T. Burke Hayes, 95, a founder of the international engineering firm CH2M Hill, one of the companies awarded controversial cleanup contracts after Hurricane Katrina, has died.

Mr. Burke died at his home in Oregon on Friday, according to the company.

The firm was founded in 1946 in Corvallis, Ore., as CH2M.

Later, it merged with Clair A. Hill and Associates to become CH2M Hill. Now headquartered in Denver, the firm specializes in water treatment, hazardous-waste cleanup and industrial design.

It was among several large, politically connected firms awarded lucrative no-bid cleanup contracts in the immediate aftermath of Katrina.

The company has 19,000 employees, and revenue in 2006 was $4.5 billion, according to its Web site.
