Two AECOM engineers receive Lifetime Achievement Awards from ASCE.

American Society of Civil Engineers honors AECOM President and CEO John M. Dionisio and geotechnical expert Clyde N. Baker at gala event in Washington, D.C.

LOS ANGELES -- AECOM Technology Corporation (NYSE: ACM), a leading provider of professional technical and management support services for government and commercial clients around the world, announced today that AECOM President and Chief Executive Officer John M. Dionisio, P.E., and geotechnical engineer Clyde N. Baker, Jr., P.E., received Lifetime Achievement Awards from the American Society of Civil Engineers (ASCE) as part of the society's Outstanding Projects and Leaders (OPAL) program at an awards dinner in Washington, D.C., last night.

Dionisio received the Lifetime Achievement Award in Management, and Baker received the Lifetime Achievement Award in Design.

The OPAL Lifetime Achievement Award program was established in 1999 to recognize and honor outstanding civil engineering leaders whose lifetime accomplishments have made significant differences in the world. Dionisio and Baker are the second and third AECOM professionals to win this prestigious award. AECOM's founding chairman, Albert A. Dorman, P.E., received the Lifetime Achievement Award in Management in 2000.

In addition to AECOM's two Lifetime Achievement Award honorees, one of the company's projects was a finalist for the ASCE's Outstanding Civil Engineering Achievement (OCEA) award.

The Pasadena City Hall Seismic Upgrade and Rehabilitation Project in Pasadena, Calif., for which AECOM served as the construction manager, was named an OCEA finalist based on the comprehensive program's state-of-the-art structural seismic upgrades, interior renovation and the application of new building technology. The $117-million project included the replacement of out-dated building systems and the use of new fire safety systems.

The OCEA award was established in 1960 to honor the project that best illustrates superior civil engineering skills and represents a significant contribution to civil engineering progress and society. Honoring an overall project, rather than an individual, the award recognizes the contributions of many engineers. AECOM has been part of the project teams of three previous OCEA award winners: Rion-Antirion Bridge, Corinthian Straits, Greece (2005); Glenwood Canyon Project, Glenwood Canyon, Colorado (1993); and Southwest Corridor Project, Boston, Massachusetts (1988).
