Shirley Contracting Company, LLC

What Shirley Contracting Company, LLC does

Shirley Contracting Company, LLC is a privately held heavy civil and transportation infrastructure general contractor headquartered in Lorton, Virginia, founded in 1974 and operating as a wholly owned subsidiary of Clark Construction Group since 1996. The company serves public-sector clients — principally the Virginia Department of Transportation (VDOT), the Maryland State Highway Administration, and county governments across Virginia — alongside private developers and property owners' associations in the Mid-Atlantic region. Shirley delivers highway and bridge construction, interchange reconstruction, utility infrastructure, site development, and heavy civil work, with project values ranging from under $10 million to over $500 million.

The company operates through four integrated divisions: Shirley Contracting (core heavy civil and design-build delivery), Shirley Underground (hydro-excavation, pipe cleaning, slip-lining, and CCTV inspection established 2018), Metro Earthworks (site excavation and grading established 1999), and Shirley Asset Management (a fleet of over 400 trucks, trailers, and heavy equipment pieces). It has executed more than 50 design-build and Public-Private Transportation Act (PPTA) projects valued at over $4.5 billion over more than 20 years, with its primary design partner being Dewberry Engineers on most VDOT-led work.

Shirley's revenue is generated through competitively bid and negotiated construction contracts — typically fixed-price, project-based, non-recurring engagements — with the majority of work acquired via RFQ/RFP processes administered by VDOT, Maryland SHA, and Virginia county governments. Delivery methods include design-bid-build, design-build, and PPTA/PPP frameworks, with self-perform capabilities in earthwork, utilities, paving, bridge, and underground reducing subcontractor dependence. The firm is privately held under Clark Construction Group and does not publicly disclose revenue.
