U.S.-Based Firm in Architectural Venture: RTKL Associates Inc. said it was selected in a joint venture with two Japanese architectural firms to design for the government a $500-million, 2.7 million-square-foot office complex in a Tokyo suburb. The company, with offices in Los Angeles, said the contract results from intensive efforts by the U.S. government to open the Japanese construction market to U.S. participation.
