AECOM's Clyde Baker Named Award of Excellence Recipient by ENR Magazine

Geotechnical engineer has worked on four of five current tallest
buildings in world and eight of 20 tallest on planet
LOS ANGELES--(Business Wire)--
AECOM Technology Corporation (NYSE: ACM), a leading provider of
professional technical and management support services for government
and commercial clients around the world, announced that Clyde N.
Baker, Jr., P.E., S.E., senior principal engineer, received the 2007
Award of Excellence by Engineering News-Record (ENR) at a ceremony in
New York last Thursday. Baker was chosen from a field of the Top 25
Newsmakers of 2007 for his innovations and achievements in the field
of geotechnical engineering, most notably increasing the allowable
bearing loads for large foundations.

Baker's project experience includes work on eight of the 20
current tallest buildings in the world, including four of the five
tallest: Taipei 101 in Taiwan, the two Petronas Towers in Kuala Lumpur
and the Sears Tower in Chicago. In addition, Baker has provided peer
review services on some of the tallest buildings under construction,
including the Burj Dubai in the United Arab Emirates and the Chicago
Spire in the United States, which may hold the record for the highest
bearing pressures in the world when completed.

"Today's skylines would not look the same without the important
work of Clyde Baker," said Janice Tuchman, ENR editor-in-chief.
"Considering the extreme pressures that these buildings place upon the
earth and Baker's role in raising allowable bearing loads, especially
in the Chicago area, we are proud to award him for his lifelong
contributions to the field, which have enabled the immense strides the
industry has taken in recent years."

"Clyde is a deserving recipient of ENR's award as he has made
significant contributions to the engineering industry through his
innovative foundation solutions over the past 50 years," said AECOM
President and CEO John M. Dionisio. "His expertise has made him one of
the preeminent geotechnical engineers in the world."

Baker has developed an international reputation in the design and
construction of deep foundations and has been a leader in using
in-situ testing techniques correlated with past building performance
to develop more efficient designs. He has also been instrumental in
increasing the use of the Menard Pressuremeter, which monitors the
relationship between pressure and deformation in soil, in the United
States.
