A construction company whose projects included the stadium where the New York Mets play and the Sept. 11 Memorial agreed to pay up to $56 million in penalties and restitution after admitting a decade-long fraud that included routinely overcharging customers and ignoring minority hiring mandates, authorities announced Tuesday.

A deferred prosecution agreement in U.S. District Court in Brooklyn described the penalty and restitution to be paid by Lend Lease U.S. Construction, a division of an international company that employed more than 1,000 workers during the 10-year stretch from 1999 through 2009.
