"I look forward to working with Balfour Beatty management to make PB the leading professional services firm in our industry."

Mr. Hawksworth has been with PB for 33 years. He was named CEO in January, 2008 and led a two-year strategic planning process that resulted in a merger with Balfour Beatty that was approved by 99 percent of PB's stockholders in October, 2009. "Having achieved the strategic objective of a larger, more diversified company that has the resources to remain competitive going forward, I believe the time is right for me to turn the management of the company over to George" he said.

Mr. Hawksworth succeeds James L. Lammie as PB's Chairman.
