Overview
Tutor Perini Corporation is a publicly traded American construction contractor whose business spans major civil infrastructure, building construction, and specialty mechanical and electrical work. The company serves public agencies, institutional owners, developers, and other commercial customers, with capabilities covering the delivery of complex projects from preconstruction and estimating through construction, project management, commissioning, and maintenance. The company traces its corporate heritage to Perini Corporation, founded in 1894 in Ashland, Massachusetts, by stonemason Bonfiglio Perini. Perini developed into a substantial heavy-construction contractor in the northeastern United States and later expanded into real estate. Its real-estate activities, particularly in Florida, contributed to significant financial pressure by the mid-1990s. A restructuring and recapitalization involving Ron Tutor and investor Richard Blum helped stabilize the company. Tutor became Perini's chief executive in 2000. Tutor's own construction lineage began with A.G. Tutor Company, established in 1949 by Albert G. Tutor. Ronald Tutor joined the family enterprise in 1963 and later worked with N.M. Saliba, leading to the formation and growth of Tutor-Saliba Corporation. In 2008, Perini and Tutor-Saliba combined in a transaction valued at approximately $862 million, creating the business now known as Tutor Perini. Perini shareholders approved the name change in 2009, and the headquarters moved from Framingham, Massachusetts, to Sylmar, California. Tutor Perini's civil-infrastructure work includes bridges, highways, tunnels, airports, rail and mass-transit systems, and other transportation structures. Its building activities include healthcare, education, municipal and government facilities, detention facilities, hospitality and gaming properties, offices, high-technology facilities, mixed-use developments, and multi-unit residential towers. Specialty operations provide electrical, mechanical, plumbing, heating, ventilation, air-conditioning, fire-protection, structural-concrete, tunneling, drilling, and related services. The company expanded its geographic and technical reach through acquisitions and operating subsidiaries. These have included Florida contractor James A. Cummings, Cherry Hill Construction, Rudolph & Sletten, Desert Mechanical, Black Construction in Guam, Keating Building, Superior Gunite, Fisk Electric, Anderson Companies, Frontier-Kemper Constructors, Lunda Construction, GreenStar Services and its operating businesses, and Becho. The resulting portfolio combines large general-contracting operations with specialist contractors able to perform technically demanding work. Tutor Perini has pursued large and often publicly scrutinized projects, where contract scope, design changes, schedule delays, payment claims, and cost overruns can materially affect results. Disputes involving San Francisco infrastructure work and a Philadelphia hotel project, along with questions about rail specifications on a San Francisco transit project, illustrate the litigation and execution risks associated with complex construction. The company continues to operate as a U.S.-centered contractor with selected work in Guam, the Indo-Pacific region, and other international locations. Wikipedia reported approximately $5.54 billion in annual revenue for 2025; this figure should be read with its stated year and source context rather than as a timeless company valuation or sales estimate.
History
Tutor Perini's history combines two American construction lineages. Perini Corporation began in 1894 in Ashland, Massachusetts, where stonemason Bonfiglio Perini established a contracting business. It became a recognized heavy-construction company in the northeastern United States and was headquartered in Framingham, Massachusetts, for much of the twentieth century. Under Bonfiglio Perini's grandson Lou Perini, the business also entered real-estate development, including a large project in Palm Beach County, Florida. Later real-estate ventures were less successful and left Perini heavily indebted by the middle of the 1990s. The second lineage began in 1949, when Albert G. Tutor founded A.G. Tutor Company. His son Ronald joined in 1963. The Tutor organization expanded through a 1972 partnership with N.M. Saliba, and Ron Tutor became president of Tutor-Saliba Corporation in 1981. Tutor-Saliba developed experience in major building and infrastructure work and became the operating platform associated with Ron Tutor. In 1997, Ron Tutor participated with investor Richard Blum in the recapitalization of Perini. Tutor became Perini's chief executive in 2000, initiating a period in which the company returned its focus toward construction and expanded through acquisitions. Perini acquired James A. Cummings in 2003, followed by Cherry Hill Construction and Rudolph & Sletten in 2005. It added Desert Heating and Cooling, later renamed Desert Mechanical, in January 2008. The decisive corporate event came in 2008, when Perini merged with Tutor-Saliba in a transaction valued at approximately $862 million. Perini shareholders approved the Tutor Perini name in May 2009. The company also relocated its headquarters from Framingham to Sylmar, California, in 2009. Its public-market history predates the merger: Perini traded over the counter beginning in 1961, moved to the American Stock Exchange in 1970, and was listed on the New York Stock Exchange in 2004. Expansion continued after the merger. The company acquired Black Construction in Guam and Philadelphia-based Keating Building Corporation in 2009. In 2010 it acquired Superior Gunite, a structural-concrete specialist. During 2011 it added Fisk Electric, Anderson Companies, Frontier-Kemper Constructors, Lunda Construction Company, GreenStar Services and its operating businesses, and Becho. These transactions broadened the company from a general contractor into a group with significant electrical, mechanical, tunneling, drilling, bridge, railroad, structural-concrete, and specialty-construction capabilities. Tutor Perini's operating model is organized around civil, building, and specialty construction. Civil operations pursue transportation and other infrastructure projects, while building operations address institutional, commercial, residential, hospitality, government, and technology facilities. Specialty businesses supply trade contracting and technically complex services. This breadth allows the company to bid on large projects requiring multiple construction disciplines, but it also exposes the business to the contractual, scheduling, estimating, and claims risks common to complex fixed-price and public-sector work. The company has faced recurring disputes associated with major projects. A cost-overrun dispute with San Francisco settled in 2006 for $19 million without either side admitting fault. In 2011, former Perini civil-division executive Zohrab B. Marashlian was found guilty by a Brooklyn jury of fraud connected with construction projects; the judgment was subsequently vacated after his death before completion of the proceedings. In 2018, the company and a subcontractor were challenged over rail strength on a San Francisco project, with Tutor Perini maintaining that the installation complied with the contract. More recently, litigation over a Philadelphia hotel involved alleged delays tied to concrete flooring and proceeded to a damages determination. These matters demonstrate the importance of contract administration and project controls to the company's reputation and financial performance. Tutor Perini remains an active, U.S.-centered construction group headquartered in Sylmar. Its work extends across North America and includes Guam, the Indo-Pacific region, and selected overseas or international locations. Wikipedia reported approximately $5.54 billion in annual revenue for 2025, subject to the source's reporting period and the company's financial disclosures.
