OIG investigation leads to bribery charges against owner & president of masonry contractor

March 28, 2025

PHILADELPHIA — The president and sole owner of a masonry restoration contractor hired by Amtrak for façade restoration and repair at 30th Street Station was charged Thursday with conspiracy to commit federal program bribery and making and presenting a false claim, according to the U.S. Attorney’s Office, Eastern District of Pennsylvania.

According to court documents, Mark Snedden, 69, of Munster, Indiana, allegedly conspired with Lee Maniatis, Khaled Dallo, and Donald Seefeldt—vice presidents with Snedden’s company—to bribe an Amtrak project manager with approximately $323,686 worth of paid vacations, jewelry, cash, dinners, entertainment, transportation, and other items of value. In exchange, the former project manager approved over $52 million in additional change orders and contract modifications and provided the contractor with internal information about the project.

Maniatis, Dallo, and Seefeldt were previously charged for their alleged participation in the scheme, and Seefeldt pleaded guilty to conspiracy to commit federal program bribery last month. All three men were suspended by the Federal Railroad Administration from participating in all federal funded procurement and non-procurement programs and activities.
As a result of the scheme, Amtrak was overbilled by more than $2 million for completion of the repair and restoration work.
Federal funding supplied 90 percent of the money Amtrak used to pay the contractor for the façade project, the U.S. Attorney’s Office said in its release.

In addition to Amtrak’s Office of Inspector General, the case was investigated by the FBI and the U.S. Department of Transportation OIG. United States Attorney Jason Grenell is prosecuting the case.
