San Francisco, January 23, 2008—Bechtel Infrastructure Corporation and Parsons Brinckerhoff today reached an agreement that settles claims by the Commonwealth of Massachusetts and the U.S. Attorney for the District of Massachusetts regarding our work as management consultant for the Boston Central Artery/Tunnel project, also known as the Big Dig.

John MacDonald, chairman of the Bechtel/Parsons Brinckerhoff (B/PB) joint venture, issued the following statement:

"We have reached a full and final settlement of claims by the Commonwealth of Massachusetts and the U.S. Attorney for the District of Massachusetts. Protracted legal proceedings would have served no one well, and we believe that this resolution is in the interests of all concerned.

"We have always said that we take responsibility for our work. We understand and acknowledge with this resolution that our performance did not meet our commitment to the public or our own expectations. Above all, we deeply regret the tragic death of Milena Del Valle in the I-90 tunnel.

"Our companies have a long history of delivering safe, high-quality engineering and construction services. Our willingness to scrutinize our own performance and learn from experience has been a major factor in our success. Going forward, we will implement a number of specific measures to apply lessons learned to our future work, such as improving quality management systems, more-extensive and mandatory training for field engineers, and additional standardized specifications for design and construction.

"The Boston Central Artery/Tunnel project remains one of this country's most remarkable infrastructure achievements. It will serve the people of Massachusetts well into the next century."

Under the terms of the agreement, Bechtel Infrastructure Corporation (BINFRA) will contribute $352 million toward the settlement, with Parsons Brinckerhoff (PB) contributing $47,230,500, which includes funds intended for future repairs and nonroutine maintenance of the Central Artery/Tunnel. Both BINFRA and PB will take specific actions to enhance their existing training, compliance, and quality assurance programs in order to improve long-term performance and ensure that future work benefits from lessons learned during the Central Artery/Tunnel project. The agreement also provides remedies in the unlikely event of a future major incident for which B/PB is liable.
