History

A.G. Tutor Company, Inc

In 1949, Albert G. Tutor launched a family construction business, A.G. Tutor Company, Inc. His son Ronald joined the company in 1963, and the company expanded under his leadership. In 1972, the company partnered with N.M. Saliba. In 1981, Ron Tutor took the reins as president of the Tutor-Saliba Corporation.

Perini Corporation

Perini Corporation was founded in 1894 in Ashland, Massachusetts by a stonemason named Bonfiglio Perini. The company grew to become one of the region's most recognized heavy construction contractors. From 1931 to 2009, Perini was headquartered in Framingham, Massachusetts.

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.

Tutor Perini Corporation

In 1997, Ron Tutor helped Perini Corp. recapitalize alongside investor Richard Blum. Tutor became CEO of Perini in 2000 and merged Perini with Tutor-Saliba in 2008 in a transaction valued at $862 million.

Perini was originally listed OTC on June 15, 1961, then subsequently listed on AMEX on May 12, 1970, then listed on the NYSE on April 1, 2004. It was headquartered in Framingham, Massachusetts until relocating to Sylmar, California in 2009.

In May 2009, Perini shareholders voted to change the company's name to Tutor Perini Corporation.

Notable projects

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.
