The firm was founded in 1970 in Clifton, New Jersey and added environmental services in 1985, which is when it became a single source for most of the issues in a development from the ground down. Langan International, a wholly owned subsidiary headquartered in New York, supports projects in the Middle East, Europe, Asia, Central America, South America and the Caribbean. Fees are project-based and not published.
