Gerald A. “Gerry” Rauenhorst, 86, a design-build pioneer and founder of The Opus Group, which became one of the largest U.S. builder-developers before being hit by financial troubles in the recession, died on April 24 in Edina, Minn., after a long illness.
Rauenhorst, a civil engineer, launched an eponymous construction company in 1953 that later become The Opus Group, a Minneapolis-based commercial real estate developer that provides turnkey A/E/C services through three subsidiaries in nine U.S. offices.
