze was a member of the District of Columbia and U.S. Supreme Court bars. He and his wife, Hilda, were residents of Bethesda.
In addition to his wife, he is survivied by a daughter, Judy Hintze of Glenwood, Fla.; two sons, Ronald, of Honolulu, and George, of Nichols, N.Y.; a sister, Helen Beyrent of Falls, Pa., and seven grandchildren.
The family suggests that expressions of sympathy be in the form of contributions to the Duvall Home for Retarded Children in Glenwood, Fla., or the Montgomery County Association for Retarded Citizens.
