Kiewit

Kiewit is a construction and engineering organization whose roots date to 1884, when brothers Peter and Andrew Kiewit formed a masonry contracting business in Omaha, Nebraska. The company says it has grown into one of North America’s largest construction and engineering organizations, delivering energy and infrastructure projects. Its original work focused on bricklaying; it later expanded into general contracting, highways and public works. Kiewit provides integrated engineering, procurement and construction (EPC) services and describes its approach as bringing project delivery capabilities together in a one-team model. Its stated markets include building, industrial, marine, mining, oil, gas and chemical, power, and transportation. The company also highlights nuclear work and projects involving transportation infrastructure, power generation and delivery, and marine construction. Its work ranges from feasibility and design through project execution. The company reports that it is employee-owned and operates through a network of subsidiaries and decentralized offices. Kiewit Development, its development, investment and asset-management arm, works on U.S. and Canadian public-private partnerships, alternative procurement projects and private-client work. Its homepage reports more than 140 years of construction experience and lists 2025 revenues of $18.2 billion; these are company-provided figures.

Kiewit traces its origins to 1884, when brothers Peter and Andrew Kiewit formed Kiewit Brothers, a masonry contractor in Omaha, Nebraska. The firm initially focused on bricklaying. In 1900, the brothers undertook the Bekins Warehouse in Omaha, which the company identifies as its first commercial building project as general contractors. A later generation of the family became central to the company’s development. Peter Kiewit’s youngest son, also named Peter, joined the business in 1924 as a superintendent on the Livestock Exchange Building project in Omaha. The company’s history describes that project as its first million-dollar project. In 1931, the younger Peter dissolved the family firm and reorganized it as Peter Kiewit Sons’, Co., establishing a form that led toward the modern company. Under Peter Kiewit’s leadership, the business diversified into highway and public-works projects. In 1932 it won a major highway contract for grading and paving a 25-mile stretch in Nebraska. In the mid-1930s, it expanded highway work into neighboring states, including Wyoming, Colorado and North Dakota. During World War II, Kiewit undertook defense-related construction, including military bases, airfields and shipyards. The company describes its subsequent development as growth from a local masonry contractor into a major North American construction and engineering organization. Its present-day activities include construction and integrated engineering, procurement and construction services across infrastructure and energy markets. The company emphasizes a project-delivery model that combines capabilities from feasibility through design and execution, as well as a network of subsidiaries and decentralized offices. It reports that it is employee-owned. Kiewit Development is the company’s development, investment and asset-management arm. It supports Kiewit’s design and construction activities and works on U.S. and Canadian public-private partnerships, alternative procurement projects and private-client work. The company’s current website presents the organization as active across a broad range of markets, including transportation, power, marine, mining, industrial, and oil, gas and chemical work. The supplied company material does not provide a full dated account of later corporate milestones, so later events are not specified here.
