Place of performance spans Camp Lejeune, North Carolina and subordinate locations including Marine Corps Air Station/Camp Johnson, French Creek, Hadnot Point, Camp Geiger, Courthouse Bay, and Wallace Creek. The project is divided into two packages: Package 1 covers eight buildings at Marine Corps Air Station/Camp Johnson; Package 2 covers 34 buildings across the other locations. Estimated cost ranges from one million to five million dollars, with contract completion 365 days after award. Award will be made on a lowest price basis with a 60-day proposal acceptance period.
