Reshaping America’s Civil, Urban & Marine
Infrastructure Since 1976

NASDI, LLC, established in 1976, is one of the leading demolition and site redevelopment contractors in the United States, performing demolition, salvage/recovery and environmental remediation services for many of the nation’s most prominent corporations, institutions and government agencies.

Since 2000, NASDI has become a wholly owned subsidiary of Great Lakes Dredge & Dock Corporation, a Chicago-based, publicly traded, international company operating in two reportable segments – dredging and demolition. NASDI operates across multiple construction segments itself – commercial, industrial and heavy-civil.

Every NASDI project has a simple, defined purpose – to maximize the recovery of their clients’ investments, to responsibly transport and dispose of all debris and to protect the health and safety of their workforce, the public and the surrounding community.
