Turner Construction Company is one of the largest construction management companies in the United States, with a construction volume of $8 billion in 2010. It is a subsidiary of the German company Hochtief, which itself is a division of the Spanish construction company Grupo ACS.

Henry Chandlee Turner (b.1871) founded Turner Construction Company in 1902, with $25,000 in start-up capital, at 11 Broadway, New York City. Turner's first job was a $687 project; to build a concrete vault for Thrift Bank in Brooklyn. In 1903, a Scottish industrialist named Robert Gair, involved with the manufacture of paper products, hired Turner Construction to build a plant in Brooklyn. The facility, finished in 1904, measured 180,000 sq ft (17,000 m²), making it, at the time, the largest reinforced concrete building in the United States. At the same time the company was developing plans for the Gair building, Turner began building staircases for the New York City subway system. The original design showed the stairs were to be made of steel, but Turner thought concrete was a less expensive alternative. After examining public bidding records, Henry Turner undercut competing offers and was awarded the chance to build several staircases in concrete. His alternative worked, leading to contracts for more than 50 staircases and platforms for the Interborough Rapid Transit. The company established branch offices to maintain its expanding geographic scope, beginning with an office in Philadelphia in 1907. The Buffalo office followed in 1908, as did the office in Boston, opened in 1916. When the United States entered World War I, Turner was among the country's most successful builders. In its first 15 years, Turner Construction Company completed $35 million worth of work and constructed buildings for some of the country's largest businesses, including Western Electric, Standard Oil, Kodak and Colgate.
