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, Apr 10, 2008 (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.
