About Shimmick

At Shimmick, we are problem solvers. Creative thinkers. Innovators. We approach each project with fresh ideas and big thinking in pursuit of better answers, better outcomes, and better experiences for our clients. We are resourceful, nimble and resilient. We work hard together—and with our clients—to deliver high-quality projects that are on time, on budget and beyond expectations.

We are a market leader in heavy civil infrastructure, focusing on water, transportation, and transit projects. We also offer expertise in deep, complex foundations through our operating company, Legacy Foundations, as well as mechanical, electrical and plumbing; mining infrastructure; and O&M services.

We leverage our deep construction history and experience across many markets to provide diversified construction experience, passion, and expertise to our clients and partners. Over the past two decades, Shimmick has delivered projects in more than 20 states from coast to coast, with more than 2,500 employees.

Shimmick* ranks among the Top Contractors in the following categories:

  • 3rd largest Dam Contractor
  • 11th largest Water Supply Contractor
  • 10th largest Domestic Heavy Contractor
  • 11th largest Transportation contractor
  • 14th largest Mass Transit and Rail Contractor
  • 14th largest Bridge Contractor

In January 2021, Shimmick began operating as an independent company following a definitive investment from Oroco, a strategic long-term infrastructure investor with a focus on water, transportation, and transit projects. Shimmick operates as an independent company with renewed commitment to ongoing investments in its employees, technology, and equipment. As a privately held company, Shimmick enjoys greater control over business operations and strategic direction, while continuing to create value for our clients. Shimmick operates in the market as a stand-alone construction company under the Shimmick name and brand.

*Shimmick revenue reported as AECOM in the 2020 contractor rankings.

At Shimmick, you’ll get the training, support and tools to perform your work safely and to become a leader in workplace safety. If it can’t be done safely, we won’t do it. We care about your safety and health—because we know we’re not the only ones counting on you.

Core Values

Shimmick’s mission empowers people to imagine, plan, build and operate high-quality, complex projects in partnership with our clients. Our core values – Safety, Achievement, Transparency, Empowerment and Responsibility, Authentic Relationships, and Mutual Trust and Support – guide this mission and everything we do.


In 2017, Shimmick merged with an existing civil construction company, comprised of heritage companies Washington Group International, Morrison Knudsen, and others dating back to the 1960s. Today, Shimmick and these legacy companies operate as a single, integrated entity under the Shimmick name and brand.
