Grunley Construction Company

Grunley Construction is a Rockville, Maryland general contractor founded in 1955 that specializes in federal and institutional work across the Washington, D.C. region. The firm has built a reputation on complex renovations and modernizations of government buildings, courthouses, museums and secure facilities, often on occupied sites that have to keep running during construction. Grunley was among the six contractors selected to share the Navy’s $8 billion NAVFAC Washington construction contract, a market it has worked in for decades. Its focus on the capital region’s federal building stock makes it a steady presence on public-sector projects most national firms treat as a specialty.
