Cities rise through ambition. Skylines shift as new towers rise, campuses expand, and transportation networks stretch further into the future. Behind many of these complex developments stands Clark Group, a company that has spent more than a century delivering assets that shape how communities live and work.
With roots in the DMV, the company has grown into one of the largest building and infrastructure contractors in the United States. Its work spans corporate headquarters, cultural institutions, universities, entertainment venues, data centers, advanced manufacturing facilities, aviation, and the infrastructure supporting modern cities.
Each project introduces its own complexity. Deadlines remain demanding. Expectations remain high. The finished result must perform for decades. “Construction is about more than delivering a finished structure,” says Group CEO Ryan McKenzie. “Every project represents a commitment to the people who will rely on that building or infrastructure for decades. Our responsibility is to deliver something that betters our communities and performs at the highest level.”

From Local Builder to National Leader
The company traces its origins to 1906, when it began as a small excavation business. Overtime, expansion followed a consistent pattern as market needs evolved and capabilities expanded to meet them.
During the 1960s, the company developed self-perform trades that allowed project teams to manage critical construction scopes directly. These capabilities supported the delivery of increasingly complex projects as the organization expanded from a local contractor to a nationwide construction provider, spanning from Washington, DC, to the Pacific Northwest.
Long-term client relationships remain central to that growth. Organizations that partnered with the company decades ago continue to work with its project teams today, reflecting consistent performance across projects of varying scale and complexity. “Trust develops over time,” McKenzie explains. “Clients depend on us to manage the risk, solve challenges quickly, be adaptive to their evolving business needs, and deliver high-quality results. When you do that consistently, partnerships grow stronger with every project.”

Innovation Powered by People
Across the construction industry, digital tools, automation, and data systems continue to influence how complex projects are planned and delivered.
Within the company, innovation focuses on how these capabilities support the professionals managing the delivery of construction projects, both large and small. More than 5,000 employees contribute expertise across engineering, project management, digital construction technologies, safety programs, quality, and logistics.
The company’s workforce is the primary engine of innovation. By bringing diverse perspectives to the table, teams cultivate new ideas and develop more effective solutions. This progress is not a result of technology alone, but rather stems from people who are willing to ask better questions and discover more efficient ways to build.
Internal initiatives push teams to experiment with new ideas. Programs such as Build-a-Thons bring employees together to explore emerging technologies, while the Summer Associate Capstone program invites early-career professionals to develop new project concepts and strategies. “Innovation thrives when people feel encouraged to ask questions,” says McKenzie. “Curiosity often leads to breakthroughs that improve how we build.”

Raising the Standard for Safety
Innovation within the company is closely tied to jobsite safety. In 2017, Clark became the first general contractor in the United States to require employees to wear safety helmets with chin straps on all projects, providing stronger protection against traumatic brain injuries and other head injuries. Five years later, the company expanded the requirement to include all trade contractors working on its jobsites nationwide. “When you identify a safer approach, the next step is simple,” says McKenzie. “You implement it. Protecting the people who deliver these projects must always come first.”
The decision influenced safety expectations across the broader construction sector and standardized the industry.

Building What Comes Next
Infrastructure will continue to expand as cities grow, transportation systems modernize, and building technologies evolve. By investing in digital tools, integrated project delivery systems, advanced construction management technologies, and most importantly, its people, Clark positions itself to be at the forefront of supporting increasingly complex projects. Operational decisions remain guided by core values emphasizing responsible leadership and consistent performance. More than a century after its founding, Clark Group continues to demonstrate how innovation, disciplined execution, and industry expertise shape the built environment across the United States.
