From a $690 vault to a $44 billion project backlog

In short: In 1902, Henry Turner started with just $25,000 and a single small contract. Today, the Turner Construction Company is a global powerhouse, managing massive infrastructure projects, from the United Nations Secretariat Building to the cutting-scale data centers driving the modern digital economy.

The trajectory of Turner Construction is a study in industrial evolution. Founded in 1902 by Henry Chandlee Turner in New York City, the firm's early success was built on technical pivots. A notable early win involved persuading a client, Robert Gair, to swap steel for concrete for subway staircases—a move that helped establish the company's reputation for large-scale reinforced concrete work.

Throughout the 20th century, the company expanded from local New York projects to a global presence. While the Great Depression saw revenues plummet from nearly $44 million to $2.5 million by 1933, the firm recovered, eventually diversifying into sports stadiums, medical centers, and government facilities. The 1999 acquisition by the German firm Hochtief further expanded its reach into the United Kingdom and Australia.

Modern growth is increasingly driven by the digital and biological sectors. By the end of 2025, approximately 40% of the company's $44.3 billion backlog was comprised of semiconductor plants, biopharmaceutical sites, and data centers. In fact, data center projects alone accounted for about 37% of the year-end backlog, with revenue in that sector more than doubling during the first nine months of 2025.

However, this scale has not been without controversy. The company has faced legal scrutiny, including a multi-year bribery and bid-rigging investigation involving Bloomberg L.P. projects, which led to a guilty plea from former vice president Ronald Olson in 2020. The firm has also navigated significant safety challenges, including a fatal structural collapse during a luxury apartment build in Cincinnati in 2019.
