History The company was founded in 1884 as Kiewit Brothers Masonry Contractors by Peter and Andrew Kiewit, who were of Dutch descent. Their father, John Kiewit, emigrated from The Hague in 1857, where he learned the trade of brickmaking. John Kiewit established a brickyard in Omaha, Nebraska where his sons worked and learned the skills for their masonry business. Early projects included the seven-story Lincoln Hotel in Lincoln as stonemasons and the Bekins warehouse as general contractor. It is an employee-owned company. The original brothers dissolved their partnership in 1904 and the founding Peter Kiewit continued as a sole proprietorship. In 1912, two of his sons, Ralph and George Kiewit, joined their father as partners in the firm. One of their constructions was the Omaha Fire Department Hose Company No. 4 building, erected in 1913. When the founding Peter Kiewit died in 1914, his son Ralph led the company. George and Ralph Kiewit left the company. The founder's youngest son, Peter Kiewit Jr., joined the firm in 1919. He led the firm from 1924 until his death in 1979. Peter Jr. turned the firm into one of the largest construction companies in the world. He was also very active in the Omaha area, including leadership of the Knights of Ak-Sar-Ben. In 1931, Peter Kiewit incorporated the company as Peter Kiewit Sons’ Co. The firm began building transportation projects during the Great Depression. Walter Scott was also a key figure in the growth of Kiewit. Scott was initially hired to work on the tower project at the Nebraska State Capitol and spent the remainder of his career at Kiewit becoming chief engineer. Notable projects Throughout the 1920s the company built several historic buildings around Nebraska including the Livestock Exchange Building (1926), the Lincoln station (Nebraska, 1926–2012), the Nebraska State Capitol Tower (1927), Joslyn Art Museum (1928), and Union Station (Omaha)(1929). Between 1951 and 1966, Kiewit built Thule Air Base for the U.S. military in Thule, Greenland. Located on the northwest coast of Greenland, the base features a 10,000 foot runway. In 1969, Kiewit began construction of the 63rd Street tunnel between Manhattan and Queens. The
