Clark has grown from a small local excavator into one of the most experienced and trusted providers of construction services in the country. Today, our capabilities have diversified as we have responded to changing market conditions with new building types, delivery methods, and services.
Our roots trace back to 1906 when George Hyman founded a small excavating enterprise, the George Hyman Construction Company. Hyman was the first in Washington, DC to use a steam shovel, shown here performing site excavation at the Smithsonian’s Freer Gallery of Art in the early 1900s.

A. James Clark, our company’s namesake, was a renowned innovator and led the company’s evolution into a preeminent national contractor. Under his leadership, in 1996, the George Hyman Construction Company merged with our affiliate Omni Construction to become Clark Construction.
We have always sought to fill evolving client and market needs. Clark began building an extensive portfolio of self-performed trades in the 1960s, many of which spun off into specialized entities. In the following decades, a series of acquisitions propelled us toward new opportunities.
L’Enfant Plaza served as a turning point in the company’s history. By self-performing sheeting, shoring, and underpinning, the team was able to speed up work and complete the project ahead of schedule. This realization led to the formation of Clark’s first self-perform entity, Clark Foundations.
Shirley Contracting Company, founded in the 1970s as a heavy highway company, was acquired in 1993. Today, Shirley has grown into a leading provider of heavy civil construction in the Mid-Atlantic and is known for their creative engineering approaches and experience with alternative delivery methods.
In 1998, Clark acquired Guy F. Atkinson Construction, founded in 1926, a heavy civil contractor known for building massive government-sponsored public works projects, like the Grand Coulee Dam, pictured here, which was completed in 1942.
C3M Power Systems was founded in 2014 as part of strategic efforts to grow the company’s civil capabilities. C3M self-performs the construction, reconstruction, and maintenance of electrical systems, primarily in the transportation market.
In the 1970s, we began to chart a path of growth that propelled us from our status as a local contractor into the nationwide company we are today. Our iconic projects now span the United States from Washington, DC to Washington State.
