Perini Corporation

Under the direction of Bonfiglio's grandson, Lou Perini, the company moved into the real-estate business, developing|4500 acres in Palm Beach County, Florida. Later real-estate ventures were less successful, leaving Perini deeply in debt by the mid-1990s.

Controversies

In 2002, the firm and the City of San Francisco had a dispute over cost overruns, which settled in 2006 for $19 million with neither side admitting fault; the firm has continued to work on projects in San Francisco.

In March 2011, a jury in Brooklyn found Zohrab B. Marashlian, a former executive of Perini Corp.’s Civil Division, guilty of fraud in connection with construction projects. The judgment was vacated in April 2011 due to Marashalian's death prior to the completion of proceedings.

In In 2018, Tutor Perini and a subcontractor were alleged to have installed standard-strength train rails rather than high-strength rails requested by a San Francisco construction contract. Tutor Perini argued that they were in "full compliance" with the contract specification, as the city requested the special rails only for certain segments of track, such as tight turns. Emails suggested the city knew about the installation of "standard" rails as early as 2015. The city later stated "it is not a safety issue we’re concerned about" but rather about the longevity of the rails. The rails were replaced without incident.

In 2025, a lawsuit regarding the construction of a hotel in Philadelphia was advanced to the damages phase to determine the impact of a construction delay related to concrete flooring. In 2026 Tutor Perini was ordered to pay $174,400,000 for the delays, costs and interest, including $31,000,000 in damages.
