Milani served as Manager of the DMJM construction management division, Technical Management Services, Incorporated. IIn 1984, Ashland Oil, Incorporated, of Covington, KY, purchased DMJM and held it for six years. It sold the company back to its employees, who formed the firm AECOM in 1990. AECOM grew dramatically by further acquisitions and, because of its now far-flung construction, construction management, and engineering operations reorganized its subsidiaries in 2000. Portions of DMJM became parts of two AECOM companies: DMJMH Harris and DMJM Holmes and Narver. DMJM Harris became based in New York, NY, with several West Coast branch offices, focused on transportation and infrastructure design and construction projects. DMJM Holmes and Narver remained based in Los Angeles, and had a general design focus working for mainly institutional, corporate and governmental clients. In 2006, AECOM had 1,171 employees in its DMJM-branded subsidiaries.
